When the Pawnees left Louisiana, the Caddos certainly, and perhaps the Keechies and the Tawaconies, were left behind, and for a very long time lived in and near what is now Caddo Parish, Louisiana, where they were at the time of the Louisiana Purchase. Geographical names in this region indicate that their residence there was a long one, and Caddo Lake, Caddo Fork, Caddo Gap and a town named Keatchie, still bear testimony of the former occupants of the soil. From there the Caddos moved up to the Brazos River in Texas. They have always kept up a close intimacy with the Wichitas.
Perhaps it was during the sojourn of the Pawnees on the western borders of Louisiana and Arkansas, though it may have been much earlier, that the Skidi and the Arickaras, either as a single tribe, or as already divided into two separate bands, left the Pawnees and moved north and northwest. There appears to be reason for supposing that for a while this section of the tribe lived on the Red River, the Canadian and the Arkansas, and it is quite certain that sometimes they went as far east as the banks of the Mississippi near where St. Louis now is; but their permanent home, since they have been known to the whites, was on the Platte and the Loup rivers in Nebraska.
The Pawnees with the Wichitas moved northwest into what is now the Indian Territory and southern Kansas, where they separated, the latter turning off to the south, and living at various times on the Canadian and Red rivers and near the Wichita Mountains, while the Pawnees proper slowly continued their march northward and westward, residing for a time on the Arkansas and Solomon, the Republican and Platte rivers. Here they again met the Skidi.
It is impossible to conjecture when this settlement in the northern country took place, but it was certainly long ago. Mr. Dunbar has pointed out that "_O-küt-ut_ and _oku´-kat´_ signify strictly above and below (of a stream) respectively. Now their villages have usually been situated upon the banks of the Platte, the general course of which is from west to east. Hence each of these words has acquired a new meaning, _i. e._, west and east." In the same way _Pük-tïs´-tu_--toward the Omahas, has come to mean north; and _Ki´ri-ku´ruks-tu_--toward the Wichitas, to mean south. The coining of such words points to a long sojourn by the Pawnees in the region of the Platte. It is interesting to note that the Omahas have never in historic times lived north of the Pawnees, but always east of them, though we know that long ago they did live to the north.
