In pursuance of the advice and consent of the Senate as expressed in their resolution of the 10th February, 1830, the treaty of commerce and navigation between the United States and Austria concluded in this city on the 27th of August, 1829, was duly ratified by this Government on the 11th day of the same month of February; but the treaty itself containing a stipulation that the ratifications of the two parties to it should be exchanged within twelve months from the date of its signature, and that of the Austrian Government not having been received here till after the expiration of the time limited, I have not thought myself at liberty under these circumstances, without the additional advice and consent of the Senate, to authorize that ceremony on the part of this Government. Information having been received at the Department of State from the Austrian representative in the United States that he is prepared to proceed to the exchange of the ratifications of his Government for that of this, the question is therefore submitted to the Senate for their advice and consent upon the occasion. ANDREW JACKSON. _February 3, 1831_. _To the Senate of the United States_: I respectfully submit to the Senate, in answer to their legislative resolution of the 20th ultimo, in relation to the sales of land at the Crawfordsville land office in November last, reports from the Secretary of the Treasury and the Commissioner of the General Land Office. Concurring with the Secretary of the Treasury in the views he has taken of the treaties and act of Congress touching the subject, I can not discover that the President is invested with any power under the Constitution or laws to withhold a patent from a purchaser who has given a fair and valuable consideration for land, and thereby acquired a vested right to the same; nor do I perceive that the sole legislative resolution of the Senate can confer such a power, or suspend the right of the citizens to enter the lands that have been offered for sale in said district and remain unsold, so long as the law authorizing the same remains unrepealed. I beg leave, therefore, to present the subject to the reconsideration of the Senate. ANDREW JACKSON. Washington, _February 3, 1831_. _To the House of Representatives_: I transmit to the House of Representatives a report from the Treasury Department, in compliance with the resolution of the House of Representatives of the 3d ultimo, calling for the correspondence in relation to locating a cession of lands made or intended to be made by the Pottawattamie tribe of Indians for the benefit of the State of Indiana, etc. ANDREW JACKSON. _To the House of Representatives of the United States_:
