_Arapahoes and Cheyennes of the South._--These tribes are native to the section of country now inhabited by them. The Arapahoes number at the present time 1,500, and the Cheyennes 2,000. By the treaty of 1867, made with these Indians, a large reservation was provided for them, bounded on the north by Kansas, on the east by the Arkansas River, and on the south and west by the Red Fork of the Arkansas. They have, however, persisted in a refusal to locate on this reservation; and another tract, containing 4,011,500 acres, north of and adjoining the Kiowa and Comanche reservation, was set apart for them by Executive order of Aug. 10, 1869. By act of May 29, 1872, the Secretary of the Interior was authorized to negotiate with these Indians for the relinquishment of their claim to the lands ceded to them by the said treaty, and to give them in lieu thereof a "sufficient and permanent location" upon lands ceded to the United States by the Creeks and Seminoles in treaties made with them in 1866. Negotiations to the end proposed were duly entered into with these tribes unitedly; but, in the course of such negotiations, it has become the view of this Office that the tribes should no longer be associated in the occupation of a reservation. The Arapahoes are manifesting an increasing disinclination to follow further the fortunes of the Cheyennes, and crave a location of their own. Inasmuch as the conduct of the Arapahoes is uniformly good, and their disposition to make industrial improvement very decided, it is thought that they should now be separated from the more turbulent Cheyennes, and given a place where they may carry out their better intentions without interruption and without the access of influences tending to draw their young men away to folly and mischief. With this view a contract, made subject to the action of Congress, was entered into between the Commissioner of Indian Affairs and the delegation of the Arapaho tribe which visited Washington during the present season (the delegation being fully empowered thereto by the tribe), by which the Arapahoes relinquish all their interest in the reservation granted them by the treaty of 1867, in consideration of the grant of a reservation between the North Fork of the Canadian River and the Red Fork of the Arkansas River, and extending from a point ten miles east of the ninety-eighth to near the ninety-ninth meridian of west longitude. Should this adjustment of the question, so far as the Arapahoes are concerned, meet the approval of Congress, separate negotiations will be entered into with the Cheyennes, with a view to obtaining their relinquishment of the reservation of 1867, and their location on some vacant tract within the same general section of the Indian Territory.
