"In this direction, then, a North American germ of population may have entered the continent from Asia, diffused itself over the Northwest, and ultimately reached the valleys of the Mississippi, and penetrated to southern latitudes by a route to the east of the Rocky Mountains. Many centuries may have intervened between the first immigration and its coming in contact with races of the southern continent; and philological and other evidence indicates that if such a northwestern immigration be really demonstrable, it is one of very ancient date. But so far as I have been able to study the evidence, much of that hitherto adduced appears to point the other way. * * *
"With Asiatic Esquimaux thus distributed along the coast adjacent to the dividing sea; and the islands of the whole Aleutian group in the occupation of the same remarkable stock common to both hemispheres: The only clearly recognizable indications are those of a current of migration setting toward the continent of Asia, the full influence of which may prove to have been more comprehensive than has hitherto been imagined possible. * * *"
Grote, 1877:[239] Regards the Eskimo as the original inhabitants of North America and believes they extended down to 50° in the eastern and 60° in the western part of the continent.
Krause, 1883:[240] "Ueberblickt man nun die gegenwärtige Verbreitung der Eskimos in Asien, so wird man der Ansicht von Dall und Nordenskiöld beistimmen, dass die asiatischen Eskimo aus Amerika eingewandert sind und nicht, wie Steller, Wrangell, und andere vermutheten, zurückgebliebene Reste einer ehemals zahlreicheren, nach Amerika hinübergezogenen Bevölkerung. Immerhin würde durch die Annahme eines amerikanischen Ursprunges der jetzigen Eskimobevölkerung die Möglichkeit früherer Wanderungen in entgegengesetzter Richtung nicht ausgeschlossen sein, nur giebt die gegenwärtige Verbreitung keinen Anhalt für eine solche, und historische Beweise fählen."
Ray, 1885:[241] "Of their origin and descent we could get no trace, there being no record of events kept among them. * * *
"That they have followed the receding line of ice, which at one time capped the northern part of this continent, along the easiest lines of travel is shown in the general distribution of a similar people, speaking a similar tongue, from Greenland to Bering Strait; in so doing they followed the easiest natural lines of travel along the watercourses and the seashore, and the distribution of the race to-day marks the routes traveled. The seashore led them along the Labrador and Greenland coasts; Hudson Bay and its tributary waters carried its quota towards Boothia Land; helped by Back's Great Fish River, the Mackenzie carried them to the northwestern coast, and down the Yukon they came to people the shores of Norton Sound and along the coast to Cape Prince of Wales. They occupied some of the coast to the south of the mouth of the Yukon, and a few drifted across Bering Strait on the ice, and their natural traits are still in marked contrast with their neighbors, the Chuckchee. They use dogs instead of deer, the natives of North America having never domesticated the reindeer, take their living from the sea, and speak a different tongue. Had the migration come from Asia it does not stand to reason that they would have abandoned the deer upon crossing the straits."
