cal 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 spirochaetic 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
much of the world is deceitful and degrading in sex matters, and that if
she would be a perfect woman, mentally and physically, she must vigilantly
guard her virtue, maintaining absolute purity, not only with persons of
the opposite sex, but with persons of her own sex, and the person of her
own self. Incalculable good can be done toward the uplift of wayward
humanity by sex education.

CHAPTER V

ECONOMIC PHASES

_By Arthur Evans Wood_

In any effort for social improvement it is necessary to know conditions
that make both for and against success. This is especially so in social
hygiene, for it is closely related to all aspects of modern life. Lack of
education and false instruction are largely responsible for sexual
immorality. It is not so generally known that economic conditions are
responsible for vice, opinions on this matter ranging all the way from a
denial that economic conditions have anything to do with vice to the
assertion that vice woul
