By treaties made in 1826 and 1827 the Creeks had ceded all their remaining lands in Georgia and agreed to remove to Indian Territory. Some of these emigrants had settled along the northern bank of the Arkansas and on Verdigris river, on lands later found to be within the limits of the territory assigned to the western Cherokee by the treaty of 1828. This led to jealousies and collisions between the two tribes, and in order to settle the difficulty the United States convened a joint council of Creeks and Cherokee at Fort Gibson, with the result that separate treaties were concluded with each on February 14, 1833, defining their respective bounds to the satisfaction of all concerned. By this arrangement the upper Verdigris was confirmed to the Cherokee, and the Creeks who had settled along that portion of the stream agreed to remove to Creek territory immediately adjoining on the south. [354] By the treaty made on this occasion with the Cherokee the boundaries of the tract of seven million acres granted by the treaty of 1828 are defined so as to correspond with the present boundaries of the Cherokee country in Indian territory, together with a strip two miles wide along the northern border, which was afterward annexed to the state of Kansas by the treaty of 1866. A tract in the northeastern corner, between Neosho or Grand river and the Missouri line, was set apart for the use of the Seneca and several other remnants of tribes removed from their original territories. The western outlet established by the treaty of 1828 was reestablished as a western extension from the seven-million-acre tract thus bounded, being what was afterward known as the Cherokee strip or outlet plus the two-mile strip extending westward along the south line of Kansas. After describing the boundaries of the main residence tract, the first article continues: In addition to the seven millions of acres of land thus provided for and bounded the United States further 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 said seven millions of acres, as far west as the sovereignty of the United States and their right of soil extend--provided, however, that if the saline or salt plain on the great western prairie shall fall within said limits prescribed for said outlet the right is reserved to the United States to permit other tribes of red men to get salt on said plain in common with the Cherokees--and letters patent shall be issued by the United States as soon as practicable for the lands hereby guaranteed. The third article cancels, at the particular request of the Cherokee, that article of the treaty of 1828 by which the government was to give to the Cherokee a set of laws and a surveyor to survey lands for individuals, when so desired by the Cherokee.
