Note 105 — LETTER I

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.
