Yahuskin Indians. A Shoshonean band which prior to 1864 roved and hunted with the Walpapi about the shores of Goose, Silver, Warner, and Harney Lakes, Oregon, and temporarily in Surprise Valley and Klamath Marsh, where they gathered wokas for food. They came specially into notice in 1864, on Oct. 14 of which year they became party to the treaty of Klamath Lake by which their territory was ceded to the United States and they were placed on Klamath Reservation, established at that time. With the Walpapi and a few Paiute who had joined them, the Yahuskin were assigned lands in the southern part of the reservation, on Sprague river about Yainax, where the have since resided, although through intermarriage with other Indians on the reservation their tribal identity became lost by 1898, since which time they have been officially designated as Paiute. Gatschet, who visited them about 1884, says they were then engaged in agriculture, lived in willow lodges and log houses, and were gradually abandoning their roaming proclivities. The Yahuskin have always been officially enumerated with the Walpapi, the aggregate population varying between 1877 and 1891 from 135 to 166 persons. In 1909 they were reported at 103.
