volume xxii, p. 315, note 277. For a description of the Little

Missouri River, more frequently known as Teton or Bad, see our volume xxiii, p. 94, note 81.--ED.

[102] The reference is to the various divisions of the Dakota or Sioux; but the classification is unsatisfactory. For recent classification, see J. W. Powell, U. S. Bureau of Ethnology _Report_, 1885-86, pp. 111-113; also Maximilian's _Travels_, in our volume xxii, p. 326, note 287. By the "Jantonnais" and "Jantons," De Smet intends the modern Yanktonai and Yankton.--ED.

[103] Vermillion Post, established for trading with the lower Sioux tribes, was located on the east bank of the Missouri, ten miles below the mouth of the Vermillion. The shifting of the stream has since 1881 rendered difficult the locating of the old post, which was described by Audubon, who passed there in 1843; see M. R. Audubon, _Audubon and his Journals_ (New York, 1897), i, pp. 493, 494. Also consult _South Dakota Historical Collections_, i, pp. 376, 377. Dickson's post, also called Fort Vermillion, was some miles above the river of that name. See our volume xxiv, p. 97, note 73. It is uncertain which post is intended.--ED.

[104] By the treaty made at Chicago in September, 1833, the Potawatomi, Ottawa, and Chippewa ceded to the United States government about five million acres of land, whereupon the Potawatomi were assigned to a reservation between the western borders of the state of Missouri and the Missouri River, in what was later known as the Platte purchase. This tract was incorporated with Missouri in 1836, and the Indian tribe was transferred to a reservation in southwestern Iowa, with Council Bluffs as their chief village. Here in 1838 Father Verreydt, with Father de Smet and two lay brothers, laid the foundation of a mission dedicated to the "Blessed Virgin and St. Joseph," where De Smet served until his departure for the Flathead country (1840). Father Christian Hoecken succeeded him. By the treaty of 1846 the Potawatomi were transferred from Iowa to Kansas, where another Catholic mission was begun among them, frequently visited by De Smet in his later life.--ED.

[105] In 1839 Father de Smet undertook a journey from St. Joseph's mission, at Council Bluffs, into the Sioux territory for the purpose of effecting a treaty between these tribes and the Potawatomi. He ascended the Missouri in the steamer of the American Fur Company, on which J. N. Nicollet, the famous geographer, was likewise a passenger. See Chittenden and Richardson, _De Smet_, i, pp. 179-192.--ED.
