t, but much is being done now in this country. In
America the subject is largely under the auspices of the American
Breeders Association, which has organized an extremely efficient
Committee on Eugenics with which a large number of biological and
medical workers are cooeperating. This committee has cooeperated in the
establishment of a Eugenics Record Office, at Cold Spring Harbor,
under the direction of H. H. Laughlin. Relevant facts are beginning to
pour in from many directions; eugenic ideals are being given practical
expression, and the science is rapidly gaining headway.

It may be asked: "Well, what is it all about; are we as a nation not
doing well--well enough?" Is it not true, as some have suggested, that
this eugenic movement is but one more expression of England's
temporary national hysteria transferred to this country? In answer to
such queries let us state some of the conditions which have suggested
to so many sober thinkers and observers that the time is arriving, has
in fact arrived, when we must begin to think of the future of our
communities and nations and of our race, rather than contentedly to
read of and meditate upon the great achievements of our past, or to
parade with self-satisfied air through our glass houses of Anglo-Saxon
supremacy. Even were we unthreatened, were we amply holding our own,
the mere fact of the possibility of a natural increase of human
capacity would make it a practical subject of the utmost importance.
We may be sure that somewhere a nation will avail itself of such a
possibility as the increase of inherent native talent, physical,
mental, moral, and will tend to become a strong and dominant people.
Why should not _we_ be that people?

It seems that the facts that lead us to think of the future in this
matter are of two quite distinct classes. First, we have a great mass
of data relative to the composition of our societies and to the
changing character of our population, social data of deep significance
when broadly viewed and thoughtfully considered. Second, there are
certain biological considerations, which all apart from existing
social conditions should warn us to be on the lookout. First let us
review briefly some of the latter, some of those biological
considerations which lead us to regard thoughtfully the problem of
the future evolution of man and his societies.

As with other species of animals, each of us comes into the world
equipped with a physical constitutio
