Note 290 — THE MISSOURI RIVER JOURNALS

This is the largest river which enters the Missouri thus far above Big Sioux River, coming from the north through South Dakota. The origin of the name, as given by Audubon, is known to few persons. Jacques is French for "James," and the stream has oftener been known as James River. Another of its names was Yankton River, derived from that of a tribe of the Sioux. But it is now usually called Dakota River, and will be found by this name on most modern maps.—E. C.
