There have been drifts from east to west and west to east, from north to south and back again, drifts that have criss-crossed one another, and drifts colliding and recoiling and caroming off in new directions. From Central Europe the Aryans have drifted into Asia, and from Central Asia the Turanians have drifted across Europe. Asia has thrown forth great waves of hungry humans from the prehistoric "round-barrow" "broad-heads" who overran Europe and penetrated to Scandinavia and England, down through the hordes of Attila and Tamerlane, to the present immigration of Chinese and Japanese that threatens America. The Phoenicians and the Greeks, with unremembered drifts behind them, colonised the Mediterranean. Rome was engulfed in the torrent of Germanic tribes drifting down from the north before a flood of drifting Asiatics. The Angles, Saxons, and Jutes, after having drifted whence no man knows, poured into Britain, and the English have carried this drift on around the world. Retreating before stronger breeds, hungry and voracious, the Eskimo has drifted to the inhospitable polar regions, the Pigmy to the fever-rotten jungles of Africa. And in this day the drift of the races continues, whether it be of Chinese into the Philippines and the Malay Peninsula, of Europeans to the United States or of Americans to the wheat- lands of Manitoba and the Northwest. Perhaps most amazing has been the South Sea Drift. Blind, fortuitous, precarious as no other drift has been, nevertheless the islands in that waste of ocean have received drift after drift of the races. Down from the mainland of Asia poured an Aryan drift that built civilisations in Ceylon, Java, and Sumatra. Only the monuments of these Aryans remain. They themselves have perished utterly, though not until after leaving evidences of their drift clear across the great South Pacific to far Easter Island. And on that drift they encountered races who had accomplished the drift before them, and they, the Aryans, passed, in turn, before the drift of other and subsequent races whom we to-day call the Polynesian and the Melanesian.
