A convention to this effect was concluded and signed in London on March 13th, 1824, by plenipotentiaries duly authorized by both Governments, to the ratification of which certain obstacles have arisen which are not yet entirely removed. The difference between the parties still remaining has been reduced to a point not of sufficient magnitude, as is presumed, to be permitted to defeat an object so near to the heart of both nations and so desirable to the friends of humanity throughout the world. As objections, however, to the principle recommended by the House of Representatives, or at least to the consequences inseparable from it, and which are understood to apply to the law, have been raised, which may deserve a reconsideration of the whole subject, I have thought it proper to suspend the conclusion of a new convention until the definitive sentiments of Congress may be ascertained. The documents relating to the negotiation are with that intent submitted to your consideration. Our commerce with Sweden has been placed on a footing of perfect reciprocity by treaty, and with Russia, the Netherlands, Prussia, the free Hanseatic cities, the Dukedom of Oldenburg, and Sardinia by internal regulations on each side, founded on mutual agreement between the respective Governments. The principles upon which the commercial policy of the United States is founded are to be traced to an early period. They are essentially connected with those upon which their independence was declared, and owe their origin to the enlightened men who took the lead in our affairs at that important epoch. They are developed in their first treaty of commerce with France of February 6th, 1778, and by a formal commission which was instituted Immediately after the conclusion of their Revolutionary struggle, for the purpose of negotiating treaties of commerce with every European power. The first treaty of the United States with Prussia, which was negotiated by that commission, affords a signal illustration of those principles. The act of Congress of March 3rd, 1815, adopted immediately after the return of a general peace, was a new overture to foreign nations to establish our commercial relations with them on the basis of free and equal reciprocity. That principle has pervaded all the acts of Congress and all the negotiations of the Executive on the subject. A convention for the settlement of important questions in relation to the North West coast of this continent and its adjoining seas was concluded and signed at St. Petersburg on the 5th day of April last by the minister plenipotentiary of the United States and plenipotentiaries of the Imperial Government of Russia. It will immediately be laid before the Senate for the exercise of the constitutional authority of that body with reference to its ratification. It is proper to add that the manner in which this negotiation was invited and conducted on the part of the Emperor has been very satisfactory.
