First published in 1913. Part of the Self and Sex Series. According to the Preface: "During a number of years it has been my privilege to be the confidante and counsellor of a large number of young women of various stations in life and in all parts of the United States. These girls have talked freely with me concerning their plans, aspirations, fears and personal problems. It has been a great revelation to me to note with what unanimity they ask certain questions concerning conduct--queries which perhaps might astonish the mothers of those same girls, as they, doubtless, take it for granted that their daughters intuitively understand these fundamental laws of propriety. The truth is that many girls who have been taught in the "ologies" of the schools, who have been trained in the conventionalities of society, have been left to pick up as they may their ideas upon personal conduct, and, coming face to face with puzzling problems, are at a loss, and perhaps are led into wrong ways of thinking and questionable ways of doing because no one has foreseen their dilemma and warned them how to meet it."
