CHAPTER I

EXCITEMENT ON THE WEST FORK

Leaving the main branch of Delaware Creek, a broad, sluggish stream thatslowly made its way toward the muddy Pecos River, a party of horsementurned up the west branch. 

Horses and men alike were wearied, dusty, perspiring and sleepy underthe glare of a midsummer Texas sun. Little had been said for sometime. None felt like talking. For hours they had been working southby west, urged on by the green of the foliage that they could see ashort distance ahead. At least it had seemed a short distance for thelast five hours, but the green trees now appeared to be just as faraway as when the party had first sighted them early in the morning. 

At the head of the line rode a grizzled, stern-faced man, sitting onhis pony very stiff and erect. Just behind him was a young man, slender, fair haired and smiling, despite the discomfort his red faceshowed him to be suffering. Still back of them rode three other youngmen, the last in the line being a disconsolate fat figure of a boy whoslouched from side to side in his saddle, each lurch threatening toprecipitate him to the ground. The boy's pony was dragging alongwith nose close to the earth, the bridle rein slipping lower and lowerover the animal's neck. The fat boy was plainly asleep. He had beenslumbering in the saddle for more than an hour, and occasionalmutterings indicated that he was dreaming. 

"Professor, don't you think we had better make camp and take a rest?"asked the first boy in the line, addressing the grizzled leader. 

Professor Zepplin cast a critical glance down the line of jaded horsesand riders, a faint smile twitching the corners of his mouth. 

"All tired out, eh, Tad?" he questioned. 

"Yes, I'll confess that I am for once. Of course I can stand it aslong as the next one, but there's no use in wearing out the stock, "answered Tad Butler. "Chunky's asleep. Ned and Walter will be in afew minutes more. "

"Very good; call a halt. We will ride into the bushes over there onthe other side of the stream. The water cannot be deep. Some hotcoffee will wake us all up. "

"Hoo---oo!" cried Tad, interrupting the professor. "Wake up, fellows, and make camp!"

"Wha---what's up?" demanded Ned Rector, straightening in his saddle. 

"Nothing's up, except ourselves, and we'll all be down in a minute. We're going to ford the stream and make camp on the other side. "

"Is this the Guadalupe range?" asked Walter Perkins sleepily. 

"This is the loop all right, but not the Guadalupe, " laughed Rector. "Hullo, Chunky's in the Land of Nod. "

"Wake him up, Ned, " nodded Tad. 

"Not much. Let him wake himself up. "

"His pony has gone to sleep, too, " added Walter. 

"Yes, they are a couple of sleepy heads, Tad. "

As the lads turned to gaze at the fat boy, they could not repress ashout of laughter. Stacy Brown's pony now stood the picture ofdejection, its nose clear to the ground. Chunky had settled in hissaddle until it seemed that the boy was less than half his naturalheight. His body had fairly telescoped itself. The fat boy satleaning forward, his sombrero tipped forward until it covered his face, leaving only the point of the chin exposed. 

By this time Professor Zepplin had driven his own pony into the creek, the others following, where the horses drank greedily. Stacy and hismount were still on the bank, too sound asleep to think of either wateror food. 

"Stacy!" shouted the professor. 

"Oh let him sleep, " begged the boys. 

"Too bad to disturb his infantile slumbers, " jeered Ned Rector. 

"But he will fall off. "

"It wouldn't be the first time, " laughed Tad. "Gid-ap!"

The ponies climbed the opposite bank, the tired Pony Riders throwingthemselves off and quickly stripping the equipment from their mounts. They then led the animals farther into the bushes, where the ponieswere tethered until they should be wanted again. 

Chunky still slumbered on. 

In the meantime Tad was carrying water from the creek, while the othertwo boys were starting a fire on the bank, the smoke from which wasalready curling up lazily into the still, hot air. But not much of ameal was cooked. It was too hot to eat or to cook. The boys sat downto their little meal, almost choking with laughter every time theyglanced across the stream toward the sleeping pony and its sleepingrider. 

"Most remarkable, " nodded the professor. "Surely the smell of foodought to awaken him if nothing else does. "

"He's just as much of a sleeper as he is an eater, Professor, " declaredRector. 

"That would be impossible, " objected Tad. "As an eater he is achampion, as a sleeper he is just above the average. You're thechampion sleeper of this outfit, Ned. "

"It's too hot to resent your unseemly remarks, Tad. I'll take thatmatter up when we get to the mountains. By the way, how much fartheris it to the mountains?"

"Just as far as it was this morning. How about it, Professor?"

"We ought to reach them this afternoon. According to my understanding, we were a little more than forty miles from them this morning. Sincethen we have gone a good twentyfive miles. "

"Then we will camp there to-night?" questioned Walter. 

"Yes, I hope so. "

"What are we going to do about Chunky?" demanded Walter. 

All eyes were directed toward the sleeping fat boy and his slumberingpony. The latter was now beginning to show some signs of life. It hadlifted one foot, then another, until it had taken two steps toward thecreek. But the rider was as soundly asleep as before. Nothing seemedto disturb Chunky when he was having a nap. 

"He will fall off. Wake him up!" commanded the professor. 

"Oh, please don't bother him. We want to see what he will do, " beggedWalter. 

"I think you will see, all right, " chuckled Tad. "You will see what youshall see, and---"

"There he goes!"

The pony had taken three or four more steps toward the stream. Now itseyes were partly open. It saw the rest of the party on the other sideof the creek. 

The cool water completed the awakening process for the horse. It drankfreely then started for the other side, Chunky still sleeping. All atonce the pony stepped into a deep hole in the creek. The animal wentdown on its nose with a mighty splash. Stacy shot over the disappearinghead, then boy and pony vanished under the waters of Delaware Creekwhile the others of the party bowled with delight. 

"Oh, wow!" howled Stacy, coming to the surface and making for shore withmighty splashes, coughs and chokings. "Oh, wow!"

Walter ran down to the water's edge, lending the unfortunate fat boy ahelping hand. The pony in the meantime had clambered up the bank andwas trotting off to join its fellows. 

"What---what---who did that?" demanded Stacy belligerently. 

"Did what?" replied Ned. 

"Who threw me in?"

"I reckon you threw yourself in, " answered Tad. 

"I didn't. "

"The pony did it for you. Don't be a goose, " commanded Ned. 

"Yes, you went to sleep. You've been asleep for the last ten miles orso, " nodded Butler. 

"I'm all wet, " wailed Stacy. 

"You will be dry in a few moments in this hot sun, " interposed theprofessor. 

"I don't want to be dry. "

"Then jump in again, " suggested Butler. "Anyhow, you've missed yourdinner. "

"I---I've---what?"

"Missed your dinner. "

Chunky's gaze wandered from the camp fire to the dishes and provisionsthat already were being packed preparatory to moving on. 

"I want my dinner, " he wailed. 

"Dinner is finished, young man, " replied the professor severely. "Youshould be on hand when meals are being served. There is no secondtable in this outfit, except for good and sufficient reasons. "

"My reasons are good. I---I fell in, I did. And---say, why didn't youfellows wake me up?" demanded the fat boy, a sudden suspicion enteringhis mind. He began to understand that a trick had been played upon him. "What'd you let me sleep for?"

"Because you were sleepy, " answered Ned Rector solemnly. 

"That's a mean trick. I wouldn't play that on a horse, " answered Stacyindignantly. 

"But you did play it on a horse, " spoke up Tad. "The horse went tosleep with you, out of sheer sympathy I should say. "

"I should think he would have. Anything would go to sleep with Chunkyon hand, " declared Ned. 

"You fellows are too funny! I don't care what you think. I'm going tohave something to eat. Where's the biscuit?"

"Packed. "

"Then we'll unpack them again. I guess I've got as much right to thegrub of this outfit as the next one. "

With that Stacy helped himself to such of the food as he was able tofind. In order to get what he wanted he was obliged to undo three ofthe large packs. Once undone no one would help him lash them togetheragain, so grumbling and growling, the fat boy tugged with the ropesuntil he had taken a secure hitch about each of the three packages. They made him tie the three before they would allow him to eat thebiscuit and cold bacon that he had got out. 

While Stacy was munching his cold lunch the others were lashing thepacks to the lazy ponies and preparing to start again, every one beinganxious to reach the mountains before night fell. But the fat boy wassurly as well as sleepy. He felt aggrieved. That his companionsshould sit down to a meal, leaving him asleep on his pony, filled Stacywith resentment and a deep-rooted determination to be even with them. He was already planning how he could repay his companions in theirown coin. 

"Better not try it, " suggested Tad carelessly as he passed the fat boyon his way to get his pony. 

"Try what?"

"To get even, " answered Tad laughingly. 

"How do you know that I was thinking of such a thing?"

"Perhaps I read your mind. "

"Humph! You better learn to read your own before you go prying into mine. I'll show you what I'm going to do. "

"Cinch up, " interrupted the voice of Professor Zepplin. "We have notime to waste. "

Still grumbling, Stacy climbed into the saddle. He promptly fell off, having forgotten to cinch the saddle girth. Now the pony woke up andbegan to kick as the saddle slipped under its belly. Stacy moved morequickly than he had at any other time during the day. Over and overhe rolled in a cloud of dust in his efforts to get out of the dangerzone, while the pony kicked and squealed, the boys shouting withlaughter. 

"Whoa!" roared the fat boy, sitting up after he had reached a placewhere he considered it safe to do so. "Whoa! Catch him, somebody. "

"Catch him yourself, " retorted Ned. 

Tad's rope wriggled through the air. It caught one of the flying hindfeet of the pony. Then the little animal plowed the dirt with its nose, while Walter sprang forward, sitting down on the angry animal's head. 

"Now get that saddle off, " commanded Tad. "Come, Chunky! Do you thinkwe are going to wait here all day for you?"

The fat boy reluctantly obeyed the command of Tad Butler. After somefurther trouble, Stacy's pony was properly saddled, but still stubbornand ready for further trouble. The lad got on this time withoutfalling off, and with much laughter and joking, the party started offtoward the blue haze in the distance, the dark ridge that marked theGuadalupes. 

It was in "_The Pony Rider Boys in the Rockies_" that our readers firstlearned how this little private club of youthful horsemen came to beorganized. The need of open-air life for the then sickly WalterPerkins was one of the great factors in the organization of thislittle band of rough-and-ready travelers. Our readers remember theadventures of our young friends in the fastnesses of the RockyMountains. These lads speedily fitted themselves into the stirringlife of the big game land, and had other yet more startling adventuresin which wild animals did not play so strong a part as did wild men. The story of the discovery of Lost Claim, with its accompanyingbattle with claim-jumpers, was fully told in this first volume. 

It was in "_The Pony Rider Boys In Texas_" that we found the ladslearning the first rudiments of the cattle business. The thrillingpart that the young men took in the long cattle drive, with itsstampedes, the fording of swollen rivers, the games of the cowboysand the tricks of the cattle thieves, is related in that secondvolume. How the boys improved their shooting and mastered the detailsof that fascinating sport of handling the lariat are all familiarto our readers. 

In "_The Pony Rider Boys in Montana_" is told the story of the longand exciting ride over the old Custer Trail, famous in the tragicannals of our earlier days of Indian fighting. Here the boys foundthemselves drawn into the life of the sheep men, on those greatranges where the sheep men must still defend themselves from theprejudices, and sometimes from the extreme violence, of the cattlemen. It was in this connection that Tad Butler and his friendsdiscovered leading clues in the great conspiracy of certain cattlemen against the prosperity and safety of the sheep men. This stateof affairs led finally to an angry battle, at which the boys werepresent. Then, too, our readers all recall Tad Butler's capture bythe Blackfeet Indians, and all that befell him ere he succeeded inescaping to his friends. 

The next stage of adventures took our lads somewhat further east, astold in "_The Pony Rider Boys in the Ozarks_. " It was a thrilling, desperate time when the boys, with their ponies stolen, found themselvesfacing actual starvation in the wilds. Tad Butler's perilous trip forassistance is bound to bring throbs of recollection to every reader ofthat volume. The imprisonment of the youngsters in a mine, following abig explosion, formed another interesting scene in the narrativebrought forth in that fourth volume of the series. It was here thatChunky, as our readers know, displayed the splendid stuff that lurkedunder his odd exterior and behind his sometimes queer manners. How, in escaping from the mine, the Pony Rider Boys penetrated a mysterythat had disquieted the dwellers near the Ozarks for a long time, wasone of the most interesting features of the tale. 

But such strenuous life proves the mettle of the right kind of youngAmericans. So, far from being discouraged, or sighing for the comfortsof home, we next find our lads in Nevada, as related in "_The PonyRider Boys on the Alkali_. " Here they left grass behind for theglaring discomforts of the baked desert lands, where severe thirstwas one of the least yet most constant perils. Roving from water holeto water hole, finding them all gone dry, nearly drove the youngstersmad. Then, too, the fight with the mad hermit, who seemed a part ofthe life of that bleak desert, helped to accustom the boys to thestrenuous life of daily danger. 

As our readers will recall, it was in the next volume, "_The Pony RiderBoys in New Mexico_, " that the author described the events surroundingthe first real acquaintance that our lads formed with the little thatis left of the savage Indian to-day. It was here, too, that theybeheld the fire dance of the Saboba Indians in all its ancient fury. The adventures of the young horsemen at this point became fast andfurious. Between prairie fire and fight they had the most excitingtime of their lives. 

Later, after a rest at home, as described in "_The Pony Rider Boysin the Grand Canyon_, " the boys visited the wonderful region of theColorado. Here, as our readers will recollect, the lads were cut offfrom their trail by the falling of great masses of rock during afierce storm. Apparently the boys were doomed to remain helpless ona narrow shelf of rock; our readers recall how Tad Butler, at therisk of his life, spent hours in the attempt to get them out of theirdangerous situation. The mysterious circumstances that followed theboys all the way along on their journey through the great canyon forma most remarkable series of events. 

Now, from Arizona, Tad and his friends had journeyed onward and intothe Lone Star State. Here they looked forward only to a long, healthful ride, full of pleasures, yet devoid of anything likesensational excitement. Yet one never knows what the day may bringforth, and these young travelers of ours, though they did not suspectit, were on the threshold of the most exciting experiences that had yetbefallen them. The blue mountain ridge in the near distance was teemingwith the story that was to unfold before them. So far the ride hadbeen lonely. Of late rarely had they come in sight of a building ofany sort, for this part of the state was but sparsely settled. To meeta horseman was an event. In fact they had not met one since the earlymorning. The Pony Riders had no guide with them on this journey, believing that one would not be needed. Nor did they carry a pack train. One additional pony bore all their extra baggage, each mount beingloaded with all that he could carry in addition to its rider. For tentsthey had brought one large enough to accommodate the entire party. This was in sections, carried on the different ponies. 

Five o'clock had come and gone. The sun was partly bidden by the ridgeof the Guadalupes towards which the Pony Rider Boys were slowly drawing. Ned called up to the professor who was riding at the head. 

"Where are we going to make camp, Professor?"

"Tad will decide that, " answered Professor Zepplin without looking back. 

"Near a stream, of course, " answered Butler. 

"Any mosquitoes there?" demanded Stacy. 

"No odds, if there are, " retorted Ned. "They wouldn't bite you. "

"Not if they had got at you first, " returned Stacy solemnly. "There'sa level place in there by the creek. "

"I see it. I'll ride on and have a closer look at it. "

Butler spurred his pony ahead of the others. Reaching the foothillsof the range he shaded his eyes, gazing up into the cool, green valleyor canyon that led into the mountains. 

"I guess this will do very well, boys, " he said. "I---"

Bang!

"Wow!"

Stacy with a howl of terror slid from his pony, sending up a littlecloud of dust as he collapsed on the plain. 

"Wha---what---what-----" gasped the professor. 

Bang!

Professor Zepplin's sombrero was snipped from his head. Stacy laygroaning on the ground. 

"Ride for the rocks!" shouted Tad as shot after shot began popping fromsomewhere in the mountains, the bullets screaming over their headsclose to their ears or snipping up flecks of dust in the plain. 

Tad drove his pony straight at Stacy Brown. He scooped the fat boy upby the collar and rode madly for the protection of the rocks, Chunky'sheels dragging on the ground. The others rode madly after them, whilethe shots were still being fired at them. It was an exciting moment. No one knew what the shooting meant, nor did they know whether Stacyreally had been hit or not. There was no time to stop to reason thematter out. It was a case of getting to cover as fast as horse-fleshwould carry them. 

CHAPTER II

A MYSTERIOUS ATTACK

"Pull in close!" cried Tad. 

"Where is it coming from?" shouted Ned. 

"I don't know. I haven't had time to look. Look out there!"

Professor Zepplin, somewhat slower than the others, had halted a littledistance out from the foothills. A bullet threw up a little cloud ofdust just to one side of where he was sitting on his pony, followed bya report somewhere up in the mountains. 

"Stop that! Stop it, I tell you!" bellowed the professor, waving hissombrero. Almost ere the words were out of his mouth, the sombrerowas shot from his hand and went spinning out to the rear. ProfessorZepplin did not wait for further parley. He turned his horse, dashingfor the protection of the foothills. 

In the meantime, Tad Butler had leaped from his pony, placing Stacy onthe ground. It was observed that there was blood on the fat boy's leftcheek, but his eyes, wide and frightened, were staring up at the boysnow gathering about him. 

"Are you hurt?" demanded Tad breathlessly. 

"I'm killed. "

"Nonsense! It's only a flesh wound---"

"Is---is he shot?" stammered Walter Perkins. 

"Of course I'm shot. Don't you see I am?" demanded Chunky withconsiderable spirit for a man who had been the mark of a bullet and whoaccording to his own word was dead. 

Tad half dragged the fat boy down to the creek where the blood wasquickly washed from his cheek. It was then seen that a bullet hadgrazed Stacy's cheek, leaving a raw streak across it. 

Professor Zepplin, now mindful of his duty, had hurried up to them, anddown on his knees was examining the wound critically. 

"Hm---m---m!" he muttered. "Bad business, bad business!"

"But---what does it mean?" urged Walter. 

"What does it mean? It means that the Germans have got us, " wailedStacy Drown. "Oh, I knew we should be in this war sooner or later, but I didn't think I should be the first man to get shotted up. "

"It means some one has been trying to shoot us up, " answered Rector. 

"Trying!" exploded Chunky. "They did more than try. They succeeded. Don't you see this wound on my countenance? Wait till I get sight ofthe man who put that mark on my face. I'll bear the scar for life. I-----"

"It is my opinion that we are in a dangerous position, " declared theprofessor, getting up and glancing about him apprehensively. 

"We were. We are all right here for a little while, " replied Tad. "But we shall have to seek other quarters, I am afraid, and thatwithout delay. "

"Surely, it must be a mistake, " protested the professor. "Some onemust have been shooting at us under a misapprehension that we wereanother party. "

"It doesn't make any difference what their motive is, sir, " answeredTad. "The fact remains that some one is trying to get us and we mustlook lively or they will pink one or more of us. Get up, Stacy! Youare all right. Lead your pony in here while I take an observation. "

Tad mounted his own horse and galloped along at the base of the rocks, well shielded from any one who might be hiding further back in themountains. The Pony Rider Boy's mind was working rapidly. He wasforming a plan of campaign. He was inclined to agree with the theoryof Professor Zepplin. Still, theories would not help them at thiscritical moment. They must protect themselves and at once if theyexpected to get out alive. One course was plainly open to them. Theycould mount their ponies and ride out over the plains at a gallop andperhaps escape. However, this plan was rather risky. Besides, Taddid not like the idea of running away. 

"No, we've got to do something else, " he declared out loud. "I haveit!" The boy brought his pony up standing and gazed off over the plainto a point about a quarter of a mile beyond, where the plain rolledinto a hollow, a "hog hollow" as it was called down there. 

Butler galloped back to where his companions were standing anxiouslyawaiting him. 

"We are wasting time, Tad, " cried the professor as the lad rode up. "It is my opinion that we had better ride into that canyon there andmake camp in some secluded spot where we shall not be easily found. "

"I am afraid that won't help us any, Professor, " said Tad. "Howcould we expect to hide ourselves in there so completely that amountaineer would not find us? No, sir, it is my opinion that ouronly safety lies out there in the open, at least for the rest of theafternoon and the night. "

"What, ride out there to be shot up again?" demanded Stacy. "No, sir, not for Stacy Brown! I've been shot up once. I don't propose to makea bull's-eye of myself again. "

"Stacy is right, boys. It would be foolishness to follow such acourse and---"

"Wait till you hear my plan, sir, " urged Butler. 

"We will hear it. Proceed. "

"Out yonder about a quarter of a mile from the base of the rocks is adepression in the plain. If we can reach it we shall be safe---"

"Yes, if we can reach it, " repeated Ned. 

"In doing so we should be shot in all probability, " objected ProfessorZepplin. 

"I think not, sir. "

"Explain what you mean?"

"From the position occupied by the man or men when they fired at usout there, I am sure they could not see us were we to follow thecourse I went out on just now. If you will ride down to the edge ofthe foothills with me and wait there, I will gallop out and prove mytheory. "

"What do you mean?" questioned the professor. 

"I will see if I can draw their fire, " answered Tad. 

Professor Zepplin shook his head. 

"Too risky!"

"It certainly is risky to stay here. Listen, sir. If that man wantsto get us he surely will be creeping down on our position before long. We are in greater peril here, where we can't see anything on one sideof us, than we would be out there where we have an unobstructed view onall sides. My plan is to make camp out in the hollow; then we willplace a guard over the camp, keeping a sharp watch all through thenight. By morning we'll be able to find out what is in the wind. "

"I won't move a step, " declared Stacy stubbornly. 

"You will do whatever seems best to the rest of us, " answered theprofessor sternly. Then, after a moment's thought, he added, "I aminclined, upon second thought, to agree with Tad. We will try the plan. "

"Good. Follow me. Get that pony, Chunky. I told you once before tocatch him. We'll be in a fine mess if you lose your mount. "

"I'd rather lose my mount than to lose my precious life, " answered thefat boy surlily. 

By this time the others were taking to their saddles. The faces of allwore serious expressions. They had not looked for anything quite solively as this. It was not the first time the Pony Rider Boys hadsmelled powder when the powder was being expended on them, but theyliked it none the better for past experiences. 

Stacy's cheek was bleeding again. He was holding his handkerchief tothe wound and his face was a little paler than usual. 

"Buck up!" commanded Ned. "You're not going to show the white feather, are you?"

"No, it's a red feather I'm showing, " wailed the fat boy. 

"Forward!" ordered Butler. "Get up, Chunky!"

The party moved off, keeping close to the rocks, Tad now and thencasting apprehensive glances up to their tops. He was not whollysatisfied that they were out of range of the bullets. The man whohad been firing at them, too, was practically a dead shot. 

"Now spread out, " commanded Tad after they bad reached the point wherehe previously had halted. "Don't shout, but when I wave my hand, ridefast for the hollow. I'll be all right; don't worry about me. "

With that the lad galloped leisurely out on the plain, his back to themountains. It was a bold thing to do. Deep down in his heart thePony Rider Boy expected every second to bear a bullet scream over hishead, providing he was fortunate enough not to stop the bullet withhis body. Not a shot greeted his bold act. 

Tad rode on, finally disappearing in the "hog hollow. " A few momentslater he rode up the ridge, waving his hands for them to come on. Professor Zepplin started out at once, followed by the others of hisparty, Stacy this time well up toward the front of the line. Forreasons of his own he did not care to drag behind. If there was tobe any shooting he wanted to be as far away from it as possible. 

The trip was made at a fast gallop and without incident, the partyreaching the hollow without having drawn a shot from the enemy. 

"It is my opinion, " declared the professor, "that, whoever our enemymay be, he has discovered that he has made a mistake. "

Tad shook his head. 

"I don't think we would be safe in taking that for granted. He did notsee us, but he will be on hand before long. I'm going back therebefore he does see us. If he starts any more shooting you all lie low. "

"Where are you going?" demanded the professor. 

"On a scouting trip. "

"I cannot consent to any such foolhardy business, " answered ProfessorZepplin sternly. 

"It is not foolhardy. We've got to clear up this mystery. Don't yousee, we shan't dare go any farther---we simply cannot go into themountains knowing there is some one there waiting to riddle us thefirst time he gets a clear sight at us?"

"But what do you propose to do?"

"I don't know, beyond finding out what is up. "

"Yes, let him go, " urged Stacy. "He's looking for trouble. I'm theonly one who has had any experience thus far. It's time some oneelse made a mark of himself. "

"I was thinking of taking you with me, " laughed Tad. 

"No, you don't! Not if I see you coming, " objected Stacy. 

"Yes, take him along, " urged Ned. 

"No, I think I'll take you, the Professor being willing, " answered Tadnodding at Rector. 

Ned stopped smiling, gazing at Tad to see whether the latter were inearnest. Tad was. 

"All right, I'm willing, Tad. "

"How about it, Professor?"

"Provided you do not go into the mountains I will agree to your plan. But I cannot consent to your taking further desperate chances. "

"I hope you will not hold me to that, Professor. "

"To what?" demanded Professor Zepplin shortly. 

"To not going beyond the edge of the mountains. "

"Plainly, what is it you are planning to do, Tad?"

"I want to find out who it is that is shooting at us and why. That isall, sir. "

"You don't suppose it possibly could be the Germans attacking us, doyou?" questioned Walter apprehensively. 

The professor shook his head. 

"If you will stop to think you will see how necessary it is for someone to do something, " urged Tad Butler. 

"Yes; don't let me do it all, " urged Stacy. "I think I have done myshare already. It is high time some one else got a move on. Firstthing we know we shan't know anything. We'll be dead ones, and---"

"Very good. Go on. There will be no peace here unless you have yourway. See to it that you are back here in an hour. If not we shall goafter you. Do you understand?"

"Yes, sir, I will try to get back on time. If something should occurto keep us longer than that please don't worry. You know we mightnot be able to get away. If we get into trouble I will signal byfiring three shots into the air. Are you ready, Ned?"

"Yes. Do we take our arms?"

"Better leave the rifles here. We don't want to be bothered with them. We'll take our revolvers. That will be sufficient. "

"Now, Tad, be prudent, " begged the professor. "I know you have a levelhead or I should not permit you to get out of my sight under thecircumstances. "

"We will be prudent, sir. Come on, Ned; we mustn't waste a moment now. If we are seen to leave the camp we'll fail. "

For answer Ned swung himself into his saddle, after first having takenthe rifle from the saddle boot and fastened it to one of the packs. 

"Don't pitch the tent yet. We must be in marching order, " directedButler, after leaping into his saddle. "And don't worry about us, forwe'll be all right. "

Nodding to Ned Tad started off at a fast gallop. But despite Tad'scheerfulness he realized that he had taken upon himself a seriouspiece of work, one that might be the death of both. Still, he wasnothing daunted. He was determined to go to the bottom of the mystery, whatever the cost might be to himself. 

Tad knew also that he could depend upon Ned Rector, for Ned was braveand resourceful, a boy who would keep his head in an emergency. 

They made the trip to the mountains without incident. There Tad pulledup for a conference. 

"Now tell me what your plan is?" said Ned. 

"First we will ride on a little further along the base here. I see aplace where I think we can hide our ponies. I don't want to go backto the point where we first started to make camp. That is the placewhere our enemy will be looking for us first. But when he gets therewe'll be somewhere in the vicinity. "

Ned wheeled his pony without further comment and followed Tad at a slowtrot along the base of the foothills. The boys were engaged on a moredesperate mission than they knew. 

CHAPTER III

IN A BAD MAN'S POWER

Having secreted their ponies in a dense growth of scrub oak, Tad laidout his plan as follows:

"You, Ned, will go straight in from here until you've got about aquarter of a mile directly inland. When you have done so turn due west. I don't think you can lose your way for you can see out every littlewhile and thus get your bearings. "

"Where are you going?"

"Back to the point where we first decided to make camp. I shall haveeasier going than you will, but I shall be in more risk. "

"What's the rest?" asked Ned with a short laugh. 

"It is my idea to close in on the right fork of the stream there in thefoothills. I'll come up from the west and you from the east. In thatway we shall close in, you see, covering roughly the greater part ofthe territory. "

"Then you think we shall find our man there?"

"I am sure he will get there eventually, provided he has not seen ourmovements out there. He will go to the stream and from there he willquickly locate our camp. Understand?"

"As far as it goes, yes. But what are we going to do if we find him?"

"Watch him. Find out what he is up to, then from that on be guided bycircumstances. But whatever you do, Ned, don't use your revolverunless it be to save your own life. "

"No, I'm not aching to shoot any one. Do you know, Tad, I'm thinkingyou and I are biting off a bigger mouthful than we will know how tochew?"

"We will manage it somehow. "

"What do you think this fellow is trying to do?"

"It looked very much as if he were trying to kill us, " smiled Tad. 

"It did. But what for?"

"I have an idea the professor was right when he said the fellow mistookus for some other party. "

"And he's likely to do it again, if that's the case. "

"He may have already discovered his mistake, Ned. You observe he hasn'tfired a shot since?"

Rector nodded thoughtfully. 

