Physically the Eskimo is a Mongol and Asiatic.
The Eskimos of the Atlantic are not only easily distinguished from
the tribes of American aborigines which lie to the south or west
of them, and with which they come in contact, but they stand in
strong contrast and opposition to them--a contrast and opposition
exhibited equally in appearance, manners, language, and one which
has had full justice done to it by those who have written on the
subject.
It is not so with the Eskimos of Russian-America, and the parts
that look upon the Pacific. These are so far from being separated
by any broad and trenchant line of demarcation from the proper
Indians or the so-called red race, that they pass gradually
into it, and that in respect to their habits, manner, and
appearance, equally. So far is this the case that he would be a
bold man who should venture, in speaking of the southern tribes
of Russian-America, to say here the Eskimo area ends and here a
different area begins.
