Should the proposition thus tendered be rejected we may deprive the United States of the just influence which its acceptance might secure to them, and confer the glory and benefits of being the first among the nations in concluding such an arrangement upon the Government either of Great Britain or France.  That either of these Governments would embrace the offer can not be doubted, because there does not appear to be any other effectual means of securing to all nations the advantages of this important passage but the guaranty of great commercial powers that the Isthmus shall be neutral territory.  The interests of the world at stake are so important that the security of this passage between the two oceans can not be suffered to depend upon the wars and revolutions which may arise among different nations.

Should the Senate in its wisdom see fit to confirm this treaty, and the treaty heretofore submitted by me for their advice in regard to its ratification, negotiated with the State of Nicaragua on the 3d day of September last, it will be necessary to amend one or both of them, so that both treaties may stand in conformity with each other in their spirit and intention.  The Senate will discover by examining them both that this is a task of no great difficulty.

I have good reason to believe that France and Russia stand ready to accede to this treaty, and that no other great maritime state will refuse its accession to an arrangement so well calculated to diffuse the blessings of peace, commerce, and civilization, and so honorable to all nations which may enter into the engagement.

To the House of Representatives of the United States:

I herewith transmit to the House of Representatives copies of a correspondence between the Department of State and the British legation in this city, relative to the reciprocal admission of the natural products of the United States and Canada free of duty into the territories of both countries.  It will be seen by the accompanying documents that the late Secretary of the Treasury recommended, in his correspondence with the Committee on Commerce in the House of Representatives, reciprocal free trade in the natural products of the United States and Canada; that in March and June, 1849, a correspondence was opened between the British charge d’affaires then residing in Washington and the Secretary of State upon the subject of a commercial
