The Constitution of the United States provides that Congress shall assemble annually on the first Monday of December, and it has been usual for the President to make no communication of a public character to the Senate and House of Representatives until advised of their readiness to receive it. I have deferred to this usage until the close of the first month of the session, but my convictions of duty will not permit me longer to postpone the discharge of the obligation enjoined by the Constitution upon the President "to give to the Congress information of the state of the Union and recommend to their consideration such measures as he shall judge necessary and expedient." It is matter of congratulation that the Republic is tranquilly advancing in a career of prosperity and peace. Whilst relations of amity continue to exist between the United States and all foreign powers, with some of them grave questions are depending which may require the consideration of Congress. Of such questions, the most important is that which has arisen out of the negotiations with Great Britain in reference to Central America. By the convention concluded between the two Governments on the 19th of April, 1850, both parties covenanted that "neither will ever" "occupy, or fortify, or colonize, or assume or exercise any dominion over Nicaragua, Costa Rica, the Mosquito Coast, or any part of Central America." It was the undoubted understanding of the United States in making this treaty that all the present States of the former Republic of Central America and the entire territory of each would thenceforth enjoy complete independence, and that both contracting parties engaged equally and to the same extent, for the present and for the future, that if either then had any claim of right in Central America such claim and all occupation or authority under it were unreservedly relinquished by the stipulations of the convention, and that no dominion was thereafter to be exercised or assumed in any part of Central America by Great Britain or the United States. This Government consented to restrictions in regard to a region of country wherein we had specific and peculiar interests only upon the conviction that the like restrictions were in the same sense obligatory on Great Britain. But for this understanding of the force and effect of the convention it would never have been concluded by us.
