cates lack of eugenic
value; but it is worth noting that the number of offenders who are
feeble-minded is probably not less than one-fourth or one-third. If the
number of inebriates could be added, it would greatly increase the
total; and inebriacy or chronic alcoholism is generally recognized now
as indicating in a majority of cases either feeble-mindedness or some
other defect of the nervous system. The number of criminals who are in
some way neurotically tainted is placed by some psychologists at 50% or
more of the total prison population.

Add to these a number of epileptics, tramps, prostitutes, beggars, and
others whom the census enumerator finds it difficult to catch, and the
total number of possible undesirable parents becomes very large. It is
in fact much larger than appears in these figures, because of the fact
that many people carry defects that are latent and only appear in the
offspring of a marriage representing two tainted strains. Thus the
feeble-minded child usually if not always has feeble-mindedness in both
his father's and mother's ancestry, and for every one of the patent
feeble-minded above enumerated, there may be several dozen latent ones,
who are themselves probably normal in every way and yet carry the
dangerously tainted germ-plasm.

The estimate has frequently been made that the United States would be
much better off eugenically if it were deprived of the future racial
contributions of at least 10% of its citizens. While literally true this
estimate is too high for the group which could be considered for
attempts to directly control in a practical eugenics program.

Natural selection, in the early days of man's history, would have killed
off many of these people early in life. They would have been unable to
compete with their physically and mentally more vigorous fellows and
would have died miserably by starvation or violence. Natural selection's
use of the death-rate was a brutal one, but at least it prevented such
traits as these people show from increasing in each generation.
Eugenists hope to arrive at the same result, not by the death-rate but
by the birth-rate. If germinally anti-social persons are kept humanely
segregated during their lifetime, instead of being turned out after a
few years of institutional life and allowed to marry, they will leave no
descendants, and the number of congenital defectives in the community
will be notably diminished. If the same policy is followed thro
