The diplomatic difficulties which existed between the Government of the United States and that of Great Britain at the adjournment of the last Congress have been happily terminated by the appointment of a British minister to this country, who has been cordially received. Whilst it is greatly to the interest, as I am convinced it is the sincere desire, of the Governments and people of the two countries to be on terms of intimate friendship with each other, it has been our misfortune almost always to have had some irritating, if not dangerous, outstanding question with Great Britain. Since the origin of the Government we have been employed in negotiating treaties with that power, and afterwards in discussing their true intent and meaning. In this respect the convention of April 19, 1850, commonly called the Clayton and Bulwer treaty, has been the most unfortunate of all, because the two Governments place directly opposite and contradictory constructions upon its first and most important article. Whilst in the United States we believed that this treaty would place both powers upon an exact equality by the stipulation that neither will ever "occupy, or fortify, or colonize, or assume, or exercise any dominion" over any part of Central America, it is contended by the British Government that the true construction of this language has left them in the rightful possession of all that portion of Central America which was in their occupancy at the date of the treaty; in fact, that the treaty is a virtual recognition on the part of the United States of the right of Great Britain, either as owner or protector, to the whole extensive coast of Central America, sweeping round from the Rio Hondo to the port and harbor of San Juan de Nicaragua, together with the adjacent Bay Islands, except the comparatively small portion of this between the Sarstoon and Cape Honduras. According to their construction, the treaty does no more than simply prohibit them from extending their possessions in Central America beyond the present limits. It is not too much to assert that if in the United States the treaty had been considered susceptible of such a construction it never would have been negotiated under the authority of the President, nor would it have received the approbation of the Senate. The universal conviction in the United States was that when our Government consented to violate its traditional and time-honored policy and to stipulate with a foreign government never to occupy or acquire territory in the Central American portion of our own continent, the consideration for this sacrifice was that Great Britain should, in this respect at least, be placed in the same position with ourselves. Whilst we have no right to doubt the sincerity of the British Government in their construction of the treaty, it is at the same time my deliberate conviction that this construction is in opposition both to its letter and its spirit.
