There is something almost mysterious in the total difference between the languages of the Old and New World.[223] All the tongues of civilized nations spring from a few original roots, somewhat analogous to each other; but it would seem that, among wandering tribes, dispersed over a vast extent of country, carrying on but little intercourse, and having no written record or traditionary recital to preserve any fixed standard, language undergoes a complete change in the course of ages. The great varieties of tongues in America, and their dissimilarity to each other, tend to confirm this supposition.
In various parts of America, remains are found which place beyond a doubt the ancient existence of a people more numerous, powerful, and civilized than the present race of Indians; but the indications of this departed people are not such as to bespeak their having been of very remote antiquity: the ruined cities of Central America, concealed by the forest growth of centuries, and the huge mounds of earth[224] in the Valley of the Mississippi and upon the table-lands of Mexico, their dwellings and mausoleums, although long swept over by the storm of savage conquest, afford no proofs of their having existed very far back into those dark ages when the New World was unknown to Europe. The history of these past races of men will probably forever remain a sealed book, but there is no doubt that a great population once covered those rich countries which the first English visitors found the wild hunting-grounds for a few savage tribes.[225] Probably the existing race of Red Men were the conquerors and exterminators of the feeble but civilized aboriginal nations, and as soon as they possessed the land they split into separate and hostile communities, waging perpetual war with each other so as constantly to diminish their numbers.
Far up the Mississippi and the Missouri the exploration of the country brings to light incontestable proofs of the existence of the mysterious aboriginal race: wells artificially walled, and various other structures for convenience or defense, are frequently seen; ornaments of silver, copper, and even brass are found, together with various articles of pottery and sculptured stone; sepulchers filled with vast numbers of human bones have often been discovered, and human bodies in a state of preservation are sometimes exhumed. On one of these the hair was yellow or sandy, and it is well known that an unvarying characteristic of the present red race is the lank black hair. A splendid robe of a kind of linen, made apparently from nettle fibers, and interwoven with the beautiful feathers of the wild turkey, encircled this long-buried mummy. The number and the magnitude of the mounds bear evidence that the concurrent labors of a vast assembly of men were employed in their construction.[226]
