Article 4
It being understood that the present division-line between the Ioways and the Sacs and Foxes of Missouri, as run by Isaac McCoy, will, when the surveys are made, run diagonally through many of the sections, cutting them into fractions; it is agreed that the sections thus cut by said line, commencing at the junction of the Wolf with the Missouri River, shall be deemed and taken as part of the land herein before ceded and directed to be sold for the benefit of the Ioways, until the quantity thus taken, including the before-recited reservation, and all the full sections north of said line, shall amount to two hundred sections of land. And should the Sacs and Foxes of Missouri consent to a change of their residence and be so located by the United States as to occupy any portion of the land herein ceded and directed to be sold for the benefit of the Ioways, west of the tract herein reserved, the Ioways hereby agree to the same, and consent to such an arrangement, upon the condition that a quantity of land equal to that which may be thus occupied by the Sacs and Foxes, and of as good quality, shall be set apart for them out of the country now occupied by the last-named tribe, contiguous to said division-line, and sold for their benefit as hereinbefore provided.
Article 5
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.
