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

Whereas such acts and practices are contrary to the law of the land and the provisions of the act of Congress approved the 3d day of March, A.D. 1807, and are offenses against the peace and public tranquillity of the said Territory and the inhabitants thereof: 

Now, therefore, be it known that I, Andrew Jackson, President of the United States, by virtue of the power and authority vested in me in and by the said act of Congress, do issue this my proclamation, commanding and strictly enjoining all persons who have unlawfully entered upon, taken possession of, or made any settlement on the public lands in the said counties of Lafayette, Sevier, or Miller, or who may be in the unlawful occupation or possession of the same, or any part thereof, forthwith to depart and remove therefrom; and I do hereby command and require the marshal of the said Territory of Arkansas, or other officer or officers acting as such marshal, from and after the 15th day of April next to remove or cause to be removed all persons who may then unlawfully be upon, in possession of, or who may unlawfully occupy
