It is quite evident that during the past two or three centuries great changes have taken place in the locations of the tribes which were discovered occupying the region west of the Mississippi by the first Europeans to penetrate the vast wilderness. Thus the general movement of many Siouan tribes has been westward, that of some Algonquian groups southward from their earlier habitats, and the Caddoan appear to have gradually gone northward. It resulted in the converging of the tribes in the direction of the great prairies occupied by the vast herds of buffalo which served to attract the Indian. Until the beginning of this tribal movement it would seem that a great region eastward from the base of the Rocky Mountains, the rolling prairie lands, was not the home of any tribes but was solely the range of the buffalo and other wild beasts, which existed in numbers now difficult to conceive. THE BUFFALO. (_Bison americanus_.) With the practical extermination of the buffalo in recent years, and the rapid changes which have taken place in the general appearance of the country, it is difficult to picture it as it was two or more centuries ago. While the country continued to be the home of the native tribes game was abundant, and the buffalo, in prodigious numbers, roamed over the wide region from the Rocky Mountains to near the Atlantic. It is quite evident, and easily conceivable, that wherever the buffalo was to be found it was hunted by the people of the neighboring villages, principally to serve as food. But the different parts of the animal were made use of for many purposes, and, as related in an early Spanish narrative, one prepared nearly four centuries ago, when referring to "the oxen of Quivira ... Their masters have no other riches nor substance: of them they eat, they drink, they apparel, they shooe themselves: and of their hides they make many things, as houses, shooes, apparell and ropes: of their bones they make bodkins: of their sinews and haire, threed: of their hornes, maws, and bladders, vessels: of their dung, fire: and of their calves-skinnes, budgets, wherein they drawe and keepe water. To bee short, they make so many things of them as they neede of, or as many as suffice them in the use of this life." (Gomara, (1), p. 382.) A crude engraving of a buffalo made at that time is reproduced in figure 1. [Illustration: FIG. 1.--The buffalo of Gomara, 1554] The preceding account describes the customs of the people then living in the southern part of the region treated in the present sketch, either a Caddoan or a neighboring tribe or group, and it suggests another reference to the great importance of the buffalo, but applying to the tribes of the north more than three centuries later.