"Well, we must be on the move. We don't want to be caught out hereafter dark, you know, Ned. Remember, the right fork, where it entersthe hills, is the point we have agreed upon meeting. You will strikethe stream farther back, then follow it, but be very careful. Be anIndian, Ned. If you are a white man you're likely to lose youridentity. We don't want to stop any bullets. Chunky has done quiteenough of that for one day. "

"I'll watch out---never you fear, old man. "

"Then here we go. "

Tad crept silently away, hugging the base of the rocks so that it wouldhave been difficult for one at the top to have seen him at all Ned, obeying his instructions, found a canyon up which he crawled, neitherboy making a sound. They had agreed upon the two-shot signal to calleach other, three shots being a warning to the rest of their partythat they were in need of assistance. 

Neither lad saw or heard anything of a disturbing nature on his way out. Ned found no difficulty in making his way into the range of mountains, but as he proceeded and found no one there he grew more bold. Not thathe was particularly careless, but he unconsciously relaxed a little ofhis former caution. 

In the meantime Tad Butler had crept on past the place where the partyhad first planned to go into camp. Not a sign of a human beinggreeted Tad's watchful eyes. The lad climbed the side of the rocks, keeping his body hidden in the foliage as much as possible. He hadgot about half way up when he paused to take a look over the plainbeneath him. The Pony Rider Boy could faintly make out the placewhere his companions were in camp awaiting the result of his mission. 

"I believe there's Chunky standing on that rise, " muttered Tad. "Yesit must be Chunky. I'll bet the professor doesn't know the boy is outthere. Chunky evidently is getting anxious about us. "

Bang!

The shot sounded some distance to the eastward of where Tad wassecreted. Instinctively the lad glanced toward the camp again. Stacy Brown no longer was to be seen. Tad Butler could not repressa laugh. He had a pretty clear idea as to what had caused Chunky'ssudden disappearance. It did not occur to him that possibly Stacyhad been bit. As a matter of fact the unknown marksman's bullet hadgrazed the head of the fat boy, instilling in that young gentlemana more thorough respect for the mountaineer's marksmanship. 

But now Tad's mind turned to the object of his visit to the mountainrange. He was there looking for the man who had fired the shot. Ned Rector had heard the shot also. Both boys were making their waytoward the spot whence the shot had seemed to come. Ned had locatedthe sound much nearer than had Tad. The latter struck off in asoutheasterly direction which carried him still farther into the hills. He had reasoned that the shooter was occupying a high point of vantagesomewhere farther in, whence he was taking pot shots at the camp ofthe Pony Rider Boys. In this Tad was mistaken. The mountaineer wasmuch nearer the plains than Tad thought. 

Ned started on a trot immediately after having heard the shot. 

"I've got him this time!" exulted Rector. "I've got a chance to showthe fellows what sort of a trailer I am. They don't think I'm anygood, except Tad, and he knows better. "

Tad, as he skulked along, was wondering if Ned had heard the shot andhoping that his companion would make no false moves. Each boy wasdetermined to round up the man who had winged Stacy Brown and narrowlymissed killing the others of the party. 

Night was coming on rapidly and it behooved the lads to make haste. In the first place they did not know these hills, and, in the second, the professor would become alarmed and come in search of them weretheir return delayed too long. This was not desirable. It might meanthe undoing of the entire party unless Tad and Ned succeeded inrounding up their enemy first. 

Ned, in his excitement, had a mishap. While creeping along the upperrim of a galley he stepped on a round stone. Ned fell crashing intoa heap of rotting limbs and went floundering from there to the bottomof the incline, making a racket that must have been heard clear out onthe plain. 

The lad got up, his clothing torn, his face scratched, very muchchagrined over his blundering fall. 

"I guess I'm not so much of a scout as I thought I was, " he muttered. "Chunky could have done no worse and for a blundering idiot he'salways held the cup up to the present time. I'm glad no one saw memake such an exhibition of myself. But what if that fellow heard me?No, he couldn't. He is too far away. "

In this Ned was wrong. The "man" was not so far away as the Pony RiderBoy thought. The fellow, while watching for another opportunity toshoot, had caught the distant sound of crashing twigs. It might havebeen a falling tree, it might have been an animal. At any rate it putthe fellow instantly on his guard. Lowering his rifle he began skulkingin the direction of the racket. 

By this time Ned was walking ruefully down the galley looking for aconvenient trail up the side to the ridge. Not that he could not havemade the ascent anywhere, but that he did not wish to raise any moredisturbance than be already had done. At last, finding what seemedto him to be a path, Ned began climbing the side of the galley. Hadthe boy first taken a survey of the ground at the top of the rise, hemight possibly have made a discovery, and then again he might not. Crouched behind a rock was a man. The fellow was fingering hisrifle suggestively. Twice he raised it to a level with his eyes anddrew a bead on the advancing form of Ned Rector, and as many timeslowered it. 

The watcher observed that Ned carried no rifle, only a revolverslapping against his thigh in its holster as the boy stumbled on upthe mountain side. The mountaineer evidently changed his mind aboutshooting, for he changed ends with the gun and sat waiting. A fewmoments later Ned stepped up beside the rock where he stood listeningand looking about him. The Pony Rider Boy looked everywhere exceptin the right place. 

Suddenly there was a crackling of twigs behind him. Ned turned justin time to see the figure of a man leaping upon him. The boy wentdown under the crushing weight, the cry that rose to his lips smotheredby a stinging blow in the face. 

Ned lost consciousness. Everything turned suddenly black about him. 

CHAPTER IV

TAD BUTLER MAKES A DISCOVERY

Dusk was already settling over the mountains when Ned Butler fellbeneath the powerful onslaught of the mountaineer. Without an instant'shesitation the fellow picked up the boy, starting down the side ofthe galley with his burden. The man ran along carrying the lad aseasily as if he had been a child. 

Reaching a secluded spot near the west fork the fellow put his burdendown, then built a little fire under a thick growth of pines, whosetops served to break up the smoke and scatter it, thus greatly lesseningthe chances of discovery. 

It was a few minutes later that Ned regained consciousness. His captor, watching him narrowly, had placed Ned against a tree, passed a pieceof rope about the boy's body, pinioning his arms to his sides, securing the rope at the other side of the tree. Then the fellowhad squatted down with rifle across his knees. 

Ned saw a powerfully-built, wiry man, whose lean face and deep-sunkeneyes created a most unfavorable impression. Even under more pleasingcircumstances this man would have caused Ned to give him a wide berth. Discovering that he had been bound Ned's face flushed angrily. Eventhen he did not realize that his position was a perilous one. 

"You untie me and let me go, or it'll be the worse for you, " threatenedRector. 

"I reckon I've got you this time, " grinned the mountaineer. 

"I know you. You're the fellow who has been shooting at us. You willget what is coming to you when my friends find out what you have doneto me. What do you think I am anyway?"

"That's what I reckoned to find out, " answered the man. "Who be you?"

"That's what I am asking you. "

"I reckon I ain't answering fool questions. "

"Why did you shoot at us?"

"Did I?"

"You know you did. "z"What's your name?" asked the mountaineer, evading the question. 

"My name is Rector---Ned Rector. "

"Where you from?"

"Missouri. "

"What you doing here?"

"Maybe I am traveling for my health, " answered Ned with a half sneer. He was not advancing his own cause by his attitude. 

"I reckon you'll answer my questions and without putting on anytrimmings either, " announced the fellow, shifting his rifle aroundso that the barrel lay along his right leg, the muzzle pointingstraight at Ned. The latter was not greatly disturbed at this. He did not think, for a moment, that the man would dare to shoothim. Ned did not realize what a desperate character he was facing. 

"I will answer what I choose. You can't make me answer any questionsthat I don't want to, " declared Rector defiantly. 

"I reckon you'll change yer mind before I git done with you. Anybodywith you?"

"No, not exactly here, " answered Ned quickly, a sudden line of conductoccurring to him. "Unfortunately for me, and fortunately for you, I am all alone. But when my friends do find out what has happenedyou'd better look out. You'll be riddled so full of holes that thewind will sigh through your body as if it were a sieve. "

"How's Captain Billy?" demanded the man sharply. 

"Captain Billy?" wondered Ned. 

"Yes. You needn't pretend you don't know what I'm talking about. "

"I most certainly do not. Who is Captain Billy?"

"Know Joe Withem?"

"I do not. Some friend of yours, I suppose?"

An angry exclamation escaped the lips of the mountaineer. 

"I reckon they're no friends of mine. I reckon, too, that you'll beanswering my questions or you'll be hiking for the Happy HuntingGrounds in about ten minutes from now. I haven't got all night to sithere talking with you. I've got to git through with you; then I'mgoing to finish the rest of your crowd. You fellows thought you'd playa sharp trick on me, eh?"

"You are mistaken. We did not even know of your existence until youbegan shooting at us. Why did you do that?"

"If you don't know, I reckon you'll have to guess. Bill McKay mustthink we're easy down here, to try a game like that. "

"I'll tell him when I see him, " nodded Ned. 

"I reckon you won't see him right smart. When I git through with youI'm going to send a bullet through your head. Maybe they'll find youhere. If they do they'll know what it means, I reckon. "

Ned's face paled slightly. There was that in the eyes of the man beforehim which, all at once, told Ned Rector that the fellow meant whathe said. 

"Who do you think we are?" demanded the boy earnestly. 

"You're part of the Ranger gang. "

"The what?"

"The gang known as the Texas Rangers. "

Rector laughed. 

"You've got it wrong this time. We are not Texas Rangers. We areknown as the Pony Riders and we are out for our health and as good atime as we can have. "

"Ye can't fool me. That line of talk don't go down at all I'll tellyou what. Bill McKay thought to trap some folks by getting in a bunchthat wasn't known down in these parts. I had his little game sized upthe minute I set eyes on your bunch. But I'll clip your claws. I'llshow McKay that we ain't so easy. Now you out with the whole story. If you tell it straight, I may think about letting you go. If you lieit's the end of you. I'd as lief shoot you full of holes as I woulda yellow dog. Now what's your orders?"

"I haven't any orders, I tell you. "

"What did Bill McKay reckon you would do down here?"

"I don't know Bill McKay, I don't know any Texas Rangers, and if theyare anything like you and your kind, I don't want to know them. But Ido want to tell you that if you don't let me go---that if you heap anymore insults on me---it is you who will get a bullet through yourmiserable hide. I'm getting mad, Mr. Man. "

"Oho! Ye be, eh?"

"Yes, I am. "

"Then I reckon there's only one thing to do to put ye in a better frameof mind, " answered the mountaineer, shifting his rifle aboutsuggestively. "Now I'll give ye two minutes to open up and tell all yeknow, " was the stern announcement. 

In the meantime Tad Butler had not been idle. As the reader alreadyknows, Tad had been deceived as to the location of the shot. He hadgone a long distance out of his course. After a time he realized thisand at once started back toward the plain. It was his intention tomake the opening where they had first sought to make camp, as it wasthere or in that vicinity that he was to meet Ned Rector. 

The lad settled down to a trot. Every faculty was on the alert, forButler was a natural woodsman, added to which was an experience ofsome two or three years in mountain and on plain until Tad was familiarwith many of the tricks of the mountaineer. 

Suddenly the boy halted and stood with head thrown back sniffing theair. 

"Smoke!" breathed Tad. "There is a fire somewhere near here. Thatmeans some one is in camp here. I can't be far from the edge now. I must find out where the fire is. "

After a few moments of sniffing the lad decided that smoke lay offobliquely to the right of him. Having decided upon this he startedin the direction named, but proceeded with much more caution thanbefore as he did not wish to stumble upon strangers until he had firstdetermined whether they were friends or enemies. 

At last he saw a faint flicker of light. 

"It's there, " muttered the boy. "Now we'll see. I hope nothing hashappened to Ned. Still, he would have fired his revolver had he gotinto trouble. He may be waiting for me down by the creek. But I mustfind out what's going on here before I take time to look him up. Ihope the others don't come and blunder in. "

Tad paused in his reflections as the sound of voices reached his ears. Young Butler, crouching low, crept cautiously through the bushes, eachfoot being placed on the ground as softly as an animal stalking itsprey could have done. Not a sound did the young woodsman make. Ofcourse his progress was slow, but it was silent, which was much moreto be desired. 

Some fifteen minutes elapsed before Tad reached a point where he couldget a view of the fire. He was obliged to crawl some three or fourrods from that point ere he found a position where he could see themen who were near the fire. 

The first to attract Tad's attention was the mountaineer, squattingdown with head thrust forward, his rifle held across his chest, theman's hand over the trigger-frame. Butler knew that the first fingerof the right hand was toying with the trigger. His glances followedthe direction indicated by the muzzle of the weapon. Then Tad'sface flushed hot all over. There, back to a tree, a rope twistedtwice about his body sat Ned Rector, defiance in face and eyes. Nedwas looking straight at his captor. The situation was strained. ToTad, it was maddening. 

"What is it you want me to tell you?" demanded the prisoner. 

"I've told you that already. What are your orders?"

"And I have already told you, I have no orders from any one. "

"How many are in your party?"

"Five, not including the horses. "

"I wasn't asking about the cayuses. Who is in charge of you?"

"You wouldn't know if I told you. "

"I'm asking you!"

"His name is Zepplin, Professor Zepplin. "

"One of them scientific shooters, eh?"

"I don't know about his being a shooter. He is scientific, all right. But what's that got to do with you and me?"

"Did this---this perfesser get his orders from Bill McKay?"

"I should say not, " answered Ned with a mirthless laugh. 

"Who was it you was to look up?"

"I don't know what you mean. "

"Yes you do. Don't try to make a monkey of me. You'll be willing toanswer right smart after I've fanned you with a forty-four. Who is ityou and your bunch are after?"

"We are after no one. Can't you understand English?" replied Rectorwith some heat, "I have told you that we are here on a trip forpleasure and nothing else. "

"You said you was here for your health, a little time ago, " grinnedthe mountaineer. 

"Well, what if we are?" snorted Ned. 

"Nothing only that I'm going to drill you full of holes. The twominutes is about up. You've lied to me pretty near every word you'vesaid. You said you didn't know Bill McKay when I know you do. You'vesaid he hadn't given you any orders. You've---"

"You're crazy, " scoffed Rector. 

"I reckon if I am that you're more so if you think I am going to gulpdown all them fairy stories. You're young. Mebby you don't know thekind of a game you've stacked up against, but---"

"I ought to have some idea about it by this time, " returned Ned. "Everything you have said is a lie and you know it. I don't know you, nor do I want to, being somewhat particular about the people I know. And now once more, are you going to let me go?"

A sudden note of triumph had leaped into the tone of Ned Rector. Nedhad seen something that sent the blood coursing through his veinsmadly. That something was a figure that for a few seconds had beenoutlined in the faint light of the fire. 

The mountaineer caught the change of tone on the instant. Hissuspicions were aroused. His eyes narrowed. He slowly straightenedup until he had risen to his full height. Now the rifle came up toposition, ready for work. It was at his chest again. The mountaineerhad no need to bring the weapon to a level with his eyes. He couldshoot equally well from almost any position. 

Rector shot a quick glance over the mountaineer's shoulder. He couldnot resist one more look in Tad's direction. But that look was fatal. With a roar the fellow wheeled like a flash. 

Bang, bang!

The shots were fired with such suddenness that Ned did not realizethe fellow had turned until after the rifle had spit two charges offire and lead. Ned's head dropped. Everything grew black about himagain. The lad was in a fainting condition. It was all up with himnow. 

Ned had tried to cry out, but the words would not come. He could notutter a sound if his very life depended upon so doing. 

Ned found his voice at last. It rose in a mighty yell for help, a yellthat carried far beyond the spot where those exciting sceneswere being enacted. 

CHAPTER V

WHEN THE TABLES WERE TURNED

At the instant when Ned had shot his quick glance at the wondering Tad, the latter with quick instinct, realizing that Ned had made a seriousmistake, threw himself flat on the ground. 

That move undoubtedly saved Tad Butler's life. At least, two bulletswent ripping through the foliage over his head. The move served thefurther purpose of hiding him from the man who was shooting at him. The mountaineer had not even caught a sight of Butler, quick as hadbeen his turn about. The fellow swung to the right letting go twomore shots, evidently believing that he had not fired in the rightdirection. 

In Tad Butler's right hand was gripped a piece of rock that he hadgrabbed when he threw himself to the ground. The boy came to his feetas if propelled by a spring. At that second the eyes of themountaineer were fixed on a point several yards to the left of Tad. 

Without a sound Tad let go the rock. But the movement caught the eyesof the ruffian. He swung toward Butler at the same instant pullingthe trigger of his rifle. 

Once more the rifle roared its savage protest. But that was its lastroar for the time being. Almost at the instant when he pulled thetrigger the mountaineer received Tad's rock in the pit of his stomach. With such force had the missile been hurled that the fellow staggeredback, the rifle falling from his hands, both of which were suddenlyclasped over the part of his anatomy that had been struck. 

The fellow uttered a howl of pain. He swayed and staggered then fellover a dead limb, landing flat on his back with a crash. 

Tad, without an instant's hesitation, sprang forward. The eyes ofthe plucky Pony Rider Boy were flashing. Tad had not even thought todraw his revolver. But his anger was kindled. He was dangerous inhis present mood. He did not pause to think what a terrible chancehe was taking in thus rushing forward. Fortunately for Tad, however, the mountaineer was suffering such agonies that he either gave nothought to the revolver that was hanging at his side, or else he wastoo weak to draw it. He staggered to his feet, swaying, groaning, shoulders hunched forward, chin on his breast. 

Young Butler was upon him like a whirlwind. 

Whack!

Tad's fist caught the mountaineer squarely on the point of the jaw asthe man raised his head half defiantly, one hand groping awkwardly forhis pistol. 

The fellow went down in a heap. 

"Whoop!" howled Ned Rector. "That's the blow that put the finishingtouches to father. Cut me loose! Cut me loose! Quick, Tad! He'llbe up in a minute!"

Butler had no need to be told this. He knew the first thing to bedone was to secure the prisoner. Ned could wait. The danger laywith the man stretched out there on the ground. Tad worked rapidly. His rope was jerked free from his belt. Three swift turns were madeabout the body of the prostrate man, binding the fellow's arms firmlyto his sides. 

Next Tad jerked the mountaineer's revolver from its holster and cast itinto the bushes. Then he tied the man's ankles together, after whichhe straightened up and wiped the sweat from his face and forehead. 

"Whew! Warm, isn't it, Ned?"

"Rather, " drawled Rector. "Warmer for some folks than others. Itcame near being pretty warm for you. Are you going to cut me loose, or am I to stay tied to this tree for the rest of the night?"

"I guess we will let you up now. We shall have to wait until ourfriend there comes to his senses before going farther. Tell me howyou got into this mess. "

"The same way Chunky gets into trouble. I blundered into it. " Nedthen went on to relate briefly how he had been jumped on by themountaineer and made prisoner. 

"What was he trying to get you to tell him?"

"He accused me of being a Texas Ranger, a member of some fellow's band, a fellow named McKay. "

"The band or the man?" questioned Tad. 

"That was the man's name. Billy McKay. He's a captain of Rangers, orsomething of the sort, it doesn't matter much what. "

"I rather think it does, " answered Butler dryly. 

"How so?"

"Why, don't you see, it means that if the Texas Rangers are after thisfellow he must be wanted for something very serious. Who is he?"

"You may search me. Stacy may be right after all. There are plentyof Germans in Mexico, so why not some of them up here to stir uptrouble? He looks like pictures I have seen of some of those Hunassassins, " declared Ned Rector. 

"I think I will search him. He may have some more weapons about hisperson. "

Tad found a bowie knife in the mountaineer's boot, but that was theonly weapon left on his person. Tad threw the knife away. About thistime the prisoner began to show signs of returning consciousness. 

"You must have hit him an awful wallop, " wondered Ned, standing overthe man and eyeing him narrowly. 

"I did. I hit him first with a stone, then with my fist. I skinnedmy knuckles, too. "

Ned grunted. 

"I'd hate to have you land on me that way. That surely was asockdolager. He has his eyes open. "

"Oh, hullo!" greeted Butler. "We rather turned the tables on you, didn't we?"

"I'll kill you for this!" growled the prisoner hoarsely. 

"I don't think you will kill anybody to-night. What I would like toknow is what you mean by trying to shoot us up. "

"I'll shoot up the rest of you before I get through with you, you andyour whole gang. You can tell Bill McKay what I say and---"

"We don't know Bill McKay. We have nothing to do with any of youpeople down here. We are here for pleasure. "

"That's what the other cayuse said. Looks like you wuz, hey?"

"You alone are to blame for present conditions. We were not lookingfor you. You began shooting at us before we got into the foothills. Who were you shooting at the last time? I mean before you tried topot me just now. "

A growl was the only answer. 

"The question is, what are we going to do with this fellow, Tad?" askedNed. "Surely it won't be safe to let him go, and we can't leave himhere to starve to death. "

"No. I'll tell you what. We will fix up a litter---by the way, fellow, are there any more of your kind fooling about here?"

"You'll find out whether there are or not, " grunted the prisoner. 

"Thank you. You have answered my question. I now know you are alone. Ned, can you cut down a couple of saplings?"

"Where do you want to carry him?"

"Down to the fork. "

"Then let's drag him. Dragging is good enough for that ruffian---toogood for him. He ought to be shot, then rolled down the hill. "

"Don't be bloodthirsty. Prisoners of war should be treated with theutmost courtesy and consideration. I guess perhaps we had better nottake the time to make a litter. We can carry him down to the fork. Take hold of the feet. I'll take the heavier end. And you, fellow!You will get along much better if you keep quiet. Remember, no yellsnor struggles, else I shall be obliged to put you to sleep as I did ashort time since. Do you understand?"

There was no reply to the question. 

"All right. Pick him up, Ned, " directed Tad. 

"Are you going to take his rifle?"

"Yes, I guess perhaps it would be best. The rifle is good evidence, "decided Butler. 

Tad strapped the weapon to his own back. He did not bother to pick upthe revolver or the bowie knife. The rifle was the evidence that hewanted to take with him. Then they gathered their prisoner up. Heproved a heavy burden, though fortunately the distance was short tothe fork where Tad had decided to carry the man. The fellow hadnothing to say, but the expression in his eyes made up for what hislips did not utter. The two boys were glad enough when finally theyreached their destination and dropped their burden, though none toogently at that. 

"Now what?" demanded Ned. 

"I want you to hurry over to where the ponies are tethered, then rideto the outfit. Tell them to pack up and move over here at once. "

"Give me a signal before you come into the gulch here. I'll answer itif all is right. Then you may come in without fear. "

"What are you going to do?"

"I am going to stay here to keep our friend company. He might getlonesome if we were to leave him alone, " chuckled Tad. "Get back assoon as you can. I'll have a fire built, then we'll get supper. Didyou know this fellow took another shot at Chunky?"

"No. Was that what he shot at?"

"That was it. "

"I hope he didn't hit him. "

"I guess not. "

"Chunky seems to be getting more than his share of lead to-day, "answered Rector with a chuckle. "Serves him right. It'll teach himto be more prudent. "

"I don't think you are exactly in the position to say much yourself, "replied Tad, his eyes twinkling mischievously. 

Ned flushed to the roots of his hair. 

"For goodness' sake, don't tell the crowd how I got jumped on. I am aseasy as a baby. I'll never call myself a mountaineer again. "

"Never mind. You showed your grit at any rate. You didn't appear tobe the least bit scared. "

"I wasn't. But honest, Tad, now that I've had time to think it allover, I'm scared stiff right this minute. I believe he would haveshot me. "

"There is no doubt of it in my mind. So he thinks we are Rangers?"

"Who are the Rangers, anyway?"

"The Rangers are a body of men who did much toward clearing this stateof the bad men that infested it for a long time. "

"They don't seem to have got them all, " replied Rector. 

"No, there are some near the border still. The Rangers are a sort ofpolice who range over the state wherever their services may be needed. I understand they are paid by the state. I guess there are not manyof them left. The necessity for Rangers is not what it was a fewyears ago. "

"So I should judge from what has just happened, " answered Ned somewhatironically. 

"Come, are you going to get started tonight?" demanded Tad with a laugh. 

"I'm off this very minute. "

Ned hurried away laughing. He bore evidences of his recent encounterwith the mountaineer, but all this was forgotten now that the man hadbeen taken and was safely tied up back there in the canyon with theever vigilant Tad Butler on guard over him. 

A short time after that Ned was riding his pony over the plain towardthe camp at a fast gallop. He shouted as he neared the camp, whereno fire had been lighted, uttering a subdued whoop as he rode in. Chunky and the professor met him a few rods from the camp. 

"I---I got shot again!" cried Chunky. 

"Where is Tad?" called the professor. 

"Over on the fork waiting for us. You are to pack up and return withme at once. "

"But---but, the danger, " protested Professor Zepplin. 

"The danger is past. I don't believe you will have to worry. "

"Explain what you mean!"

"I'll leave that for Tad to do after we get over there. Are youall ready?"

"Is Tad all right?" demanded Perkins. 

"Fit as a fiddle. You can't put Tad out of business for any lengthof time. You are to fetch everything. We are going into camp wherewe originally planned to spend the night, " advised Rector. 

The professor, very much relieved to learn that the boys had met withno harm, but still somewhat nervous from the hours of fretting he hadpassed when the lads failed to return, now hastened to get ready toaccompany Ned. On the way he explained bow Stacy Brown had beenfanned by another bullet when the fat boy indiscreetly showed himselfon the rise of ground between the camping place and the foothills ofthe mountains. 

"Maybe you'll learn something one of these days, " scoffed Ned. 

"I---I've learned something to-day. "

"Have you?"

"I have. "

"Well, what have you learned?"

"That these fellows down here can shoot to beat the band. "

"I have observed something of the same sort myself, " muttered Ned, withthe memory of the mountaineer's bombardment of Tad Butler. 

The party had set out at a slow trot with Ned leading the way. Ned'sconfidence assured them that all was as it should be, but the youngman turned a deaf ear to all their questions, replying only now andthen with the remark that Tad would tell them all that was to be toldwhen they got to the camping place. 

In the meantime Tad had built up a fire, mainly for the reason that hewanted to keep his prisoner well in sight all the time. Butler knewthat the man was a tough customer and that were he to get free itwould be a sad night for Tad Butler, and so, too, perhaps, for therest of the party. 

The prisoner had nothing to say, nor did Butler seek to draw the fellowinto conversation. But the man was watching every move of the youngrider who had so cleverly outwitted and captured him. The mountaineernow believed more firmly than before that these two young men werecarrying out the orders of Captain Billy McKay of the Texas Rangers. He swore to be revenged on every man of them when once he had gainedhis freedom. At present that hour of revenge was a long way off. 

Suddenly a loud "Yip! Yip! Yahee!" sounded off on the plain. Tadsmiled broadly. 

"That's Stacy Brown, I'll wager my hat. I'll bet Ned is scolding him, too. "

Ned was. He was at that instant threatening to break Chunky's headif he opened his mouth again before they reached the camping place. Shortly after that Butler's keen ears caught the sound of hoofbeats. He stepped back into the shadows, the prisoner eyeing him inquiringly. Tad did not take the trouble to explain. Let the prisoner think whathe might. Then the party rode in in single file. Tad was not in sight. He was hiding in the bushes. 

Professor Zepplin pulled up short when his glances finally came to reston the bound form of the mountaineer; Stacy Brown's eyes grew largeand Walter Perkins gasped. 

CHAPTER VI

THE CAMP IN AN UPROAR

"Tad! Where is Tad? What does this mean?" demanded the professor. 

"Hullo, boys, " cried Butler stepping out into the light. "Did youthink that was myself tied up there?"

Chunky, in the excitement of the moment, forgot to tell Tad that hehad stopped another bullet out on the plain. 

"What do you think of our prisoner, Professor?"

"Tad, will you be good enough to explain what this means?"

"Yes, sir. To be brief that's the fellow who shot at us. He tried tokill us both up here in the mountains. "

"Are you sure?"

"Positive. "

"I guess I ought to know, " grinned Rector, "He jumped me, tied me toa tree, then was about to blow my head off when Tad appeared just intime to save my precious life. "

By this time Stacy had slipped from his saddle and striding over tothe prisoner stood looking down at him. "So, you're the fellow whopotted me twice to-day, are you?" demanded the fat boy sternly. Theprisoner made no reply, but he gazed up at his tormentor so savagelythat Stacy instinctively took a step backward. 

"He is the man, but we landed him, " answered Rector proudly. 

"Is there any objection to my giving the ruffian a good hard kick forluck?" asked Stacy. 

"There certainly is objection to your doing anything of the sort, "returned Tad sharply. "We have not come to the point where we treatour prisoners of war the way the Germans do theirs. You let the manalone or I'll have something to say to you. "

"Stacy!" rebuked Professor Zepplin sternly. 

"Yes, sir?"

"You will keep away from the prisoner. Tad, I want to hear all aboutthis. "

"There is not much to tell, except that we got him, though he nearlygot us. He caught Ned napping. I should have fallen just the samehad I been in Ned's place, for this fellow is a bad man. Ned has toldyou what happened to him, else I shouldn't have said anything aboutthat part of the affair. While Ned was trying to find where the shotcame from that caught Stacy last, this fellow spotted and captured him. I was hunting for the source of the shot at the same time, but wentastray. I was finally attracted by the smell of smoke. I arrived onthe scene about the time that fellow was getting ready to take Ned'slife. At least, that was the way it seemed to me. "

"Yes, he was, " interjected Rector. 

"You were an easy mark!" jeered Stacy. 

"At least I didn't stop two bullets, " answered Ned witheringly. 

"The fellow caught Ned looking at me and knowing instantly thatsomething was wrong he whirled and shot at me. He missed, then Ishied a stone into his solar plexus, " said Tad. 

