There are just grounds to believe that the improvement which has occurred in the revenue during the last-mentioned period will not only be maintained, but that it will progressively increase through the next and several succeeding years, so as to realize the results which were presented upon that subject by the official reports of the Treasury at the commencement of the last session of Congress.

Under the influence of the most unfavorable circumstances the revenue for the next and subsequent years to the year 1825 will exceed the demands at present authorized by law.

It may fairly be presumed that under the protection given to domestic manufactures by the existing laws we shall become at no distant period a manufacturing country on an extensive scale. Possessing as we do the raw materials in such vast amount, with a capacity to augment them to an indefinite extent; raising within the country aliment of every kind to an amount far exceeding the demand for home consumption, even in the most unfavorable years, and to be obtained always at a very moderate price; skilled also, as our people are, in the mechanic arts and in every improvement calculated to lessen the demand for and the price of labor, it is manifest that their success in every branch of domestic industry may and will be carried, under the encouragement given by the present duties, to an extent to meet any demand which under a fair competition may be made upon it.

A considerable increase of domestic manufactures, by diminishing the importation of foreign, will probably tend to lessen the amount of the public revenue. As, however, a large proportion of the revenue which is derived from duties is raised from other articles than manufactures, the demand for which will increase with our population, it is believed that a fund will still be raised from that source adequate to the greater part of the public expenditures, especially as those expenditures, should we continue to be blessed with peace, will be diminished by the completion of the fortifications, dockyards, and other public works, by the augmentation of the Navy to the point to which it is proposed to carry it, and by the payment of the public debt, including pensions for military services.

It can not be doubted that the more complete our internal resources and the less dependent we are on foreign powers for every national as well as domestic purpose the greater and more stable will be the public felicity. By the increase of domestic manufactures will the demand for the rude materials at home be increased, and thus will the dependence of the several parts of our Union on each other and the strength of the Union itself be proportionably augmented. In this process, which is very desirable, and inevitable under the existing duties, the resources which obviously present themselves to supply a deficiency in the revenue, should it occur, are the interests which may derive the principal benefit from the change. If domestic manufactures are raised by duties on foreign, the deficiency in the fund necessary for public purposes should be supplied by duties on the former. At the last session it seemed doubtful whether the revenue derived from the present sources would be adequate to all the great purposes of our Union, including the construction of our fortifications, the augmentation of the Navy, and the protection of our commerce against the dangers to which it is exposed. Had the deficiency been such as to subject us to the necessity either to abandon those measures of defense or to resort to other means for adequate funds, the course presented to the adoption of a virtuous and enlightened people appeared to be a plain one. It must be gratifying to all to know that this necessity does not exist. Nothing, however, in contemplation of such important objects, which can be easily provided for, should be left to hazard. It is thought that the revenue may receive an augmentation from the existing sources, and in a manner to aid our manufactures, without hastening prematurely the result which has been suggested. It is believed that a moderate additional duty on certain articles would have that effect, without being liable to any serious objection.

The examination of the whole coast, for the construction of permanent fortifications, from St. Croix to the Sabine, with the exception of part of the territory lately acquired, will be completed in the present year, as will be the survey of the Mississippi, under the resolution of the House of Representatives, from the mouth of the Ohio to the ocean, and likewise of the Ohio from Louisville to the Mississippi. A progress corresponding with the sums appropriated has also been made in the construction of these fortifications at the points designated. As they will form a system of defense for the whole maritime frontier, and in consequence for the interior, and are to last for ages, the greatest care has been taken to fix the position of each work and to form it on such a scale as will be adequate to the purpose intended by it. All the inlets and assailable parts of our Union have been minutely examined, and positions taken with a view to the best effect, observing in every instance a just regard for economy. Doubts, however, being entertained as to the propriety of the position and extent of the work at Dauphine Island, further progress in it was suspended soon after the last session of Congress, and an order given to the Board of Engineers and Naval Commissioners to make a further and more minute examination of it in both respects, and to report the result without delay.

Due progress has been made in the construction of vessels of war according to the law providing for the gradual augmentation of the Navy, and to the extent of existing appropriations. The vessels authorized by the act of 1820 have all been completed and are now in actual service. None of the larger ships have been or will be launched for the present, the object being to protect all which may not be required for immediate service from decay by suitable buildings erected over them. A squadron has been maintained, as heretofore, in the Mediterranean, by means whereof peace has been preserved with the Barbary Powers. This squadron has been reduced the present year to as small a force as is compatible with the fulfillment of the object intended by it. From past experience and the best information respecting the views of those powers it is distinctly understood that should our squadron be withdrawn they would soon recommence their hostilities and depredations upon our commerce. Their fortifications have lately been rebuilt and their maritime force increased. It has also been found necessary to maintain a naval force on the Pacific for the protection of the very important interests of our citizens engaged in commerce and the fisheries in that sea. Vessels have likewise been employed in cruising along the Atlantic coast, in the Gulf of Mexico, on the coast of Africa, and in the neighboring seas. In the latter many piracies have been committed on our commerce, and so extensive was becoming the range of those unprincipled adventurers that there was cause to apprehend, without a timely and decisive effort to suppress them, the worst consequences would ensue. Fortunately, a considerable check has been given to that spirit by our cruisers, who have succeeded in capturing and destroying several of their vessels. Nevertheless, it is considered an object of high importance to continue these cruises until the practice is entirely suppressed. Like success has attended our efforts to suppress the slave trade. Under the flag of the United States and the sanction of their papers the trade may be considered as entirely suppressed, and if any of our citizens are engaged in it under the flags and papers of other powers, it is only from a respect to the rights of those powers that these offenders are not seized and brought home to receive the punishment which the laws inflict. If every other power should adopt the same policy and pursue the same vigorous means for carrying it into effect, the trade could no longer exist.

Deeply impressed with the blessings which we enjoy, and of which we have such manifold proofs, my mind is irresistibly drawn to that Almighty Being, the great source from whence they proceed and to whom our most grateful acknowledgments are due.
