48 pp. An educational guide about sexual activity, designed to prepare young men and women to approach it responsibly. From the preface: "This booklet is meant for the young people between the ages of thirteen and eighteen the normal high-school age. It is not a guide to marriage. It is a guide to conduct during the years of adolescence, when the way that young people live and the characters that they develop will profoundly affect their happiness later in marriage - or mean its failure and collapse."