"That sounds like astronomy, " ventured Stacy. 

"You're wrong; it's geography, " chuckled Rector. "I'll finish thestory. The ruffian fired twice more after the first two shots at Tad;then he went down as the stone landed on him. By the time he had gotup, Tad was on the job and punched him in the jaw. "

"Boys, boys!" rebuked Professor Zepplin. "One would think this was aprize fight you were describing. "

"It's the truth, " protested Ned. 

"Of course it is, " laughed Tad. 

"That may be. But be good enough to moderate your language. You candescribe the scene without using questionable language. "

"Yes, it's disgraceful, " added Stacy, whereat Ned gave the fat boyanother withering look. 

"As I was about to say, " continued Rector, "this gentleman of themountains had got to his feet when Tad gently smote said gentlemanon the tender part of his chin. The gentleman fell down and went tosleep like a little child after a full meal. When the gentleman wokeup we had him hog-tied---"

"During which time our friend Ned remained tied to a tree, " chuckledButler. 

"Pshaw! I thought so, " grunted Stacy. "Brave man is Ned Rector! Ifyou were a scarred veteran like myself then you'd have a right to swellout your chest, " added the fat boy, gingerly stroking the bullet markon his cheek. "Well, go on. We're listening. "

"That's all there is to tell, Professor, except that we carried theman down here and there he is. "

Professor Zepplin stroked his bristling whiskers reflectively. 

"What is your name, my man?" he asked stepping up to the prisoner. But the fellow made no reply. 

"I said what is your name?" repeated Professor Zepplin. 

"What's that to you, old Whiskers?"

The professor started, a faint touch of color showing under his tan, while audible chuckles might have been heard from the boys in thebackground. 

"Such language will not help you. What is your name?"

"Yours will be Mud when I git out of this, you old scarecrow! Don'tyou stand there jawing over me. I don't like it, " added the prisoner, so savagely that the professor shrank back a little. 

"It's no use to question him, professor, " spoke up Tad. "He won'tanswer questions. "

"I question our right to hold him, " said Professor Zepplin. "We haveno proof that he is the man who shot at us. "

"I've got proof that he assaulted me, " bristled Ned. 

"And I that he shot at me four times, " added Tad. "I should thinkthat were proof enough. What would you do, Professor?"

"I was thinking that we should let the man go with an admonition. "

"No, no, no, " protested Chunky. "I don't want to be shot up againto-day. "

"Don't be afraid, little boy, " urged Rector. "We are not going to letthe man go---not if I have to fight for it. "

"Professor, this fellow thought us Rangers, " began Tad. 

"Rangers?"

"Yes. He admitted in his questioning of Ned that he thought we wereRangers, or that we had been employed by the Rangers to run him down. That is why he sought to kill us. "

"But surely you assured him we were not, " protested Professor Zepplin. 

"Little stock did he take in our assurances, " scoffed Ned. "You mightas well talk to the wind. "

"But what are we going to do with him, boys?"

"I have thought of that, " replied Tad. "It is my idea that he is abad man. He must be, else the Rangers would not be looking for him. He has proved that he is a dangerous customer to be at large---"

"Yes, he's large, all right, " mumbled Stacy. "As I was saying, itseems to me to be our duty to turn him over to the officers of the law. "

"Where?"

"I don't know. Is there any town near here?"

"Some twenty miles to the southeast, I believe, " answered the professor. 

"Then that is where we must take him. "

"We may find, then, that we have made a mistake, " objected the professor, still doubtful about the wisdom of the course proposed by Tad Butler. 

"Then we will make a complaint against him ourselves, " answered Tadfirmly. "I don't propose to let him off after what he has done. Why, were we to let that man go our lives wouldn't be worth a cent. Hewould shoot us before the night was over. No, Professor, he must beheld prisoner until we can get him to town. "

"But we can't go on to-night. "

"No. The morning will be time enough. We will give him some food. "

"Let me feed the animal, " urged Stacy. 

"You have steady business performing that office for yourself, "retorted Ned Rector. 

"In the morning we will take him to town. Shall we get some supper now?"

"Yes. I will think over your proposal in the meantime. Stacy, youmight gather some more wood for the fire. Ahem! This has been a mostremarkable proceeding all the way through. "

"You would have thought so if that fellow had jumped on you as he didon me, " growled Ned Rector. "I thought the mountain had fallen downon me. He is bad medicine. "

Tad by this time was getting out the things for supper. They were latewith this meal owing to circumstances over which they had not had fullcontrol, though matters were now pretty well in the hands of the PonyRider Boys. 

"You had better tell us who and what you are. You have heard whathas been said here, my man, " said the professor returning to theprisoner. 

"I reckon I've heard enough. I reckon, too, that you've made a mistake. I ain't what you think. I'll tell you, now that the fresh youngfeller isn't listening. "

"Do so, " urged Professor Zepplin, preparing to listen. 

"Lean over so the others won't hear. "

"Surely. "

"You're a right smart old party and I don't mind talking to you, foryou've got right smart sense and you'll understand what I'm getting at. "

"Say what you have to say, my man. I am listening. "

"Between you and me I'm an officer. I'm looking for some parties thathave been cutting up didoes down in these parts of late. When I sawyour party I thought you were the lawbreakers, so I up and let go. I saw that there were too many for me and it was the only chance Ihad to---"

"But surely you didn't have to kill us. "

"I didn't kill you, did I?"

"True; true. "

"I was telling you, I thought you were they and I let go a few shots, just as a tickler. You see, I could have picked you off one at a timejust as easy as eating pie. I'm a dead shot, I am. "

"Then you only sought to drive us off?" questioned the professor. 

"Yes, that's it. You're a wise old party. They're a bad lot, you know. "

"But what about this assault on my boys?" demanded the professor. 

"Same thing. I thought they were them. "

"Your grammar is shocking, my man, but what you say is deserving ofcareful consideration. You say you took us to be bad men?"

"Sure I did. "

"Who did you think we were?"

"Tuck O'Connor and his crowd. "

"Who are they?"

"Well, you see, they do some smuggling over the Rio Grande. Thenagain, they are up to a few other tricks that the public hasn't goton to yet. What I want to do is to get away from here, quiet-like, so the youngsters won't get wise in time to cut up. Of course I ain'tafraid of them. I don't want to hurt them, you see. "

"I see, " observed the professor dryly. 

"I've got to get away to-night. If I'm held till morning I'll have totake you all in. You'll all have to go back with me to State Lineand you'll be locked up for interfering with an officer. "

"How comes it that you feared we were Rangers then, if this be true?"

"Aw, I was jest bluffing. I wanted the youngsters to give theirselvesaway, you see. "

"I see, " reflected the professor. 

"Then you'll let me out?"

"I am afraid I can't do that. "

"Then lean over here and I'll tell you a secret that'll make you changeyour mind. "

The professor leaned closer. The man's hands, free from the wrists, were moving cautiously. All at once Professor Zepplin's revolver wassnipped from its holster and a bullet tore through his clothes, takingsome of the professor's skin with it. The professor fell back, staggering to one side out of range where he sank down to the groundholding a hand to his side. 

CHAPTER VII

RECEIVING A LATE VISITOR

So unexpected had been the shot that, for a few seconds, the boys stooddumbfounded. 

"I'm shot! I'm shot!" yelled the professor. 

Bang!

A bullet whistled close to the head of Tad Butler. Stacy Brown, whowas just coming into camp with an armful of dry wood for the campfire, dropped his burden and with a howl made for shelter. Tad and Ned hadsprung to one side so as to be out of range, while Walter Perkins hadflattened himself on the ground. 

"Lie still!" commanded Tad sternly as the professor started to get upfrom where he had sunk down. "Are you much hurt?"

"I---I don't know. "

"Drop that pistol, you!" commanded Tad, glowering at the prisoner. 

The man laughed. 

"I've got you children now, " he sneered. "I'll pick you off unless youdo as I tell you. Now you come over here. Walk straight, one handout. Leave your guns behind. Cut me loose or you're a dead one, "commanded the prisoner. 

"Oh, am I?"

Tad glanced around to make sure that all the boys were out of range. Then with a quick leap he got entirely out of range of the revolverin the hands of the prisoner. Tad had thought he was out of rangebefore, but the man on the ground had twisted the weapon about untilits muzzle was pointing in Butler's direction. 

But this time the lad got out of range without question. But he wasno better off than before. Reaching for his revolver he made thediscovery that he had thrown off his belt with revolver and cartridgesbefore beginning to get supper. The others were in no better shape. Not a boy had his revolver on, and the professor's weapon was in thehands of the prisoner. 

"I know a trick. I've played it once to-day and I can play it again, "declared Tad, searching for a stone, while the others got well out ofthe way, watching T. Butler. In an emergency they always looked tohim to get them out of their difficulties. 

"Professor, you lie still. Don't move. I'll fix this fellow. Youhad better get a good bit farther off, " advised the lad, observing amovement on the part of the mountaineer. 

Suddenly the latter braced his head and digging his heels into theground ran around, pivoting on his head. Tad anticipated the movementby running a few seconds in advance. For a few moments it was a raceof wits. The lad as yet had not found a stone suited to his immediaterequirements. He was using his eyes in this direction as well aswatching the prisoner. Once the latter tried a shot at the boy. Thebullet passed Butler rather too close for comfort, but the Pony RiderBoy appeared not to have heard the shot. 

Not a word was being said by the lad's companions. The professor laywhere he had fallen, the perspiration streaming from his face and bodyup the side of the canyon the big eyes of Chunky might have been seenpeering through between the bushes at the exciting scene below. Allat once Tad stooped over. When he straightened up with a bound thatcarried him several feet to one side, he held a good-sized stone inhis right hand. 

"Now will you drop that pistol?" demanded the Pony Rider Boy. 

"I'll drop you!" roared the enraged enemy. 

No sooner had he uttered the words than Tad, with a well-directed toss, dropped the stone fairly on the stomach of the man on the ground. 

The prisoner uttered a yell that might have been heard a quarter of amile away. Ere the yell had died out another stone landed nearly inthe same place. The weapon dropped from the hands of the fellow, falling between his legs where he could not reach it without changinghis position materially. This he tried to do in a series of quicktwists and wriggles, though the boys knew from the expression on hisface that he was suffering great pain. It was not surprising, in viewof the fact that two rocks, each weighing from eight to ten pounds, had been dropped on his stomach. 

The fellow found no opportunity to recover the lost weapon. Tad wasupon him with a rush. Grabbing the mountaineer's feet he dragged theman roughly to one side. 

"I guess that will be about all for you, my man. You may push us toofar. I shan't promise to let you off so easily if you try any moretricks. Professor, are you much hurt?"

"I---I don't know. I'm bleeding. "

"Let's see what he did to you. "

A quick examination developed the fact that the professor had sustainedmerely a flesh wound. It was bleeding very little now. Tad, at theprofessor's direction, washed and dressed the wound, binding a pieceof cloth firmly about the waist. 

"There, I guess you will be all right now. You may come down, Chunky. The fun is all over for the present. How did he happen to get youthat way, Professor?"

Professor Zepplin explained how the prisoner had tricked him, declaringhis belief in Tad Butler's statement that the prisoner was a bad man. The professor no longer urged the release of their prisoner. Tadsmiled mirthlessly. Perhaps it was better that the professor shouldhave had an object lesson. He would take no further chances with thefellow after that. As for the prisoner, he was fairly frothing at themouth with rage. 

Now that the excitement had come to an end for the moment Stacy Brownwent about his task of gathering more wood for the fire. This timehe went quite a distance down the canyon, carrying a torch that hemight the better find that for which he was in search. 

Stacy was busy gathering wood, muttering to himself as was his habit, when all of a sudden he straightened up, conscious that some one wasstanding beside him. As he rose the fat boy's nose nearly bumped intothe muzzle of a revolver. The revolver was backed by a not unpleasant, but stern face. 

"Wha---wha-----what---" stammered the fat boy. "Wh---wh---who---"

"Not a sound, young man, if you value your life. Who and what are you?"

"I---I'm a Pu---Pu---Pony Rider Boy. "

"A what?"

"A Pu---Pony Rider Boy. "

"What are you doing here?"

"Ga---gathering firewood. "

"Who is your party?"

"Pro---professor Ze---Zep---Zepplin and the boys, " stammered the fatboy, trembling at the knees. "I haven't done anything, but I'm abu---bu---bad man when I get ma---mad. "

The stern-faced stranger grinned appreciatively. 

"You are not the fellows who came in at State Line the other day, are you?"

"Ye---yes, we're the bu---bu---bunch. "

"Oh, fudge!" groaned the stranger. "And to think I've been to all thistrouble to round up a bunch of tenderfeet. " The man thrust hisrevolver into its holster with a grunt of disgust. 

"I'm Withem, " he snapped. 

"So am I, " answered Chunky. 

"I said, 'I'm Withem, '" repeated the stranger. 

"I said I was too, " reiterated the fat boy. 

"Look here, what are you trying to get at, young man?" demanded thenewcomer with a slight show of irritation. "Are you trying to makesport of me?"

"N---n----no. You said you were with them---with us---with the crowd, you know. And I said I was too. "

The stranger tilted back his head and laughed softly. 

"You little cayuse, my name is Withem. W---I---T---H---E----M!" hespelled. 

"Oh!"

A broad smile grew on the face of the Pony Rider Boy as he asked:

"What do you reckon you want here?"

"I'm just looking around a bit. I think I'll go to your camp with you. "

Stacy surveyed his companion critically from head to foot. 

"All right, " he said. "If you want to take the chance, I'm willing. "

"What chance?" demanded the stranger. 

"Tad Butler might take it into his head to throw you out, or something, if he doesn't like your looks. "

"I'll take the chance. "

"All right; come on. But mind you, it'll be the worse for you if you tryto start anything. We're a bad lot, we are, and don't you forget it. "

A moment or so later the Pony Rider Boys were amazed to see Stacystrutting in with a stranger in tow. 

"He's with us fellows, " was the fat boy's announcement. 

"Withem's my name, " corrected the stranger. 

"Yes, he's with 'em. But he hasn't said who it is he is with. Ithought I was with him when he shoved a pistol under my nose. "

"Good evening, sir, " said Tad stepping up, directing a quick, keenglance of inquiry into the eyes of the newcomer. In that one glanceButler decided that the man was all right. It was a relief to see aface like that after their experience with the mountaineer. 

As for the prisoner himself, who lay back in a shadow now, he startedviolently the instant he beheld the man who had just come into thecamp of the Pony Rider Boys. The prisoner looked as if he had a severecase of ague for he fairly shrank within himself. 

"You are just in time to join us for a bite, Mr. Withem. That is yourname, is it not?"

"That's my name. "

"Mine is Tad Butler. This is Professor Zepplin. The young man withwhom you came in is Stacy Brown, otherwise Chunky, and here are Mr. Rector and Mr. Perkins. If you will gather around the fire I'll servethe chuck. "

"Thanks, young man. You certainly know how to do the honors, as wellas how to fry bacon. I could smell that across a county and I'd rideto it as fast as horseflesh could carry me. "

"Are you from these parts?" asked the professor after they had seatedthemselves on the ground. 

"Yes, I'm from everywhere, " laughed Withem. "By the way, young man, that looks like the mark of a bullet on your cheek, " he continued, bending a keen glance on Stacy. 

"Then it looks like what it is, " muttered the fat boy. 

"I don't want to be inquisitive, but---"

"No, it isn't considered good manners to be too curious down in thiscountry, I've heard. "

"Right you are, yonnker, " laughed Withem, in which the others joinedheartily. "Men have been known to get into trouble by being toocurious, especially down on the Rio Grande. The-----"

The visitor's conversation was interrupted by something falling overfrom beside the tree against which he was sitting. That somethingwas the rifle the boys had taken from the prisoner. 

Withem picked up the gun with the purpose of replacing it. He wasjust standing it against the tree when suddenly he stopped, bringingthe gun around in front of him where he could get a better view of it. 

The Pony Rider Boys were regarding him questioningly, Tad almostsuspiciously. Chunky was wondering if their visitor was going toshoot. The fat boy was ready to run at the first sign of trouble. He had stopped enough bullets for one day. As for the prisoner, hisbloodshot eyes were taking in every movement of the man Withem. 

"You seem to be much interested, " suggested Tad. 

Withem flashed a keen, searching look into Butler's face. 

"I am. "

"Why that's-----" began Walter, then subsided at a warning look from Tad. 

"Pardon me, but will you be good enough to tell me where you gotthis rifle? I have good and sufficient reasons for asking thequestion, " said Withem almost sternly. 

"We took it from a man who had set out to shoot us up, sir, " repliedButler. 

"Tried to shoot you up? When? Where?" demanded the visitor with atrace of excitement in his tone. 

"This afternoon and to-night. Stacy Brown's cheek bears evidence ofthe fellow's marksmanship. It seems the man took us to beofficers---Rangers, he said. "

"Then you---you talked with him?"

"We did, " answered Tad with a twinkle in his eyes. "In fact we heldquite a lengthy conversation with the gentleman. "

"Explain what you are getting at. " Withem was deeply interested in thescant information that had been given to him. They saw that he wascontaining himself with difficulty. 

"Tell, Mr. Withem. Don't beat about the bush, " advised the professor. 

"Yes; tell me what became of the fellow who shot you up, " urged thevisitor. 

"What became of him, sir?"

"Yes, yes!"

"Why we caught and made him prisoner. "

"What!"

"Yes, sir, and we have him now, " smiled Tad Butler. 

"You've got him now? Where is he?" roared the visitor springing tohis feet, permitting the captured weapon to fall to the ground. 

"He is over there in the bushes, " said Tad. "However, I think youhad better wait until I get over there before you pay him a visit. I have a sort of proprietary interest in that fellow and I don'tpropose to have any monkey business. He nearly killed ProfessorZepplin, bound though he is. Wait one moment, please. Why do youwish to see the man?"

"Because I think I know him. Gentlemen, I am a Ranger. I am LieutenantJoe Withem, and I have good reasons to believe your prisoner is a manwhom I have been anxious to meet for some time. I am ready to be shown. "

Tad wonderingly led the way over to their captive, the lieutenantfollowing in quick, nervous strides, the others of the party bringingup the rear, Chunky lugging a rifle which he kept in position forinstant use in case the stranger should seek to liberate their prisoner. But there was little danger of Lieutenant Joe Withem doing anythingof the sort, CHAPTER VIII

A MUCH-WANTED DESPERADO

Tad had snatched a burning brand from the fire, carrying it along withhim so that Withem might get a good look at the prisoner. The ladconsidered it a fortunate coincidence that the Ranger lieutenant shouldhave visited their camp at that particular time. 

The instant Withem set eyes on the prisoner he uttered an exclamationunder his breath, while the prisoner glared up at him with menacing eyes. 

"Hullo, Dunk, " greeted the Ranger. "You seem to be in limbo. I reckonyou bit off more'n you could chew, for once in your life. Thought youwere shooting up Rangers, did you? Instead you barked up againstsome tenderfeet who were too much for you. I guess you ain't quiteso smart as you thought you were. "

"I reckon you've made a mistake, " growled the prisoner. "I don't knowwhat you're chewing about. "

"That's all right, Dunk. I don't reckon it makes any difference whatyou think about it. We've got you hard and fast, and you're done for. I reckon, too, that the captain will be glad to see you. He'll have awarm welcome for you, you bet. They certainly have you tied up forkeeps, " laughed the lieutenant, bending over to examine the prisoner'sbonds. "They certainly have. Come on, let's finish that bacon, " addedthe Ranger straightening up. 

The party took its way back to the campfire, Stacy disgustedly throwinghis gun on the ground at the foot of the tree where lay the prisoner'srifle. 

"Now, sir, perhaps you will explain who and what this man is? Youappear to be well acquainted with him, " said the professor. 

"I am that. But how did you get him?"

"Master Tad there will answer that question. He and Rector made thecapture. "

"You two younkers caught that man?" wondered the lieutenant. 

"Yes, sir, " replied Tad modestly. "But I'll admit that it was apretty tough job. He nearly got us. "

"Tell me about it. "

Tad did so briefly, making as little of his own achievement as possible. He related also, how the prisoner had gained possession of ProfessorZepplin's revolver and of the latter's narrow escape from death. 

"Boys, you've done a big thing. The captain will be interested inyou, " said Mr. Withem. "He's been wanting this man for a long time. "

"You haven't told us who the fellow is, yet, " reminded ProfessorZepplin. 

"He is Dunk Tucker, sir, one of the most dangerous customers infestingthe border. We have been on his trail for weeks, but he's managed togive us the slip every time. We never expected to capture him alive. We expected to have to shoot him on sight, which we probably wouldhave done. "

"Is it possible?" murmured the professor. "I did not suppose suchconditions existed on the border at this late day. "

"They do not, ordinarily. "

"What has the man Tucker done?"

"Done? It would be easier to tell you what he hasn't done. He'scommitted pretty nearly every crime in the calendar and some thataren't in the almanac. He is one of a band of thieves that has beenoperating on the border for months. They are smugglers and thieves. They have even gone back to the old style of stock stealing. Up todate it is estimated that they have run across the border into Mexicoseveral hundred head of stock. The ranchers are up in arms. TheRangers have been called in to put the Border Bandits out of business. This is the first one of the gang that we have captured. And, afterall, we didn't capture him. That was left for a bunch of pluckyyoung tenderfeet---two of them, to be exact. 

"Furthermore, it is suspected that Dunk and some of the other bad menof his crowd are in the pay of German agents in Mexico. The Germansare trying to stir up trouble on this side of the line, and theseborder ruffians are ready to do anything for the sake of easy money, even at the expense of being traitors to their country. It isbelieved that German money is finding its way into their pockets. The hounds!" raged the Ranger. 

"Surely these men have not resorted to force---committed murder oranything of that sort?" interposed the professor. 

"Not that we know of, though some of them did have a pitched battlewith a rancher over on the western border of the state. A few stoppedbullets, but so far as we know no one was killed. I am telling youall this in confidence. There are a good many in this thing whosenames we do not know. "

"You can make the prisoner confess, can you not?" asked ProfessorZepplin. 

"Confess?" the lieutenant laughed. "You don't know these BorderBandits. No, they never confess. There will always be more or lesstrouble down on the Rio Grande. It is so close to Mexico, so easy toget across the border that bad men cannot resist taking advantage ofit. That is why the Rangers are still in business. If it were notfor the border we all should be looking for other jobs. As it isthere aren't many of us left. "

"How many?" asked the professor. 

"Some thirty in the state, that is all. We are subject to the ordersof the governor, though we're left pretty much to ourselves. "

"Who is your commander?"

"Captain Billy McKay. "

"That's the man Dunk named. He accused us of belonging to McKay's bandof Rangers, " said Rector. 

"He did, eh?"

"Yes. "

"I thought so. Still, he might have shot you up just the same, even ifhe had known you hadn't anything to do with us. "

"Where is the rest of your party, Mr. Withem?" asked Tad. 

"They're out on the trail, " was the somewhat evasive answer. "I'llget in touch with them sometime to-night or to-morrow. "

"But you will take Tucker with you, will you not?" asked Ned. 

"I reckon I will, " laughed the Ranger. 

"Shall we take him along for you? You have no horse?" asked Tad. 

"My nag isn't far from here, " smiled the lieutenant. "I'll load himon like a sack of meal. He'll get a good shaking up, but it won'thurt Dunk. He's too tough to be bothered by a little thing like that. We'll land him in the calaboose in El Paso by the day after to-morrow. Where are you folks going?"

"We planned to do the Guadalupes, then go on down to the Rio Grande, "answered Professor Zepplin. 

Withem reflected. 

"I reckon the captain will be wanting to see you. There's a rewardout for Dunk. Captain Bill is on the square. He'll 'divvy' with youfairly. "

"We are not looking for any rewards, " spoke up Tad quickly. "You maytell him that whatever reward is paid, belongs to the Rangers. We areglad to have served you, but remember, we did so to save our own skins. "

Withem extended his hand, grasping Tad's hand within it. 

"You're the right sort, young man. I wish we had you with us. "

"In the Rangers?"

"Yes, of course. "

"I am afraid that would not be possible, " smiled the Pony Rider Boy. 

"Wholly impossible, " affirmed Professor Zepplin with emphasis. 

"I suppose so. However, I want you to see the captain. I'll tellyou what to do. " The lieutenant lowered his voice. "We will be incamp to-morrow night about twenty-five miles to the southwest of here. Know where Doble's Spring is?"

"No, sir. "

"You can find it. The water gushes out of the rocks pretty high up, falling in a sort of spray. You can't miss the place. You'll hear itif it's after dark when you get there. "

"And, further, you'll probably see a campfire, but sing out before youcome in too close. Some of our boys are rather sudden when they'reinterrupted at night, " grinned the Ranger. 

"I should call it violent, " declared Stacy. "The way you poked thatpistol in my face back there was a caution. You nearly scared me outof a week's growth. "

No one paid any attention to Chunky's interruption. 

"Will your captain be there?" asked the professor. 

"I reckon he will But I can't tell for sure. McKay is a pretty busyman. You don't know where to find him. He may be here to-night. And to-morrow morning he may be sixty or seventy miles away. Youcan't tell about Billy McKay. "

"Is there any danger of our having difficulties with any of thisfellow's companions?" asked the professor apprehensively. 

"I reckon not. At least there won't be after you have come up withour party. We'll see to that. "

"Where are their headquarters---in these mountains?" questioned Tad. 

"We don't know. That's what we're trying to find out. We havereckoned they had their hang-out here, but we haven't found it yet"

"How many are in this band of Border Bandits?" asked Butler. 

"There are some that we don't know. We do know a few of them, however. For instance, there's the Mexican, Espinoso, known as the 'Yellow Kid. 'Then there's Greg. Gonzales, a half-breed Mex bandit, and Willie Jones. "

"Willie Jones! That's a funny name, " laughed Stacy. "That doesn'tsound very savage. I shouldn't be afraid of a fellow with a namelike that. "

"You would if you knew him. Willie is a dude. He dresses like a cityfellow with all the frills he can pile on, and he has the manners ofa city chap too. But you look out for Willie. There isn't a colderblooded man in the state than Willie Jones. He's quick as lightningon the gun and can hit a bull's-eye with his own eyes shut. "

"If he is any worse than our prisoner over there, I don't think I careto make his acquaintance, " replied Butler with a laugh. 

"He is, young man. You'd know Dunk to be a bad man the first timeyou saw him. You wouldn't think it of Willie and by the time you gethim sized up, it's too late to do you any good. I hope you don't meetwith Willie and try to land him. If you do you'll be carried out ona litter, reduced to a pulp. "

"Br---r----r---r!" shivered Chunky. 

"Where---where is this bad man supposed to hide himself?" asked theprofessor. 

"I wish I knew, " sighed the Ranger. "It would be worth a cold thousanddollars to me and perhaps some more. There's a price on Willie's head. But what's the use speculating about it? We'll get him some day, buthe'll be a dead one when we do. I'd a sight rather capture him alive. "

The boys listened to all this with deep interest. They had nevercome in contact with such cold-blooded discussion over human lives. They began to understand something of the things they had readconcerning conditions in the Lone Star State in the early days whenmen's passions ran riot; when practically the only law of the landwas the law of the gun. Now, conditions had changed. It was onlyin certain localities that lawlessness reigned in Texas, but thesewere bad spots, as evidenced by the presence of the Rangers, thatintrepid body of men that for thirty years had been the terror ofevildoers. The Rangers were pitted against a worthy foe in thisinstance, though it was a certainty that in time the Rangers wouldget their men, either dead or alive. 

"And now I reckon I'll be going, " decided the lieutenant, after havingpartaken heartily of the appetizing meal. "I'll be expecting you atthe Spring when we get there to-morrow. "

"Thank you; we will endeavor to be there. It will be a pleasure tomeet your commander. We may get some useful advice from him. "

"We'll bring up your horse if you will tell us where he is, " offeredTad. 

"Thanks, pard. He's on the other side of the creek about fifteen rodsfrom here. "

Accompanied by Ned, Tad hurried down, but found some difficulty inlocating the horse, so carefully had the animal been secreted. Withemsmiled when he saw them coming back. 

"I guess you boys are all right, " he nodded. 

They helped him load the prisoner over the horse's back, after which, giving each of the party a cordial shake of the hand, LieutenantWithem rode away. They observed that his rifle was resting across thebody of the prisoner, as if the lieutenant were looking for trouble. The trouble came sooner than they expected. The Ranger had been goneless than twenty minutes when a volley of rifle shots crashed out. 

"He's attacked!" cried Tad. 

"Quick! Put out the fire!" shouted the professor. 

"Don't wait for the fire. We must go to his assistance!" answeredTad, snatching up his rifle and making a bolt for his pony. "Comeon, boys, we've got something to do this time. "

"Stop!" commanded the professor. 

"What, sit here while a band of bandits are perhaps murdering LieutenantWithem? I can't do that. You stay here, Professor. We will take careof ourselves. Don't worry about us. Chunky, you'd better stay herewith the professor. You haven't got sand enough to---"

"What, me stay here?" shouted the fat boy, starting for his own mount. "I guess you don't know what kind of a man I am. Come on, fellows. Whoop!"

