Now we must again form a mental picture of Neolithic Europe— after it had been for a long time in the possession of the Turanian tribes, the first band of Aryan invaders make their appearance. They must have appeared somewhere near the south-eastern confines of Europe, but they pressed forward to the western portion. They firmly seated themselves in the western and central parts of Europe, driving out the Turanian tribes who had so long possessed the land. They were themselves still in the Neolithic stage of culture. But they probably did not long antedate the knowledge of metals. Mr. Dawkins thinks that it caught up with them before they arrived in Britain, and that they are the ones who introduced bronze into that island. The Aryan tribe, who thus made their appearance in Europe, are identified as the Celts of history. The Neolithic Age thus drew to its close, but not all at once. It disappeared first in the southern portion of Europe—from Greece and Italy; but it lingered to a far later date in the north: among the scattered tribes of Turanian people it would still assert its sway. Even after metals were introduced, the cheapness and abundance of stone would cause it to be used, among the poorer people at least. But finally this culture gives way to a higher one in Europe—though it still survived in portions of Asia, the Isles of the Pacific, and in America. We can but reflect on the difference between the two ages of stone. The former ends amidst Arctic scenes—and, in the darkness that ensues, ages pass before we again detect the presence of man. The Neolithic closes gradually, everywhere giving way to a higher culture. We must not forget that our present civilization owes much to our far away Neolithic ancestors. When we reflect on the difficulties that had to be overcome before animals could be profitably held in a domestic state, or cultivation of the earth made profitable, we almost wonder that they succeeded in either direction. Aside from these, we turn to them for the origin of trade, navigation, and mining. No inconsiderable part of the battle of civilization had thus been won. REFERENCES The manuscript of this chapter was submitted to Prof. Chas. Rau, of the Smithsonian Institution, for criticism. The Cave-men were, undoubtedly, considerably in advance of the Men of the Drift. If we regard the two as but one race of men, then the statement is not true. We have, however, given our reasons for considering the Cave-men as a different race. Hence the statement made above.
