There was reason to fear in the course of the last summer that the harmony of our relations might be disturbed by the acts of certain claimants, under Mexican grants, of territory which had hitherto been under our jurisdiction. The cooperation of the representative of Mexico near this Government was asked on the occasion and was readily afforded. Instructions and advice have been given to the governor of Arkansas and the officers in command in the adjoining Mexican State by which it is hoped the quiet of that frontier will be preserved until a final settlement of the dividing line shall have removed all ground of controversy. The exchange of ratifications of the treaty concluded last year with Austria has not yet taken place. The delay has been occasioned by the nonarrival of the ratification of that Government within the time prescribed by the treaty. Renewed authority has been asked for by the representative of Austria, and in the meantime the rapidly increasing trade and navigation between the two countries have been placed upon the most liberal footing of our navigation acts. Several alleged depredations have been recently committed on our commerce by the national vessels of Portugal. They have been made the subject of immediate remonstrance and reclamation. I am not yet possessed of sufficient information to express a definitive opinion of their character, but expect soon to receive it. No proper means shall be omitted to obtain for our citizens all the redress to which they may appear to be entitled. Almost at the moment of the adjournment of your last session two bills--the one entitled "An act for making appropriations for building light-houses, light-boats, beacons, and monuments, placing buoys, and for improving harbors and directing surveys," and the other "An act to authorize a subscription for stock in the Louisville and Portland Canal Company"--were submitted for my approval. It was not possible within the time allowed me before the close of the session to give to these bills the consideration which was due to their character and importance, and I was compelled to retain them for that purpose. I now avail myself of this early opportunity to return them to the Houses in which they respectively originated with the reasons which, after mature deliberation, compel me to withhold my approval. The practice of defraying out of the Treasury of the United States the expenses incurred by the establishment and support of light-houses, beacons, buoys, and public piers within the bays, inlets, harbors, and ports of the United States, to render the navigation thereof safe and easy, is coeval with the adoption of the Constitution, and has been continued without interruption or dispute.
