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into this Union, made in August, 1837, and which was declined for reasons already made known to you, has been formally withdrawn, as will appear from the accompanying copy of the note of the minister plenipotentiary of Texas, which was presented to the Secretary of State on the occasion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.

To watch over and foster the interests of a gradually increasing and widely extended commerce, to guard the rights of American citizens whom business or pleasure or other motives may tempt into distant climes, and at the same time to cultivate those sentiments of mutual respect and good will which experience has proved so beneficial in international intercourse, the Government of the United States has deemed it expedient from time to time to establish diplomatic connections with different foreign states, by the appointment of representatives to reside within their respective territories. I am gratified to be enabled to announce to you that since the close of your last session these relations have been opened under the happiest auspices with Austria and the Two Sicilies, that new nominations have been made in the respective missions of Russia, Brazil, Belgium, and Sweden and Norway in this country, and that a minister extraordinary has been received, accredited to this Government, from the Argentine Confederation.

An exposition of the fiscal affairs of the Government and of their condition for the past year will be made to you by the Secretary of the Treasury.

The available balance in the Treasury on the 1st of January next is estimated at $2,765,342. The receipts of the year from customs and lands will probably amount to $20,615,598. These usual sources of revenue have been increased by an issue of Treasury notes, of which less than $8,000,000, including interest and principal, will be outstanding at the end of the year, and by the sale of one of the bonds of the Bank of the United States for $2,254,871. The aggregate of means from these and other sources, with the balance on hand on the 1st of January last, has been applied to the payment of appropriations by Congress. The whole expenditure for the year on their account, including the redemption of more than eight millions of Treasury notes, constitutes an aggregate of about $40,000,000, and will still leave in the Treasury the balance before stated.

Nearly $8,000,000 of Treasury notes are to be paid during the coming year in addition to the ordinary appropriations for the support of Government. For both these purposes the resources of the Treasury will undoubtedly be sufficient if the charges upon it are not increased beyond the annual estimates. No excess, however, is likely to exist. Nor can the postponed installment of the surplus revenue be deposited with the States nor any considerable appropriations beyond the estimates be made without causing a deficiency in the Treasury. The great caution, advisable at all times, of limiting appropriations to the wants of the public service is rendered necessary at present by the prospective and rapid reduction of the tariff, while the vigilant jealousy evidently excited among the people by the occurrences of the last few years assures us that they expect from their representatives, and will sustain them in the exercise of, the most rigid economy. Much can be effected by postponing appropriations not immediately required for the ordinary public service or for any pressing emergency, and much by reducing the expenditures where the entire and immediate accomplishment of the objects in view is not indispensable.

When we call to mind the recent and extreme embarrassments produced by excessive issues of bank paper, aggravated by the unforeseen withdrawal of much foreign capital and the inevitable derangement arising from the distribution of the surplus revenue among the States as required by Congress, and consider the heavy expenses incurred by the removal of Indian tribes, by the military operations in Florida, and on account of the unusually large appropriations made at the last two annual sessions of Congress for other objects, we have striking evidence in the present efficient state of our finances of the abundant resources of the country to fulfill all its obligations. Nor is it less gratifying to find that the general business of the community, deeply affected as it has been, is reviving with additional vigor, chastened by the lessons of the past and animated by the hopes of the future. By the curtailment of paper issues, by curbing the sanguine and adventurous spirit of speculation, and by the honorable application of all available means to the fulfillment of obligations, confidence has been restored both at home and abroad, and ease and facility secured to all the operations of trade.

The agency of the Government in producing these results has been as efficient as its powers and means permitted. By withholding from the States the deposit of the fourth installment, and leaving several millions at long credits with the banks, principally in one section of the country, and more immediately beneficial to it, and at the same time aiding the banks and commercial communities in other sections by postponing the payment of bonds for duties to the amount of between four and five millions of dollars; by an issue of Treasury notes as a means to enable the Government to meet the consequences of their indulgences, but affording at the same time facilities for remittance and exchange; and by steadily declining to employ as general depositories of the public revenues, or receive the notes of, all banks which refused to redeem them with specie--by these measures, aided by the favorable action of some of the banks and by the support and cooperation of a large portion of the community, we have witnessed an early resumption of specie payments in our great commercial capital, promptly followed in almost every part of the United States. This result has been alike salutary to the true interests of agriculture, commerce, and manufactures; to public morals, respect for the laws, and that confidence between man and man which is so essential in all our social relations.
