During the past year there have been employed, under contracts with the Post-Office Department, two ocean steamers in conveying the mails monthly between New York and Bremen, and one, since October last, performing semimonthly service between Charleston and Havana; and a contract has been made for the transportation of the Pacific mails across the Isthmus from Chagres to Panama.

Under the authority given to the Secretary of the Navy, three ocean steamers have been constructed and sent to the Pacific, and are expected to enter upon the mail service between Panama and Oregon and the intermediate ports on the 1st of January next; and a fourth has been engaged by him for the service between Havana and Chagres, so that a regular monthly mail line will be kept up after that time between the United States and our territories on the Pacific.

Notwithstanding this great increase in the mail service, should the revenue continue to increase the present year as it did in the last, there will be received near $450,000 more than the expenditures.

These considerations have satisfied the Postmaster-General that, with certain modifications of the act of 1845, the revenue may be still further increased and a reduction of postages made to a uniform rate of 5 cents, without an interference with the principle, which has been constantly and properly enforced, of making that Department sustain itself.

A well-digested cheap-postage system is the best means of diffusing intelligence among the people, and is of so much importance in a country so extensive as that of the United States that I recommend to your favorable consideration the suggestions of the Postmaster-General for its improvement.

Nothing can retard the onward progress of our country and prevent us from assuming and maintaining the first rank among nations but a disregard of the experience of the past and a recurrence to an unwise public policy. We have just closed a foreign war by an honorable peace--a war rendered necessary and unavoidable in vindication of the national rights and honor. The present condition of the country is similar in some respects to that which existed immediately after the close of the war with Great Britain in 1815, and the occasion is deemed to be a proper one to take a retrospect of the measures of public policy which followed that war. There was at that period of our history a departure from our earlier policy. The enlargement of the powers of the Federal Government by construction, which obtained, was not warranted by any just interpretation of the Constitution. A few years after the close of that war a series of measures was adopted which, united and combined, constituted what was termed by their authors and advocates the “American system.”

The introduction of the new policy was for a time favored by the condition of the country, by the heavy debt which had been contracted during the war, by the depression of the public credit, by the deranged state of the finances and the currency, and by the commercial and pecuniary embarrassment which extensively prevailed. These were not the only causes which led to its establishment. The events of the war with Great Britain and the embarrassments which had attended its prosecution had left on the minds of many of our statesmen the impression that our Government was not strong enough, and that to wield its resources successfully in great emergencies, and especially in war, more power should be concentrated in its hands. This increased power they did not seek to obtain by the legitimate and prescribed mode--an amendment of the Constitution--but by construction. They saw Governments in the Old World based upon different orders of society, and so constituted as to throw the whole power of nations into the hands of a few, who taxed and controlled the many without responsibility or restraint. In that arrangement they conceived the strength of nations in war consisted. There was also something fascinating in the ease, luxury, and display of the higher orders, who drew their wealth from the toil of the laboring millions. The authors of the system drew their ideas of political economy from what they had witnessed in Europe, and particularly in Great Britain. They had viewed the enormous wealth concentrated in few hands and had seen the splendor of the overgrown establishments of an aristocracy which was upheld by the restrictive policy. They forgot to look down upon the poorer classes of the English population, upon whose daily and yearly labor the great establishments they so much admired were sustained and supported. They failed to perceive that the scantily fed and half-clad operatives were not only in abject poverty, but were bound in chains of oppressive servitude for the benefit of favored classes, who were the exclusive objects of the care of the Government.

It was not possible to reconstruct society in the United States upon the European plan. Here there was a written Constitution, by which orders and titles were not recognized or tolerated. A system of measures was therefore devised, calculated, if not intended, to withdraw power gradually and silently from the States and the mass of the people, and by construction to approximate our Government to the European models, substituting an aristocracy of wealth for that of orders and titles.

Without reflecting upon the dissimilarity of our institutions and of the condition of our people and those of Europe, they conceived the vain idea of building up in the United States a system similar to that which they admired abroad. Great Britain had a national bank of large capital, in whose hands was concentrated the controlling monetary and financial power of the nation--an institution wielding almost kingly power, and exerting vast influence upon all the operations of trade and upon the policy of the Government itself. Great Britain had an enormous public debt, and it had become a part of her public policy to regard this as a “public blessing.” Great Britain had also a restrictive policy, which placed fetters and burdens on trade and trammeled the productive industry of the mass of the nation. By her combined system of policy the landlords and other property holders were protected and enriched by the enormous taxes which were levied upon the labor of the country for their advantage. Imitating this foreign policy, the first step in establishing the new system in the United States was the creation of a national bank. Not foreseeing the dangerous power and countless evils which such an institution might entail on the country, nor perceiving the connection which it was designed to form between the bank and the other branches of the miscalled “American system,” but feeling the embarrassments of the Treasury and of the business of the country consequent upon the war, some of our statesmen who had held different and sounder views were induced to yield their scruples and, indeed, settled convictions of its unconstitutionality, and to give it their sanction as an expedient which they vainly hoped might produce relief. It was a most unfortunate error, as the subsequent history and final catastrophe of that dangerous and corrupt institution have abundantly proved. The bank, with its numerous branches ramified into the States, soon brought many of the active political and commercial men in different sections of the country into the relation of debtors to it and dependents upon it for pecuniary favors, thus diffusing throughout the mass of society a great number of individuals of power and influence to give tone to public opinion and to act in concert in cases of emergency. The corrupt power of such a political engine is no longer a matter of speculation, having been displayed in numerous instances, but most signally in the political struggles of 1832, 1833, and 1834 in opposition to the public will represented by a fearless and patriotic President.

But the bank was but one branch of the new system. A public debt of more than $120,000,000 existed, and it is not to be disguised that many of the authors of the new system did not regard its speedy payment as essential to the public prosperity, but looked upon its continuance as no national evil. Whilst the debt existed it furnished aliment to the national bank and rendered increased taxation necessary to the amount of the interest, exceeding $7,000,000 annually.
