Dr. Crampton has written a book that almost every boy between the ages of 8 and 15 can read with pleasure and profit. It is a simple and practical program of health management which seeks to coordinate all the social agencies that touch on the youth's daily life. The style of the book is direct and engaging and cannot help but elicit the reader's interest. The author's long experience with youth activities is admirably reflected in the organization of his text. The information is sound, stimulating and written in the boy's language. Each chapter is concise, explicit and well illustrated by diagrams. The book should be part of the library of every growing boy.
