One hundred thousand years ago the decimated tribes of the red race were fighting with their backs to the retreating ice of the last glacier, and when the land passage to the West, over the Bering isthmus, became passable, these tribes were not slow in forsaking the inhospitable shores of the Asiatic continent. It is eighty-five thousand years since the last of the pure red men departed from Asia, but the long struggle left its genetic imprint upon the victorious yellow race. The northern Chinese peoples, together with the Andonite Siberians, assimilated much of the red stock and were in considerable measure benefited thereby.
