Problems of Child Welfare. By George B. Mangold. (Macmillan and
Co. 8s. 6d. net.)—Dr. Mangold, who is the Director of the School of Social Economy in Washington University, has contributed a learned and thoughtful volume on a very important subject to the series of "Social Science Text-Books" edited by Professor R. T. Ely. His aim is "to present in a systematic way the principles of child welfare, and to correlate the different problems involved." The sections into which the book is divided deal respectively with the conservation of life, health and physique, training and education, child labour, juvenile delinquency, and the problems of dependent children. The instances are mainly drawn from the United States, and the book should be very valuable to English students of this great and difficult problem, on the successful solution of which the increase of the world's efficiency and happiness so largely depends.
