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] In the progress of early discovery and settlement, striking views were presented of savage life among the Red Men inhabiting the Atlantic coast; but later researches along the banks of the Mississippi and its tributaries, and by the great Canadian lakes, exhibited this people under a still more remarkable aspect. The most prominent among the natives of the interior for power, policy, and courage, were the Iroquois or Five Nations.[227] Their territory extended westward from Lake Champlain, to the farthest extremity of Ontario, along the southern banks of the St. Lawrence, and of the Great Lake. Although formed by the alliance of five independent tribes, they always presented a united front to their foes, whether in defense or aggression. Their enemies, the Algonquins, held an extensive domain on the northern bank of the St. Lawrence; these last were at one time the masters of all that portion of America, and were the most polished and mildest in manners of the northern tribes. They depended altogether for subsistence on the produce of the chase, and disdained those among their neighbors who attempted the cultivation of the soil. The Hurons[228] were a numerous nation, generally allied with the Algonquins, inhabiting the immense and fertile territory extending westward to the Great Lake, from which they take their name: they occupied themselves with a rude husbandry, which the fertile soil of the west repaid, by affording them an abundant subsistence; but they were more effeminate and luxurious than their neighbors, and inferior in savage virtue and independence. The above-named nations were those principally connected with the events of Canadian history.
