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.
