With regard to the much-vexed question of the origin of the Indian races, M. de Bourbourg offers no theory. In his view, the evidence from language establishes no certain connection between the Indian tribes and any other race whatever; though, as he justly remarks, the knowledge of the languages of the Northeast of Asia and of the interior of America is yet very limited, and more complete investigations must be waited for before any very satisfactory conclusions can be attained. The similarity of the Indian languages points without doubt to a common origin, while their variety and immense number are indications of a high antiquity; for who can estimate the succession of years necessary to subdivide a common tongue into so many languages, and to give birth out of a savage or nomadic life to a civilization like that of the Aztecs?
In the passage of man from one hemisphere to another he sees no difficulty; as, without considering Behring's Strait, the voyage, from Mantchooria, or Japan, following the chain of the Koorile and the Aleutian Isles, even to the Peninsula of Alaska, would be an enterprise of no great hazard.
The traditions of the Indian tribes, as well as their monumental inscriptions, point to an Eastern origin. From whatever direction the particular tribe may have emigrated, they always speak of their fathers as having come from the rising of the sun. The Quiche, as well as the Chippeway traditions, allude to the voyages of their fathers from the East, from a cold and icy region, through a cloudy and wintry sea, to countries as cold and gloomy, from which they again turned towards the South.
Without committing himself to a theory, M. de Bourbourg supposes that one race--the Quiche--has passed through the whole North American continent, erecting at different stages of its civilization those gigantic and mysterious pyramids, the _tumuli_ of the Mississippi Valley,--of whose origin the present Northern Indian tribes have preserved no trace, and for whose erection no single American tribe now would have the wealth or the superfluous labor. This race was continually driven towards the South by more savage tribes, and it at length reached its favorite seats and the height of its civilization in Central America. In comparing the similar monuments of Southern Siberia, and the dates of the immigration to the Aztec plateau, with those of the first movements of the Huns and the great revolutions in Asia, an indication is given, worthy of being followed up by the ethnologist, of the Asiatic origin of the Central American tribes. The traditions, monuments, customs, mythology, and astronomic systems all point to a similar source.