Stacy leaped into his saddle. Ned Rector and Walter Perkins alreadyhad taken to their saddles. The professor saw that it was useless totry to stop the boys. He groaned aloud. But Professor Zepplin wasvery active for his years. Ere the enthusiastic Pony Riders hadstarted to gallop away the professor had made a flying leap into hissaddle and a few seconds later was pounding down the canyon, alongthe West Fork, in the wake of the racing Pony Rider Boys. 

"There they are!" cried Tad, as bursting out on the plain they sawvicious flashes of light, accompanied by the crashing of guns. 

CHAPTER IX

SHOWING GOOD GENERALSHIP

Rifles had been jerked from saddle boots as the boys swung to the left, sweeping down over the plain. Tad assumed the leadership of the party, as he usually did in emergencies. 

"All hold your fire until I give the word. Keep your heads. Don't getexcited!" wanted the lad. 

"That is good judgment. But try to keep out of the fire, " shouted theprofessor. 

Ned Rector laughed. 

"We might better have stayed at the camp if that is all we are going todo, " he answered. 

Tad saw that several men were riding around in a circle shooting at afleeing horseman whose rifle spoke often and spitefully. The ladknew that the solitary horseman was the Ranger lieutenant. 

"The cowards---to attack one man that way!" gritted the boy. "Now, fellows, " he called, slacking up slightly, "I want you, when I say go, to yell like mad. Whoop it up for all you're worth. Then when I sayfire, every man shake out his rifle, but shoot high. We don't want tohit anybody unless we have to. We'll make those fellows think thewhole troop of Rangers is turned loose on them. Understand?"

"Good! Excellent head work, Tad. I'm proud of you. But I do hope noneof you gets hit. "

"If you are afraid, drop back to the rear, Professor, " suggested Stacy, whereat chuckles were heard from the others. 

The bandits had not discovered the advancing horsemen in the darkness, though had they been less interested in seeking to kill LieutenantWithem they might have observed the little band that was now sweepingdown on them. 

"Now! Whoop it up, fellows!" Tad raised his voice to an exultant shout. 

Chunky's piercing voice punctured the atmosphere in a blood-curdlingshout, a wild warwhoop. 

"Yip! Yip! Hiyi! Hiyi! Kyaw! Kyeeaw! Yip! Yip!"

Despite the seriousness of the situation and the real desperateness oftheir position the Pony Rider Boys laughed so that they were unable toyell for a full minute. Then they let go their voices, to which theprofessor added his own. But his voice was almost wholly lost in theblood-curdling shouts of his young charges. 

"Ready---Chunky, aim at the moon or you'll be puncturing some of us. Now fire!"

A volley of shots followed Tad's command. Five rifles crashed out, but their leaden missiles went high, followed by another series ofwild yells, whoops and scattering shots. 

About this time the Border Bandits discovered the oncoming party ofhorsemen. All at once they turned their rifles on the Pony Rider Boys. At the first shot in the direction of the boys Tad turned in his saddle. 

"Lie low!" he yelled. "Keep whooping and keep shooting. Look out thatyou don't hit any one. Ride straight at them. They'll give ground. "

"I hope to goodness they do, " shouted Ned Rector. 

"If they don't it's me for the tall timber, " cried Stacy, who hadoverheard Rector's remark. 

The bullets sang so close to the boys that the lads could hear themplainly. Had the light been more certain some of them must have beenhit, for those men out there knew how to handle rifles much betterthan did any of the Pony Rider Boys. 

With wild whoops and yells, keeping up a continuous fusillade, theplucky band kept straight on. 

"It's the Rangers!" They heard the words plainly, uttered by one ofthe bandits. 

"Yip! Yip! Kyeeaw!" screamed the fat boy. 

"Yip! Yip! Hiyi!" chorused the others. 

"We've got 'em on the run!" yelled Tad, as the circling horsemen swungout into a straight line and began racing across the plains, turningin their saddles to shoot at their assailants. 

"Can you see to let them have a few shots into the ground to hurry themalong?" called Butler. 

"Yes, yes, " yelled the boys. 

"Be careful, " warned the professor. Bang, bang, bang, bang! answeredthe rifles of the Pony Rider Boys. The horses of the bandits fairlyleaped into the air. Soon after that they faded into dark, uncertainstreaks on the white of the plain. Now the rifle of the solitaryhorseman began to speak again. Joe Withem was not afflicted with anyscruples against shooting to hit. He tumbled one man out of hissaddle, but the fellow's companions scooped up the wounded bandit, carrying him away with them. Withem thought he saw a man go down, but he could not be sure. 

The boys swept past him some distance to the left of the Ranger, stillshooting, their purpose being to keep the bandits going until thelatter should have been driven so far away that they would not beback that night. 

"Swing back!" commanded Tad. The boys pulled their horses down, andwheeling began trotting back. A little beyond they saw Withemgalloping toward them. 

"You were just in time, fellows. They had me on the hip for sure. "

"I'm glad of it, " called Tad, "for---"

"What's that? Who are you?" interrupted the lieutenant. Then hepulled his horse up sharply. "Well, I'll be jiggered, if it isn'tyou. "

"That's who it is, " laughed Tad. "Are you hit?"

"I stopped a couple, but it doesn't amount to anything. Just fleshwounds, that's all. And you boys put the bandits on the run, eh?"wondered the Ranger lieutenant. "That's another one I owe you. That'sanother one the Cap'n owes you too. "

"Don't mention it. "

"How did they happen to discover you?" asked the professor ridingup beside the Ranger. 

"That's what gets me. I don't understand it at all. They must havecaught sight of me as I was riding out. They surely didn't know Ihad Dunk with me or they wouldn't have begun shooting at me. They'dhave tried to pot the pony in the legs and get me afterwards, thoughI might have stood them off till daylight. "

"Bad, very bad!" muttered the professor. 

"I call it very good, sir. Those fellows have had a fright that willkeep them going for some hours yet. They think it is the Rangers that'schasing them and they'll be hiking for cover at the rate of some milesan hour. "

"You are sure you are not badly hurt?" asked the professor anxiously. 

"If I never get any worse, I'll be satisfied. I'm a marked man, youknow. Some day, when my gun sticks in the holster, I may get mine. "

"Come back to camp with us. Surely you are not going on to-night?"

"Thank you, but I must be getting on. I've got to be at the camp bydaylight. "

"If you think there is danger of your being attacked, we will ride withyou, " said Tad. 

"No, pard, I'm better off alone. I'll know enough to dodge them now. "

"Speaking of danger, you don't suppose these men will come back andvisit our camp, do you?" asked the professor. 

"No, I don't think so. But were I in your place I think I'd put outmy fire and set a guard for the rest of the night. It's always a safething to do. They won't touch you in the daytime; in fact, I thinkthose fellows will be hiding. We'll set a couple of men on their trailjust as soon as I get to camp; now that I know where the trail starts. They know I know, and that's what makes me think they won't let thegrass grow under their feet. "

"I am glad to hear you say so, " answered Professor Zepplin. "I amafraid we should not have mixed up in this affair at all, thoughnaturally I am pleased that we have been able to be of some serviceto you when you might have been killed. "

"And some others with me, " answered the Ranger grimly. "Well, so long. I'll talk with you to-morrow. "

"Good night and good luck!" called the boys. 

"Good night, pards, " answered the Ranger heartily. Swinging his ponyabout he galloped away into the darkness, while the boys turned theirown mounts toward their camp in the canyon. They had done a goodnight's work and Tad's generalship alone had won the battle for theRanger lieutenant. But there were other equally exciting experiencesahead of them in the near future, in which the Border Bandits wouldplay an active part. 

CHAPTER X

THE PONY RIDER BOYS INITIATED

It was rather a solemn party that took its way slowly back to the PonyRider Boys' Camp in the mountains. The boys realized that they hadtaken a rather active part in what might prove for them a seriousaffair. If, by any chance, the bandits learned who had interferedwith them, it might be necessary for Professor Zepplin and hischarges to make lively tracks for the border and seek other fieldsof adventure. 

The same thought was in the minds of all except Chunky, who held hishead erect, his chest swelled out. He was full of their greatachievements and was telling what he would do if any of the banditscame to visit their camp. 

"I think we will put you on guard to-night, seeing that you are such abrave young man, " said the professor with a twinkle. 

"On guard?"

"Yes. "

"Yes, that's the idea. Let him take the watch, " approved Rector. 

"You forget that I'm a wounded man. You forget I've been shot twiceto-day. Huh! Some of you children take the trick. I've got to takecare of my health. "

"I guess if we expect to get any sleep we had better let some one elsedo it, " agreed Tad. "Chunky will have us out on false alarms allnight long. "

They were agreed upon this, and by common consent Butler was given thewatch for the night. The boys slept with their rifles beside themthat night. 

The night passed without incident, Tad Butler keeping a vigilant watchall during the dark hours of the night. He had plenty of time to thinkmatters over. He realized that Dunk Tucker, the prisoner, hadoverheard all that had been said during their talk with Withem out onthe plain. Tad knew that if Dunk ever got into communication with hisfellows it would go hard with the Pony Rider Boys. 

Soon after daybreak, Tad awakened his fellows. He already had a briskfire going, but before lighting it, the lad had walked down to theedge of the canyon for a survey of the plain. He saw a solitaryhorseman far out over the rolling plain. After some study he made uphis mind that the man was going away instead of coming toward them. 

Breakfast finished the party packed their belongings and started outfor their long ride to join the Rangers sometime late in the day. 

About noon they made camp for dinner and a rest, not taking up theirjourney until about four o'clock in the afternoon. Darkness overtookthem, finding them still without sight or sound of the Spring whereWithem said they would find the Rangers' camp. A consultation was heldand it was decided to continue on until they picked up the party. 

About half an hour after night had fallen, they were riding along whensuddenly they were stopped by a stern command. 

"Halt! Hands up! Every man of you is covered!"

"Oh, wow!" gasped Chunky. "They've got us again. "

"Who are you?" demanded the voice. 

"Who are you?" returned Tad boldly. 

"I reckon my question gits the first answer, seeing as I've got thedrop on you. "

Tad all at once realized that the sound of falling water was in theair. With it came the thought that these must be the Rangers. 

"We're the Pony Rider Boys, " he said, speaking confidently. 

"The which?"

He repeated his answer. 

"Wait a minute. Send for Joe, " said the man in a lower tone. "Youfellows stay just as you are if you don't want some daylight letthrough you. "

"I---I wish we did have a little daylight, " stammered Chunky, whichelicited a short laugh from his companions. "Yeow!" bowled the fatboy as a figure appeared beside him and a pair of iron arms graspedhis hands pulling him down, nearly unseating him. "Yeow! Let go!"

"It's all right, boys, " spoke up the familiar voice of LieutenantWithem. "I'd know this fellow in the dark as well as in the light. I'm Withem. "

At the lieutenant's reassuring words the Rangers---for the boys hadstumbled upon the camp of the men of Captain McKay's command---crowdedforward, talking and laughing, three of them taking the horses as theparty dismounted, then leading the way into the bushes and in amongthe rocks where the lads came upon a campfire, around which wereseated five or six other Rangers. 

Withem introduced the professor and his charges. There were, besidesthe Lieutenant, Pete Quash, "Dippy" Orell, Cad Morgan, Bucky Moore, "Polly" Perkins and several others, all of whom were introduced inturn, the Rangers solemn as owls, making low bows, sweeping the groundwith their sombreros, causing Stacy to open his eyes in wonderment. Lieutenant Withem made the party feel at home at once. 

"Just in time to have chuck with us. You see we have our chuck wagonhere. Of course we don't carry it wherever we go. We usually havesome central point where we make headquarters. But we have to keepchanging these headquarters for reasons you understand. "

All hands sat down to the evening meal after the men had washed up, inmost instances without removing their hats. This attracted theattention of the fat boy. 

"Say, do you fellows sleep in your hats as well as wash and eat inthem?" he demanded. 

"Do you sleep in your skin?" retorted Dippy. 

"Yes, unless it has been all skinned off from me. When I was fightingIndians up in the Grand Canyon---"

"Chop it!" commanded a Ranger. "Men have been known to meet their deathfor less in this country. "

"Can't I say what I've got to say?" demanded the fat boy indignantly. 

"Are you going to brag about yourself?" demanded Polly. 

"I'm telling you, and---"

"Well, don't tell us. We don't want to have to take you out and tieyou to a tree. Say, will you get wise to the dude with the rednecktie?" scoffed the Ranger, pointing to Ned, who, in the place of thebandanna handkerchief, had put on a flowing tie of brilliant red, tying it about his neck, with the ends carelessly thrown over the leftshoulder. 

"Don't you like it?" asked Ned, flushing. 

"Like it? Why, it's the hottest thing that ever crossed the StakedPlains since the Apaches came down in---"

"Why don't you look the other way then?" interjected Stacy. 

"Oho! Listen to the human monstrosity---the monstrosity as wide as heis long and as fresh as he is stale. What you got to say about it, young man?" demanded Dippy, glancing at Tad Butler, who was smiling. 

"I haven't said anything yet. "

"But you're going to?"

"I may. "

"Can we stand for any more remarks, boys?" asked Dippy. 

"No, we can't stand for any more, " chorused the men, the professor andthe lieutenant being too busy with a discussion to pay any heed to whatwas going on about them. 

"Then he shall be washed clean so that he may take a fresh start?"

"That's the idea!"

"Will you go peaceably or must we drag you?"

"I reckon you'd better drag me. If you're going to have fun with meyou'll have to earn it. I don't propose to help you out. "

"Do you hear?" demanded Dippy in a deep, hoarse voice. 

"We hear. "

"Then do your duty!"

Two men grabbed the Pony Rider boy up, Tad making no resistancewhatever, a little to the surprise of the men who had taken hold ofhim. They expected the boy to resist, which would have given themstill further excuse to handle him roughly. But Tad was used todealing with the rough and ready characters of plain and mountain. He didn't care particularly what they did. The other boys weredelighted that Tad was to be made the mark this time. They followedalong laughing and jeering at their companion. 

The Rangers fell in behind the two who were carrying Butler, in solemnprocession. To look at their faces one would have thought they wereperforming a solemn duty. The boys wondered where it was going to end. They discovered a few minutes later. Tad was taken out where thegentle murmur of the Spring falling over the rocks could be heard whenthe Pony Rider Boys were not making too much noise. 

"Do you withdraw the flippant words you used to a member of this augustbody?" demanded a deep voice. 

"No!" cried Tad Butler. "Never! I'll die first!"

"Then take your punishment!"

With that they gave the boy a swing, one holding to the feet the otherthe shoulders of the lad. When they let go, Tad sailed several feetthrough the air. Quick as a cat in his movements Tad turned overbefore he landed, going down on all fours. He thought he was going tostrike on the hard ground. Instead he landed at the bottom of a deeppool of water cold as ice it seemed to him. He went in all over. Notexpecting anything of this sort the boy was not holding his breath. The result was that he got a mouthful of water. He came up choking, then pretended to go down again. Instead he crawled up to the bank, under which he hid. 

A moment passed and the Rangers began to be alarmed. Dippy steppedto the edge of the pool and leaning over peered down somewhat anxiously. 

Quick as a flash a pair of arms encircled his neck. Dippy plungedin head first. He did not even have time to cry out. The others, discovering that Dippy had fallen in, rushed to the edge shouting andlaughing. Two of them went the way of their companion, Tad havingjerked their feet from under them. Within sixty seconds from that timehalf of the crowd were threshing about in the cold waters of the pool, while Tad, who had crawled out, sat on the bank dripping, watchingtheir struggles. 

Stacy Brown was rolling on the ground, howling with delight. All atonce he was picked up in a pair of strong arms and tossed in bodily. Stacy howled lustily. Clambering out he squared off for fight, but theonly fight he got was another ducking in the pool. 

"You---you----you fellows ought to be ashamed to pick on a wounded manthat way. Don't you know I've been shot?"

"Shot?"

"Yes, shot. "

"He's been shot, " chorused the boys and the Rangers together. 

"Any of the rest of you kiddies been wounded in the fracas?" demandedFolly. 

"No, but you've overlooked two of us, " announced Ned stepping out. "Wehaven't had our baths yet and I reckon we need them. "

Without a word, two of the Rangers got up and threw the two remainingboys into the pool. Ned went in with a mighty splash, Walter Perkinslanding on top of him, nearly taking away the breath of Rector. Theyhad a rough and tumble scrimmage in the cold water, coming out choking, dripping and laughing. 

All this made a favorable impression on the Rangers. Boys who couldtake rough handling such as this, without losing their tempers or evenoffering any objection, surely must be worth while. Then, too, therewas the story about Tad and Ned having captured the desperado, DunkTucker, who was now well on his way to the calaboose in El Paso. 

"I reckon you kin go back and dry off now, " drawled Dippy. "Anythingelse you cayuses reckon you want?"

"Yes, you might fetch me a piece of soap, " answered Butler laughingly. 

"I reckon you'll use sand, young man, " answered Orell witheringly. 

The Pony Rider Boys made their way back to the camp, wet but happy, theonly dissatisfied one in the crowd being Stacy Brown. But theirtroubles for the night were not wholly over yet. Their initiation wasnot yet complete. The Rangers had still other plans for their visitors. 

CHAPTER XI

BAG-BAITING THE 'POSSUMS

"Guess you fellows are forgetting about that 'possum hunt?" drawled CadMorgan as the boys came noisily into camp. 

"'Possum hunt?" cried Stacy, brightening at once. 

"I wasn't talking to you, " answered Morgan witheringly. "Don't breakin when men are talking. "

"Men? Where are your men? I want to go 'possum hunting, too. "

"So do I, " chorused Ned and Walter. Tad did not speak. He waswatching the Rangers to see if they meant it. Evidently they did. 

"That's so, " answered Dippy. "We had plumb forgotten all about it. We better get a move on or we won't have that 'possum for breakfast. Ever go bag-baiting for 'possum?" he demanded wheeling on Tad. 

"I never did. "

"Neither did I, " interjected Stacy crowding in between Tad and theRanger. "I want to bag a 'possum. "

"Better look sharp or the 'possum will bag you, " warned Pete Quash. 

"I guess I'm not afraid of any 'possum that ever climbed a tree. Haven't I killed lions and bob cats and fought Indians, and---"

"Stop it!" roared Dippy. "I'll be worse'n my name if you keep fillingme up with that line of talk. "

"What's bag-baiting 'possum?" asked Walter. 

"What! You never heard of bag-baiting?" demanded Cad. 

"I never did. "

"Well, you fellows are tenderfeet!"

"May we go along and help?" asked Chunky. 

"What do you say, fellows?"

"We might let them on a pinch. I suppose they've got to learn sometime. "

"All right, you fellows may go out and help us, but it's a job, mindyou! You'll get sick of it before you've finished. "

"No we won't, " cried the boys. 

"Well, I reckon we'd better be getting the stuff together, " said Cadgetting up wearily. "Though I'm afraid the roly-poly will plumb scareevery 'possum out of the community. "

"If they don't run at sight of you, they'll stand for anything short ofa ghost, " retorted Stacy sarcastically. 

Cad did not reply to this fling. He merely grinned. Tad saw more inthat grin than did his companions, but he held his peace. He wantedto see the fun, even if it were still further at his own expense. 

Preparations for the 'possum hunt were at once begun. Two burlap sackswere procured from somewhere in the camp. These, with several candlesand some stout sticks, made up the outfit for the 'possum hunt. 

"Where are you fellows going?" called Withem as he saw the outfitstarting away. 

"Hunting 'possums, " answered Dippy. 

Lieutenant Withem smiled. 

"I hope you bring back some for breakfast, " called the professor. "I amfond of 'possum. "

"You won't be of the 'possum they catch, " warned the lieutenant, in alow tone. 

With pistol holsters slapping against their thighs, Rangers and PonyRider Boys strode from the camp, circling to the left after leavingthe rocky pass where they had their resting place. They followedaround the base of the mountains for a half mile. The ground wasthickly wooded with second growth and mesquite bush. 

Cad finally called a halt. 

"I reckon we'll go in here, " he said. 

"Going to leave a bag here?" asked Polly. 

"Sure. Here you, Perkins, catch bold of the bag. "

"What do I do?" asked Walter. 

"Wait; I'll show you. "

Morgan very carefully lighted a candle and stuck it into the ground, packing the dirt about it with his knife. 

"Now you hold the bag open. Don't move. Don't jump if you see a'possum light into the bag. You see the light draws them. Ithypnotizes them and they jump right into the light. That means theyjump into the bag. The minute one hops in all you have to do is toclose the bag, sling it over your shoulder and hike back to campwith it. "

"That's easy. I could catch 'possums myself if that's all a fellow hasto do, " declared Stacy. 

"It'll be your turn next, Fatty. "

It was. After floundering through the bushes for some distance theRangers stopped. 

"Now, Fatty, it's your turn, " announced Cad. "You may have to waitaround here for an hour or two while we beat up the bushes and drivethe 'possum in, but you won't care. You'll be glad you stayed when youget a nice fat 'possum for your breakfast. "

"I'll catch him if he comes this way, " replied the fat boy. 

"You bet you'll catch it, " chuckled Dippy. 

"How long do I stay here?"

"Till you git a 'possum, " answered Polly. "Mebby that'll be in twominutes and mebby not in two hours, but you've got to stand very still. If you move you'll scare the whole pack of them back into their holes. "

Stacy squared himself, holding the opening of the bag close up to theburning candle. 

"That's right. A little more to the left with the opening, " directedCad, who had constituted himself the master of the hunt. "Now holdit. You other two lads work around the outside. One of you go to thenorth, the other to the south about a quarter of a mile, then workgradually in, beating the bushes, slamming these clubs against everytree you come to big enough to hold a 'possum. In that way you'lldrive them in. "

"Yes, sir, " answered Tad and Ned very solemnly. 

"And go slow. Just take a step at a time, or some of the birds may getby you. "

"A 'possum isn't a bird, " corrected Stacy. 

"You'll think it is after you've hunted one for an hour or two. Now gitgoing, you beaters. Imagine you're beating the bush for lions. Thatwill keep you from going to sleep on the job. "

Chunky's eyes grew large. 

"See here, you don't want to stand up straight, " rebuked Morgan. "Youmust lean over just like this, " bending himself almost double with hisnose close to the ground. 

For a half hour Stacy Brown maintained his position. By this time hisback was aching, perspiration was running down his face and neck inrivulets. Insects of many shapes and forms, attracted by the light, were hopping about, some getting into the fat boy's eyes, nose andears, others getting under his clothing. But still he held the bagopen. No 'possums came his way. Some few thousands of insects did. A large part of these hopped into the bag. Others crawled in. 

In the meantime Tad, his face wearing a grin, had walked away, butinstead of beating the bush for 'possum, he headed straight for thecamp. He heard the Rangers off to the left, as he emerged from thebush. The men were laughing and talking. Butler reached the campahead of them. When they came in they were amazed to see himstretched out comfortably in front of the campfire, taking his ease. 

"I thought you were hunting 'possum, " cried Polly. 

"I thought you were hunting 'possum, " laughed the others. 

The men looked into each others' faces, then burst out laughing. 

"Where's the other one?" meaning Rector, who like Tad was to drive the'possums in. 

"He's hunting 'possum, " answered Tad. An hour later Ned Rector camesauntering in. 

"Hullo, did you drive out any 'possum?" called Cad. 

"Narry a 'poss, " answered Ned carelessly. "I thought I'd leave themfor you fellows. I didn't want to hog the whole game, you know. "

"Are the other two holding the bags open?"

"I don't know. I suppose they are. They'll be even with you forthat, " answered Ned. 

"By the way, Mr. Withem, " said Tad strolling towards him, "I thought wewere going to meet Captain McKay here. "

"The captain is not here, " replied the lieutenant with some reservationin his tone. 

"Will he be here before we leave?"

"I can't say. Captain Billy may be here in the morning, then again hemay not. If you miss him here, he will see you some other time. Hewants to know you, pardner, " smiled the lieutenant. "Where is thefat boy?"

"Holding the 'possum bag down in the bush, " answered Tad with a grimsmile. 

The Rangers were pulling off their boots and one by one crawling intothe single tent that did duty as a bedroom for all except the officers, who had a small tent to themselves. The boys were chuckling tothemselves. They thought they had a good joke on at least one of thePony Rider Boys, and perhaps they had. 

About two hours after the men had returned to camp, Walter Perkins, withan exclamation of disgust, threw down his bag. 

"Let them catch their own 'possums, " he said. "I don't believe thereare any 'possums in this country to catch. Even if there were wenever could get them in a bag this way. I'll bet they have beenplaying a joke on me. I'm going back to camp. "

Half an hour later, Chunky, his back aching like a sore tooth, straightened up with evident effort. The fat boy began to see alight, other than that furnished by the candle. 

"I guess I'm the goat, " he said regarding the bag reflectively. "Yes, I am the goat all right. "

Picking up the candle, Stacy peered into the bag, then he thought somemore. The inside of the bag was literally alive with insects. The fatboy quickly closed the bag, twisting the mouth tight and tying it fastwith a string. Then blowing out the candle, he shouldered the bag, setting off for camp as Walter had done some thirty minutes before. But Stacy failed to observe the figure of a man near by as the boystepped out on the plain. This figure followed along behind him at asafe distance, the man chuckling to himself as he watched the boy andthe bag. The mysterious stranger was the Ranger lieutenant. 

Reaching the silent camp, Stacy slunk in, apparently seeking to avoidbeing seen. The grinning lieutenant saw the boy slip cautiously tothe tent occupied by the sleeping Rangers. There the fat boy verycarefully deposited his 'possum bag, first having opened the mouth ofit, after which he slipped away to his own tent and crawled into bed. But Stacy did not go to sleep at once. He lay there listening, gazing up at the roof of the tent through which he could make out thefaint light of the sky. 

Some twenty minutes elapsed when the boy sat up, thinking he had hearda sound from the other tent. This became a certainty just a fewminutes later when a great uproar arose in the tent of the Rangers. Loud voices were heard, threats and shouts. The hundred and fifty-eightvarieties of bugs that the fat boy had brought in in his 'possum bag, were getting in their deadly work on the persons of the Rangers. Chunky had turned the tables on his tormentors most beautifully. 

CHAPTER XII

INSECTS WIN THE BATTLE

The Rangers, slapping, scratching and fighting against the armies ofinsects that were crawling over them, had finally got out of bed andgone out of doors to sleep. But there was no rest there either. Their bodies were covered with ants and fleas, all withwell-developed biters---and they bit!

At first the Rangers did not realize the trick that had been playedupon them. One who went back to the tent for his hat discovered theburlap sack that had been used in the 'possum hunt. He brought it out, holding it up before his companions. The Rangers eyed the bag, thengazed at each other solemnly. 

"Stung!" groaned Dippy. 

"Bitten, you mean, " answered Cad Morgan. 

"Which one played that low-down trick on us?" demanded Pete Quashangrily. 

"I reckon it was Fatty, " said Polly. "He's the one that would havethought of a thing like that. I reckon there must have been a millionof those bugs crawling over me. "

"I'll tell you what, fellows. Let's get Fatty out and tie the sackover his head. We'll give him a dose of his own medicine, " proposedDippy. "We can't stand for anything of this sort. "

"Look here, boys, " spoke up Cad. "Are you welchers? Can't you takeyour medicine without squealing?"

"What do you meant" demanded Polly. 

"I mean that we fellows put up a job on the kids. The fat baby turnedthe joke on us, and right smart at that. We're It. We're full ofbugs---the worst biters anywhere between the Rio Grande and thenorthern border. Are we going to squeal? I reckon we aren't. We'regoing to stand here and let the biters do their worst. I'm mightynear eaten alive, but I'm taking my medicine and I reckon I'll betaking a lot more of the same dose before morning. "

"Wal, " drawled Polly, "I reckon you're right at that, Cad. But I'dlike to wring that little cayuse's neck just for luck. "

The "little cayuse" referred to was sleeping sweetly in his tent, untroubled by the distress of the Rangers. 

All that night the Rangers walked up and down, slapping their thighs, scratching their legs, for the older the night grew the harder didthose fleas seem to take hold. 

"I reckon their bills will be so dull by morning, after drilling ourtough hides all night, that we won't feel them at all, " observed Polly. 

A low growl from Dippy Orell was the only reply to the remark. Now andthen a man would throw himself down hoping to get a brief nap, but a fewmoments later he would be up stamping and scratching and growling deeply, threatening vengeance on the boy who had played the trick on them. 

Next morning, Stacy Brown, for reasons best known to himself, got upahead of the others of his party. Stacy took his time in dressing, thenstrolled out. 

"Hullo, I guess the crowd is sleeping late this morning, " he muttered. Then he halted. His eyes rested on the 'possum sack that he had leftin the tent of the Rangers the night before. A broad grin spread overhis face. 

"I guess they won't be playing monkeyshines on Stacy Brown right away. I wonder if they got bitten much? I'm all swelled up where the insectsmade a meal on my skin. Hullo! Hi, fellows!"

Tad Butler and Ned Rector appeared at the door of their tent almost atonce. 

"Can't you let a fellow sleep?" demanded Ned. "What's the row about?Got a 'possum for breakfast?"

"No, but I've got something else for you. "

"What's that?" questioned Butler. 

"A surprise. "

"What kind of a surprise?"

"Just a surprise surprise, that's all. What do you think?"

"Too early to think. I'm going back to bed, " growled Rector. "Anddon't you dare wake me up again. "

Tad stepped out. 

"The crowd has given us the slip, " announced Stacy. 

"What---why they've gone!" exclaimed Tad. 

