As the receipts from the sales of the lands cannot now be determined, it is agreed that the whole subject shall be referred to the President of the United States, who may, from time to time, prescribe how much of the proceeds thereof shall be paid out to the Ioway people, and the time and mode of such payment, and also how much shall be invested in safe and profitable stocks, the principal of which to remain unimpaired, and the interest to be applied annually for the civilization, education, and religious culture of the Ioways and such other objects of a beneficial character as may be proper and essential to their well-being and prosperity: provided, that if necessary, Congress may, from time to time, by law, make such regulations in regard to the funds arising from the sale of said lands, and the application thereof for the benefit of the Ioways, as may in the wisdom of that body seem just and expedient. ARTICLE 6 The President may cause the country the Ioways have reserved for their future home, to be surveyed, at their expense, and in the same way as the public lands are surveyed, and assign to each person or family such portion thereof as their industry and ability to manage business affairs may, in his opinion, render judicious and proper; and Congress may hereafter provide for the issuing to such persons, patents for the same, with guards and restrictions for their protection in the possession and enjoyment thereof. ARTICLE 7 Appreciating the importance and the benefit derived from the mission established among them by the board of foreign missions of the Presbyterian Church, the Ioways hereby grant unto the said board a tract of three hundred and twenty acres of land, to be so located as to include the improvements at the mission, and also a tract of one hundred and sixty acres of timbered land, to be selected by some agent of the board from the legal subdivisions of the surveyed land; and the President shall issue a patent or patents for the same, to such person or persons as said board may direct. They further grant to John B. Roy, their interpreter, a tract of three hundred and twenty acres of land, to be selected by him in “Wolf’s Grove,” for which the President shall also issue a patent. ARTICLE 8 The debts of Indians contracted in their private dealings as individuals, whether to traders or otherwise, shall not be paid out of the general fund. ARTICLE 9
