The nationality of the great tribes, or more properly speaking, their political importance, was still further recognized by clauses guaranteeing territorial and political integrity,[263] representation by delegates[264] in the Confederate Congress, and the prospect[265] of ultimate statehood. The guarantee of territorial integrity was, of a certainty, not new. It had been inserted into various removal treaties as a safeguard against a repetition of the injustice that had been meted out to the Indians by the Southern States in Jackson's day. It comprised, in effect, a solemn promise that no state or territorial lines should ever again circumscribe the particular domain of the Indian nation securing the guarantee; and that state or territorial laws, as the case might be, should have no operation within the Indian country. The idea of congressional representation[266] was also not new, but where it had previously been but a promise or a mere contingency, it was now an assured fact, a thing definitely provided for. Ultimate statehood had, however, attached to it the old time elements of uncertainty, which is not at all surprising, considering that Walker, in his instructions[267] to Hubbard, had positively spoken against it. All the treaties, without distinction of class, recognized the land rights of the Indians and their existing territorial limits, but with the usual restriction upon alienation to foreign powers. A sale or cession to a foreign state, without the consent of the Confederate States, was to result in forfeiture and reversion to the Confederate States. By the Choctaw and Chickasaw Treaty, the arrangement,[268] already satisfactorily reached, for a Chickasaw country distinct from a Choctaw was continued, the Indians of both tribes being given the privilege of having their particular land surveyed and sectionized whenever they might so please, provided it be done by regular legislative process.[269] The same treaty transferred[270] the lease of the Wichita Reserve from the United to the Confederate States and limited it to ninety-nine years. Practically the same bands of Indians were to be accommodated in this Leased District as before; namely, those whose permanent ranges were south of the Canadian or between it and the Arkansas. The New Mexican Indians were still to be absolutely excluded. The Choctaw and Chickasaw Indians reserved the right to pass upon the accommodation of any other Indians than those specifically mentioned in the treaty. The individual bands, so accommodated in the Leased District, were to be settled upon reserves and to hold the same in fee. Finally, the treaty placed,[271] for the time being, the Wichitas and their fellow reservees exclusively under the control of the Confederate States with a limited jurisdiction resting in the Choctaw Nation and a full right of settlement in Choctaws and Chickasaws.
