The Military Academy forms the basis, in regard to science, on which the military establishment rests. It furnishes annually, after due examination and on the report of the academic staff, many well-informed youths to fill the vacancies which occur in the several corps of the Army, while others who retire to private life carry with them such attainments as, under the right reserved to the several States to appoint the officers and to train the militia, will enable them, by affording a wider field for selection, to promote the great object of the power vested in Congress of providing for the organizing, arming, and disciplining the militia. Thus by the mutual and harmonious cooperation of the two governments in the execution of a power divided between them, an object always to be cherished, the attainment of a great result, on which our liberties may depend, can not fail to be secured. I have to add that in proportion as our regular force is small should the instruction and discipline of the militia, the great resource on which we rely, be pushed to the utmost extent that circumstances will admit. A report from the Secretary of the Navy will communicate the progress which has been made in the construction of vessels of war, with other interesting details respecting the actual state of the affairs of that Department. It has been found necessary for the protection of our commerce to maintain the usual squadrons on the Mediterranean, the Pacific, and along the Atlantic coast, extending the cruises of the latter into the West Indies, where piracy, organized into a system, has preyed on the commerce of every country trading thither. A cruise has also been maintained on the coast of Africa, when the season would permit, for the suppression of the slave trade, and orders have been given to the commanders of all our public ships to seize our own vessels, should they find any engaging in that trade, and to bring them in for adjudication. In the West Indies piracy is of recent date, which may explain the cause why other powers have not combined against it. By the documents communicated it will be seen that the efforts of the United States to suppress it have had a very salutary effect. The benevolent provision of the act under which the protection has been extended alike to the commerce of other nations can not fail to be duly appreciated by them. In compliance with the act of the last session entitled "An act to abolish the United States trading establishments", agents were immediately appointed and instructed, under the direction of the Secretary of the Treasury, to close the business of the trading houses among the Indian tribes and to settle the accounts of the factors and sub-factors engaged in that trade, and to execute in all other respects the injunction of that act in the mode prescribed therein. A final report of their proceedings shall be communicated to Congress as soon as it is received.
