In 1842, after a treaty between the United States and the Wyandots, the Wyandot moved to the junction of the Kansas and Missouri Rivers (on land that was shared with the Delaware until 1843). In an unusual provision, 35 Wyandot were given "floats" in the 1842 treaty – ownership of sections of land that could be located anywhere west of the Missouri River. In 1847, the Pottawatomi were moved again, to an area containing 576,000 acres (2,330 km2), being the eastern part of the lands ceded to the United States by the Kansa tribe in 1846. This tract comprised a part of the present counties of Pottawatomie, Wabaunsee, Jackson and Shawnee.
