To my mind the force of argument seems to tend the other way. If a race of men lived on the face of the globe for 100,000 years so utterly unprogressive as these cave men, incapable of discovering the use of metals for themselves during that long period, or even of adopting them from Egypt and the East, where bronze certainly, and most probably iron, were known at least 6000 or 7000 years ago; if this people used flint and bone during all this period, is it likely that they would adopt new-fangled implements and new customs the first time they were presented to them? The Esquimaux have been familiar with the Danish settlers in Greenland for some centuries, and could easily have procured improved implements and many of the advantages of civilization had they been so inclined. They have not been changed a hair's-breadth by the influence of the stranger. The red man of North America has been in contact with the white man for centuries now. Has he changed, or can he change? In Alaska, and to the northward of Vancouver's Island, there is a race of savages, called Hydahs, with all the artistic tastes and faculties of the men of the Dordogne caves, and with about the same degree of civilization.[22] All these are dying out, and may soon disappear, but they present at this day exactly the same phenomenon as we see in the south of France, say 10,000 years ago. They have been exterminated in all the civilized parts of Europe by the progressive Aryan races who have usurped their places; and it seems only too certain that, like them, their American kindred must perish before the growing influence of the white man, but they cannot change. In so far as we can judge from such facts as are before us, if any family of this old people still lurked among our hills or on any rocky island, their habits, or customs, and their implements, would be as like those of the cave men as those of the Esquimaux or Alaska savages are at the present day. It appears most unphilosophical to apply to those people the principles of progress that are found among the higher races of mankind, and to represent them as eagerly seizing on any improvement offered them, and abandoning their old faith and their old habits at the bidding of any wandering navigator that visited their shores.
