made of war eagle's feathers was dependent." (James, (1), I, p. 272.) CADDOAN TRIBES. The ancient habitat of the many small tribes which evidently later became confederated, thus forming the principal groups of this linguistic stock, was in the southwest, whence the Pawnee and Arikara, and those gathered under the name of the Wichita, moved northward. The Caddo proper, the name of a tribe later applied to the confederated group of which they formed the principal member, formerly occupied the valley of the Red River of Louisiana, the many villages of the several tribes being scattered along the banks of that stream and of its tributaries in northern Louisiana, southwestern Arkansas, and eastern Texas. Although usually included in the same linguistic group with the Pawnee, Arikara, Wichita, and others, several notable authorities are inclined to regard the Caddo as constituting a separate and distinct linguistic group. This may be established and recognized in the future. PAWNEE. Soon after the transfer of Louisiana to the United States Government several expeditions were sent out to explore the newly acquired domains and to discover the native tribes who claimed and occupied parts of the vast territory. Of these parties, that led by Capts. Lewis and Clark was the most important, but of great interest was the second expedition under command of Lieut. Z. M. Pike, which traversed the country extending from the Mississippi to the Rocky Mountains, and reached the Pawnee villages near the North Platte during the month of September, 1806. How long the Pawnee had occupied that region may never be determined, but they had evidently migrated from the southwest, probably moving slowly, making long stops on the way. As a tribe they were known to the Spaniards as early as the first half of the sixteenth century, and appear to have been among the first of the plains tribes to be visited by French and Spanish traders.