"Yes, they've gone. Gone where there aren't any Pony Rider Boys tomake life miserable for them. "

Tad was mystified. The Ranger company had disappeared utterly. Theyhad slipped away silently and mysteriously. Even the chuck wagon haddisappeared. 

"Why, what can it mean?" marveled Tad Butter. 

"You may search me. I don't know. "

"Hey, Ned!"

"Well, what is it?" growled Rector appearing at the tent opening again. 

"They've gone and left us and without even saying good-bye, " called Tad. "Shake out the others. "

The professor and Walter, having been awakened by the talking, nowappeared. They were quickly informed that the Rangers had left, atwhich they wondered not a little. 

"I guess they got tired of our company. I'm going to start breakfast, "declared Butler. 

"This is most remarkable, " bristled the professor. "I should havethought they would have left some word. "

"How about that 'possum, Chunky?" jeered Rector. 

"You better ask the Rangers. They'll tell you about that, " answeredthe fat boy with a grin. "There's the sack in which I fetched theanimals back to camp. "

"What, did you catch any?" demanded the professor. 

"Oh, I got some game, all right. I'm the champion hunter, I am. Say, I wish I could cook like you, " said Chunky gazing admiringly at Tad, who was confidently making some biscuit for breakfast. "I never couldcook unless I had everything all down in writing before me. How do youdo it?"

"Oh, he cooks by ear, " scoffed Ned. "That's why there's so manydiscords in our digestive apparatus. "

The Pony Rider Boys groaned dismally. 

CHAPTER XIII

AN INQUISITIVE VISITOR

Breakfast the plans for the day were discussed. The professor was forremaining in camp, hoping that the Rangers might return later in theday. Tad did not believe this would be the case. He reasoned thatthe men had been summoned some time during the night to go on a hike, and that they might not return at all; therefore the Pony Rider Boyswould be losing time, whereas they might be exploring the Guadaluperange, which stretched away for a hundred miles. 

"Still, I can't understand this mysterious departure of our friends, the Rangers, " persisted Professor Zepplin. 

"Perhaps it was the bugs, " suggested Stacy wisely. 

"The bugs?" questioned the professor. 

Chunky nodded. Tad eyed the fat boy suspiciously. 

"Look here, what have you got up your sleeve, Stacy?" he demanded. 

"Nothing, I hope. But some of the fellows did. "

"Did what?" cut in Rector. 

"Did have. "

"Did have what?" urged Walter. "A fellow has to have a map to followyou. "

"Did have something up their sleeves. "

"What was it you think they had up their sleeves?" asked Tad, eyeingthe fat boy with growing suspicion. 

"Oh, I don't know. Maybe it was insects. "

"Stacy!" rebuked the professor sternly. Tad recalled that he haddiscovered thousands of insects crawling over the burlap sack whenhe came out in the morning. The lad's mind began to unravel themystery. He thought he understood Chunky's references now, but Tadonly smiled. He made no effort to explain, but instead, changed thesubject. 

"Do we start, or do we remain here, Professor?" he asked. 

"It shall be as you boys wish. All in favor of going on will say 'aye. '"

"Aye!" howled the Pony Rider Boys, a shout that caused the browsingponies to look up in mild surprise. 

"Then we move. I will say, however, that I don't exactly approve ofthe situation. "

"What situation, Professor?" questioned Butler. 

"There are too many rough men in these parts. I had no idea we weregoing to meet with any such condition of affairs in this enlightenedstate. "

"That's nothing. We have had some experience. Experience is what weare looking for. "

"But the Rangers were not, " asserted Stacy thickly, his mouth full ofbiscuit. "They got it, though. "

"I feel sorry for you, " said Tad leaning over to Stacy. 

"Sorry for what?"

"For what you'll catch when they get hold of you again. "

"They'd better not. I've got something up my sleeve, or I will have, I mean. They'd better keep away from me. "

"Come, fellows, are you going to strike camp while I clear away thebreakfast things?" called Tad. 

"Let Chunky do it. He hasn't done a thing this morning, " cried Ned. 

"Yes, I have, too. "

"What have you done?"

"I've done two things this morning. "

"That's news, " grinned Walter. 

"Yes, name them. We don't want to do you an injustice, you know, " urgedRector sarcastically. 

"I made a discovery---I discovered that we had been basely deserted. "

"Well, that's only one thing. You said you had done two things, "persisted Ned. 

"Then I ate my breakfast. That's two things. "

The boys groaned. 

"He ate his breakfast. Most remarkable, " scoffed Rector, imitating theprofessor's voice and manner, whereat the professor himself grinnedbroadly. 

Tad, giving up expecting the others to do anything, was rapidlygathering their equipment together. The tent came down. He dividedit into sections, placing the sections in piles preparatory to formingthem into bundles to be packed on the ponies. 

"Have you the map, Professor?" he called. 

"In my saddle bag. "

"I want to study it a minute before we start. We don't know anythingabout the trails here and we have no guide to direct us. We've got tomake our way the best we can. "

"We can't get lost, " chimed in Chunky. 

"Why can't we get lost?" snapped Ned turning on the fat boy. 

"Because we don't know where we are anyway. "

"Horse sense, " laughed Tad. 

"Fat-boy drivel, " jeered Ned. 

"Come, come, young men. You are not making much headway. "

Stacy dragged his pack by the rope, over to his pony, instead ofcarrying the bundle as he should have done, Professor Zepplin observingthe boy with disapproving gaze. 

"Is that the way you have been taught to pack your pony, sir?"

"No. I've never been taught. What I know I've had to pick up. Nobodyever tries to teach me anything. "

Scolding, joking, having all manner of sport with one another, the PonyRider Boys finally completed their tasks. The ponies were loaded, thepack pony was piled high so that its head and legs were about the onlyparts of its anatomy visible, and the boys climbed into their saddles, Tad first having given the trail map a brief scrutiny. 

They started off up the canyon. For a little way the trail appearedto be no trail at all. The ponies threshed through the bushes, thesharp limbs smiting the riders in the faces, making disagreeabletraveling. But the young men were used to this sort of thing. Theydid not appear to mind it at all. 

Reaching a higher altitude they found the trail to be fairly good. From there they got a good view of the yellow plains below, thatstretch away many miles to the northward. To the southwest, peaksthat they judged must be all of four or five thousand feet high, towered blue and hazy in the yellow light. Birds were singing, theair was soft and balmy and a gentle breeze stirred the foliage aboutthem lazily. 

"This is what I call fine, " cried Tad. 

"Good place for a nap, " agreed Chunky. 

"Are you in need of sleep?" asked the professor. 

"I'm in a trance, sir. "

"You always are, " laughed Tad Butler. "I think we had better take arest here. The animals are tired after the climb. Suppose we lieoff for an hour?"

The boys were all agreed on this, so the pack pony was unloaded. Itnow being near midday it was decided to wait for dinner before pressingon. A meal was a "dab" down there and the boys had fallen naturallyinto the vernacular of the men of the plains. 

It was Ned's turn to cook the "dab, " a task that never appealed to him. Chunky at such times was always on hand while Ned was getting the meal, that he might offer suggestions and make uncomplimentary observations. Rector's method of making coffee came in for considerable criticism. He never could be induced to make coffee after the more approvedmethods. Ned's way was to put a pint of coffee beans in a two-quartcoffee pot and boil for half an hour. He made it the same way on thisoccasion. 

"That stuff would eat a hole through a piece of sheet iron if given halfa chance, " declared Stacy. 

"Don't worry. It won't hurt you, " retorted Ned. "Your stomach is toughenough to withstand anything. "

"I guess it is or I'd have been dead long ago eating your dab, " flungback Stacy. 

They had to wait quite a time for the coffee, but at last the call todinner was sounded in the usual way, the long-drawn cry of, "Come andget it!"

They had just sat down when they were startled by a voice calling fromsomewhere off in the bushes to the northward of them. 

"Hoo-ee!"

The boys started up, thinking that perhaps some of the Rangers hadreturned. Instead of the Rangers a stranger rode in on a wiry littlepony. He doffed his sombrero gracefully and sat regarding themsmilingly. 

"Howdy, pardners, " greeted the newcomer. "Got a smack for a hungry man?"

"Certainly, certainly. Come right over, my friend, " answered theprofessor cordially. 

Ned stepped forward politely to take the stranger's horse. 

"Never mind, lad. I'll look after the cayuse. He isn't over-fond ofstrangers. You're all strangers down here, eh?"

"Yes, yes. We are, " admitted the professor. "You are just in time. We are ready for dinner and there's plenty to go round. "

"I'll promise not to eat you out of house and home, " laughed thestranger. Without taking off his broad-brimmed Mexican sombrero hethrew himself down by the piece of canvas on which the dinner hadbeen laid, helping himself to a slice of bacon which he ate from hisfingers in a most democratic fashion. "My name's Conway. BillConway. What's yours?"

Professor Zepplin introduced himself and the boys, which Conwayacknowledged by polite bows. The man was easy in manner, and hissmiling face led the boys to warm to him at once---all save TadButler, who, without appearing to do so, was observing the visitorkeenly. 

The man was slight, almost boyish in figure. His hair was dark, aswere his eyes, the latter having a trick of growing suddenly darkerthan their natural color, seeming to sink further back in his headunder some sudden stress of emotion. The brown fingers were slenderand nervous in their movements. 

"I'll bet he would be quick on the trigger, " was Tad's mental conclusion. 

"Are you from these parts?" asked the professor by way of starting theconversation. 

"El Paso, when I'm at home. And you?"

"From the north. "

"Down here for your health?"

"Partly. Mostly for an outing. "

"Just so. I reckon I've heard something about you. "

"Maybe it was I whom you heard about, " suggested Chunky. 

"Can't say as I have, " answered Conway, directing a quick glance atthe fat boy. 

"You don't know what you've missed, " answered Stacy solemnly, helpinghimself to five slices of bacon. 

"You didn't happen to meet with any of the Rangers this morning, didyou?" questioned Professor Zepplin. 

It was the professor's turn to get a sharp look now. 

"Rangers? No. Why do you ask?"

"Because we were looking for some of them. "

"What for?"

"We wanted to see them about a little matter, " hastily interposed TadButler. 

"What matter?"

There was no stopping the professor. 

"Why, we camped with a body of them last night. With LieutenantWithem, a most affable gentleman. They ran away and left us earlythis morning. However, I suppose they had good reasons. "

"Joe Withem, eh?"

"Yes, that was the man. "

"How many Rangers did behave with him?"

"Twelve, wasn't it, boys?"

"Something like that, " replied Tad, observing their visitor narrowly. "However, Professor, I hardly think we should speak of them. You seethey were on some secret mission and---"

"It's all right, young man. You are safe in confiding in me. In fact, I am going to confide a little secret to you to show you that you havemade no mistake. "

"We shall preserve your secret, sir, " answered the professor with greatdignity. 

"I thought you would. Lean closer and I'll tell you, " almost whisperedthe visitor. 

CHAPTER XIV

WHEN THE AIR GREW CHILL

"I'm a Ranger, too, " confided the visitor. 

"What, you a Ranger?" exclaimed the professor. 

"Of Captain McKay's band?"

"You've hit it, pard. "

"Well, well, this is indeed a pleasure. We have not had the honor ofmeeting Captain McKay as yet, but we hope to do so, ere long. He hadpromised to meet us last night, but I understand was called away onsome business pertaining to his calling. "

"You would like to meet Captain McKay?"

"Indeed I should. I understand he is a most remarkable man, that hehas performed many deeds of valor. "

"Pray stop!" laughed Conway. "You actually make me blush. "

The outfit gazed at the visitor inquiringly. 

"Now that you have said so much I am going to confide another littlesecret to you. I'm McKay. "

"What? Not Captain McKay, the leader of the Rangers?"

"The same. "

Professor Zepplin thrust a brown hand across the table, grasping thehand of their visitor. 

"Well, this is indeed a surprise. I can't begin to tell you how gladwe are to see you, " answered the professor with enthusiasm. 

"Same to you, pardner, " grinned the captain. "You see I didn't wantto open up too freely until I was sure to whom I was talking. Ofcourse if you and Withem are cahoots, it's all right. "

"It certainly is all right. We had the pleasure of being of someservice to Lieutenant-----"

"Ouch!" howled Stacy. Tad had tipped the pot of hot coffee into thefat boy's lap, and for a few moments confusion reigned. 

"Don't talk too much, " whispered Butler leaning over to brush awaysome drops that had fallen on the professor's shirt. 

"Eh? Eh? What's that?"

Tad was embarrassed. He began speaking of something else. ProfessorZepplin did not repeat his question. 

"I understand my men picked up a fellow named Dunk Tucker a night ago?"asked the captain. 

"Yes, yes, indeed. Mr. Butler there is the one who is really responsiblefor the capture of Tucker, however. "

"You don't say!" wondered the visitor. 

"Exactly. Tad, will you tell the captain how you came to capture theman Tucker?"

"If you will pardon me, I would rather not. "

"He's too modest. I'll tell you about it, " chimed in Stacy Brown. Stacy, once wound up, would continue to operate until he had run down. He told the whole story from beginning to end, including the fact thathe himself had been wounded twice, ere he stopped. 

"Fine, fine!" The captain leaned back and laughed uproariously. "Youare a funny boy. I wish I had you with me. I could teach you a lotabout dodging bullets. "

"I'm a pretty good dodger already or I shouldn't be here at thisminute, " answered the fat boy pompously. 

"Where did they take the prisoner? Are you informed as to that?" askedthe captain. 

"They took him to El Paso, I believe, " replied Professor Zepplin. "Ithought you were aware of what had been done. "

"I got wind of something of the sort. You see I have been away inanother part of the state on a secret mission for the Governor. "

"Exactly. "

"Did my men say where they were going before they left you thismorning?"

"No. As I have said, they left most mysteriously. "

"Which direction did they take?"

"We do not know that either. They disappeared utterly. "

"Just like Withem, " nodded the guest, smiling. "But I'll pick him upsome time to-night. I suppose they are on the track of some of thefellows who have been raising trouble around these parts of late. "

"Yes, that's what the lieutenant said. They are after what they callthe Border Gang. But I have no need to tell you about it. You surelyare familiar with the subject. "

"I reckon I know all about it, Professor. Was it some of my men whoshot up the bandits the other night and---"

"No, that was us fellows, " interjected Stacy suddenly. "We did givethem the run. And they thought it was the Rangers too. Oh, that wasa good joke. I nearly laugh myself sick every time I think aboutthat funny scrape. We bluffed them and they ran away. "

For the briefest part of a second the eyes of the visitor darkened. They grew almost filmy, then the old sparkle came into them and agrim smile appeared on the face of their owner. 

"You sure are a fine crop of youngsters. You probably will be claimingthe reward for the capture of Tucker, eh?"

"Not at all, not at all, " protested Professor Zepplin. "My young menare not looking for rewards. It is reward enough that they were ableto serve the authorities in the capture of a very bad man. We shalldo whatever we can in our small way to help the Rangers round up therest of this disreputable gang. "

"Of course, of course, " answered the captain reflectively. 

Tad had taken no part in the conversation. He did not like thisfreedom of speech on the part of the professor. What they had learnedwere better kept to themselves according to Tad Butler's reasoning. Then again there was a faint suspicion in the mind of the Pony RiderBoy, that he could not clearly explain to himself. What did strikehim as peculiar was that so much of the Rangers' movements should beunknown to their commanding officer. McKay had ever since coming intotheir camp been seeking information. Still, as he had said, he hadbeen away. Tad knew that the Rangers took long rides, sometimeshundreds of miles, using relays of horses and making almost as goodtime as they could have done going by trains. 

The lad decided that he was unduly suspicious. Suddenly, as McKaywas talking, a shot sounded somewhere off on the plains. The Rangersprang to his feet, his eyes darkened. 

"Is---is something wrong?" stammered the professor. 

"There may be. I must investigate. You will say nothing about havingmet me, " commanded the stranger sternly. 

"Certainly not, certainly not. "

"I will bid you good day. I'll see you again when I may have somethingmore to say. "

With that McKay ran to his pony, and leaping into the saddle torethrough the brush at a perilous pace. Tad observed what the othersfailed to see. He noted that the Ranger had returned in the directionfrom which he had come, rather than riding off toward the directionfrom which the shot had sounded. This struck Tad as a peculiar thingfor a Texas Ranger to do. 

"That's queer, " muttered Butler. 

"What is queer, Tad?" questioned the professor. 

"The way he went. "

"His leave taking was rather abrupt. But we know that is a way theseRangers have. Besides he thought there was trouble in the air, "guessed the professor. 

"Yes, but then why did he run away from it?" urged Butler. 

"That's so, he did go the wrong way, " wondered Ned. 

"Maybe he's going to take a roundabout course, " suggested Stacy. 

"Exactly. You do think now and then, don't you?" smiled the professor. "However, it is not for us to criticize. Captain McKay knows hisbusiness perhaps much better than do we. And now, if you are readywe had better be on our way. We have lost no little time here. "

The packing up was not a long job for not much of their equipment hadbeen unloaded. The rest of the day passed uneventfully, the PonyRider Boys continuing along the range of mountains. 

About five o'clock they decided to make camp in a valley, beside astream of clear, cold water. The place was thickly covered with brushand small trees, excepting for a small open space on which the grassgrew high and green. 

They pitched their tent near the stream. This done the boys begangathering dry wood for the campfire which would need a lot of itbefore the evening came to an end. Wood was scarce and darknesshad overtaken them ere they succeeded in getting enough for theirneeds. In the meantime the professor had been laboring with the tent. He had finished his job quickly, rather to the surprise of the boys, who were chuckling over the mess Professor Zepplin would make of it. The professor, however, was far from helpless. He might not besuspicious of every one he met, but he was a man of brains. He knewhow to get along with his young charges, as perhaps few men wouldhave done. And he did get along, without friction, retaining thelove of every one of the Pony Rider Boys. They were always ready toplay pranks on the professor, yet there was not a lad of them butwould have laid down his life, if necessary, for him. 

He insisted on getting the supper, "just to keep my hand in, " as heexpressed it. No one offered strenuous objection to this, thoughno cook ever had a more appreciative audience. The professor'sbiscuits were beautiful to behold, but when the boys came to samplethem they shouted. 

"Too much soda, Professor, " cried Tad. 

"No, baking powder, " corrected Ned. 

"Wow! I know what you're trying to do. You're trying to blow us up!"howled Stacy. "Why don't you use dynamite in the biscuit while youare about it? I think I'll go out and browse with the ponies. It'smuch safer and I'll bet will taste better. "

"Young man, if you don't like the cooking, you don't have to eat, youknow, " rebuked Professor Zepplin. 

"Yes, I do, too. What, not eat, and with an appetite like mine? Why, I'd eat my pistol holster if I couldn't get anything else. Speakingof eating that reminds me of a story---"

"Will some one please muzzle the fat boy?" begged Ned. 

"You can go out and hide in the bushes while I'm telling the story, "returned Chunky. "This is a nice ladylike story. It's about afellow---a clerk who was out with a party of surveyors, running aline across the desert. The water holes had gone dry and they werechoking for water when the clerk saved them and---"

"Ring the bell! Ring the bell!" shouted Ned Rector. 

"Yes, you have told us that story twice to my positive knowledge, "spoke up the professor. 

"Of course he has, " agreed Walter. "The clerk found water for themand they were saved, " added Tad, laughing immoderately. 

"Did he?" demanded Chunky eyeing them soulfully. 

"Yes, of course he did. You ought to remember the story. You havetold it often enough. "

"How did he save them?"

"He had a fountain pen, of course, silly! Have you forgotten your ownstory?" scoffed Tad. 

"He didn't have anything of the sort. This was another clerk. Thisone had a watch. "

Stacy glanced around expectantly. Not a face was smiling. All wereas solemn as owls. 

"He had a watch, " nodded Rector. 

"He had a watch, " added Tad. 

"I wonder if the watch was running?" piped Walter. 

"No, it was stagnant, " retorted Stacy. 

"Young gentlemen, for the sake of bringing a long-winded discussion toa close, I will offer myself as---as what you call a 'mark. ' What hadthe watch to do with their thirst?" asked the professor gazing sternlyat Stacy. 

The boys shouted. 

"Come down with the answer, Chunky. "

"The watch had a spring in it, " answered the fat boy solemnly. 

"I think it's going to snow, " observed Tad consulting the skiesreflectively. 

"Yes, the air is very chill, " returned Ned Rector solemnly. "Shouldn'tbe surprised if some one perished in this outfit. "

CHAPTER XV

MAKING A STARTLING DISCOVERY

Stacy Brown looked from one to the other of his companions in disgust. 

"Ho, ho! ho, ho!" he exploded. "Hard luck when a fellow's company isso thick that he has to laugh at his own jokes. Ho, ho, ho! Ha, ha, ha! It is to smile, but nobody smiles. You make me tired. "

"As I have already observed, I think it is going to rain, " said Tad. 

"Must be getting warmer, then. A minute ago you said it was going tosnow. It's my private opinion that you don't know what you think. Ned doesn't know any more. The professor is the only one in theoutfit who has a sense of humor. _He_ knows when it's time to laugh. Ha, ha!"

Professor Zepplin was smiling broadly. Stacy's joke was just dawningupon the professor. But Tad's mind at that juncture was in anotherdirection. The lad had raised his head in a listening attitude, hisglance fixed keenly on the other side of the camp ground. 

"Did you see something?" whispered Walter. 

Tad shook his head. 

"You heard something?"

"Never mind. Go on with the fun. Get Chunky to tell you when it istime to laugh. "

About this time Stacy got up, still chuckling to himself, and startedfor a cup of water. 

"Time to laugh. Ha, ha! What! Ha, ha; ho, h---"

The fat boy paused abruptly. He was down on his knees about to dipup a cupful of water when chancing to raise his eyes he saw somethingthat caused the word to die on his lips. 

A man stood just on the other side of the stream, lounging against atree, observing the fat boy with an amused smile. 

"Oh, wow!" howled the fat boy, in such a tone of alarm that the restof the outfit sprang up and ran toward him. "Wow! Look!"

At this juncture the stranger leaped the narrow stream and was standingbeside Stacy facing toward the camp when the others came up. 

"I suppose I should introduce myself before matters go any further, "smiled the newcomer. "I know you, but you do not know me. You arethe Pony Rider Boys. I am Captain Billy McKay of the Rangers. "

Stacy uttered a shrill laugh, whereat the captain shot an inquiringglance at him. 

"You---you are---are Captain McKay?" stammered Professor Zepplin. 

"Yes. I had hoped to see you when you camped with Lieutenant Withem---"

"Yes, we were with 'em, " muttered Stacy. "And I guess we've got 'emnow. "

"Unfortunately I was called away on that occasion. I promised myselfthat I should look you up at the first opportunity. I got on yourtrail this afternoon and as you were going in my direction I consideredthis an excellent opportunity to make your acquaintance. So here I am. "

"But---but---" stammered the professor. 

Tad was smiling, the others gazing at the newcomer blankly. 

"Well, sir, what is it? One would think you had seen a ghost, " laughedthe captain. 

"But, sir, you are the second man who has introduced himself to us asCaptain McKay of the Ranger troop, to-day. "

The captain's blue eyes twinkled. 

"Indeed! Then I must have a double. I should like to meet him. "

"You look like the real thing, " observed Stacy. 

"Thank you. Then the other man did not?"

"He did not---to me, " answered Tad Butler. 

"How are we to know that you are the captain in person?" asked theprofessor suspiciously. 

"I wear the badge and then here's my open countenance, " answered theRanger with another hearty laugh. 

"Professor, there can be no doubt that this is Captain McKay. I shouldknow him now from the description given to me by Lieutenant Withem. Won't you join us? We have just about finished the grub, but thereis more. I'll cook something for you, " proposed Tad. 

"I'll join you in a cup of coffee, thank you, " replied Captain McKay. 

"Lucky for him that Ned didn't make the coffee for supper, " mutteredStacy, but so low that the captain did not hear the remark. 

Captain McKay, the real Captain McKay this time, was almost boyish inappearance. He was of about the same build as the other man who haddeclared himself to be the captain, but the real captain had lighthair and laughing blue eyes, as opposed to the dark hair and eyes ofthe other man. The captain's skin was fair. It seemed not to havesuffered from exposure to the sun and storm of the plains. 

Tad led the way to the camp, followed by the visitor and the rest ofthe Pony Rider outfit. 

"Most remarkable, most remarkable, " muttered the professor, taking keensidelong glances at Captain McKay. 

"You are Butler, aren't you?" called the captain. 

"Yes, sir, " answered Tad, glancing back. 

"I knew you the instant I set eyes on you. You're a sharp young man. You discovered me before I got into your camp. "

"Discovered you?" exclaimed the professor. 

"Yes. He heard me. I stepped on a stick that bent down under my foot. The stick didn't snap and how that young scout ever caught the faintsound is more than I can explain. "

"So, that was what you were looking at?" laughed Ned. 

"Tad's got ears in the back of his head, " added Stacy. 

"I observe that all of you have pretty keen senses, " smiled the Rangercaptain. "Something smells good. "

"It's the coffee that Tad's making for you, " answered the fat boysolemnly. "How's the going?"

"Pretty fair. How is it with you?" returned the captain. 

"So, so, " answered Stacy carelessly. "You heard about my gettingshot, didn't you?"

"Oh, yes, I heard all about it. "

"I got wounded in the fracas, I did. I'm going to France one of thesedays to fight the Huns. Then I suppose I shall get shotted up somemore. You take it from me, though, I'll put some of those savages onthe run before they get me, " declared Chunky belligerently. 

"Perhaps you will explain why your men ran away from us the othernight, sir?" spoke up Walter. 

"They were called away. I guess the 'possum hunt was too much forthem, " answered the Ranger with twinkling eyes. "You rather put itover my boys, young man, " he said nodding at Stacy, whose face flusheda rosy red. 

"What's that?" demanded the professor. 

"Drove them out of their tent by unloading a bag of fleas on them. Ha, ha, ha! I guess you got revenge on them, young man. By the way, you're Brown, aren't you?"

"I was done brown down there in the bush that night. Mosquitoes wereworse than a volley of rifle bullets. "

"But---I don't understand, " protested the professor. 

Captain McKay laughingly explained. He told them how the Rangershad been so pestered by the fleas and other insects that Stacy hadcaptured in the 'possum bag that the men were forced to get up andwalk all the rest of the night, until a messenger had come from theircommander, ordering them to go on a hurry scout some forty miles fromwhere they were camped. 

The Pony Rider Boys laughed uproariously at this. Once more theysat down with a captain, but the same thought was in the mind ofeach---who was the first man who had passed as Captain McKay? McKayhimself did not appear to be over curious as to this. However, afterthe meal was finished he turned to the professor. 

"Now tell me about my double, " he said. 

"I don't know what to tell you except that he was about your age andbuild, dark hair and dark eyes, a very pleasant gentleman, I shouldsay. "

"Did behave a scar on his left ear lobe?"

"I must say that I did not notice. "

"Yes, he had, " spoke up Tad. "It looked as if he had been shot there. "

"Exactly, young man. You are very keen. I put a bullet through thatear myself, more than a year ago. I suppose you do not know who thegentleman is whom you entertained?"

"No, sir, " chorused the boys. 

"That, my friends, was the infamous Willie Jones, one of the mostdesperate characters on the Texas border. "

CHAPTER XVI

JOINING OUT WITH THE RANGERS

Exclamations of amazement greeted the announcement of the Ranger captain. 

"Willie Jones!" gasped the professor. 

"That is the man. You see what a sharp fellow he is. I suppose hepumped you gentlemen pretty thoroughly?"

"I guess he learned all he wanted to know, " replied Tad, flushing. "Idon't recall much of anything that he missed. "

Professor Zepplin wiped the perspiration from his forehead. 

"This is most disturbing, sir. I see now that Tad was right. Hecounseled caution. I gave no heed to his words of warning. "

"Master Tad is a very shrewd young man, Professor. I guess I shallhave to take him in with us. "

"Impossible! Impossible!"

"Why impossible?"

"I could not permit it. "

"Let me tell you something. Willie Jones now knows all about the partyou and your young men have played in capturing Dunk Tucker. He knowsthat it was your party that drove off his men when they were trying toget Lieutenant Withem. Do you think Willie will overlook that? NotWillie! Willie will be on your trail from now on. He will watch hisopportunity and when he thinks he is safe from the Rangers he willstrike---he or his men. Then you young men will need to beresourceful, indeed, if you get off with whole skins. "

"Oh, wow!" groaned Stacy. "I'll get it! I'll stop some more bullets. I'm the mark for all the lead that's flying around in these parts, I am!"

"I am of the opinion that we had better leave the border then, "declared the professor. 

"Oh, don't do that, don't do that, " begged the boys. "We never ranaway yet. Let's not do it now. We have taken care of ourselves beforethis and we can do so again. "

"Of course I do not wish to influence you. It is for you, Professor, to do what seems best to you. If you decide to remain I think I shallbe able to protect you. "

"What would you suggest, sir?"

"I was about to ask if you look to spend most of your time in themountains here?"

"That was our intention, later journeying down to the Rio Grande. "

Captain McKay nodded reflectively. 

"That will suit my plans very well. I have come to the conclusion, fromcertain things that have come under my notice, that the headquartersof this band of Border Bandits is here in the Guadalupes. Search aswe might we have been unable to locate their cache. "

"You mean where they hide?"

