For thirteen fortifications erecting on various points of our Atlantic coast, from Rhode Island to Louisiana, the aggregate expenditure of the year has fallen little short of $1,000,000. For the preparation of five additional reports of reconnoissances and surveys since the last session of Congress, for the civil construction upon 37 different public works commenced, eight others for which specific appropriations have been made by acts of Congress, and twenty other incipient surveys under the authority given by the act of April 30th, 1824, about $1,000,000 more has been drawn from the Treasury.

To these $2,000,000 is to be added the appropriation of $250,000 to commence the erection of a break-water near the mouth of the Delaware River, the subscriptions to the Delaware and Chesapeake, the Louisville and Portland, the Dismal Swamp, and the Chesapeake and Ohio canals, the large donations of lands to the States of Ohio, Indiana, Illinois, and Alabama for objects of improvements within those States, and the sums appropriated for light-houses, buoys, and piers on the coast; and a full view will be taken of the munificence of the nation in the application of its resources to the improvement of its own condition.

Of these great national under-takings the Academy at West Point is among the most important in itself and the most comprehensive in its consequences. In that institution a part of the revenue of the nation is applied to defray the expense of educating a competent portion of her youth chiefly to the knowledge and the duties of military life. It is the living armory of the nation. While the other works of improvement enumerated in the reports now presented to the attention of Congress are destined to ameliorate the face of nature, to multiply the facilities of communication between the different parts of the Union, to assist the labors, increase the comforts, and enhance the enjoyments of individuals, the instruction acquired at West Point enlarges the dominion and expands the capacities of the mind. Its beneficial results are already experienced in the composition of the Army, and their influence is felt in the intellectual progress of society. The institution is susceptible still of great improvement from benefactions proposed by several successive Boards of Visitors, to whose earnest and repeated recommendations I cheerfully add my own.

With the usual annual reports from the Secretary of the Navy and the Board of Commissioners will be exhibited to the view of Congress the execution of the laws relating to that department of the public service. The repression of piracy in the West Indian and in the Grecian seas has been effectually maintained, with scarcely any exception. During the war between the Governments of Buenos Ayres and of Brazil frequent collisions between the belligerent acts of power and the rights of neutral commerce occurred. Licentious blockades, irregularly enlisted or impressed sea men, and the property of honest commerce seized with violence, and even plundered under legal pretenses, are disorders never separable from the conflicts of war upon the ocean.

With a portion of them the correspondence of our commanders on the eastern aspect of the South American coast and among the islands of Greece discover how far we have been involved. In these the honor of our country and the rights of our citizens have been asserted and vindicated. The appearance of new squadrons in the Mediterranean and the blockade of the Dardanelles indicate the danger of other obstacles to the freedom of commerce and the necessity of keeping our naval force in those seas. To the suggestions repeated in the report of the Secretary of the Navy, and tending to the permanent improvement of this institution, I invite the favorable consideration of Congress.

A resolution of the House of Representatives requesting that one of our small public vessels should be sent to the Pacific Ocean and South Sea to examine the coasts, islands, harbors, shoals, and reefs in those seas, and to ascertain their true situation and description, has been put in a train of execution. The vessel is nearly ready to depart. The successful accomplishment of the expedition may be greatly facilitated by suitable legislative provisions, and particularly by an appropriation to defray its necessary expense. The addition of a 2nd, and perhaps a 3rd, vessel, with a slight aggravation of the cost, would contribute much to the safety of the citizens embarked on this under- taking, the results of which may be of the deepest interest to our country.

With the report of the Secretary of the Navy will be submitted, in conformity to the act of Congress of March 3d, 1827, for the gradual improvement of the Navy of the United States, statements of the expenditures under that act and of the measures for carrying the same into effect. Every section of that statute contains a distinct provision looking to the great object of the whole--the gradual improvement of the Navy. Under its salutary sanction stores of ship timber have been procured and are in process of seasoning and preservation for the future uses of the Navy. Arrangements have been made for the preservation of the live oak timber growing on the lands of the United States, and for its reproduction, to supply at future and distant days the waste of that most valuable material for ship building by the great consumption of it yearly for the commercial as well as for the military marine of our country.

The construction of the two dry docks at Charlestown and at Norfolk is making satisfactory progress toward a durable establishment. The examinations and inquiries to ascertain the practicability and expediency of a marine railway at Pensacola, though not yet accomplished, have been postponed but to be more effectually made. The navy yards of the United States have been examined, and plans for their improvement and the preservation of the public property therein at Portsmouth, Charlestown, Philadelphia, Washington, and Gosport, and to which two others are to be added, have been prepared and received my sanction; and no other portion of my public duties has been performed with a more intimate conviction of its importance to the future welfare and security of the Union.

With the report from the Post Master General is exhibited a comparative view of the gradual increase of that establishment, from five to five years, since 1792 'til this time in the number of post offices, which has grown from less than 200 to nearly 8,000; in the revenue yielded by them, which from $67,000 has swollen to upward of $1,500,000, and in the number of miles of post roads, which from 5,642 have multiplied to 114,536. While in the same period of time the population of the Union has about thrice doubled, the rate of increase of these offices is nearly 40, and of the revenue and of traveled miles from 20 to 25 for one. The increase of revenue within the last five years has been nearly equal to the whole revenue of the Department in 1812.

The expenditures of the Department during the year which ended on July 1st, 1828 have exceeded the receipts by a sum of about $25,000. The excess has been occasioned by the increase of mail conveyances and facilities to the extent of near 800,000 miles. It has been supplied by collections from the post masters of the arrearages of preceding years. While the correct principle seems to be that the income levied by the Department should defray all its expenses, it has never been the policy of this Government to raise from this establishment any revenue to be applied to any other purposes. The suggestion of the Post Master General that the insurance of the safe transmission of moneys by the mail might be assumed by the Department for a moderate and competent remuneration will deserve the consideration of Congress.
