+Kwikwû′lĭt+ or +Dog River+ (Chinookan stock).—_Synonyms_: Cascade Indians, Kigaltwalla, Upper Chinook, Wahclellah, Watlala. A small tribe formerly living at the Cascades and about Dog river, a small stream coming into the Columbia about half-way between the Cascades and The Dalles, in Wasco county, Oregon. They are identical, in part at least, with the Wahclellahs of Lewis and Clark (mentioned as a part of the “Shahala nation”), and are the “Ki-gal-twal-la band of the Wascoes” and the “Dog River band of the Wascoes” of the Wasco treaty of 1855. The “Dog River or Cascade Indians” were reported to number 80 souls in 1854. In the next year they, with other tribes, entered into the Wasco treaty, by which they agreed to remove to Warmspring reservation, where some of them now are, while the others are still about the Cascades. Their language is nearly the same as that of the Wasko. +Wasko+ (Chinookan stock).—_Synonyms_: Dalles Indians, Wascopum. A tribe formerly claiming the country about The Dalles, on the south bank of the Columbia, in Wasco county, Oregon. They, with the Tlaqluit on the opposite bank, are the easternmost extension of the Chinookan stock, and speak the same language. The name is said to be a Tenino word, meaning “grass,” or “grass people.” It has sometimes been made to include several cognate bands about The Dalles and Cascades, on both sides of the Columbia. Under the name of “The Dalles band of the Wascoes,” they entered into the Wasco treaty of 1855, and are now on Warmspring reservation in Oregon. They numbered 260 in 1892. +Waiäm+ (Shahaptian stock).—_Synonyms_: (Lower) Des Chutes, Waiäm-‛lĕma, Wayyampa, Wyam. A tribe speaking the Tenino language and formerly living about the mouth of Des Chutes river, in the present Wasco and Sherman counties, Oregon. Their chief village was on the Columbia where Celilo now is, and was called Waiäm, whence their name of Waiäm-‛lĕma or “people of Waiäm.” They joined in the Wasco treaty of 1855 under the name of “Wyam or Lower Des Chutes band of Walla-Wallas,” and are now on Warmspring reservation in Oregon. Their number is not separately reported. +Tai′-ăq+ (Shahaptian stock).—_Synonyms_: Taigh, Ta-ih, Tairtla, Tyich. A tribe speaking the Tenino language and formerly occupying the country about Tygh and White rivers, in Wasco county, Oregon. The name Tai′-ăq refers to the stream and denotes “muddy, white water.” They took part in the Wasco treaty of 1855 under the name of “Ta-ih or Upper Des Chutes band of Walla-Wallas,” and are now on Warmspring reservation, Oregon. Their number is not reported.
