Preface: The object of this little book is to make children think about health, for while it may be never late to mend bad health habits, it is never too early to form good ones. Health cannot be forced from without; it must be fostered from within. It is not enough for us to provide our children with proper food, clothe them suitably and keep them clean. We must also give them an intelligent understanding of the hows and whys underlying the laws of hygiene, and must impart to them the contagion of our own enthusiasm for health...... This unusual book will appeal greatly to all who have an interest in teaching children. Many of the earliest books, particularly those dating back to the 1900's and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