"Yes, that and something else. You see their plan of operation is this. These men indulge in various forms of rascality. In the first placethey steal stock when possible. This they drive over the border andexchange for Mexican goods, which they smuggle across the river andstore away until such time as they are able to dispose of it. Of coursethere are some people higher up who are receiving and disposing of thesegoods. We are on their track, but we haven't sufficient evidence toconvict any of them. The first thing to be done is to capture Jonesand his band. When they are safely behind the bars the traffic willstop short. Perhaps when we get them all in limbo one or another ofthe newer ones will confess. That will make our work easier. In factit is what we are depending upon at the present time. "

"I understand. But will there not be danger in our remaining here?"

"Perhaps. There's always more or less danger, and Jones will never letup on you until either he gets you or we get him. "

"I think I understand, " nodded Tad. "You think we shall be able toassist you?"

"Exactly. "

"Will you please explain?" begged Professor Zepplin. 

"You can help us a great deal, by remaining here. It is safe to supposethat the band will devote no little effort toward getting even with you. That means that they are quite likely to hover about in your vicinity. That will narrow down our field of operations considerably. We shan'tbe faraway from you at any stage of the game; in fact, I think it mightbe well to have two or three of our men in your party all the time. Doyou understand?"

"I begin to, " nodded the professor. 

"That will be fine, " answered Tad with glowing face. 

"Then we will be Rangers, too, " exclaimed Walter. 

"Yes, you will be Rangers, too, " laughed the captain. "You are prettygood rangers already. By assisting in rounding up these men you willbe serving your country, for, if we can put these Border Bandits outof business, we shall be destroying some of the Kaiser's worst troublemakers on the border. "

"And get shot full of holes, " added the fat boy. 

"That will do you good. It will give you an appetite, " jeered Rector. 

"He doesn't need a tonic, " spoke up Tad. "His appetite is quite enoughfor this outfit now. It's all we can do to keep enough supplies tokeep him going. My, it's an awful thing to have such an appetite. "

"Well, Professor, what do you say?"

"I am agreeable, if the boys are. "

"Hurrah!" shouted the Pony Rider Boys. 

"Of course, with the understanding, Captain, that you will see that weare properly protected?"

"You shall be. Of course there may be occasions when you will be goingon alone. You will expect that. Generally we shall be somewhere inthe vicinity. When we are all away it will mean that your enemies arealso away. "

"The man Tucker is safe behind the bars, is he not?"

"He was at last accounts, " smiled the captain. "I am sorry Jones knowswhat happened to Dunk. I had hoped to keep him in ignorance of thatuntil we had rounded up the rest of the gang. However, what's donecannot be undone. "

"Where is your horse?" asked Tad. 

"A little way down the creek. He's all right. Don't worry abouthim. "

"By the way, when shall we see your men?" asked the professor. 

"You should see some of them soon now. They know where I am, and ahalf dozen or so will be riding this way before morning, I think. "

"You will remain with us to-night, of course?" urged Tad. 

"If you insist, " smiled the Ranger captain. 

"Certainly we insist, " emphasized the professor. 

"Of course we do, " added Chunky. "Maybe if there are any bulletsflying about you will stop them instead of my doing it. I'm tired ofstopping bullets. It hurts. "

"Having stopped a few in my time I think I know all about it, young man. "

They could not believe that this sunny-tempered, soft-spoken youngfellow was the most dreaded of all the officers of the law who hunteddown the desperadoes of the border. It was also difficult to believethat Captain McKay was a marked man who had been condemned to death bythese same desperate characters. Something of the resourcefulness ofthe man was shown to the boys in a most marked manner later in theevening. 

All hands had been sitting about the fire, the boys trying to draw outCaptain McKay to tell of his experiences, which the Ranger was lothto do. What experiences he did tell them were such as chieflyconcerned others than himself. According to his version Captain McKayhad played a most inconspicuous part in the splendid work of theTexas Rangers. Not once did he refer to the fact that he was theterror of every evil-doer in the State of Texas. 

Finally it came time to turn in for the night. The captain lazilyrose and stretched himself. The others were still seated, but werepreparing to rise and prepare for bed when the interruption came. 

A flash and a report from the bushes toward which the Ranger's back wasturned caused every one of the boys to jump. Tad had his wits about him. 

"Down!" he commanded. 

"Oh, wow! There it goes again, " moaned Stacy. "They're shootingat me again!"

Professor Zepplin had rolled into a depression in the ground, thusconcealing his body from the unseen shooter. But in the meantimeCaptain. McKay had not been inactive. It seemed as if the bullet thathad been fired at him from the bushes had barely shrieked past his ear, when the captain wheeled. His revolver---two of them---had appearedin his hands as if by magic. 

Bang, bang! crashed the captain's weapons as he whirled. A yellsounded off there. Captain McKay dashed toward the spot, followedby Tad on the jump. 

"Stay back!" shouted the Ranger, but Tad did not obey. He proposedto have a share in whatever trouble was before the brave Rangercaptain. Chunky had taken to the bush. The others were lying flaton the ground. 

As the captain ran he let go two more shots. This time there was noanswering yell from the bushes. But he distinctly heard a crashingin there and drove in two more shots. He charged the bushes utterlyregardless of the peril to himself, with Tad Butler close behind him. Tad had his revolver in hand, but he was cool headed enough not toindulge in any indiscriminate firing. 

It was evident that either more than one man had been in the attackingparty or else one who had been wounded had not been badly enough hurtto prevent his getting away. Not a sign of a human being was theRanger able to find, though his keen eyes soon picked up the trail. He followed it a short distance, finally having reached soft ground, getting down on his knees and examining it critically. 

When he looked up he found Tad standing over him. 

"I thought I told you to stay back, young man?" he said sharply. 

"I don't like to stay back when there's anything going on. What doyou find?"

"There were two of them. Here's where they mounted their ponies. Iwish I knew who they are. You see those fellows are watching. "

"Watching you?"

"No. They came here to clean out the Pony Rider Boys, I reckon, "laughed the Ranger. "They didn't expect to find me here. But whenthey saw me they couldn't let the opportunity go without taking a potshot at me. I moved---I stretched---just at the right second, or I'dhave been a dead man before now. "

"The cowards!" breathed Tad, his eyes glowing angrily. 

"Oh, yes, they're all of that. They shoot when the other fellow isn'tlooking, and they shoot to kill. But we might as well go back. Icould follow them, but it hardly is worth while. They will be hiddenlong before we can run them down. They'll leave a blind trail prettysoon after they get far enough away to make it safe for them to stopand cover their tracks. "

"But, will they not come back again?" urged Butler. 

"Not to-night. They know I am on my guard now. They will put offtheir attack on you until some other time. Lucky I chanced to be herewhen they first came. I hope they don't take the alarm and keep awayfrom you now. "

Butler grinned. He hoped so too, though the others of his party mightnot share this hope with him, especially Professor Zepplin who wasgetting rather more excitement out of this journey than he had lookedfor. 

By the time the two had returned to the campfire the others had musteredcourage enough to stand up. The professor, his whiskers bristling, hadcrawled from the depression into which he had rolled at the first signof trouble, and Chunky was making his way cautiously from the bushes. 

"Captain McKay, how much of this sort of thing shall we have to face?"demanded the professor. 

"You might have had to face a good deal more of it, had I not been here, "answered the Ranger shortly. 

"What do you mean?"

"That had I not been here you would have got the bullets fired at me. As I have already said to Butler, those men were after your party. When they saw me they knew they would not dare to waste a shot on anyone else. "

"While they were shooting you up, they knew my arsenal would get intoaction. They figured on killing me the first shot. But they didn't, "added the captain with a mirthless grin. 

"I don't like this at all, " declared Professor Zepplin with a slowshake of the head. 

"Neither do I, " agreed Chunky. "I'd as soon be shot to death as scaredto death. I'll bet my hair is turning gray already. Oh, wow!"

"All hands, turn in, " commanded the Ranger briskly. "I will stand watchover the camp for the rest of the night, though you will not bedisturbed. "

CHAPTER XVII

FUN ON THE MOUNTAIN TRAILS

Confident in the watchfulness of Captain McKay the Pony Rider Boys sleptsoundly all through that night. Even Chunky forgot to talk in hissleep, thus saving himself from sundry digs in the ribs from hiscompanions. 

But when the morning came again the lads were treated to still anothersurprise. Captain McKay was sleeping in front of their tent door, rolled in his blanket, using one arm for a pillow. Still further outlay three other men, with one sitting up. The latter was none otherthan Dippy Orell, one of the Rangers. A second glance showed the boysthat the other three men were also of the Ranger band. 

"Hullo, Bugs, " greeted Dippy upon catching sight of the fat boy. 

"Hullo. You here?" demanded Stacy. 

"I'm here, what's left of me. "

"Bring any 'possum for breakfast?" grinned Chunky. 

"No, but I've a rod in pickle for you. "

"All right. Keep it in pickle for yourself. I don't like sour stuff. "

"Hey, there, Bugs!" greeted another Ranger sitting up. 

"My name's Brown, " Stacy informed him with dignity. "When did youcome in?"

"We blew in with the dawn, " answered Dippy. 

"And we're going to blow out with the sun, " added Polly Perkins. 

"Say, Kid, " growled Cad Morgan, rubbing his eyes sleepily as he satup blinking. 

"His name is Bugs, " interrupted Dippy. 

"All right. Say, Bugs, I've got some news for you. "

"I don't care about any news you've got to give out It's probably gota bullet in it somewhere. I'm sick of bullets. What I need is alittle rest from chunks of lead. I'm coming down with nervousprostration as it is. Everything seems to happen around me. Nomatter what I do, I always get the worst of it. Why, that remindsme---"

"Is Chunky going to tell a story?" cried Ned, stepping over the sleepingcaptain as he came out. 

"It sounds that way, " laughed Tad. "Go on the Rangers are here toprotect us if you tell another watch story. I reckon they'll arrestyou if you try anything like that on them. "

"As I was saying that reminds me of a couple of years ago when my unclebought a lawn mower because the grass was getting so long in our frontyard that the cats couldn't chew it---"

"Cats chew it?" jeered Dippy. 

"Yes, before a rainstorm. They always do. "

"Go on, go on. I'm pretty tough, " urged Polly. "But don't drive metoo far or I'll buck. "

"As I was about to say---"

"You said that once before. "

"I offered to run the lawn mower. Uncle thought that was fine. Yousee work and I never had hitched very well together. But I thoughtthat would be some fun. So I started in mowing the yard the nextmorning, " finished Chunky thoughtfully. 

"Well, what happened?"

"Would you believe it, be---before I'd been at work half an hour, the town constable came up and arrested me for exceeding the speedlimit. Now---now wasn't that hard luck?"

The Rangers gazed at each other hopelessly. No one laughed, thoughWalter Perkins was heard to chuckle under his breath. 

"If it might be proper, I reckon I'd like to ask what being arrestedfor exceeding the speed limit has got to do with catching bugs in a'possum bag?" demanded Dippy Orell. 

"Why---why---the---the constable came up in a buggy, don't you see?Ha, ha. Don't laugh. It might hurt your countenance. I'm used tolaughing at my own jokes and---"

"Hee---haw, hee---haw!" wheezed Polly in imitation of a donkey. "What'dwe better do with him, fellows?"

"I reckon I'd better tell him the news I was going to, " answered Morgan. 

"I reckon that'll take the starch out of him right smart, " nodded Polly. 

"Dunk Tucker has got away, Bugs. "

"Em" Chunky was interested at once. 

"Don't make me say it so many times. It hurts me. I said that DunkTucker has got away. He 'busted' out of the calaboose over at ElPaso some time yesterday morning and he's on the warpath. "

"G---g---g---got away?" gasped Chunky. 

"Yep, and he's heading in this direction to get even with you fellowsfor taking him up. What d'ye think of that, Bugs?"

"Oh, help!" groaned the fat boy. 

"Is this right?" questioned Tad. "Has Tucker really escaped?"

The Rangers nodded. 

"That's what we're here for, to catch him up when he makes connectionswith his crowd again. I reckon he'll be on the trail of this outfit, first of all, before he joins out with his own outfit. He'll neverrest till he puts a bunk of cold lead under the skins of the fellowswho got him. "

"This is where I---I get shot again, " wailed Stacy. "I knew it. I knewsomething else would come along to spoil all my fun!"

"No use trying to sleep in this bedlam, " cried Captain McKay springingto his feet. "Saddle up. I want to make the Ten-Mile cross-trailbefore noon. We'll find two men waiting there for orders. Professor, can you get under way at once?"

"Of course we can, " answered Tad for the professor. 

"Don't we get any breakfast?" cried Chunky. 

"Yes, but you'll eat it cold this morning. "

"Oh, pooh!"

"If you are going to be a Ranger you must be willing to take a Ranger'sfare, " smiled the captain. 

"I haven't said I wanted to be a Ranger. I don't. I want to be apeaceful citizen. "

"With four square meals a day and a whole pie thrown in, " suggested Tad. 

"Something like that, " smiled Stacy. 

The tent was already coming down. The Pony Rider Boys showed theRangers that they were used to quick work. Twenty minutes later theboys were ready. The Rangers had watched their preparations withinterest. 

"Good work, " said Captain McKay approvingly. 

"Anybody'd think you had traveled with a one-hoss circus, " grinnedDippy. 

"We've got some of the animals left yet, " laughed Tad. 

"The Fattest Boy on Earth and---" began Polly when Chunky shied a tentstake at the head of the Ranger, thus sharply ending the discussion. A few moments later they were on their way. The boys had to riderather fast to keep up with their escort, for the Rangers were rapidriders under all circumstances. A great deal of their success was dueto their ability to cover long distances between daylight and dawn orsunrise and sunset, appearing in localities where they were not inthe least expected. In this way they had been enabled to make manyimportant captures. But the riders did not move so rapidly in thisinstance that they were not able to poke fun at the fat boy. Stacywas the butt of almost every joke. 

To all of this Stacy Brown did not give very much heed. He wasplanning how he could turn the tables on the Rangers again, amusinghimself with whistling, making queer noises in his throat, tryingto imitate birds that he passed. 

But all at once there came a sudden end to his practice. Stacy's ponysuddenly leaped to one side, planting its front feet firmly on theground and arching its back like an angry cat at bay. Stacy did abeautiful curve in the air, landing on his shoulders on the hardground. He had a narrow escape from breaking his neck. 

The Rangers howled. They were still bowling when Stacy, getting hisbreath back, sat up, bunching his shoulders to get the kink out ofthem, and rubbing himself gingerly. The pony stood looking at itsyoung master sheepishly. 

"What's the trouble, Stacy?" cried Tad riding back. 

"I---I fell off. "

"I know you did. There couldn't be any mistake about that, but whatcaused him to throw you?"

"I---I don't know. "

"That pony was frightened at something. What was it?" demanded thecaptain of Cad Morgan. 

"I'm blest if I know, Captain. There wasn't anything that I saw. "

"Take a scout around through the brush, you and Polly. There may besome one taking a parallel trail. "

"Yes, there may be some German raiders hiding out there in the bush, laying for us. We ought to have some bombs. They would clean thosefellows out in short order, " declared Stacy. 

The two men trotted from the line and disappeared among the trees, while the fat boy got back in his saddle, somewhat more sad, but nowiser than before. But he was thinking a great deal. 

"He must have got scared at some of my imitations, " decided the lad. "I don't blame him. "

"But which one was it? I'll see if I can do them again. "

Letting his horse drop back a few rods behind the others, Chunky wentover his list of accomplishments in the imitation line, trying eachone cautiously, keeping a watchful eye on the ears of the pony. 

All at once the eyes of the fat boy lighted up. Something struckhim as funny. He laughed aloud. 

"Chunky's got them again, " chuckled Ned Rector. 

Stacy waited until all hands were looking ahead when he tried theimitation that he believed had caused his mount to halt. His successwas instantaneous. The pony leaped clear of the ground, coming downwith a jolt that made the boy's head ache. 

"What's the matter with that horse?" called Captain McKay. 

"Guess he's feeling his oats, " flung back Chunky. The boy huggedhimself delightedly. What he had done was to give a trilling tonguemovement accompanied by a hiss. It was a perfect imitation of thetrilling hiss of the rattlesnake. When Stacy had first given theimitation he did not realize what he was doing. He had fooled hispony. The Pony Rider Boy was delighted. He tried it again withequal success, though this time he was thrown forward on the neck ofhis mount. This jolt nearly broke Stacy Brown in two. 

"That was the blow that near killed papa, " grinned the lad. "I neverknew I could do that. I reckon. I'll be having some fun with thisoutfit. Yes, I'll try it on right now. "

Stacy spurred his pony close up to the leaders. The lad's face wassolemn, but it shone like an Eskimo's after a full meal of blubber. Ned Rector was next ahead of the fat boy. Chunky pretended not tosee Rector. Riding close up to him, the fat boy softly gave hisrattlesnake imitation. 

Ned Rector made a high dive, landing head first in a thicket ofmesquite brush, while his pony was left kicking and bucking on thetrail. Stacy was having more trouble with his own pony. 

"Whoa, there, you fool! Whoa! What's got into this beastly pinto?"howled the fat boy. 

"That's what I'd like to know too, " snapped the captain, wheeling hishorse, giving the fat boy a quick, sharp glance. 

Ned, having picked himself out of the mesquite bush, was limping back. 

"You hit him, Stacy Brown!" shouted Rector. 

"I never touched him. What's the matter with you?" protested Chunkyindignantly. 

"No quarreling, boys, " warned the professor. 

"Well, he doesn't want to be poking my pony!"

"Well, he doesn't want to be accusing me of poking his old bundle ofbones. "

"Pretty lively critter for a bundle of bones, I should say, " answeredthe captain grimly. 

"Nobody trailing, " announced the scouts returning a few minutes later. The captain may have had a suspicion, but if so he kept it to himself, making no reply to the report of his two scouts. 

For reasons best known to himself Stacy did not give his rattlesnakeimitation again. But every little while a broad grin would grow onhis countenance, which the fat boy would suppress as quickly aspossible. 

"This is too good a thing to be nipped in the bud, " he muttered. "No, sir, I don't give my secrets away yet awhile. Mebby I never shall. "

Stacy well knew that swift punishment would be meted out to him if theothers caught him at his new trick, so the fat boy kept silent, lookingthe picture of innocence. 

CHAPTER XVIII

ONE HISS TOO MANY

The Ten-Mile cross trail was made about half past one o'clock in theafternoon. Walter Perkins entered the camp on his head, Tad Butlerhanging to the mane of his bucking pony, both feet out of thestirrups, Stacy Brown making desperate efforts to quiet his own mount. 

The ponies had heard the soft hiss of a rattlesnake, but the ears ofRangers and Pony Riders had failed to catch the sound. Perhaps it wasthe yell that the fat boy had uttered instantly after giving theimitation that had too suddenly attracted the attention of the party. 

"What's the matter with those fool cayuses?" shouted Dippy Orell. "What---"

Dippy did not finish his remark. He landed on his back thoroughlyshaken down. He was up with a roar, starting for the pony with bloodin his eye. 

"That'll do, Dippy!" commanded the leader sternly. "If you'd beenriding as you should have, you never would have fallen off. Nowyou're off, stay off. " The captain uttered a bird-call which wasanswered in kind. The boys understood at once that the Rangers wereexchanging signals. A few moments later, a bronzed, weather-beatenRanger rode into camp. He held a few moments' conversation with thecaptain, after which he rode away. 

"Anything doing, Cap?" asked Morgan. 

The leader shook his head. 

"Something may turn our way to-night. Joe has been detained. I don'tknow what is keeping him. But we'll wait here till he comes in. Professor, it is possible that we may have to make a hard night rideto-night. Do you wish to go along?"

"Of course we do!" shouted the boys. "We don't want to miss a singlething. "

"No, we don't want to miss a thing, " agreed Chunky solemnly. "I seeI've been missing a great deal lately. I don't propose to miss anotherthing as long as I'm out on this cruise. "

"He thinks he's on a canal boat, " jeered Dippy. 

"Maybe if I do it's because we've got some mules to pull it, " retortedStacy. 

"Ouch! But that one landed below the belt!" exclaimed Dippy. 

"Our fat friend has a sharp tongue, " observed Polly. 

"I guess we'll have to file it. Might hurt himself on it if he happenedto stumble over a root and fall, " added Cad Morgan. 

"Chunky, are you going to get busy and help settle this camp?" demandedTad. 

"I don't have to work. I'm a guest of the management, " answered Stacy. 

"The management disowns you. You're out in the cold world, " laughedButler. 

"All right. That's good. Then I don't have to work. "

"No, he doesn't have to work, " agreed the professor. "Nor does hehave to eat. No work, no eat, is the motto of this outfit. "

Chunky got busy at once. Captain McKay had little to say. He wasvery thoughtful, evidently perplexed by some word that his scout hadbrought him. The other men made no further effort to learn what wasdisturbing their chief. They knew he would tell them if he wantedthem to know. At McKay's suggestion, nothing was unpacked save thestuff necessary for their meal. Of course all the packs were removedfrom the ponies to give the little animals a rest. The poniesapparently had ceased from their tantrums and were as docile as ifthey had never known what it was to buck off a rider. 

Polly was getting the dinner while Tad and Ned were starting and keepingup the fire. The others occupied themselves with various duties aboutthe camp, all save the captain who sat on a rock some little distancefrom the scene of operations. 

Suddenly Captain McKay leaped from the rock, taking a long spring awayfrom it, at the same time drawing a revolver and whirling. Chunky, whowas passing at the time, was bowled over by the captain's sudden spring. 

"Look out for the rattler!" commanded the Ranger sharply. 

"Oh, wow!" howled Chunky springing back apparently in great terror. "Snake, snake!" he cried waving his arms to the others near thecampfire. "Look out for the snake!"

McKay saw no snake to shoot at. Deciding that the reptile must havesquirmed away, the captain, his face wearing a sheepish smile, shovedhis weapons back into their holsters and strode back to the camp, where Stacy had preceded him. 

There were no further indications of the presence of rattlers, andin a few moments the adventure was wholly forgotten. Shortly afterdinner the captain sent his men out on a long scouting expedition, himself riding from the camp, taking Tad Butler with him. Tad wasproud to be thus singled out. While they were on their ride, sometwelve miles to the southward, the Ranger captain taught the northernlad many things about trailing human beings. This was all new to Tad. He listened with rapt attention, though he hoped it never might fallto his lot to have to trail men for a livelihood. The captain alsotold him many things about the bad men of the Texas border in theold days. Captain McKay was a lad then, but he was out with hisfather much of the time, the father also having been a Ranger, havingbeen killed in a battle with a desperado whom he had been sent tocapture. Captain McKay's two brothers had shared a similar fate. Now there remained only Captain Billy. 

"And I expect one of them will get me one of these days, " he concludedsteadily. 

"Why not stop then before they do get you?" questioned Tad. 

"A fellow's got to die some time, hasn't he?"

"I suppose so. "

"And he won't die till his time comes, will he?"

"I couldn't say as to that, sir. I guess we are not supposed to knowabout those things here on earth. "

"No, a fellow doesn't go till his time's come, " answered the Rangerwith emphasis. "So what's the use in dodging? Why, if my time hadcome and I had quit and gone to the city to live I'd most likely be runover by a trolley car or something of that nature. I'd a sight ratherdie in a gun fight with a real man than to get bucked over by a hunkof wood and iron and lightning, called a trolley car. No, I'll takemy medicine, as I always have and---But let's go back. "

"Still it is no worse than fighting the Germans, " observed Tad. "Ihave wondered why you have not enlisted and gone to France, you andyour men? What splendid fighters you would make. "

"Every man of them wants to go---I want to go. I can hardly holdmyself down, Kid. Every one of us has offered his services, but thegovernment would not hear to it. Because of the activity of theKaiser's agents in Mexico and on the border, Uncle Sam decided that wecould best serve him right here on the border, and here we are, "answered the Ranger thoughtfully. 

"Have you found what you came out here for?" asked Butler. 

"Surely I have, " smiled the captain. "Haven't you?"

"I haven't found much of anything unless you mean that a couple ofhorsemen crossed back there some few hours ago. "

"How'd you know that?" exploded the captain. 

"I saw the trail they left. "

"Shake!" cried the captain leaning from his saddle. "You're thealfiredest sharp youngster I've ever come up with. Oh, it's too badthat you have to waste your talents in a city! Too bad, too bad!You ought to be out here on the plains and in the mountains whereone's manhood counts for something. "

"Did you come out to pick up that trail, sir?"

"That's what I came for, my boy. I reckoned those two fellows who gotafter us in camp last night would take this trail and head for thelower end of the mountain range. That's what they've done. Thistrail proves that. Of course they may get sidetracked, but that'stheir idea up to this point. I think we are safe in following ouroriginal plans now. "

Captain Billy did not say what those plans were, nor did Tad ask him. They now turned about and started toward home at a slow jog trot, riding side by side where the trail permitted and in single filewhere it did not. 

On the way back the captain asked Tad many questions about himself, the members of his party and their experiences during their variousjourneyings into the wilder parts of their native land. 

"Ever think of joining the army yourself, Tad?" questioned the Ranger. 

"Have I? I am thinking of it most of the time. Oh how I wish I wereold enough. I know I could give my country good services now. "

"You bet you could, Kid. You would make a wonderful scout over there, "declared the captain, nodding. 

"Some day, if the war lasts, I shall go, " asserted Tad in a low voice, tense with emotion. 

Billy said he had been East to Chicago once, where he had been robbedof everything he had on except his clothes. 

"Funny, isn't it? I'd like to see a fellow go through me out here inmy native pastures. But back there in the city---" Billy shook hishead. The subject was too great for words. 

They found the camp quiet and in order. The three boys and theprofessor had been sleeping a good part of the afternoon, and withouthaving put out a guard, either. The captain shook his head, glancingsignificantly at Tad as he heard this. In fact the two had to shoutto awaken the party. Then to learn that they had been sleeping allday---well, there was nothing to be said. 

"Do we move to-night, sir?" asked the professor. 

"Can't tell you. Not until I hear the reports of my men, and themessenger or scout whom I looked for to meet us here at noon. Seen. Anything of that rattler around these diggings, Professor?"

"No, we haven't seen any rattler. "

"We don't want to see any rattler, " piped Chunky. "I'd snip his headoff with my pistol if I caught sight of him. "

"Yes, you would!" grinned Tad. 

"You'd have to learn to shoot first, " scoffed Rector. 

"Perhaps Captain McKay will give us some lessons in revolver shooting, "suggested Tad. 

"From what I hear I guess you boys are pretty handy with both rifle andpistol as it is. However, if there are any drawing or sighting tricksI can show you I'll be glad to do so. "

"Thank you. If we are where it is safe we will ask you to make goodthat promise to-morrow, " declared Tad Butler. 

While they were preparing the supper that night the Rangers whom thecaptain had sent out on a scouting expedition rode into camp, tiredand gloomy. It was a personal and keen disappointment to every man ofthem that some ruffian hadn't shot at him once during the ride. Notonce had the Rangers' weapons been out of their holsters. Whatevertheir mission the men merely shook their heads in reply to aquestioning glance from their commander. That was all. No wordswere wasted in explanations. The captain knew that his men had donetheir work thoroughly. No explanations were necessary. This perfectconfidence and understanding between commander and men was not loston Tad Butler. It was an object lesson that made a deep impressionon him. 

The men had returned with sharp edges on their appetites, but they atein silence. Stacy had little to say at dinner. He was observing theRangers with wide eyes, stuffing his cheeks with food and listeningwhile the professor, Tad Butler and Captain McKay discussed a varietyof subjects. 

"I don't understand why Joe hasn't come in, boys, " said the captainfinally. "He had passed Tonka Gulch at four o'clock this afternoon. He should have arrived here a long time ago. "

The men nodded. 

"Perhaps he's come up with Withem, " suggested Cad Morgan. 

"I don't think so. The lieutenant isn't due there until some timeto-morrow. He will have to finish investigating the El Paso end beforehe can come along and join up with us. "

Tad wondered how the captain knew that his scout had reached a certainpoint in the mountains when none had seen him or heard from him. Butthere were many mysteries connected with the work of these brave men. They worked in mysterious ways that added to the awe in which theywere held by those whose ways were dark. 

The night was warm and soon after supper the Rangers threw themselvesdown on the ground wrapped in their blankets. In view of the fact thatthe whole party might be called out all turned in early. The men hadbarely closed their eyes when suddenly there sounded the menacing hissof a rattler right among them. 

"Look out!" yelled Polly, jumping up. 

"What is it?" cried half a dozen voices, as their owners sprang upwith drawn weapons. 

"There's a rattler in camp. Get a torch, somebody!"

Tad, who had snatched an ember from the dying campfire, was poking aboutcautiously, the torch in one hand, a club in the other ready todispatch the reptile on sight. The Ranger who had been on guard dutyhurried in upon hearing the uproar. He said he had heard a snake justafter leaving the camp. The men jeered when they saw Stacy half way upa small tree, peering down at them with scared eyes. 

"Afraid of the snake, eh, Bugs?"

"No, I'm not afraid of any snake. I just thought I'd get out of yourway so you could work better. "

The men jeered again. Morgan stepped over and gave the tree a shake, whereat the fat boy came sliding down to the ground. The search forthe reptile was a fruitless one. After a time the Rangers turned inagain. They had not been rolled in their blankets more than fiveminutes when that same fearsome, trilling hiss smote their ears again. This time the men were mad. They declared they'd find the "pizencritter" before ever they turned in again. 

