I regret to state that the blockade of the principal ports on the eastern coast of Mexico, which, in consequence of differences between that Republic and France, was instituted in May last, unfortunately still continues, enforced by a competent French naval armament, and is necessarily embarrassing to our own trade in the Gulf, in common with that of other nations. Every disposition, however, is believed to exist on the part of the French Government to render this measure as little onerous as practicable to the interests of the citizens of the United States and to those of neutral commerce, and it is to be hoped that an early settlement of the difficulties between France and Mexico will soon reestablish the harmonious relations formerly subsisting between them and again open the ports of that Republic to the vessels of all friendly nations. A convention for marking that part of the boundary between the United States and the Republic of Texas which extends from the mouth of the Sabine to the Red River was concluded and signed at this city on the 25th of April last. It has since been ratified by both Governments, and seasonable measures will be taken to carry it into effect on the part of the United States. The application of that Republic for admission into this Union, made in August, 1837, and which was declined for reasons already made known to you, has been formally withdrawn, as will appear from the accompanying copy of the note of the minister plenipotentiary of Texas, which was presented to the Secretary of State on the occasion of the exchange of the ratifications of the convention above mentioned. Copies of the convention with Texas, of a commercial treaty concluded with the King of Greece, and of a similar treaty with the Peru-Bolivian Confederation, the ratifications of which have been recently exchanged, accompany this message, for the information of Congress and for such legislative enactments as may be found necessary or expedient in relation to either of them.
