Had the vessels and cargoes belonging to citizens of the United States been admitted without the payment of any duty, while a duty was levied on foreign vessels and cargoes, the object of the order would have been defeated. The whole commerce would have been conducted in American vessels, no contributions could have been collected, and the enemy would have been furnished with goods without the exaction from him of any contribution whatever, and would have been thus benefited by our military occupation, instead of being made to feel the evils of the war. In order to levy these contributions and to make them available for the support of the Army, it became, therefore, absolutely necessary that they should be collected upon imports into Mexican ports, whether in vessels belonging to citizens of the United States or to foreigners. It was deemed proper to extend the privilege to vessels and their cargoes belonging to neutral nations. It has been my policy since the commencement of the war with Mexico to act justly and liberally toward all neutral nations, and to afford to them no just cause of complaint; and we have seen the good consequences of this policy by the general satisfaction which it has given. In answer to the inquiry contained in the resolution as to the rates of duties imposed, I refer you to the documents which accompanied my annual message of the 7th of December last, which contain the information. From the accompanying reports of the Secretary of War and the Secretary of the Navy it will be seen that the contributions have been collected on all vessels and cargoes, whether American or foreign; but the returns to the Departments do not show with exactness the amounts collected on American as distinguishable from foreign vessels and merchandise. JAMES K. POLK. WASHINGTON, _February 10, 1848_. _To the House of Representatives of the United States_: In answer to the resolution of the House of Representatives of the 7th instant, I transmit herewith a report from the Secretary of State. No communication has been received from Mexico "containing propositions from the Mexican authorities or commissioners for a treaty of peace," except the "counter projet" presented by the Mexican commissioners to the commissioners of the United States on the 6th of September last, a copy of which, with the documents accompanying it, I communicated to the Senate of the United States on the 2d instant. A copy of my communication to the Senate embracing this "projet" is herewith communicated. JAMES K. POLK. WASHINGTON, _February 14, 1848_. _To the Senate of the United States_:
