inhabitants. Apart from the Europeans and Africans who have poured in since the fifteenth century, the native Americans in general might be, as has often been said, of one race. Not that they are all alike, but their differences in stature, form of skull, feature, and complexion, though considerable, seem variations of a secondary kind. It is not as if several races had formed each its proper type in its proper region, but as if the country had been peopled by migrating tribes of a ready-made race, who had only to spread and acclimatise themselves over both tropical and temperate zones, much as the European horses have done since the time of Columbus, and less perfectly the white men themselves. The race to which most anthropologists refer the native Americans is the Mongoloid of East Asia, who are capable of accommodating themselves to the extremest climates, and who by the form of skull, the lightbrown skin, straight black hair, and black eyes, show considerable agreement with the American tribes. Figs. 41 and 42 represent the wild hunting-tribes of North America in one of the finest forms now existing, the Colorado Indians, while in Fig. 43 the Cauixana Indians may stand as examples of the rude and sluggish forest-men of Brazil. While tribes of America and Asia may thus be of one original stock, we must look cautiously at theories as to the ocean and island routes by which Asiatics may have migrated to people the New World. It is probable that man had appeared there, as in the Old World, in an earlier geological period than the present, so that the first kinship between the Mongols and the North American Indians may go back to a time when there was no ocean between them. What looks like later communication between the two continents, is that the stunted Eskimo with their narrow roof-topped skulls may be a branch of the Japanese stock, while there are signs of the comparatively civilized Mexicans and Peruvians having in some way received arts and ideas from Asiatic nations. We come last to the white men, whose nations have all through history been growing more and more dominant intellectually, morally, and politically on the earth. Though commonly spoken of as one variety of mankind, it is plain that they are not a single uniform race, but a varied and |