"Pile on some wood. We've got to have light here, " ordered the captain. "Where was he?"

"That's what we're trying to find out, Captain. It isn't any easymatter to locate a sound like that. The critter may be 'most anywhere. "

"Have---have you looked in your pockets?" stammered Stacy. 

"Yes, maybe he's crawled in your clothes to get warm, " grinned Tad. 

"Oh, close up!" growled a tired Ranger. 

"I was just trying to help you, " answered Chunky indignantly. "Youneedn't get mad about it. "

"No, don't grouch, " laughed the captain. "We are losing too much timeas it is. Better roll in your blankets and go to sleep. The firewill drive the fellow away. "

Some of the men tried to sleep standing, leaning against trees. Otherstook the chance and rolled in their blankets. But there was littlerest in the camp that night. About the time the men had settled down, they would be awakened to their surroundings by that same trilling hiss. It was beginning to get on the nerves of the Rangers. They were gettingmad. The Pony Rider Boys felt a sense of discomfort too, though noneshowed any nervousness. It was not the first time the young explorershad passed through such an experience. Just the same they would havepreferred to be in some other locality just then. 

Finally Stacy went to sleep. When he woke up with a start, he triedto recall what had been going on when he dropped off. Then heremembered. He had been indulging in his famous imitation of an angryserpent. Had any of the men been awake at the moment he might haveseen the fat boy's blanket shaking as if the boy were sobbing. ButStacy Brown was not sobbing. 

It was some moments before he had subdued his merriment sufficientlyto hiss again. The hiss was unheard. Stacy opened his eyes as he sawthe captain striding into camp. He saw McKay awaken the Rangers, thenstart to arouse the Pony Rider Boys. In his wonderment at theproceeding Stacy forgot to hiss again for some time. 

"Saddle up, " commanded the captain sharply, but in a low tone. 

The camp, so silent a few moments before, was now a scene of orderlyactivity. Every man in it was packing his pony and in less than tenminutes after the alarm had been given the men were in their saddles. The Pony Rider Boys were full of anticipation. It looked to them asif something were going to develop that was worth while. 

Starting off in single file the men dozed in their saddles, but thePony Rider Boys did not. The latter were too much excited for sleep. All at once that trilling hiss came again. Two dozing Rangers landedon their backs in the bush. The party was in an uproar, but assuddenly quieted by a stern word from the captain. The latter wonderedat their being followed by a rattler. It was peculiar to say the least. 

Stacy hissed again. Then the boy shivered, for a heavy hand was laidon his arm, closing over it until the fat boy yelled. 

"Ouch! Let go of my arm!" he cried. 

"Young man, I think I've got the rattler this time, " said the sternvoice of Captain Billy McKay, as the fat boy fairly shrank withinhimself. 

CHAPTER XIX

SURROUNDING THE ENEMY

"What's that?" roared Dippy. 

"Here's your rattler. I've been suspecting him ever since early inthe evening. This young man has been imitating a rattler's hiss andI must say he did it mighty well. "

"What's that? 'Bugs' been causing us all this trouble?" demanded Dippy. "Let me at him! Let me at him!"

"Here, take him, but don't make too much noise about it, " grinned theRanger captain. "And don't be too rough about it, either. "

Dippy had Stacy by the collar. With a powerful hand he jerked the fatboy across his saddle and such a spanking as Stacy Brown got thatnight he had not had since he was considerably younger. The otherRangers clamored for a chance at him, but after Dippy had finishedthe captain decided that the fat boy had had enough. There wasstern business on hand. Still McKay thought a lesson might not comeamiss at that time, so he had permitted the little diversion. 

Growling and threatening, Stacy was dropped back into his saddle. 

"Remember, we haven't had our turn yet, " warned Cad Morgan. "Remember, you've spoiled a few hours of sleep for us fellows. "

"Yes and re---re---remember you made me stand in the mesquite bushfor three hours waiting for the 'possum to jump into the bag, "reminded Stacy. "I guess we are about even now. But, if you wantsome more trouble, I'll think some up for you. If I can't think itout alone Tad will help me. "

"I don't believe you need any assistance, " laughed the captain. "Nomore disturbance now. Gentlemen, I am going to divide up our party. The time has arrived for me to tell you my plans. I have receivedinformation from one of my scouts that some half dozen of the men wewant are heading for a point yonder in the mountains. They are torendezvous at a place about three miles from here where they are tomeet others of their outfit. It is my intention to surround them. One of my men is now on their trail, following them as closely aspossible. There may be some shooting. If any of you wish to stayback you may go into camp right here and we will pick you up later. "

"No, no! Take us along, " begged the boys. "We don't want to be leftbehind. How about you, Chunky?" called Tad. 

"No, I don't want to be left. I---I guess I'd be afraid to stay hereall alone. "

The captain quickly disposed of his forces, directing Tad Butlerto come with him. Upon. Second thought he decided to take Stacyalong also, perhaps believing that it would be safer to have thefat boy under his own eyes, as there was no telling what Chunkymight otherwise do. 

The party broke up, leaving the spot in twos, after having receivedtheir orders, but in each case the Pony Rider Boys were accompaniedby one or more of the regulars. 

In a few minutes all had left the place, except McKay, Tad and Stacy. These waited for the better part of half an hour. 

"Now forward and no loud talking, boys, " the captain directed, touchinghis pony's sides with the spurs. "Be ready to obey orders quickly. And, Brown, no more imitations on your part. This is serious business. A slip and you're likely to stop a bullet 'most any time. "

The three men started away, with the captain in the lead. Theytraveled all of two miles when McKay called a halt. 

"Butler, you will go to the right, straight ahead. Stop after youhave gone about a quarter of a mile as nearly as you can judge. Whenyou hear an owl hoot, move slowly forward. Don't use your gun, nomatter what happens, unless some one shoots at you. Even then don'tshoot unless you have to. But let no one get past you. We hope toget those fellows in a pocket and hold them up without any shooting. But we may have to waste some powder. Do you understand?"

"Yes, sir. "

"You are not afraid?"

"I am not. "

"I thought you wouldn't be. "

"Where do I go?" asked Stacy apprehensively. 

"You will remain with me. I'll take care of you. All right, Butler. "

Tad without another word rode away. Finally after having gone whathe thought was the proper distance, he halted and sat his pony silently, head bent forward listening for the signal. It came at last, soundingfaint and far away. The boy smiled, shook out his reins and the ponymoved forward almost as silently as the boy could have done himself. The night was dark, but Tad was able to make out objects with more orless distinctness. He used his eyes and ears to good purpose. OnceTad thought he heard a twig snap a short distance ahead of him. Hehalted abruptly and sat steadily for fully ten minutes. There beingno further sounds he moved forward again. 

It was a trying situation for a boy. Tad Butler felt the thrill ofthe moment, but he was unafraid. It is doubtful if Tad ever hadrealized a sense of fear, though he was far from being foolhardy, nor was there the faintest trace of bravado about him. He was simplya steady nerved, brave lad who would do his duty as he saw it nomatter how great the obstacles or how imminent the peril. 

The boy had gone forward for some thirty minutes when all at once hisquick ears caught a peculiar, low whistle some distance ahead. Tadwith ready resourcefulness answered the whistle, imitating it asnearly as possible. But he made a mistake. That whistle was notthe right whistle. 

Bang!

A flash of flame leaped toward him and he heard the "wo-o-o-o" of abullet over his head. The boy was off his pony. Then Tad tried thetactics of an Indian. Quickly and silently tethering his pony, hefired a shot high enough so that he did not think it likely to hitany one. Skulking a few paces farther on, he fired again. Severalshots were in this manner fired, and in quick succession, giving theimpression that there were several men shooting. 

Half a dozen answering shots were fired at him, then the lad caughtthe sound of hoofbeats. He knew the other man was riding away. Tadgave the hoot of an owl as best he could. Rather to his surprise thesignal was answered off to the left. Tad repeated it and received thesame answer. He rode forward, on the trail of the fleeing man. In afew minutes he was joined by Captain McKay and Stacy, both riding hard. 

"Did you draw them out?" demanded the captain sharply, but without atrace of excitement in his tone. 

"Yes. " Tad explained what had occurred. 

"That was one of the outposts. The others will begin to stir soon. We are too early. All the ruffians are not in yet. Well, it's toolate now. The alarm has been given. There they go!"

A succession of shots followed from distant points, widely separated. McKay listened. 

"Our men are shooting. It's time to close in. Stick behind me. Don'ttry to ride off to one side. Keep your eyes and ears open. "

The ponies leaped forward. The man and the two boys were riding adangerous pace considering the roughness of the trail, but none gavea thought to the danger. The captain's voice was raised in along-drawn hoot, which was answered by another from some distance away. Then the firing broke out afresh. It seemed as if no one could escapethat fusillade of bullets. Tad could hear the bullets screamingoverhead. He sat his pony, his eyes glowing, firing rapidly into theair. Stacy Brown also sat his own pony, but he couldn't have moved amuscle to save him. The fat boy was literally "scared stiff. " Stacyreally was suffering, but no one, unless he had observed his eyes, would have thought him afraid. 

"Close in, boys. Ride and shout!" commanded the captain. 

Butler exercised his lungs. Chunky's lips moved, but no sound camefrom them. His pony, however, followed the others, nearly causingits stiffened rider to fall off. 

Every few moments the captain would utter his owl-call, which wouldbe answered by other similar calls pretty much all around the compass. In this way the Rangers were able to locate each other's positions, thus avoiding shooting each other. 

The shots of the enemy were now scattering. 

It was only occasionally that McKay was able to determine that one ofthe bandits had fired a gun. How he could tell the differencebetween the rifles of friends and foe was a mystery to young Butler. Ere long the Rangers had narrowed down their circle until they wereable to see each other. For the past twenty minutes, they had beenstalking cautiously. Now they paused, after having exchanged signals. Deep growls were heard on all sides. 

"What does it mean?" questioned Tad. 

"It means those fellows have given us the slip again, " grunted thecaptain. "They've managed to slip through our lines somehow. Well, never mind, we'll get them one of these times. I thought we had thempocketed this time so there would be no escape. "

Tad had thought so, too. He was convinced that there was more to thisescape than even the Ranger captain realized. The boy did not wishto make suggestions so he kept silent. Yet he determined to make aninvestigation on his own hook on the following morning, provided theywere anywhere in that vicinity. 

There was nothing more that the Rangers could do. Their prey hadeluded them, disappearing as suddenly as if through a hole in theearth. It was the first time that such a thing had occurred toCaptain McKay and his failure bothered him, but he presented a smilingface when, after having withdrawn a mile or so, the men went intocamp for the rest of the night, building up a campfire and puttingout a heavy guard to prevent a surprise during the night. 

"Don't you think the rascals have a hiding place there where theyevaded us so neatly?" asked Tad, upon getting the captain's ear. 

"There is no hiding place there. I know the locality well, " wasthe terse reply. 

"But surely they could not have got through your lines, " objectedthe boy. 

"Yet they did. That's all there is to it. "

Not a man of the Rangers had been hit, nor was it believed that anyof the enemy had been wounded. Night shooting at skulking figures ina forest is uncertain work. Tad realized a sense of thankfulnessfor this. He was not anxious to see bloodshed, but now that thedanger was over, Chunky grew very brave. He told them all aboutit and how "We" had driven the bandits off. The story grew and grewwith the telling until Stacy was convinced that he had fought a verybrave battle. 

Tad lay awake a long time that night thinking over the occurrencesof the evening, pondering and seeking for a solution of what heconsidered was a great mystery. On the following morning the greaterpart of the band were off at an early hour, before the boys had risen, on a day's scout, to try to pick up the trail of the bandits. It wasto be a day of excitement for some of the party and hard work forothers, for many miles would be covered by the Rangers before theirgrilling ride came to an end. 

CHAPTER XX

LEARNING SOME FANCY SHOTS

After breakfast Captain McKay took an hour's ride alone over thesurrounding country. In the meantime the boys pitched a more permanentcamp as it was more than likely that they would remain there foranother night, since McKay did not seem to want to leave the placejust yet. What he had in mind the boys did not know. 

Returning from his ride the captain appeared to be in much betterspirits. His was a strange make-up. None wholly understood CaptainBilly. Perhaps that was one of the reasons for his success in hisperilous calling. 

"Well, I promised to give you boys some lessons in revolver shooting, "he said, tossing the reins to Tad who had come forward to take the pony. "Who can put a hole through my sombrero?" cried the Ranger sending hisbroad-brimmed Mexican hat spinning up into the air. 

A flash and a bang followed almost on the instant. The Pony Rider Boyshowled. The shot had been fired by Professor Zepplin and he haddrilled a hole right through the Ranger's sombrero. 

"Well, now, what do you think of that?" gasped Chunky, his eyesgrowing large. "I didn't think you could hit the side of a barnunless you were inside the barn. "

The professor smiled grimly. 

"I used to be counted the best revolver shot in my regiment when I wasin the army. But I'm a little slow these days. "

"Humph! I see you are, " grunted Billy. "Lucky for me that you aren'tquick or I wouldn't have had any hat left by this time. Anybody elsewant to try to put a hole through my hat?" he asked looking about. 

"I was going to suggest that we throw up the professor's hat andlet you take a shot at it, " suggested Tad, coming up at this juncture. 

"Here it goes, " cried the professor sending the hat spinning away fromthem, with the edge of the brim almost toward them. The hat wasspinning low and a very difficult mark to hit. 

Tad thought the Ranger was going to take a shot at it, but insteadof doing so, McKay nodded to Tad, with a merry twinkle in his eye. 

Tad whipped out his revolver with a quickness that amazed the Ranger, and let go. His bullet snipped a piece from the edge of the rim. Theforce of the bullet turned the hat crown toward the shooter. 

Bang, bang, bang! Tad bored three holes through the crown to thecaptain's amazement. 

"There! I guess we are even with you now, Professor, " laughed the boy. "That old hat of yours won't hold water next time you go to the spring. "

"I thought you folks didn't know how to shoot, " wondered the Ranger. "I guess I'd better take some lessons from you instead of you fromme. That certainly was mighty fine gun work. Where did you learn?"

"Since we have been out. I am not much of a shot with the revolver, though. I think I can do better with the rifle. "

"How about the rest of you?" questioned the captain. "Do all of youshoot like that?"

"I suppose I am about the best shot in the outfit, " answered Stacypompously. "I can hit a penny---"

"Yes, if the penny is glued to the muzzle, " interrupted Ned. 

"We'll see what you can do. "

Stacy, after three shots, failed to hit the hat once. Walter and Nedeach succeeded in placing a bullet through the professor's hat. Chunkyinsisted that his bullet went through one of the holes made by TadButler. He declared that he had never missed an easy shot like that inhis life. 

"Here, hit my hat, " commanded Tad, tossing his sombrero into the air. The fat boy watched the soaring hat with longing eyes. 

"Shoot, shoot, why don't you?" jeered the Pony Rider Boys. 

"All right if you say so. "

Stacy's pistol stuck in the holster and by the time he had freed theweapon the sombrero was only some seven or eight feet from the ground. 

"Yeow!" howled the fat boy letting go two bullets with a speed thatthey had no idea he possessed. 

"It's a hit!" cried the professor. 

Tad ran forward and picked up the hat. 

"Well, what do you think of that?" he wondered. 

"Did he hit it?" called Walter. 

"Of course he did. "

"Oh, pooh! That hole was in your sombrero before he shot, " scoffedNed Rector. 

"You are wrong. There were no holes in the hat. Now there are two. Stacy sent two bullets through my hat instead of one. "

"Hooray!" shouted the boys. 

"I didn't think it of you, Brown, " smiled the captain. "I take backall I have said against your character and your ability. "

"Oh, don't mention it. That's nothing. I usually shoot my hat fullof holes before breakfast every morning when I'm home. Anybody elsewant his hat transformed into a sieve?"

"I think you have done quite enough, " returned the professor. "Youhave done fully as well as I could have done. Ahem!"

"Really remarkable shooting for tenderfeet, " declared the captain. 

"Tenderfeet? Well, I like that!" grumbled Stacy. "Why, I'm a lionfighter, I am!"

"And a snake man as well, " grinned the Ranger. 

"Yes. I'm no tenderfoot. Did I run away when the shooting was goingon last night? I guess not. I-----"

"No, he was too scared to run, " snorted Rector. 

Stacy regarded Ned solemnly. 

"Ned Rector, I don't usually acknowledge you to be right in matterslike this, but I'm going to admit before the whole company that you'vetold the truth for once in your---"

"I always tell the truth, " broke in Ned. 

"---life, " finished the fat boy. "I was, as our distinguishedfellow---tenderfoot says, scared stiff. But if the truth were known, I'll wager that he was hiding behind a rock when that same shootingwas going on. "

Rector flushed a rosy red, which brought a howl from the boys. It wasplain that Chunky had touched him in a tender spot. 

"Come now, you boys, if you want to try some more, " called the Ranger. 

"What now?" asked Tad. 

"I want to see how you are on the draw---quick. " The captain trimmeda piece of paper down to about the size of a silver dollar. This hepinned to a tree, then measuring off twenty paces, faced the mark, spun about on his toes, making two complete whirls and drove a bulletright into the center of the target, having drawn his revolver as heturned. It was a splendid piece of shooting. 

The professor missed. He did not even hit the tree. Tad took apiece out of the edge of the target the first time. The second heplaced a bullet just inside the outer edge, which McKay pronouncedto be excellent shooting. That was high praise from a man likeBilly McKay. 

Ned did not know whether he wanted to try that shot or not. McKayexplained how to draw quickly and at what point of the whirl to draw, but try as he would Rector could not hit the mark. Once he chippeda piece of bark from the tree, which brought a yell from the boys. 

"The trouble with you lads is that you grip your guns too tightly. Take a light hold on the butt of your revolver. Toy with it. It'sthe fellow with the feather-weight touch that does the best work withthe revolver. He is the man to look out for. "

"That's the way I always shoot, " declared Chunky pompously. "Ifthere's one shot that I can make better than another it's that oneyou fellows have been trying. Why, I could pink that target withmy eyes shut. "

"Try it. See what you can do. Perhaps you may beat us all, whoknows?" grinned McKay. 

"I don't say that I can beat _you_, but I can shoot as well as theseamateurs who have been trying it. I can---"

"Look here, are you going to make that shot, Chunky?" demanded Rector. 

"Yes. Got any objections?" asked Chunky turning to Rector with greatdeliberation. 

"Not the least, if you'd kindly hold your fire till I can get behinda rock or a thick tree. "

"Yes, that's the place for you, I reckon. All ready, Mr. McKay?"

"It's up to you, " smiled the Ranger. "Does it make any particulardifference to you which way I whirl?" asked the fat boy. 

"Not in the least. You may stand on your head and whirl if it willsuit you better. "

"For goodness' sake, do something, " begged Tad. "You've taken enoughtime already to shoot the tree clean off the map. "

"Who's doing this shooting, you or I?" asked Chunky. 

Tad sat down helplessly. Stacy was not to be hurried. The more oneurged him, the slower did he become. 

"Look out, I'm going to shoot now. Everybody lie low!"

Stacy spun himself around like a top. He had whirled three timeswhen the Ranger shouted to him. 

"Shoot before you get so dizzy you can't see!"

Bang!

"Stop it---"

Bang!

"Stop it, you idiot!"

McKay struck the fat boy's revolver just in time to prevent getting abullet through his own body. Over yonder the professor lay flat onthe ground with a frightened look on his face, shouting at the top ofhis voice. 

"Hold him! Hold him! He'll have us all riddled!"

"Wha---what's the matter?" demanded Stacy looking around innocently. 

"Matter? See what you have done. "

"Di---did I wing the professor?" questioned the fat boy innocently. 

"Did you wing him!" jeered Tad Butler. 

"Come here, young man. But leave that pistol behind you, " commandedProfessor Zepplin. "I think we will equip you with a small bow anda blunt arrow after this. Even. Then I fear our eyes will be indanger. Do you see what you did?"

One of Stacy's bullets had bored a hole through the crown of theprofessor's sombrero. The other had plowed a neat furrow throughProfessor Zepplin's grizzled whiskers, close to the chin. 

"Ho, ho, ho! Haw, haw, haw!" roared the fat boy with head thrown backas far as it would go without dislocating his neck. 

CHAPTER XXI

A HOLE IN THE MOUNTAIN

The professor gave Stacy a shaking that the fat boy did not forget atonce, the others shouting their approval. The fat boy grinned afterhis punishment. 

"I'm a regular William Tell, eh?" he asked looking about. It wasstill a good joke to him. Even the professor permitted a grim smileto show itself at the base of his whiskers. 

"You came near killing Professor Zepplin, " answered the Ranger. 

"That would have been too bad, " replied Stacy almost anxiously. "Ishouldn't have had anybody to tease then. Do I try that shot again?"

"You do not!" was the firm reply from McKay. 

"I guess I knew what I was about when I hid behind that rock, " laughedRector. 

"According to Chunky, you knew what you were about when you got behindthe rock during the shooting yesterday, " cut in Tad. 

"Come, come, boys, if you are going to shoot any more you'd betterget busy. I shall soon have to leave you. Who shoots next?" demandedthe captain. 

"I do, " announced Stacy. 

"You shoot no more in this camp, young man, " insisted the professor. "It's all right for those who know how, but you endanger our liveswith your irresponsible actions. "

"All right, Butler, I will now throw my hat up from behind you. You will turn and shoot at it when I give the word, " said the captain. 

The first shot Tad missed the hat by some three or four rods. How theboys did shout and jeer at him!

"I did better than you. I trimmed the professor's whiskers, " declaredChunky. 

Tad nodded to McKay that he was ready for another shot. 

"Don't shoot this time until you see the hat. Shoot a little underrather than over it. The natural tendency is always to overshoot, whatever one is shooting at. "

Bang!

The hat in the air jumped as if it had received a sudden blow as Tadwhirled and let go. 

"You've graduated. Next!"

Rector missed five shots. Walter fanned the rim, then they called ahalt in the practice. 

"Altogether I am well satisfied with your shooting, boys. Even Brownaccomplished something, " said McKay. 

Stacy grinned broadly. 

"I---I could hit a German, couldn't I?" he stammered. 

"Yes, I think you could, " laughed Billy. 

"Especially if you were to turn your back to him before shooting, "added Tad. 

"Professor, " said McKay, "I must go away for part of the day. I donot believe your party will have any difficulty. The bandits are nolonger here. I should not be at all surprised if my men were toround them up, as they are on the track of the enemy at this verymoment. If you want to move, you may do so, but I would suggest thatyou make this your camp for the night"

"I am quite well satisfied here. The boys will no doubt want to goout exploring. I am somewhat interested in the geological formationof the canyon at this point, so we shall all be well occupied duringthe remainder of the day. You plan to return here to-night?"

"I think so. "

"We will see if we can't pick up the trail of the enemy, " laughed Tad. 

"Do so by all means. Who knows but that you may discover somethingworth while? I am sure you have an idea in your mind, " answeredMcKay, giving Butler a shrewd glance. 

"I will confess that I have, sir. "

The Ranger captain did not say where he was going. But shortly afterthat he rode out of camp and was seen no more until late that evening. After the departure of McKay the professor cleared his throat andstroked his damaged whiskers. 

"I trust you young men will try to keep out of trouble to-day. I amsorry to say that you are becoming rather too venturesome. Be goodenough to keep in mind that we are in what appears to be a hostilecountry. "

"It strikes me that Chunky is more hostile, more to be feared, thananything else about here, " chuckled Tad. 

"I agree with you, and for that reason I am going to place Stacy underyour charge for the day, Tad. "

"Oh, what a responsibility!" mocked Butler. 

"I'm glad it isn't up to me, " declared Ned. 

"You will look after Walter. "

"I don't need any looking after, " protested Perkins. 

"That's why he's put you in charge of Ned, " scoffed Stacy. 

"Shake hands. We will take a fresh start, Chunky, " said Ned, extendinga friendly hand. 

Chunky regarded Ned suspiciously. He wondered what Rector had in mindto induce him to become so friendly all at once. As it chanced Nedfelt that perhaps he had been rather too hard on the fat boy. But thefat boy had never thought of it in that light. Each was supposed totake the jokes played on him and without losing his temper. As a ruleeach one did, though Chunky seemed to get more than his share of suchabuse. Perhaps he brought his troubles on himself. 

"Well, if I am going to have charge of you, Stacy, I think I'll takeyou out in the woods where you can't do any damage to any one butmyself. Bring your gun and we'll go shooting. "

"My rifle?"

"No. Your pistol. "

"That suits me. I am too delicate to tote a rifle around on my shoulderall day. "

"Be back early, and do not go far away, " ordered the professor. 

"Shoot off a rifle if you want us before we get back, " suggested Tad. 

"Which way are you going?" asked Ned. 

"South. Which way do you go?"

"I guess we will go west if you are going south. I want to get a gooddistance away if you fellows are going to shoot at a mark. "

"Come on, Stacy. "

The fat boy and his companion strolled off. They were going to taketheir ponies, but the professor had decided against this, fearing thatthe boys would stray too far from camp were they to ride. Being onfoot he felt reasonably certain that they would not get far away, knowing how averse they were to walking, which is usually the casewith those used to riding a horse. A cowboy will mount his pony ifhe wants to go across the street, just the same as a fire chief willget into his buggy if he goes to a fire on the same block. 

Stacy and Tad engaged in a friendly conversation on the way out. Tadwas giving his companion some advice. They were talking seriously andfor a wonder Stacy was giving serious consideration to what Butlerwas saying. 

They had been going along aimlessly for nearly an hour, halting nowand then to sit down on a rock or a log, when Stacy paused, lookingabout him curiously. 

"Isn't this the place where we were shot at last night?"

"Yes, this is the place, I guess, " answered Tad, looking about himinquiringly. "Over yonder is where we were stationed. Let's go overand look about a little. "

Stacy was willing, so they strolled over. Tad sat down, a thoughtfullook on his face, taking a survey, forming a mental picture of thescene as it had appeared during the bloodless battle with the borderbandits. 

"According to my idea those fellows must have fallen into a hole inthe ground about where that tree is down, " declared Stacy wisely. 

"That is my idea too, " answered Tad. "I can't understand how they couldhave slipped by us as easily as they did. "

"Maybe they didn't. "

"They must have done so. There is no hole in the ground over there, asyou can see for yourself. Even if there were, what good would it havedone the men? Let's go over and see if we can pick up a trail of somesort. "

"I'm with you. Where shall we begin?"

"You go to the left and I'll go to the right. We will meet somewherenear the fallen tree unless we get side-tracked. "

The tree referred to was a huge one. It lay at the base of a greatpile of rocks, from which it evidently had slipped. In falling it hadcarried its roots with it. These roots, massed with dirt and stone, stood up in the air all of fifteen feet. The top of the tree was ahundred feet further out. It must have been a magnificent tree whenit stood towering from the top of the rocks there and no doubt was alandmark for all that part of the Guadalupe Range. The trunk at thetop stood free of the ground several feet, the trunk nearer the rootsresting on an almost knife-like edge of rock that had cut deeply intothe trunk when the tree fell. 

Stacy gazed at the tree and decided that it would make an excellentthing to climb. He stepped up on the trunk at the roots, walking outtoward the top. 

"Come on up. The walking's great, Tad, " he cried. 

"I'll be there pretty soon. "

After looking about for several minutes Butler followed his companion. But Tad paused before climbing up. He eyed that towering mass ofroots, dirt and stones with interest. 

"See anything funny?" called Stacy. 

"No, nothing particularly funny. I do see the print of a horseshoehere on the rocks where some dirt has stuck to the shoe and been lefton the stone. It isn't any of our stock as nearly as I can determine. I guess it must have been some of those fellows last night. Theyevidently were shooting from behind the tree here. "

"They weren't shooting from behind much of anything, as well as Icould judge, " answered the fat boy. 

Tad climbed up and made his way slowly along the tree trunk. As heneared his companion, he felt the tree settle a little. This at themoment did not make any particular impression on the Pony Rider Boy. Their combined weight might cause the outer end to give a little. Then all at once a howl from Chunky caused Tad to grasp a branch tosave himself. 

The tree top was settling slowly. 

"Look, look!" cried the fat boy. 

Tad turned, amazement growing on his face. The roots of the tree hadslowly risen several feet into the air, disclosing a hole in the rocks. 

Chunky was so excited that he fell off before Tad could say a word. Thetree settled back, closing the hole in the rocks. 

CHAPTER XXII

THE CAVE OF THE BANDITS

The top of the tree sprang up with such force, when relieved of theweight of the fat boy, that Tad Butler lost his hold and was catapultedto the ground, which he struck with a force that made his bones ache. 

The two Pony Rider Boys sat up rubbing themselves and looking intoeach others' faces. 

"Well, what do you think of that?" jeered Stacy Brown. 

"I think we got a fine tumble, " replied Tad, grinning. 

"And I think something else, too. "

"Yes, we've made a discovery!"

"A great discovery, " breathed Stacy tensely. 

"I think so, but that remains to be seen. Who would have thought it?But get away from here! We may have disturbed some one. "

The lads quickly scrambled up and, skulking into the bushes, croucheddown, watching the roots of the tree, almost expecting them to riseinto the air again. Nothing of the sort happened. The birds weresinging in the trees, the sun was shining brightly, the heat was intense. 

"I'm going to investigate, " declared Tad. 

