pertaining to sex development, ignorance of which is often baneful to the
developing adolescent of either sex. When the boy's voice begins to
change, and hair begins to appear on his face and body, and more thrilling
sensations occasionally command his attention, he should be told, modestly
but distinctly, that a pure and manly function is developing within him,
the sole object of which is reproduction, and he must not consider it in a
vulgar way, nor discuss it with others than his parents or physician or
minister. Tell him that these physical changes of oncoming manhood are due
to the establishment of the secretion of the procreative fluid,--the
semen,--and will be safely cared for by nature. Fortify him against the
mental pollution of the quack advertisement, and the satanically false
teaching of ignorant associates that sexual intercourse is physiologically
necessary, by impressing him with the fact that nature cares for the
disposal of the seminal secretion. When clearly made aware of these simple
sex principles, and convinced that it is unmanly and depraved to consider
them vulgarly, the rapidly developing manly boy will not become a
masturbator or a frequenter of bawdy-houses and a victim of the gonococcic
or spirochætic infections; nor will he become a moral assassin, a seducer
of girls.

The sister, no less than the brother, needs pure, plain, non-prudish sex
education. If her mother is not qualified to impart it, she, like the boy,
should seek the aid of her minister, or physician, or a qualified school
teacher; better a few suggestions from an experienced, modest source than
many suggestions from inexperienced and often lewd companions. As the
brother was told of the physical phenomena accompanying his sex
development, so the sister should be apprised of the physiological
necessity of her periodical functions, and of nature's kindly care and
development of her delicate and wonderful sex mechanism, the sole purpose
of which is maternity. It will fortify her maidenliness to tell her that
