The United States agree, whenever the President may think it necessary and proper, to convene such of the tribes, either separately or together, as are interested in the lines left unsettled herein, and to recommend to them an amicable and final adjustment of their respective claims, so that the work, now happily begun, may be consummated. It is agreed, however, that a Council shall be held with the Yancton band of the Sioux, during the year 1826, to explain to them the stipulations of this treaty, and to procure their assent thereto, should they be disposed to give it, and also with the Ottoes, to settle and adjust their title to any of the country claimed by the Sacs, Foxes, and Ioways. * * * ARTICLE XIII It is understood by all the tribes, parties hereto, that no tribe shall hunt within the acknowledged limits of any other without their assent, but it being the sole object of this arrangement to perpetuate a peace among them, and amicable relations being now restored, the Chiefs of all the tribes have expressed a determination, cheerfully to allow a reciprocal right of hunting on the lands of one another, permission being first asked and obtained, as before provided for. ARTICLE XIV Should any causes of difficulty hereafter unhappily arise between any of the tribes, parties hereunto, it is agreed that the other tribes shall interpose their good offices to remove such difficulties; and also that the government of the United States may take such measures as they may deem proper, to effect the same object. ARTICLE XV This treaty shall be obligatory on the tribes, parties hereto, from and after the date hereof, and on the United States, from and after its ratification by the government thereof.
