I submit to the consideration of the Senate of the United States articles of agreement and convention concluded this day between the United States, by a commissioner duly authorized, and the Seneca tribe of Indians resident in the State of Ohio. ANDREW JACKSON. _February 28, 1831_. _February 28, 1831_. _The Speaker of the House of Representatives of the United States_: I lay before the House of Representatives a treaty recently concluded with the Choctaw tribe of Indians, that provision may be made for carrying the same into effect agreeably to the estimate heretofore presented by the Secretary of War to the Committee of Ways and Means. It is a printed copy as it passed the Senate, no amendment having been made except to strike out the preamble. I also communicate a letter from the Secretary of War on this subject. ANDREW JACKSON. _March 1, 1831_. _To the Senate of the United States_: I transmit herewith, for the use of the Senate, printed copies of the treaties which have been lately ratified between the United States and the Choctaw Indians and between the United States and the confederated tribes of the Sacs and Foxes and other tribes. ANDREW JACKSON. (The same message was sent to the House of Representatives.) WASHINGTON, _March 2, 1831_. _To the Senate and House of Representatives of the United States_: I communicate to Congress a treaty of commerce and navigation between the United States and the Emperor of Austria, concluded in this city on the 28th March, 1830, the ratifications of which were exchanged on the 10th of February last. ANDREW JACKSON. _March 2, 1831_. _To the Senate of the United States_: John H. Clack, a master commandant in the Navy of the United States, having rank as such from the 24th April, 1828, was on the sentence of a court-martial, which was approved by me, ordered to be dismissed from the service. On a reexamination of the record of the trial I am satisfied that the proceeding was illegal in substance, and therefore that the sentence was void. To restore the party to the rights of which he was deprived by the enforcement of a sentence which was in law erroneous and void, I nominate the said John H. Clack to be a master commandant in the Navy of the United States, to take rank as such from the 24th April, 1828. ANDREW JACKSON. PROCLAMATION. BY THE PRESIDENT OF THE UNITED STATES. A PROCLAMATION. Whereas information has been transmitted to the President of the United States by the governor of the Territory of Arkansas that certain persons pretending to act under the authority of the Mexican Government, and without any lawful right or power derived from that of the United States, have attempted to and do survey, for sale and settlement, a portion of the public lands in said Territory, and particularly in the counties of Lafayette, Sevier, and Miller, and have presumed to and do administer to the citizens residing in said counties the oath of allegiance to the said Mexican Government; and
