The relations of these Indians with the United States were regulated by a treaty concluded at Hopewell, 1786, with Pio mico and other Chicasa chiefs. Their territory was then fixed at the Ohio river on the north side, and by a boundary line passing through Northern Mississippi on the south side. They began to emigrate to the west of Arkansas river early in this century, and in 1822 the population remaining in their old seats amounted to 3625. Treaties for the removal of the remainder were concluded at Pontotoc creek, October 20th, 1832, and at Washington, May 24th, 1834.
