By the fifteenth article of the treaty of 1866 provision was made that, upon certain conditions, the United States should have the right to settle civilized Indians upon any unoccupied Cherokee territory east of 96° west longitude. The material conditions limiting this right were that terms of settlement should be agreed upon between the Cherokees and the Indians so desiring to settle, subject to the approval of the President of the United States; also that, in case the immigrants desired to abandon their tribal relations and become citizens of the Cherokee Nation, they should first pay into the Cherokee national fund a sum of money which should sustain the same proportion to that fund that the number of immigrant Indians should sustain to the whole Cherokee population. If, on the other hand, the immigrants should decide to preserve their tribal relations, laws, customs, and usages not inconsistent with the constitution and laws of the Cherokee Nation, a tract of land was to be set apart for them by metes and bounds which should contain, if they so desired, a quantity equal to 160 acres for each soul. For this land they were to pay into the Cherokee national fund a sum to be agreed upon between themselves and the Cherokees, subject to the approval of the President, and also a sum bearing a ratio to the Cherokee national fund not greater than their numbers bore to the Cherokees. It was also stipulated that, if the Cherokees should refuse their assent to the location of any civilized tribe (in a tribal capacity) east of 96°, the President of the United States might, after a full hearing of the case, overrule their objections and permit the settlement to be made. The Delawares were the first tribe to avail themselves of the benefits of the foregoing treaty provisions. Terms of agreement were entered into between them and the Cherokees, which were ratified by the President on the 11th of April, 1867. Under the conditions of this instrument the Delawares selected a tract of land equal to 160 acres for each member of their tribe who should remove to the Cherokee country. For this tract they agreed to and did pay one dollar per acre. They also paid their required proportional sum into the Cherokee national fund. The number of Delawares who elected to remove under this agreement was 985. The sums they were required to pay were: for land, $157,600; and as their proportion of the national fund, $121,834.65, the latter amount having been calculated on the basis of an existing Cherokee national fund of $1,678,000 and a population of 13,566.[626]
