I communicate herewith, in compliance with the request contained in the resolution of the Senate of the 19th instant, a report of the Secretary of the Treasury, with the accompanying statement, prepared by the Register of the Treasury, which exhibits the annual amount appropriated on account of the Coast Survey from the commencement of said Survey.

JAMES K. POLK.

WASHINGTON, January 2, 1849.

To the House of Representatives of the United States:

In answer to the resolution of the House of Representatives of the 18th of December, 1848, requesting information "under what law or provision of the Constitution, or by what other authority," the Secretary of the Treasury, with the "sanction and approval" of the President, established "a tariff of duties in the ports of the Mexican Republic during the war with Mexico," and "by what legal, constitutional, or other authority" the "revenue thus derived" was appropriated to "the support of the Army in Mexico," I refer the House to my annual message of the 7th of December, 1847, to my message to the Senate of the 10th of February, 1848, responding to a call of that body, a copy of which is herewith communicated, and to my message to the House of Representatives of the 24th of July, 1848, responding to a call of that House. The resolution assumes that the Secretary of the Treasury "established a tariff of duties in the ports of the Mexican Republic." The contributions collected in this mode were not established by the Secretary of the Treasury, but by a military order issued by the President through the War and Navy Departments. For his information the President directed the Secretary of the Treasury to prepare and report to him a scale of duties. That report was made, and the President's military order of the 31st of March, 1847, was based upon it. The documents communicated to Congress with my annual message of December, 1847, show the true character of that order.

The authority under which military contributions were exacted and collected from the enemy and applied to the support of our Army during the war with Mexico was stated in the several messages referred to. In the first of these messages I informed Congress that—

On the 31st of March last I caused an order to be issued to our military and naval commanders to levy and collect a military contribution upon all vessels and merchandise which might enter any of the ports of Mexico in our military occupation, and to apply such contributions toward defraying the expenses of the war. By virtue of the right of conquest and the laws of war, the conqueror, consulting his own safety or convenience, may either exclude foreign commerce altogether from all such ports or permit it upon such terms and conditions as he may prescribe. Before the principal ports of Mexico were blockaded by our Navy the revenue derived from import duties under the laws of Mexico was paid into the Mexican treasury. After these ports had fallen into our military possession the blockade was raised and commerce with them permitted upon prescribed terms and conditions. They were opened to the trade of all nations upon the payment of duties more moderate in their amount than those which had been previously levied by Mexico, and the revenue, which was formerly paid into the Mexican treasury, was directed to be collected by our military and naval officers and applied to the use of our Army and Navy. Care was taken that the officers, soldiers, and sailors of our Army and Navy should be exempted from the operations of the order, and, as the merchandise imported upon which the order operated must be consumed by Mexican citizens, the contributions exacted were in effect the seizure of the public revenues of Mexico and the application of them to our own use. In directing this measure the object was to compel the enemy to contribute as far as practicable toward the expenses of the war.

It was also stated in that message that—

Measures have recently been adopted by which the internal as well as the external revenues of Mexico in all places in our military occupation will be seized and appropriated to the use of our Army and Navy.

The policy of levying upon the enemy contributions in every form consistently with the laws of nations, which it may be practicable for our military commanders to adopt, should, in my judgment, be rigidly enforced, and orders to this effect have accordingly been given. By such a policy, at the same time that our own Treasury will be relieved from a heavy drain, the Mexican people will be made to feel the burdens of the war, and, consulting their own interests, may be induced the more readily to requite their rulers to accede to a just peace.
