These demands for negroes increased in number; and the whites became more and more rapacious, and the Indians more and more indignant, until hostilities appeared inevitable. The Agent, from long association with the Indians and his knowledge of facts, naturally sympathised with them. He assembled a number of the chiefs at the Agency, and suggested to them the absolute necessity of submitting to the white people; and for the purpose of avoiding further difficulties, advised them to emigrate west of the Mississippi, or, rather, to send a delegation to examine the country; and, as an inducement, offered to accompany their chiefs and warriors on such a tour. To this proposition a few of them consented, and the Agent notified the Department of the fact.[65] It was easy to see that, under the existing state of affairs, hostilities could not long be avoided. Up to the period of which we are speaking, the action of our Government had been dictated by those who sought to uphold and encourage Slavery; nor could it be expected that this long-established policy would be suddenly changed, unless such change were peremptorily demanded by the people. There was apparently but one course to be pursued under this policy--that was the removal of the Indians from Florida. This plan had been recommended by General Jackson ten years previously, and he now being President, had an opportunity of carrying out his proposed policy. To effect this purpose, it would be necessary to negotiate a treaty by which the Indians should consent to abandon Florida and remove west of the Mississippi. It had long been the policy of those who administered the Government, to select Southern men to act in all offices in which the institution of slavery was likely to be called in question. From the time General Washington sent Colonel Willett to ascertain facts in regard to the controversy between the State of Georgia and the Creek Indians, in 1789, to the period of which we are now speaking, no Northern man was appointed to any office which required his personal attention to the situation of the Exiles.[66] [Sidenote: 1832.] In accordance with this practice, General Cass, acting as Secretary of War, appointed Colonel James Gadsden, of South Carolina, to negotiate the treaty of Payne's Landing. By the preamble of this treaty, the Seminoles stipulated that eight of their principal chiefs should visit the Western country, "_accompanied by their faithful interpreter, Abraham_," (an Exile, and a man of great repute among both Exiles and Indians,) and should they be satisfied with the character of the country, and of the favorable disposition of the Creeks to reunite with the Seminoles as one people, they would, in such case, agree to the stipulations subsequently contained in said treaty. The first article merely makes an exchange, by the Seminoles, of lands in Florida for an equal extent of territory, west of the Mississippi, adjoining the Creek Nation.
