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.

Man early discovered death.  As soon as his evolution permitted, he made himself better devices for killing than the old natural ones of fang and claw.  He devoted himself to the invention of killing devices before he discovered fire or manufactured for himself religion.  And to this day, his finest creative energy and technical skill are devoted to the same old task of making better and ever better killing weapons.  All his days, down all the past, have been spent in killing.  And from the fear-stricken, jungle-lurking, cave-haunting creature of long ago, he won to empery over the whole animal world because he developed into the most terrible and awful killer of all the animals.  He found himself crowded.  He killed to make room, and as he made room ever he increased and found himself crowded, and ever he went on killing to make more room.  Like a settler clearing land of its weeds and forest bushes in order to plant corn, so man was compelled to clear all manner of life away in order to plant himself.  And, sword in hand, he has literally hewn his way through the vast masses of life that occupied the earth space he coveted for himself.  And ever he has carried the battle wider and wider, until to-day not only is he a far more capable killer of men and animals than ever before, but he has pressed the battle home to the infinite and invisible hosts of menacing lives in the world of micro-organisms.
