When the ¢egiha divided at the mouth of the Ohio, the ancestors of the Osage and Kansa accompanied the main Omaha body up the Mississippi to the mouth of Osage river. There the Osage separated from the group, ascending the river which bears their name. They were distinguished by Marquette in 1673 as the "Ouchage" and "Autrechaha," and by Penicaut in 1719 as the "Huzzau," "Ous," and "Wawha." According to Croghan, they were, in 1759, on "White creek, a branch of the Mississippi," with the "Grand Tuc;" but"White creek" (or White water) was an old designation for Osage river, and "Grand Tuc" is, according to Mooney, a corruption of "Grandes Eaux," or Great Osage; and there is accordingly no sufficient reason for supposing that they returned to the Mississippi. Toward the close of the eighteenth century the Osage and Kansa encountered the Comanche and perhaps other Shoshonean peoples, and their course was turned southward; and in 1817, according to Brown, the Great Osage and Little Osage were chiefly on Osage and Arkansas rivers, in four villages. In 1829 Porter described their country as beginning 25 miles west of the Missouri line and running to the Mexican line of that date, being 50 miles wide; and he gave their number as 5,000. According to Schoolcraft, they numbered 3,758 in April, 1853, but this was after the removal of an important branch known as Black Dog’s band to a new locality farther down Verdigris river. In 1850 the Osage occupied at least seven large villages, besides numerous small ones, on Neosho and Verdigris rivers. In 1873, when visited by Dorsey, they were gathered on their reservations in what is now Oklahoma. In 1890 they numbered 158. The Kansa remained with the Up-stream People in their gradual ascent of the Missouri to the mouth of the Kaw or Kansas, when they diverged westward; but they soon came in contact with inimical peoples, and, like the Osage, were driven southward. The date of this divergence is not fixed, but it must have been after 1723, when Bourgmont mentioned a large village of "Quans" located on a small river flowing northward thirty leagues above Kaw river, near the Missouri. After the cession of Louisiana to the United States, a treaty was made with the Kansa Indians, who were then on Kaw river, at the mouth of the Saline, having been forced back from the Missouri by the Dakota; they then numbered about 1,500 and occupied about thirty earth lodges. In 1825 they ceded their lands on the Missouri to the Government, retaining a reservation on the Kaw, where they were constantly subjected to attacks from the Pawnee and other tribes, through which large numbers of their warriors were slain. In 1846 they again ceded their lands and received a new reservation on Neosho river in Kansas. This was soon overrun by settlers, when another reservation was assigned to them in Indian Territory, near the Osage country. By 1890 their population was reduced to 214.
