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and the best information respecting the views of those powers it is distinctly understood that should our squadron be withdrawn they would soon recommence their hostilities and depredations upon our commerce.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
