must, and will answer truly and purely, all questions in these matters on
which the child and youth are now left to random, miscellaneous,
clandestine sources, and get vile, false, and pernicious answers.

As childhood passes into youth and the pubertal changes begin, the
objective curiosity of the earliest years passes gradually into the
intense concern of personal problems. The general principle is the same:
do not drag in the subject of sex and reproduction, but do not evade or

knows will receive his advances with sympathy, answer his questions with
frankness and intelligence, and hold his confidence sacred. Happy the
youth or maiden who has such a guide in the crises of unfolding powers and
