eugenic propaganda has found its field of promise and is unassailable
reason for active existence.

Let us take another illustration, so that mother may have a full
understanding of the far-reaching effect of the "tendency to disease."

We cannot justly assume a child to have outlived its hereditary
tendencies until it has reached the period of its full growth,
physically, mentally, and morally. We know that this period is about
the twenty-third year. Now a young girl of eighteen, or even twenty, who
is successfully resisting an inherited tendency, is likely to reach her
full physical and mental growth, providing she does not subject her
vitality to a serious physical strain, or providing she is not the
victim of a serious illness. Suppose this young girl marries and becomes
pregnant; this condition immediately changes the fighting or resisting
equation; she is no longer conserving her strength and energy; she is
spending it out, wasting it so far as it applies to her own upbuilding.
The percentage in favor of a successful fight against the inherited
tendencies is greatly reduced, and as a matter of fact, statistics
show--as is fully explained in the article on "The Evils of Early
Marriage"--that many of these young mothers succumb to disease as a
result of pregnancies at this period of immaturity, when they could have
otherwise lived. The "tendency to disease" has therefore an economic
value and the state should build along the line of the conservation of
health in its broadest sense.

THE BEST TREATMENT FOR TUBERCULOSIS.--The most important factor in the
present-day treatment of consumption is the right kind of nourishment.
This cannot be emphasized too strongly. In the first edition of this
work, it was stated that the most important factor in the treatment of
this disease was fresh air. The author has had very good reasons to
change his opinion radically in this respect.

So emphatically may this truth be asserted that it is now not at all
necessary to seek a change of climate in the hope that such a change may
aid the patient. It must not, however, be understood that this reasoning
applies to charitable cases. If the patient is so situated that it is
not possible to provide a proper environment, a change may do good. It
is not the change of air that is responsible for the improvement,
however, though it no doubt contributes in these cases; it is the
altered environment.

Patients who in their own homes enjoy
