On the 24th of June last a convention of navigation and commerce was concluded in this city between the United States and France by ministers duly authorized for the purpose. The sanction of the Executive having been given to this convention under a conviction that, taking all its stipulations into view, it rested essentially on a basis of reciprocal and equal advantage, I deemed it my duty, in compliance with the authority vested in the Executive by the second section of the act of the last session of the 6th of May, concerning navigation, to suspend by proclamation until the end of the next session of Congress the operation of the act entitled "An act to impose a new tonnage duty on French ships and vessels, and for other purposes", and to suspend likewise all other duties on French vessels or the goods imported in them which exceeded the duties on American vessels and on similar goods imported in them. I shall submit this convention forthwith to the Senate for its advice and consent as to the ratification. Since your last session the prohibition which had been imposed on the commerce between the United States and the British colonies in the West Indies and on this continent has likewise been removed. Satisfactory evidence having been adduced that the ports of those colonies had been opened to the vessels of the United States by an act of the British Parliament bearing date on the 24th of June last, on the conditions specified therein, I deemed it proper, in compliance with the provision of the first section of the act of the last session above recited, to declare, by proclamation bearing date on the 24th of August last, that the ports of the United States should thenceforward and until the end of the next session of Congress be opened to the vessels of Great Britain employed in that trade, under the limitation specified in that proclamation. A doubt was entertained whether the act of Congress applied to the British colonies on this continent as well as to those in the West Indies, but as the act of Parliament opened the intercourse equally with both, and it was the manifest intention of Congress, as well as the obvious policy of the United States, that the provisions of the act of Parliament should be met in equal extent on the part of the United States, and as also the act of Congress was supposed to vest in the President some discretion in the execution of it, I thought it advisable to give it a corresponding construction. Should the constitutional sanction of the Senate be given to the ratification of the convention with France, legislative provisions will be necessary to carry it fully into effect, as it likewise will be to continue in force, on such conditions as may be deemed just and proper, the intercourse which has been opened between the United States and the British colonies. Every light in the possession of the Executive will in due time be communicated on both subjects.
