The parents who wish to prepare themselves with a knowledge of what to tell their children in place of the old stork fable; of when to tell, instead of postponing to a dishonest "some other time"; and of _how_ to tell, instead of in the embarrassing, half-expressed vagueness, would do well to read some of the abundant literature on this subject that has been issued in recent years just for our help: Some of the best titles are given below. The following titles, with comments, are taken for the most part from "A Selected List of Books for Parents," issued by the Federation for Child Study: BIOLOGY OF SEX. By T. W. Galloway. A concise and reliable statement of fundamental sex facts. GIRL AND WOMAN. By Caroline Latimer. Very helpful in understanding and dealing with the physical, mental and moral disturbances of girlhood and early womanhood.

Emphasis is laid upon the religious and spiritual sides of the emotional life, upon training for self-control and the mastery of moods and instincts. SEX. By Patrick Geddes and J. Arthur Thompson.

Covers the problems of sex education and of criticisms of sex education. SEX EDUCATION. By Ira S. Wile, M.D. An excellent little volume for the purpose of assisting parents to banish the difficulties and to suggest a plan for developing a course in sex education.

A brief presentation, from a lofty point of view of the many phases of the sex problem as it confronts the boy. The following books on sex education were written for children.
