The preamble recites the desire of the United States to secure to the Cherokees, both east and west of the Mississippi, a permanent home, "that shall never in all future time be embarrassed by having extended around it the lines or placed over it the jurisdiction of a Territory or State, nor be pressed upon by the extension in any way of any of the limits of any existing Territory or State." It also assumes that their actual surroundings, both east and west of such river, were unadapted to the accomplishment of such a purpose, and therefore the following articles of agreement were made: 1. The western boundary of Arkansas shall be * * * viz: A line shall be run commencing on Red River at the point where the Eastern Choctaw line strikes said river, and run due north with said line to the river Arkansas; thence in a direct line to the southwest corner of Missouri. 2. The United States agree to possess the Cherokees, and to guarantee it to them forever, * * * of seven million of acres of land, to be bounded as follows, viz: Commencing at that point on Arkansas River where the eastern Choctaw boundary lines strikes said river, and running thence with the western line of Arkansas, as defined in the foregoing article, to the southwest corner of Missouri, and thence with the western boundary line of Missouri till it crosses the waters of Neasho, generally called Grand River; thence due west to a point from which a due-south course will strike the present northwest corner of Arkansas Territory; thence continuing due south on and with the present western boundary line of the Territory to the main branch of Arkansas River; thence down said river to its junction, with the Canadian River, and thence up and between the said rivers Arkansas and Canadian to a point at which a line running north and south from river to river will give the aforesaid seven million of acres. In addition to the seven millions of acres thus provided for and bounded, the United States guarantee to the Cherokee Nation a perpetual outlet west, and a free and unmolested use of all the country lying west of the western boundary of the above described limits and as far west as the sovereignty of the United States and their right of soil extend. 3. The United States agree to survey the lines of the above cession 4. The United States agree to appraise and pay the value of all Cherokee improvements abandoned by the latter in their removal; also to sell the property and improvements connected with the agency, for the erection of a grist and saw mill in their new home.
