In addition to the provision contained in the treaty of 1866 concerning the location of _civilized_ Indians east of 96°, the sixteenth article of that treaty made further provision enabling the United States to locate _friendly_ tribes on Cherokee lands west of that meridian. The conditions of this concession were that any tracts selected for such location should be in compact form and in quantity not exceeding 160 acres for each member of the tribe so located, and that the boundaries of the tracts should be surveyed and marked and should be conveyed in fee simple to the tribes respectively located thereon. It was further stipulated that the price to be paid for the lands so set apart should be such as might be agreed upon between the Cherokees and the immigrant tribes, subject to the approval of the President of the United States, who, in case of a disagreement between the parties in interest, was authorized to fix the value. _Osages._--The treaty of September 29, 1865,[634] with the Osages, having in view the possibility of some early arrangement whereby the Kansas tribes might be removed to Indian Territory, made provision that in case such a removal of the Osages should take place their remaining lands in Kansas should be disposed of and 50 per cent. of the proceeds might be applied to the purchase of their new home. Nothing was done in the line of carrying out this idea until the spring of 1868, when, in reply[635] to a communication from the Commissioner of Indian Affairs on the subject, the Cherokee delegation asserted the willingness of their nation to dispose of a tract for the future home of the Osages not exceeding 600,000 acres in extent and lying west of 96°, provided a reasonable price could be agreed upon for the same. A few weeks later[636] a treaty was concluded between the United States and the Osages, which made provision for setting apart a tract for their occupation in the district of country in question, but the treaty failed of ratification. The necessity for their removal from Kansas, however, increased in correspondence with the demands of advancing settlements, and Congress, by an act approved July 15, 1870,[637] provided that, whenever the Osages should give their assent, a tract should be set apart for their permanent occupancy in the Indian Territory equal in extent to 160 acres for each member of the tribe who should remove there. For this tract they were to pay a price not exceeding that paid by the United States, the cost to be defrayed out of the proceeds arising from the sale of their Kansas lands. The assent of the Osages to the provisions of this act was promptly secured through the medium of a commission consisting of J. V. Farwell, J. D. Lang, and Vincent Colyer, of the President's Board of Indian Commissioners. A tract was selected in the Cherokee country immediately west of 96°, as was supposed, and the Osages were removed to it. Their condition was for a time, however, most unsatisfactory.
