Two hundred years ago the Valley of the Mississippi, and the regions east of it, were occupied by two great families of Indians, the Iroquois and the Algonquins, each divided into separate tribes. Between these two families there was a radical difference of language. The Indians of New England were Algonquins. The Iroquois dwelt chiefly in New York, and around Lake Erie, from Niagara to Detroit, although separate communities of the group to which they immediately belonged were found in other places, such as the Dacotahs and Winnebagoes at the West, and the isolated Tuscaroras of the Carolinas. Mr. Lewis H. Morgan, who has discussed “Indian Migrations” in several interesting papers printed in the North American Review, thinks the Iroquois were separated very early from the same original stem which produced the great Dacotah family. The Algonquins were spread most widely over the country when it was first visited by Europeans. Among all these Indians there was a tradition that their ancestors came from a distant region in the Northwest, and this tradition is accepted as true by those who have studied them most carefully. Mr. Morgan supposes they came across the continent, and estimates that not less than a thousand years must have passed between the departure of the various groups of the Algonquin family from a common centre in the northwest and the condition in which they were found two hundred years ago. When Europeans began to explore North America, this family had become divided into several branches, and each of these branches had a modified form of the common language, which, in turn, had developed several dialects. A long period was required to effect so great a change; but, whatever estimate of the time may be accepted, it seems to be a fact that the Algonquins came to the Mississippi Valley long after the Mound-Builders left it, and also later than the Iroquois or Dacotah family. That the Iroquois preceded the Algonquins at the East appears to be indicated by the relative position of the two families in this part of the country. Mr. Parkman, in his work on “The Jesuits in North America,” describes it as follows: “Like a great island in the midst of the Algonquins lay the country of tribes speaking the generic tongue of the Iroquois.” There is no trace or probability of any direct relationship whatever between the Mound-Builders and the barbarous Indians found in the country. The wild Indians of this continent had never known such a condition as that of the Mound-Builders. They had nothing in common with it. In Africa, Asia, and elsewhere among the more uncultivated families of the human race, there is not as much really _original_ barbarism as some anthropologists are inclined to assume; but there can be no serious doubt that the wild Indians of North America were original barbarians, born of a stock which had never, at any time, been either civilized or closely associated with the influences of civilization.
