he careful or fair-minded observer), and the
differentiation of races by selection and environment has been so stated
as to prove itself. Greater emphasis has been placed upon environment as
a factor in ethnic development, and what has been called "the vulgar
theory of race," as accounting for progress and culture, has been
relegated to the limbo of exploded dogmas. One of the most perspicuous
and forceful presentations of these modern conclusions of anthropology
is found in the volume above quoted, a book which owes its origin to a
Boston scholar.

Proceeding then upon the firm basis laid down by science and the
historic parallel, it ought to be quite clear that the future American
race--the future American ethnic type--will be formed of a mingling, in
a yet to be ascertained proportion, of the various racial varieties
which make up the present population of the United States; or, to extend
the area a little farther, of the various peoples of the northern
hemisphere of the western continent; for, if certain recent tendencies
are an index of the future it is not safe to fix the boundaries of the
future United States anywhere short of the Arctic Ocean on the north and
the Isthmus of Panama on the south. But, even with the continuance of
the present political divisions, conditions of trade and ease of travel
are likely to gradually assimilate to one type all the countries of the
hemisphere. Assuming that the country is so well settled that no great
disturbance of ratios is likely to result from immigration, or any
serious conflict of races, we may safely build our theory of a future
American race upon the present population of the country. I use the word
"race" here in its popular sense--that of a people who look
substantially alike, and are moulded by the same culture and dominated
by the same ideals.

By the eleventh census, the ratios of which will probably not be changed
materially by the census now under way, the total population of the
United States was about 65,000,000, of which about seven million were
black and colored, and something over 200,000 were of Indian blood. It
is then in the three broad types--white, black and Indian--that the
future American race will find the material for its formation. Any dream
of a pure white race, of the Anglo-Saxon type, for the United States,
may as well be abandoned as impossible, even if desirable. That such
future race will be predominantly white may well be granted--unless