"Maybe we've discovered another gold mine, or perhaps a German dugout, "suggested Chunky. 

"Perhaps, but not in the way you think. "

"How do you mean?"

"Wait until we investigate. There may be more to this than either ofus think. I wonder if we can weight that tree down so the roots willstay up in the air?"

"I saw some rocks there near the top. Perhaps we can make them stayon so the top will be held down. "

"You get up on the tree again and I'll pass the rocks up to you. Placethem so they won't slide off. I don't want to get crushed by themfalling on me. "

"Neither do I want to get thrown off again. I'm black and blue allover, right this minute. "

"I think I must be by the feel of my skin. Hurry!"

Stacy ran back to the roots, once more clambering to the trunk, alongwhich he ran clear to the outer end. Tad was ready with a heavy, flatrock which he carefully raised by main strength. 

"Now, don't you dare let that drop on me or I'll be mashed flat, Stacy Brown. "

"I---I won't let it d-d-rop un---unless I---I fall off. "

The rock nearly got away from the fat boy. Butler leaped back out ofthe way, but Stacy recovered himself in time and after some effortsucceeded in placing the rock in the limbs of the tree. 

"Fits as if it had been here before, " declared Chunky. 

"Perhaps it has. We shall see. Are you ready?"

"Yep. "

"Here's another. "

By the time the third stone had been put in place the top of the treebegan to settle. The fourth rock brought the tree down to the ground, exposing the opening in the rocks once more. 

"Hurrah!"

"Keep still. Don't move till I get enough up there to equalize yourweight. Then you may come down. "

The remaining stones were quickly laid in place. Tad motioned forChunky to descend. The fat boy leaped down. The tree top remainedon the ground leaving a wide opening in the rocks. 

"Now, Chunky, keep your nerve. You may need it. "

"What are you going to do?"

"I'm going in there. I think perhaps it might be the wiser plan foryou to remain out here and keep watch. "

"No, sir, I guess not! I've helped discover that hole and I'm going toreap my reward by exploring the inside. "

"Come along then. It is taking long chances, but I guess the tree issafe unless some one should come along and trip the stones. Then wewould be in a fine fix, shouldn't we?"

"I reckon we would. We wouldn't be getting out of that hole, rightsmart, should we, Tad?"

"I guess not. We should be buried alive. "

"Still, there may be some other opening to the place. We will take achance. Got your matches?"

"Yes. "

"Then you light a match when we get inside. I'll have my revolverready in case there is anything in there. "

Taking a final glance about, Tad moved toward the opening in the rockswith brisk step. Chunky was trotting along behind him, the fat boyfull of importance over the discovery they had made. At the openingthey paused, glancing apprehensively at the great roots toweringabove them. Were the butt of that giant tree to settle down now, itwould crush them. 

The boys stepped inside. They could see but a few feet ahead ofthem, but saw that they were in a huge crevice in the rocks, a sortof cave formed by the splitting apart of the rocks themselves, perhapsfrom some long past earthquake disturbance. 

"Light a match, Stacy. "

The fat boy did so. 

"There have been horses in here, " announced Tad. 

"Yes, I guess there have, but there aren't any here now. "

"Fortunately for us. "

The air was cool, though a little damp in the cave. To this the boysgave no heed. They had more important matters on hand than observingthe atmosphere of the place. The cave they found was much larger thanthey had had any idea of. In places the roof was all of ten feet high. But as they penetrated further in, moving cautiously, lighting the waywith every step, the walls sloped toward the back, approaching nearerto the floor. 

Except for the light from the matches, the boys were in darkness, sothat they were not able to observe that the opening to the cave hadclosed. A strong breeze, swaying the upper limbs of the tree, haddislodged the stones and allowed the roots to slip quietly into placeagain. The boys, without knowing it, were prisoners. 

"You aren't throwing your matches on the floor, are you?" demandedTad turning sharply. 

"Yes, why not?"

"Show me a light here, " commanded Tad going down on his knees andgathering up all the burnt matches he could find. "That is a finetrail you are leaving. Why, were any one to come in here, he woulddiscover instantly that strangers had been here. "

"I---I never thought of that, " stammered Chunky. 

"We must think of everything. Our very lives may depend on ourdoing so. "

"Wha---what do you mean, Tad?"

"Don't you understand yet?"

"I---I guess I begin to. Some---somebody's been here. "

"Yes. It is my opinion that the very men Captain McKay is looking forhave been here. Come, we must be quick! We are likely to beinterrupted at any time, though I hardly think any of them wouldcome here in the daytime. "

The boys were obliged to stoop in order to continue their explorationsfurther. After creeping under the low-hanging rock they found thatthey were able to stand erect once more. Then they discovered somethingelse. There were bales piled on top of one another, packs securelytied lying about, guns, rugs, in fact a miscellaneous assortment ofgoods which the boys believed to be of great value. In one cornerstood a chest securely padlocked. It was a rough chest, bound withiron bands that looked as if they might have been used on cotton bales. 

"Well, we have made a discovery, Stacy Brown!" breathed Tad. 

"We have, " agreed the fat boy, his eyes growing large with wonder. "What do you suppose is in that chest?"

"I don't know. "

"Let's open it, " suggested Stacy eagerly. 

Tad shook his head. 

"In the first place we have no business to do anything of the sort. In the second place I don't want to stay here much longer. We hadbetter be getting back to camp as quickly as we can. Of course wecan't do anything until Captain McKay returns, but the more quicklywe get away from here the better it will be for us. "

"I---I'm scared. Aren't you?" stammered the fat boy apprehensively. 

"No, I am not scared, but I realize that we are in danger everyminute we stay here. Those men wouldn't trifle with us, were theyto catch us. Do you know what they would do to us if they caughtus here, Chunky?"

"Nu---nu---no. "

"They would fill us full of lead, that's what they would do. Lightanother match while I look into this niche. Then we will be makingtracks for the outside. "

Tad was back by Stacy's side a moment later. He motioned that theywere to go back. The boys started briskly for the opening. Theinstant they had crawled out into the outer chamber they realizedthat all was not as it should be. At first they did not understandwhat had occurred. 

Tad was the first to make the discovery of what had occurred. 

"We're caught!" he cried. 

"H---ho---how?"

"The tree has closed the opening to the cave. Now we are in a nicepickle. "

Stacy was speechless. He held a burning match in his hand until thematch burned up to his finger, whereat Chunky dropped the match withan exclamation. 

"I---I'll tell you what let's do. Let's dig through the roots. We cando it. Come on. "

Tad laid a restraining hand on the fat boy's arm. 

"We won't do that just yet. This may have been an accident. Thosestones may have slipped off. I am inclined to think that is what hashappened. If so, we don't want to leave any clues---"

"I'd rather leave clues than to leave my dead body in here, " wailedChunky. 

"Buck up! Don't show a yellow streak, Chunky!" commanded Tad sharply. 

"I'm not yellow. But I know enough to know when I've got enough. Iknow I've got enough of this bandit-chasing business. I ought to haveknown better than to go out with you. They think I can't keep outof trouble. I can keep out of trouble all right if other folks don'tlead me into it. Now see what a fix you've got me into, Tad Butler!"

"It strikes me that I am in the same fix. But we're going to getout of it, Stacy---"

"Yes, but how?"

"I don't know, but I'll find a way. "

"Why, we'll starve to death in here. They'll find our bones here afew years from now and they'll wonder---I wish I had something to eat. "

"Tighten your belt. Remember, whatever occurs, you are to leave yourrevolver in its holster. Don't you dare to draw it unless I tell youto. One little slip might be the death of us. For once in your lifebe prudent. "

"I'll be prudent, but I wish I had a sandwich. Have you looked to seeif there's anything to eat in this hole?"

"No, I have something of more importance than food to think about atpresent. "

Tad struck a match, taking a long, careful look about the outer chamberof the cave. He saw nothing to encourage him. Rocks everywhere, withhere and there a discolored spot where tiny streams had trickledthrough, perhaps during a heavy rainstorm. 

Tad was thinking with all his might, trying to devise some plan bywhich they might protect themselves in case they were surprised bythe return of the bandits, which he did not think would occur beforenight, even if then. He reasoned that the bandits were far away elsethe Rangers would not have gone on a long journey in search of them. That meant that the bandits would not be likely to return until mattershad quieted down and the Rangers had left the locality. 

"I am afraid we are in here for a long stay, old chap, " Butler saidfinally. 

"Another case of being buried alive, eh?" questioned Stacy. "I toldyou so. I always am right. But I wasn't when I trusted myself to you. You can get into more trouble, and faster than---"

"At least I don't try to shave the professor with my revolver, " retortedTad sharply. "Hark! What was that?"

"I---I didn't hear anything. "

"Sh-h-h!" Tad gripped the arm of his companion. Stacy repressed an"ouch" with some difficulty. The two lads stood listening. 

Particles of dirt were rattling from the roots of the fallen tree, sounding like hailstones as they fell to the rocks in the cave. Thena faint ray of light appeared under the bottom of the mass of roots. 

"Somebody is coming, " whispered Tad. "Stand perfectly still until Itell you to move. "

"They can't see us at once. Don't make a sound on your life. "

"Wha---what are you going to do?" whispered Stacy, his teeth chatteringaudibly. 

"Duck, if I get half a chance. But I don't think I shall. There itgoes!"

The great mass of roots rose clear of the ground, exposing the fullheight of the opening, and the eyes of the two Pony Rider Boys grewlarge at what they beheld there in the framed circle of light, CHAPTER XXIII

IN A PERILOUS POSITION

As root mass swung upward, a man with a vicious slap on the animal'sthigh, sent a horse bounding in. He followed the horse. Then afterhim came five other men, crowding in with every appearance of haste. Not a word had been spoken up to this time. 

"Now run for your life!" whispered Tad in the ear of his companion. "No, this way. Stoop low. I don't want to get pinned in that otherplace. "

Tad had been using his eyes while glancing about the compartment, andusing them to good purpose. He had espied a heap of blankets, eitherdiscarded ones or some that had been used for the ponies. He wasinclined to the former opinion. He was quite sure that blankets wouldnot be used for the animals at this time of the year. At any ratethere was now no time for reflection. It was a time for quick action. 

Leading Chunky to the heap, which lay under a projecting ledge of rocksome four feet from the floor, Tad forced his companion over behindthe pile, then himself crawled in, puffing the blankets over them. 

Stacy's teeth were still chattering. 

"Stop it!" commanded Tad, giving the fat boy a violent pinch. 

This time Chunky did say "ouch!" But before the word was out of hismouth Tad had clapped a blanket over the offending mouth. 

"Do you want to be killed?"

"N---n---no. "

"Then keep still!"

"Wha---what are they doing?"

"That is what I want to find out if you will lie quiet and not give meany further trouble. They are staking their horses. This must be thestable. The men, as I thought, will go back further. I hope we canhear what they say. "

"I don't care what they say. I want to get out of here. "

"You never will if you don't muzzle yourself. Now do try to keepquiet while I listen. "

Tad raised his head cautiously, but quickly drew it back. What he hadseen was the face of the man who had passed himself off as captain ofthe Rangers when visiting the camp of the Pony Rider Boys a few daysbefore that. This was Willie Jones, the man for whom every Ranger inthe state was searching at that moment. And then---Tad shivered inspite of himself when he made the discovery---stepping up to the leaderto ask him a question was Dunk Tucker, the fellow whom Tad hadcaptured. Dunk had regained his freedom and had joined his band. Hispresence here indicated that it was not a good place for the PonyRider Boys. Tad hoped his own fellows might keep close to their camp. He wondered if the Rangers would be able to trace the bandits to theirlair, or if the former even knew the outlaws had returned to thatlocality again. The words of Tucker answered his question. 

"Well, we outrode them, Cap, " said Tucker. 

"Yes, but if you hadn't made a fool of yourself and tried a pot shoton McKay they wouldn't have known we were anywhere about. That wasa fool play on your part, Dunk. Your temper will be the death of you. We'll be lucky if it isn't the death of the whole outfit. I don't wantany more of it. If you can't control yourself better, the word willgo out that you aren't safe. You know what that means?"

Dunk grinned maliciously. 

"I reckon I do. How long we going to stay in here this time?"

"I'll let you know when I am ready to go. "

"But ain't you going to clean out that camp?"

"If you mean the boys, I am not. I am looking for bigger game justnow. When we get through you can settle your little grudge if youwant to. I reckon you'll get your fingers burnt, the same way youdid before, if you try it. Those boys are pretty slick. "

Tucker's face grew black. No need to tell Tad of what the outlaw wasthinking at that moment. He was thinking of the time when the boyshad made him a prisoner and how they had been responsible for hishaving been taken to El Paso and locked up. There was murder in theheart of Dunk Tucker at that moment, as Tad Butler well knew. 

The men had lighted candles and stuck them in crevices in the rocks, so that the chamber was fairly well lighted. The horses were whitewith foam, showing that they had been ridden hard. The watching boyunderstood. The bandits had been hard pressed by the Rangers. 

Jones walked away, leaving Tucker standing there nursing his deadlyrage. After a time Dunk followed into the other chamber, where themen fell to discussing their escape in tones plainly audible to theboys hidden under the blankets. From the conversation Tad drew thatthe men had been on a raid and that they had been forced to throw awaymuch of their plunder because of having been so hard pressed by thepursuing Rangers. Still, three small packs had been unloaded fromthe ponies in the cave and carried to the inner chamber. The outlawswere not in good humor. Their leader was the only one whose facereflected a smile. Willie could smile even when facing a gun. That smile had upset more than one man's aim and saved Willie's life. Jones fully realized the value of his disconcerting smile. 

Tad's reflections were interrupted by the voice of one of the outlaws. 

"They're here, " said the voice. "I'd like to take a pot at them. "

"It'll be your last if you try it, " threatened Jones. "This is theonly safe retreat we've got. We don't propose to give it away by any, such fool play as shooting at a Ranger from it, much as we'd like toget rid of some of those fellows. They're crowding us pretty close. And right here, I've got a proposition to make. By the way, Gregg, what are they doing?"

"Looking for trails. "

The outlaw captain smiled grimly. 

"Let 'em look. Precious little trail they'll find, and precious littlegood it'll do them if they do find it. "

"Joe said those stones weren't where he'd left them. "

"That's all right. Probably some of those boys have been foolingaround here. They're a nosey crowd. But there's no chance that theyhave discovered anything yet. Give them time and they may. Once webreak up the Ranger camp the boys will take French leave mighty quick. It will be too warm for them here. As I was about to say, I have aproposition to make to you. Until things quiet down a little it ismy suggestion that we get across the Rio Grande and go into retreatthere in our old joint. We've got a lot of valuable stuff here thatwe can't get out at present and we'll have to leave it here. TheRangers are watching this locality altogether too closely for comfortso far as we are concerned. Withem is nosing around El Paso as youknow, lying low for some folks that we know of there. No use totake chances when we don't have to. If you're all agreed we'll justslope to the other side of the river and lie low for a month. What'syour idea?"

"I'm agreed, if you'll give me a chance to get even with that gang ofboys first, " spoke up Tucker. 

"You mean that you want to stay here after we've gone?" smiled CaptainWillie. 

"I reckoned I'd like to until I'd done what I told you. "

"Well, I reckon you won't do anything of the sort. When we go out ofhere, none of us comes back till the whole crowd returns. Is thatclear, Dunk?"

The outlaw growled an unintelligible reply. 

"The Rangers have drawn off, Captain, " called the lookout. 

"Which way?"

"Toward the camp. "

"They're going to stay there all night, " decided the leader. "Well, we'll watch our chance and perhaps we'll be able to get away some timelate in the night. Are you all agreed on getting across the river ifwe can make it?"

The men said they were. 

"Then that's settled. Get out the grub. We'll feed up while we've gotthe chance. "

No fire was built. The men munched their food cold. Little was saidamong them. 

And now Tad began to ponder over certain other phases of his situation. How were these outlaws going to get out? There surely must be someway of opening the way to the outside. Still, the boy did not seehow they could move the tree from the inside. If they could do ithe could. He decided, however, that it would not be safe to trustto his finding the secret of the opening. Far better would it be tobolt at the first opportunity. 

Stacy had kept unusually quiet, though his eyes had grown large whenhe heard the conversation of the men. At least there was a peep-holethrough which the lookout was keeping watch. It occurred to Chunkythat he could yell after the men left, and thus attract theattention of his own fellows. Tad had a different idea in mind, though he had not yet fully formulated his plans along this line. 

The outlaws having finished their lunch, some rolled up in theirblankets and went to sleep undisturbed by the fact that a band ofRangers was encamped within a short quarter of a mile of them. 

As for the boys who were in such a tight place, they hardly dared movefor fear of frightening the horses and thus exciting the suspicionsof the outlaws further down the underground passage. When the boysdid change their positions it was done as cautiously as they knew how. One Pony near them evidently scented them, for it grew restless andkept snorting, but that was all. 

The hours dragged on wearily. The boys did not know whether it werenight or day. Finally the lookout came down to where Jones waspacing steadily back and forth. 

"Well?"

"Something going on over there, " answered the lookout, jerking his headtoward the opening. 

"What do you think?"

"I don't know. They're running around out there with torches. "

"Where are they?"

"On the other side of the clearing. "

"Got their rifles with them?"

"No. "

"McKay there?"

"The whole crowd's there. "

"They've missed us, " whispered Chunky. "They're looking for us. "

"Sh---h---h---h, " warned Tad softly. Jones pondered for a moment, thenhe turned to the lookout sharply. 

"Wake up the men, " he said. 

"I reckon something is going to be did, " whispered the irrepressibleChunky. Something was. 

CHAPTER XXIV

CONCLUSION

The waking of the men was a matter of seconds merely. A touch on theshoulder and the man touched was on his feet as if propelled bysprings, hand instinctively going to the revolver dangling from hisbelt. 

Tad, now keenly alive to what was going on, had partially thrown theblankets off, Chunky having done the same. 

"Don't stir. I'll tell you when it is time to move, " warned Tad. 

"Men, I've changed my mind, " announced the leader. "Are you ready fora fight?"

"Sure we are if it's Rangers you want us to fight, " answered a voice. 

"Yes, it's the same old crowd, and a bunch of youngsters thrown in. Idon't know what the trouble is, but they're racing around out therewith torches---"

"Mebby they've found the trail, " suggested one. 

"No, I reckon some of the youngsters have strayed away and got lost. All the better for us. The Rangers won't be looking for us. "

"They have left their rifles in the camp. They've got their revolverswith them, of course. Take your rifles. Put out all the lights, thenwhile the watch is being kept we'll step out and give them a volley. Be careful to get to one side of the opening so we don't draw theirattention too sharply to the opening. That might leave some marks andlead them to investigate when day comes. We'll be a long way fromhere by that time, but I hope we'll leave a few dead Rangers behind us. "

Dunk Tucker was grinning broadly. This was the opportunity for whichhe had longed. 

"Sneak out quietly. Take a good aim. Give them a rattler of a volley. Every man pick his mark. You can't miss. I'll look for McKay. Butdon't all aim at the same mark or you won't do much damage. "

Tad could not repress a shudder. He realized the desperateness ofWillie Jones' character fully now. A man who could plan such acold-blooded crime could have no heart. And the worst of it was thatTad saw no way to prevent the crime. 

"How about it up there?"

"They're over in the bush now. "

"I want them when they are just outside the bush. If their backs areturned toward us, all the better. We'll give them a hot dose that willgive them something to think about, " jeered Willie. 

"Well, isn't he the cold-blooded fish?" whispered Chunky. "I'd like totake a pot shot at him right where he stands. "

"So should I, " answered Tad. "But I couldn't do it, bad as he is. "

"No, I guess it wouldn't be exactly prudent, " returned the fat boy. 

"That wasn't what I meant. Prudence hasn't anything to do with it. It would be cold-blooded. "

"Ready! Work the lever, " commanded the captain as the voice of thelookout called down the one word "Right!"

"Get ready, " whispered Tad. "I'm going to bolt. Don't make a sound. We may lose our lives, but I'm going to save the others. If I shoot, drop in your tracks, but be careful not to drop in the opening. Nowthink as you never thought before!"

"Wha---what are you going to do?" stammered the fat boy. 

"Watch me. I can't explain it to you now. There goes the tree. "

The operation of the huge bulk was very simple. One of the menprocured a long pole from a crevice in the rock. This he thrust downunder the roots of the tree, adjusted it and then began working thepole as one would a pump handle. The tree began to rise at once. Tad saw that the outlaw was working a pneumatic jack, on which hefigured a piece of timber had been placed so as not to crumble thedirt from the roots when the bulk was raised by the jack. From theoutside the bandits no doubt used the same method that the Pony RiderBoys had used to gain an entrance. 

"Keep clear of the opening and don't shoot until we're all ready. One volley will be enough, then back and trip the jack. All ready!"

The men began creeping out, Willie Jones in the lead. 

"Now!" whispered Tad. "Follow me! Look out for squalls! Thingswill happen rapidly when they begin. "

The boys crept out, following the outlaws as closely as they dared. Once outside the bandits quickly skulked off to one side or the other. 

"Get down quick!" whispered Tad. 

"Bang, bang, bang!"

Tad Butler fired three shots from his revolver, then threw himselfon the ground. Almost with the first shot he heard the voice of theRanger captain. McKay, ever on the alert, was not caught napping. 

"Throw torches away! Down!" he roared. 

A thundering volley crashed from the rifles of the outlaws, answeredby a rattling fire from the revolvers of the Rangers. Tad heard anoutlaw utter an exclamation of pain and knew that one at least ofthe bad men had been raked by a bullet. 

"Back!" came the command from the leader of the bandits. The wordwas not spoken loud enough to be heard far away, but every man thereheard it, and back they rushed into the cave. A shower of dirt fellover the two Pony Rider Boys, who were by this time crawling on allfours to get away from the tree that they knew would come down witha bump. 

It did. The Rangers were still shooting. Tad and Stacy were in adangerous position. The Rangers were firing right over them. Theinstant the boys heard the base of the tree fall into place, Taduttered the owl call. 

"Don't shoot, don't shoot!" howled Chunky. 

"It's the boys! Stand fast. Lie low!" commanded the Ranger captain. "Something is going on here that we don't know about. "

A moment later Tad and Chunky came staggering into the arms of theirfriends. 

"Surround the base of the tree. They're in the cave, " cried Tad. 

"Wait, wait!" commanded the Ranger. 

In the cave the outlaws were beginning to think. Tad's shots had beenlaid to the carelessness of one of the men. Each one denied that hehad fired them. 

"That was a signal. Somebody here is a traitor!" cried the leader. 

Out there in front of the cave Tad was rapidly whispering to theRanger captain what had occurred. He told him the bandits were allin the cave and that he believed the only exit was there behind theroots of the big tree. 

"Boys, we've got 'em!" cried Billy. "We've got 'em in a trap. Hurrah! Tad, you've saved the lives of some of us. That was as bravea thing as ever a Ranger did and I'll tell you what I think about itafter we have smoked those ruffians out. "

The smoking-out process was a matter of some time. At the captain'sdirection, a row of fires was built in front of the cave so that noneof the outlaws could escape. On each side of the row of bonfiresMcKay placed flanking parties who stood with rifles ready to trainon the opening should the bandits seek to escape. 

All that night and the following day did the Rangers keep silentwatch over the cave. The second night fires were built up as before, and part of the force stood watch while the others slept on theground with rifles for pillows. 

It was not until about noon of the third day that any sign of lifewas observed in the cave. Willie Jones hailed the captain, declaringthat he was ready to surrender. Terms were quickly made. The menwere to walk out singly, leaving their arms in the cave. There wasno need to caution Willie Jones as to what would follow the leastsign of treachery. He knew without being told. Grim Rangers werestanding on one side so that they should have a clear shooting spacein front of them. Billy McKay stood directly facing the opening, asif for the purpose of tempting one of those desperate men in thereto take a shot at him. None had the pluck to try it. 

Jones was the first one out. He was manacled and searched. One byone the bandits emerged until every man was a prisoner. 

That afternoon all were on their way to El Paso. It would be manyyears before they would again terrorize the Rio Grande border if atall, for there were many charges against them. Among the chargespreferred against the bandits was that of aiding the Germans bystirring up trouble on the border. Not a man confessed, but whilethe government was unable to prove this particular charge, it waspositive that in the arrest of this desperate gang a nest of dangeroustraitors had been broken up. 

The entire credit for the capture was given to the two Pony Rider Boys, Tad Butler and Stacy Brown. The Pony Rider Boys party accompanied theRangers to El Paso, whence, later on, they continued their journey downthe Rio Grande. The boys were praised by every one for their bravery, and especially were Tad and Stacy, who had so bravely risked their ownlives to save the lives of their young companions and the Rangers. 

A big reward was earned by the Rangers, but at Captain McKay'ssuggestion, a thousand dollars was turned over to Professor Zepplin tobe divided between Tad and Chunky later on. The professor's protestsavailed him nothing. McKay said the professor might throw the moneyin the gutter if he didn't want it, so the professor sent the thousanddollars to the father of Walter Perkins. That gentleman deposited itto the credit of the two plucky young lads, though it was some time erethey knew the existence of this special fund, all their own. 

It was the last night in camp before ending their wonderful outing, andevery one was solemn-eyed and thoughtful. Their playspell was at anend and they were sad. Tad and Ned were speaking of the war, eachconfiding his desire to the other, to get into the fight, andexpressing his intention of doing so soon. 

"Professor, " called Tad. "We know of course how you feel on thesubject, but this is a good time for us all to make our confessions, on this the last night of our season's outing, and know where we standon the war. "

"We are all patriots here, " interjected Walter Perkins. 

"All but one and he's a German, " spoke up Stacy Brown. "I refer tothat noble man, Professor Zepplin, first cousin to the airship knownas a Zeppelin---"

Professor Zepplin's whiskers fairly bristled. 

"Young man, that will do!" he thundered. "I am an American citizen, and you have no right to question my loy-----"

"There, there, Professor, don't you know Chunky by this time? All hewished was to draw your fire and stir you up, which I reckon he'sdone, " soothed Tad laughingly. 

Stacy chuckled under his breath, at the same time keeping a weathereye out for any hostile move that Professor Zepplin might make, forthe professor plainly was excited. 

"That is all very well, young men, " returned the professor. "I knowthat you know what my Americanism is. I have no need to tell youthat, but, as Tad says, this is a good time for us all to declare ourloyalty, and we should reiterate it every day of our lives. "

"That's the talk, " cried Ned Rector. 

"As you boys know, I was born in Germany. I attended a German militaryschool and, to cut the story short, I became a German officer. I foughtin many battles---"

"At the battle of the Nile he was fitting all the while, " murmured thefat boy under his breath. Tad rebuked Stacy with a look. 

"One day, after I had served my time, I emigrated to America. It wasnot until then that I realized that I had been wrong, that I had beenupholding an unworthy cause. That was years ago. Soon I had absorbedthe spirit of American liberty and became at one with its ideals. I became a citizen. Of course I looked back on my army experience witha certain amount of pride. No one who has fought and bled can helpdoing that---up to a certain point. "

"I can well understand that, " murmured Tad. "I think I know how youfelt. "

"When Germany made war on little Belgium and France my pride ofservice turned to regret. I was sorry deep down in my heart thatI had served the Fatherland, but I rejoiced that I was then an American, a loyal American. It was when---when the despicable Huns sank theLusitania, the most dastardly crime in the world's history, that mysoul was suddenly filled with loathing. I offered my services to thecountry of my adoption, believing that they would go to war at once, but I was too old, and then America was not yet prepared for thegreat conflict. Since we went to war I have again offered myservices. I can still fight, young men. "

"I should say you can, " interjected Tad. 

"My name, at this time, is an unfortunate one, " continued the professor. "It is not the name, but the heart that counts, and my heart is in andfor America, and my life and all that I have or ever shall have ishers for the asking. "

The Pony Rider Boys with one accord sprang to their feet and, tossingtheir hats in the air, uttered a wild cowboy yell. Professor Zepplinheld up a hand. 

"Wait!" he commanded. "There is something yet to be done and now isthe time to do it. " Thrusting a hand into a pocket he drew forth aleather case and opened it with unsteady fingers. From the case hedrew a small object wrapped in tissue paper. 

"The Iron Cross, " murmured the boys. 

"Yes, it is the Iron Cross, " agreed the professor. "Time was when thiswas my most priceless possession. Now I loathe it. Its possession hastroubled me greatly of late and it has been my intention to rid myselfof the hateful thing. Boys, what shall be done with it?"

"That is for you to say, Professor, " answered Tad in a low voice. 

"Get an axe, " advised Chunky. 

"Yes, yes, the axe, " agreed the professor. 

Tad handed the tool to the professor. The latter placed the onceprized decoration on a stone and with one blow from the axe smashedthe cross. Blow after blow he rained on the medal until it layscattered in pieces. These the professor gathered up and hurled farfrom him. 

"That is what I think of Germany, monarchial Germany, the assassin ofinnocent women and children. "

"Boys, 'The Star-spangled Banner, '" cried Tad after a moment ofimpressive silence. 

The youthful voices of the Pony Rider Boys rose in the National anthem, the deep bass voice of Professor Zepplin booming out above all the rest. 

When next we meet our boys we shall find them in utterly differentsurroundings. In the next volume of the present series our readerswill find an extremely fascinating tale. It is published under thetitle, _The Pony Rider Boys On The Blue Ridge; Or, A Lucky Find inthe Carolina Mountains_. 

THE END
