In tropical Africa,
to which the Negro is adapted by many centuries of natural selection,
his expectation of life might be much longer than that of the white man.
In the United States he is much less "fit," in the Darwinian sense.
In rural districts of the South, according to C. W. Stiles, the annual
typhoid death rate per 100,000 population is:
_Whites_ _Negroes_
Males 37.4 75.3
Females 27.4 56.3
These figures again show, not alone the greater intelligence of the
white in matters of hygiene, but probably also the greater inherent
resistance of the white to a disease which has been attacking him for
many centuries. Biologically, North America is a white man's country,
not a Negro's country, and those who are considering the Negro problem
must remember that natural selection has not ceased acting on man.
From the foregoing different kinds of evidence, we feel justified in
concluding that the Negro race differs greatly from the white race,
mentally as well as physically, and that in many respects it may be said
to be inferior, when tested by the requirements of modern civilization
and progress, with particular reference to North America.
We return now to the question of intermarriage.
