The Otoes and Missouris are tribes of the Siouan family. They were placed on a reservation in the country about the Nemaha River, in what became Kansas and Nebraska. By a treaty made September 21, 1833, they ceded their country south of the Little Nemaha. The remainder of their lands were ceded to the United States by a treaty made March 15, 1854, and they were assigned a diminished reservation on the waters of the Big Blue River. This tract was twenty-five miles long—east and west—by ten miles wide. It was surveyed to please the Indians from some point called by them the “Islands.” The south boundary fell two miles below or south of the north line of Kansas. They lived there until the white people crowded them out, moving to the Indian Territory in 1881. It required twenty years to quiet the title to this reservation. As usual, the Indians received only a small part of the value of the land.
