This is a brief and readable statement of the experiences of the Commonwealth Fund for the Prevention of Delinquency. It is written in nontechnical language, like most of the material on child guidance at the present time. The book is well illustrated with case records presented in such a form as to be really useful, and it deals with questions that occur in every family. To parents and teachers, to pediatricians, in fact, to any one who is daily faced with behavior and social problems of children, this book will be most helpful. The general get-up of the book, like that of all books published by the Commonwealth Fund, is excellent.
