In any process of aggression of the native American race on the older area of the Eskimo, some intermixture of blood would naturally follow. The slaughter of the males in battle, and the capture of women and children, everywhere leads to a like result; and this seems the simplest solution of the problem of the southern brachycephalic, and the northern dolichocephalic type of head among native American races. When the sites of the ancient colonies of Greenland were rediscovered and visited by the Danes, they imagined they could recognise in the physiognomy of some of the Eskimo who still people the shores of Davis Straits, traces of admixture between the old native and the Scandinavian or Icelandic blood. Of the Greenland colonies the Eskimo had perpetuated many traditions, referring to the colonists under the native name of _Kablunet_. But of the language that had been spoken among them for centuries, the fact is highly significant that the word _Kona_, used by them as a synonym for woman, is the only clearly recognised trace. This is worthy of note, in considering the distinctive character of the Eskimo language, and its comparison with the Indian languages of the North American continent. It has the feature common to nearly all the native languages of the continent north of the Mexican Gulf in the composite character of its words; so that an Eskimo verb may furnish the equivalent to a whole sentence in other tongues. But what is specially noteworthy is that, while the Huron-Iroquois, the Algonkin, and other Indian families of languages have multiplied widely dissimilar dialects, Dr. Henry Rink has shown that the Eskimo dialects of Greenland or Labrador differ slightly from those of Behring Strait; and the congeners of the American Eskimo, who have overflowed into the Aleutian Islands, and taken possession of the north-eastern region of Asia, perpetuate there nearly allied dialects of the parent tongue.[8] The Alaskan and the Tshugazzi peninsulas are in part peopled by Eskimo; the Konegan of Kudjak Island belong to the same stock; and all the dialects spoken in the Aleutian Islands, the supposed highway from Asia to America, betray in like manner the closest affinities to the Arctic Mongolidæ of the New World. They thus appear not only to be contributions from the New World to the Old, but to be of recent introduction there. If the cave-dwellers of Europe’s palæolithic era found their way as has been suggested, in some vastly remote age, either by an eastern or a western route to the later home of the Arctic Eskimo, it is in comparatively modern centuries that the tide of migration has set westward across the Behring Strait, and by the Aleutian Islands, into Asia.
