A report from the Postmaster-General is likewise communicated, presenting in a highly satisfactory manner the result of a vigorous, efficient, and economical administration of that Department. The revenue of the office, even of the year including the latter half of 1824 and the first half of 1825, had exceeded its expenditures by a sum of more than $45,000. That of the succeeding year has been still more productive. The increase of the receipts in the year preceding the 1st of July last over that of the year before exceeds $136,000, and the excess of the receipts over the expenditures of the year has swollen from $45,000 to nearly $80,000. During the same period contracts for additional transportation of the mail in stages for about 260,000 miles have been made, and for 70,000 miles annually on horseback. Seven hundred and fourteen new post-offices have been established within the year, and the increase of revenue within the last three years, as well as the augmentation of the transportation by mail, is more than equal to the whole amount of receipts and of mail conveyance at the commencement of the present century, when the seat of the General Government was removed to this place. When we reflect that the objects effected by the transportation of the mail are among the choicest comforts and enjoyments of social life, it is pleasing to observe that the dissemination of them to every corner of our country has outstripped in their increase even the rapid march of our population. By the treaties with France and Spain, respectively ceding Louisiana and the Floridas to the United States, provision was made for the security of land titles derived from the Governments of those nations. Some progress has been made under the authority of various acts of Congress in the ascertainment and establishment of those titles, but claims to a very large extent remain unadjusted. The public faith no less than the just rights of individuals and the interest of the community itself appears to require further provision for the speedy settlement of those claims, which I therefore recommend to the care and attention of the Legislature. In conformity with the provisions of the act of 20th May last, to provide for erecting a penitentiary in the district of Columbia, and for other purposes, three commissioners were appointed to select a site for the erection of a penitentiary for the district, and also a site in the county of Alexandria for a county jail, both of which objects have been effected. The building of the penitentiary has been commenced, and is in such a degree of forwardness as to promise that it will be completed before the meeting of the next Congress. This consideration points to the expediency of maturing at the present session a system for the regulation and government of the penitentiary, and of defining the class of offenses which shall be punishable by confinement in this edifice.
