Ballard reported that on August 26, 1867, a treaty was signed by Tygee, Peter, To-so-copy-natey, Pah Vissigin, McKay, and Jim, in which the Bannock agreed to settle on Fort Hall (Ballard, 1869, p. 658); the Bannock and also the Bruneau and Boise Shoshone were removed from the Boise Valley on December 2, 1868, and brought to Fort Hall (C. F. Powell, 1870, p. 728). They were joined there by 500 Bannock under Tygee, who had just returned from a joint buffalo hunt with the Eastern Shoshone in Wind River Valley (p. 729). Indian Agent Danilson of Fort Hall wrote that in 1869 there were 600 Bannock, 200 Boise Shoshone, 100 Bruneau Shoshone, and 200 Western Shoshone on the reservation (Danilson, 1870, p. 729). The beginning of the reservation period marks the effective end of the independent occupancy of the Idaho area by the Shoshone and Bannock. The rest of this section deals with ethnographic data. In regard to extent of Shoshone settlement, Omer Stewart has reported that eastern Oregon, about the mouths of the Malheur and Owyhee rivers, and southwest Idaho as far east as a line well past Boise, were the territory of a Northern Paiute band called the Koa'agaitoka (Stewart, 1939, p. 133). Blythe places a Northern Paiute band called "Yapa Eaters" in the Boise River Valley (Blythe, 1938, p. 396) and mentions data given by one informant to the effect that a mixed band of Paiute and Shoshone called "People Eaters" lived to the north of the Yapa Eaters (p. 404). Neither historical research nor ethnographic investigation among the Shoshone confirms the existence of such bands in the area described. On the contrary, Steward writes (1938, p. 172): Shoshone seem to have extended westward about to the Snake River which forms the boundary between Idaho and Oregon. They also occupied the Boise River Valley and probably to some extent the valleys of the Payette and Weiser Rivers. They probably never penetrated Oregon beyond the Blue Mountains. But the area nearer the Snake River was not occupied exclusively by Shoshone, for Steward continues (ibid.): This population was neither well defined politically nor territorially. It was scattered in small independent villages of varying prosperity and tribal composition. Along the lower Snake, Boise, and Payette Rivers Shoshone were intermixed with Northern Paiute who extended westward through the greater portion of southern and eastern Oregon. Slightly to the north they were probably mixed somewhat with their Nez Perce neighbors. Our own field work, as presented below, tends to confirm Steward's data on most points and is in accord with historical information.
