From this showing it was made evident to the delegation, and no opportunity was lost to impress the fact strongly upon them, that if they insisted upon refusing to arrange for an exchange of lands, instead of being entitled to a large additional tract beyond their provisional western boundary, they would, in fact, be entitled to several hundred thousand acres less than had already been placed in their possession. In addition to this it was more than doubtful, from the temper of the President and Congress, whether their long anticipated "western outlet" would ever crystallize into anything more tangible than a promise. With these facts staring them in the face, with the alluring offers held out to them of double the quantity of land possessed by them in Arkansas in exchange, with liberal promises of assistance in their proposed new homes, and with the persistent importunities of their agent and other United States officials, they yielded, and the treaty of May 6, 1828,[330] an abstract of which has been already given, was the result. It was promptly ratified and proclaimed on the 28th of the same month. So nervous were the members of the delegation, after the treaty had been concluded and signed, as to the reception that would greet them on their return home, that the Secretary of War felt the necessity of giving them a letter of explanation to their people. In this letter the Cherokees were advised of the integrity, good conduct, and earnest zeal for the welfare of their nation that had invariably characterized the actions of their delegation at Washington. The nation was assured that their representatives had done the best thing possible for them to do in the late treaty.[331] Notwithstanding this testimonial, the delegation met with an angry reception on their return home. Their lives and property were unsafe; the national council pronounced them guilty of fraud and deception, declared the treaty to be null and void, as having been made without any authority, and expressed an earnest desire to send a delegation to Washington clothed with power to arrange all differences.[332] In the mean time Agent Duval had been advised[333] of the ratification of the treaty, and Messrs. R. Ellis and A. Finney had been appointed, in conjunction with him, as commissioners to value all improvements and property abandoned by the Cherokees, and to sell the agency property as a means of raising funds for the erection of mills in their new country. _Survey of new boundaries._--The eastern line of this new Cherokee country, dividing it from Arkansas, was surveyed in 1829,[334] but it was not until April 13, 1831, that instructions were given to Isaac McCoy to survey the remaining boundaries.
