+Okanagan+ (Salishan stock).—_Synonyms_: Oakinacken, Okinakane, Okiwahkine. They occupy the whole basin of Okanagan river in Washington, extending north into British Columbia, and including Similkameen river. The Okanagan were an important tribe or confederacy divided into a number of bands, some of which have also at times been considered as belonging to the Spokan, while others are commonly recognized as distinct tribes. Ross gives them “twelve tribes,” as follows: Skamoynumach, Kewaughtchenunaugh, Pisscow (Piskwaus), Incomecane′took, Tsillane (Chelan), Intie′took (Entiatook), Battlelemuleemauch or Meatwho (Mitaui), Inspellum (Nespelim), Sinpohellechach (Sanpoil), Sinwhoyelppetook (Colville), Samilkanuigh (Similkameen), and Oakinacken (Okanagan). They are now included within the Colville agency, and are Catholics. They were estimated at 340 in 1870 and reported as numbering 405 in 1892. +Mitaui+ (Salishan stock).—_Synonyms_: Battlelemuleemauch, Meatwho, Meshons, Meteowwee (Lewis and Clark), Methows, Mithouies. They formerly lived on the west side of the Columbia, including the basins of the Methow, Lake Chelan, and Entiatook river. Lewis and Clark met some of them in 1805 below the mouth of the Wallawalla. They are closely connected with the Piskwaus and Isle de Pierres. They now reside in Nespelim valley on Colville reservation, confederated with the Isle de Pierres under Chief Moses. The two tribes were reported at 390 in 1892. A few others live in the neighborhood of Kittitas near the Yakima tribe. See _Piskwaus_. +Isle de Pierre+ (Salishan stock).—_Synonyms_: Columbias, Linkinse, Sinkiuse. They originally occupied the country in Washington from the Columbia eastward to the Grande Coulée, extending from about the mouth of the Grande Coulée down nearly to Crab creek. Isle de Pierre is the French name of Rock island in the Columbia at the mouth of the Wenatchee. For a long time, under their noted chief Moses, they refused to recognize the authority of the government or to go on a reservation. Now, however, they are settled in Nespelim valley, on Colville reservation. They were reported to number 390 in 1892 and are described as “true, genuine Indians in every sense of the word.” Their chief, Moses, the enemy and rival of Smohalla, was thus described in 1870: “Moses, the head chief, has been a great warrior. He was foremost in the fights of 1858 with Colonels Steptoe and Wright, and was severely wounded a number of times, but not dying, the Indians believe he has a charmed life. He is medium sized, about 45 years old, noble looking, straight as an arrow, and never breaks his word. He has more influence than any other chief east of the Cascade mountains in the territory. He comes nearer being such a chief as we read of than any I have ever met. He is kindly disposed toward the whites and invites them to come and settle in his country.” (_Winans._) Linguistically they are probably nearest related to the Piskwaus.
