The Post-Office Department occupies a position very different from that of the other Departments. For many years it was the policy of the Government to render this a self-sustaining Department; and if this can not now be accomplished, in the present condition of the country, we ought to make as near an approach to it as may be practicable. The Postmaster-General is placed in a most embarrassing position by the existing laws. He is obliged to carry these into effect. He has no other alternative. He finds, however, that this can not be done without heavy demands upon the Treasury over and above what is received for postage, and these have been progressively increasing from year to year until they amounted for the last fiscal year, ending on the 30th of June, 1858, to more than $4,500,000, whilst it is estimated that for the present fiscal year they will amount to $6,290,000. These sums are exclusive of the annual appropriation of $700,000 for "compensation for the mail service performed for the two Houses of Congress and the other Departments and officers of the Government in the transmission of free matter." The cause of these large deficits is mainly attributable to the increased expense of transporting the mails. In 1852 the sum paid for this service was but a fraction above four millions and a quarter. Since that year it has annually increased, until in 1858 it has reached more than eight millions and a quarter, and for the service of 1859 it is estimated that it will amount to more than $10,000,000. The receipts of the Post-Office Department can be made to approach or to equal its expenditure only by means of the legislation of Congress. In applying any remedy care should be taken that the people shall not be deprived of the advantages which they are fairly entitled to enjoy from the Post-Office Department. The principal remedies recommended to the consideration of Congress by the Postmaster-General are to restore the former rate of postage upon single letters to 5 cents; to substitute for the franking privilege the delivery to those now entitled to enjoy it of post-office stamps for their correspondence, and to direct the Department in making contracts for the transportation of the mail to confine itself to the payment of the sum necessary for this single purpose, without requiring it to be transported in post coaches or carriages of any particular description. Under the present system the expense to the Government is greatly increased by requiring that the mail shall be carried in such vehicles as will accommodate passengers. This will be done, without pay from the Department, over all roads where the travel will remunerate the contractors. These recommendations deserve the grave consideration of Congress.
