This conclusion, to which Mr. Schoolcraft had arrived, that the ancient Alleghans or Tallegwi were the mound builders of the Ohio Valley is being sustained by later investigators, and seems to have become an accepted opinion among those of highest authority. The Alleghans, moreover, are being identified with the Cherokees of later times, in whom their race, once supposed to be extinct, has apparently survived; while the fact, long suspected, that the Cherokee language is of the Iroquois family is being proved by the latest studies. According to Indian tradition, the Alleghans were driven from their ancient seats, long ago, by a combination against them of the Lenape (Delawares) and the Mengwe (Iroquois). The route of their migrations is being traced by the character of the mounds which they built, and of the remains gathered from the mounds. "The general movement [of retreat before the Iroquois and Lenape] ... must have been southward, ... and the exit of the Ohio mound-builders was, in all probability, up the Kanawah Valley on the same line that the Cherokees appear to have followed in reaching their historical locality. ... If the hypothesis here advanced be correct, it is apparent that the Cherokees entered the immediate valley of the Mississippi from the northwest, striking it in the region of Iowa." _C.
