They are a wandering nation, inhabit an open country, and raise a great number of horses, which they barter to the Ricaras, Mandans, etc, for articles of European manufactory. They are a well-disposed people, and might be readily induced to visit the trading establishments on the Missouri. From the animals their country produces, their trade would no doubt become valuable. These people again barter a considerable proportion of the articles they obtain from the Menetares, Ahwahhaways, Mandans, and Ricaras to the Dotames and Castapanas.... Neither these people ("Kiawas"), the Wetepahatoes, nor the Chyennes have any idea of exclusive right to the soil (_Lewis and Clark, 1_). The Dotames and Castapanas (for Castahanas) here mentioned are described as living back of the Kiowa, between the head streams of the North Platte and the Yellowstone, and were probably bands of the Shoshoni. From this it appears that besides being well supplied with horses, with which they carried on a profitable trade at this period with the tribes on the Missouri, the Kiowa also acted as the trading medium between these tribes and others living in the mountains beyond the Kiowa. The officer suggests the mouth of Cheyenne river as the most suitable place to establish a trading post for them. The Crows are described as having then the same wars and friendships as the Kiowa, excepting that they were at war with the Arikara as well as with the Dakota (_Lewis and Clark, 2_). The Comanche are described at this period (1805) under the name of the "La Playes" division of "Aliatans" or "Snake Indians," as inhabiting the plains from the headwaters of the Arkansas, and including the sources of Red river, and extending from the mountains eastward indefinitely. They were a wandering people, claiming no particular boundaries, and, although possessing no guns, were brave and warlike. Their country abounded in wild horses, besides great numbers which they raised themselves (_Lewis and Clark, 3_). In his volume published a few years later the explorer, Zebulon M. Pike, states that the Kiowa, estimated by him to number 1,000 men, had in 1803 been driven by the Dakota into the mountains on the heads of the Platte and Arkansas and north of the Comanche, where they were then wandering. They owned immense herds of horses, were armed with bows, arrows, and lances, hunted the buffalo, and were at war with the Dakota, Pawnee, and "Tetau" (here meaning the Ute). In another place he mentions both Ute and Kiowa as living in the mountains of northern Mexico--the present Colorado and New Mexico--the former being more civilized from contact with the Spaniards. He speaks also of meeting, in 1807, a party of Kiowa and Comanche returning from a trading expedition to the Mandan (_Pike, 1_). EXPLANATION OF "ALIATAN" AND "TETAU"
