The tract herein described included only a portion of what was subseiiuently 

 recognized as Sioux territory. 



These Indians subsequently claimed to own country on the N. side of the Mis- 

 souri river also, and l)y treaty of July 27, 1866, ceded it. This treaty was 

 never ratified, and their relations with the governnifut remained unsettled 

 until, by Executive order of Apr. 12, 1870, they were assigned a reserve in 

 lieu of the country assigned them by Fort Laramie treaty of 1851. This 

 reserve, with the exception of a small tract ou the N. side of Missouri river, 

 comprised part of their recognized territory by the Fort Laramie treaty of 

 1851, the remainder of that tract being considered as ceded. 



The Assiuiboin ceded this country by treaty in 1866, which treaty was never 

 ratified, but by their acceptance of a home on the reserve for the Blackfoot, 

 Blood, Gros Ventre, Piegan, and River Crow, established Apr. 15, 1874, they 

 practically relinquished it. 



See the third article of the treaty of Oct. 17, 1855, which designates this country See 398, 399 

 as a common hunting ground for various tribes. 



A portion o this tract was ceded by treaty of May 7, 1868. Another portion See 619, 635, 

 was relinquished by agreement of .lune 12, 1880, and the remainder consti- 517 



tutes a portion of their present reserve. 



Their W. and S. boundaries as herein defined follow the Rocky monntain.s from 

 the source of N. fork of Platte river to the head waters of the Arkansas and 

 thence down the Arkansas to the crossing of the .'^anta Fc trail. This treaty 

 evidently contemplated that their southern boundary should leave the Rocky 

 mountains at the head waters of the main Arkansas river near the present 

 site of Leadville. Commissioner (ireeuwood, however, who visited them in 

 1860, carried the southern limit of their couutry to the head waters of the 

 I'urgatory or Las Animas branch of the Arkansas, and the tract reserved by 

 them in the treaty of Feb. 18, 1861, includes a part of this latter country. 

 The Comanche also possessed an indefinite claim to portions of this region. 

 See treaty of Feb. IS, 1861, for the cession.
