has fallen into disuse.” A few years ago only a few individuals, then living on Umatilla reservation, retained their old language. In 1855 they joined in the treaty by which Umatilla reservation in Oregon was set apart, and most of those remaining are now there, while a few others are with the Nez Percés at Lapwai. Joseph, the noted Nez Percé chief, is himself the son of a Cayuse father. In 1892 the Cayuse on Umatilla reservation were reported to number 391, but it is evident that most of these are mixed-bloods of other tribes, particularly the Umatilla. The name Cayuse is from the Nez Percé language. They call themselves Wailĕtpu. They are known to the Yakima as Wi′alĕt-pûm or Wai′lĕtma, and to the Tenino as Shiwanish, or “strangers from up the river,” a name extended also to the Nez Percés. +Umatilla+ (Shahaptian stock).—_Synonym_: Utilla. A tribe formerly occupying the lower portion of the river of the same name, with the adjacent bank of the Columbia, in Oregon. They speak a distinct language of the Shahaptian stock. By the treaty of 1855 they agreed to go on Umatilla reservation in Oregon, where in 1892 they were reported to number 216. A large proportion of those now called Cayuse on the same reservation are Umatilla mixed-bloods. +Wallawalla+ (Shahaptian stock).—_Synonyms_: Oualla-Oualla, Walawaltz, Wollawollah, Wollaw-Wollah. A tribe formerly occupying the country about the lower portion of the river of the same name and along the east bank of the Columbia from Snake river down nearly to the Umatilla, in Washington and Oregon. They take their name from the river, the word being said to refer to “rushing water.” Their language is said to resemble closely that of the Nez Percés. By the treaty of 1855 they agreed to go on Umatilla reservation, Oregon, where, in 1892, they were reported to number 474. A small band of the same tribe, known to the Yakima as Walu′la-pûm, formerly lived on the west bank of the Columbia opposite the present Wallula. Their dialect is said to have been more akin to the Pä′lus language.
