d experts will tell us with more confidence how
to do our duty to the manifold exigencies, types and stages of
youth, and instead of feeling baffled and defeated, we shall see
that this age and theme is the supreme opening for the highest
pedagogy to do its best and most transforming work, as well as
being the greatest of all opportunities for the teacher of
religion" (Stanley Hall, _Adolescence_, vol. i, p. 469). "At
Williams College, Harvard, Johns Hopkins and Clark," the same
distinguished teacher observes (ib., p. 465), "I have made it a
duty in my departmental teaching to speak very briefly, but
plainly to young men under my instruction, personally if I deemed
it wise, and often, though here only in general terms, before
student bodies, and I believe I have nowhere done more good, but
it is a painful duty. It requires tact and some degree of hard
and strenuous common sense rather than technical knowledge."

It is scarcely necessary to say that the ordinary teacher of
either sex is quite incompetent to speak of sexual hygiene. It is
a task to which all, or some, teachers must be trained. A
beginning in this direction has been made in Germany by the
delivery to teachers of courses of lectures on sexual hygiene in
education. In Prussia the first attempt was made in Breslau when
the central school authorities requested Dr. Martin Chotzen to
deliver such a course to one hundred and fifty teachers who took
the greatest interest in the lectures, which covered the anatomy
of the sexual organs, the development of the sexual instinct, its
chief perversions, venereal diseases, and the importance of the
cultivation of self-control. In _Geschlecht und Gesellschaft_
(Bd. i, Heft 7) Dr. Fritz Reuther gives the substance of lectures
which he has delivered to a class of young teachers; they cover
much the same ground as Chotzen's.

There is no evidence that in England the Minister of Education
has yet taken any steps to insure the delivery of lectures on
sexual hygiene to the pupils who are about to leave school. In
Prussia, however, the Ministry of Education has taken an active
interest in this matter, and such lectures are beginning to be
commonly delivered, though attendance at them is not usually
obligatory. Some years ago (in 1900), when it was proposed to
deliver a series of lec
