A few years ago our whole national debt growing out of the Revolution and the War of 1812 with Great Britain was extinguished, and we presented to the world the rare and noble spectacle of a great and growing people who had fully discharged every obligation.  Since that time the existing debt has been contracted, and, small as it is in comparison with the similar burdens of most other nations, it should be extinguished at the earliest practicable period.  Should the state of the country permit, and especially if our foreign relations interpose no obstacle, it is contemplated to apply all the moneys in the Treasury as they accrue, beyond what is required for the appropriations by Congress, to its liquidation.  I cherish the hope of soon being able to congratulate the country on its recovering once more the lofty position which it so recently occupied.  Our country, which exhibits to the world the benefits of self-government, in developing all the sources of national prosperity owes to mankind the permanent example of a nation free from the blighting influence of a public debt.

The attention of Congress is invited to the importance of making suitable modifications and reductions of the rates of duty imposed by our present tariff laws.  The object of imposing duties on imports should be to raise revenue to pay the necessary expenses of Government.  Congress may undoubtedly, in the exercise of a sound discretion, discriminate in arranging the rates of duty on different articles, but the discriminations should be within the revenue standard and be made with the view to raise money for the support of Government.

It becomes important to understand distinctly what is meant by a revenue standard the maximum of which should not be exceeded in the rates of duty imposed.  It is conceded, and experience proves, that duties may be laid so high as to diminish or prohibit altogether the importation of any given article, and thereby lessen or destroy the revenue which at lower rates would be derived from its importation.  Such duties exceed the revenue rates and are not imposed to raise money for the support of Government.  If Congress levy a duty for revenue of 1 per cent on a given article, it will produce a given amount of money to the Treasury and will incidentally and necessarily afford protection or advantage to the amount of 1 per cent to the home manufacturer of a similar or like article over the importer.  If the duty be raised to 10 per cent, it will produce a greater amount of money and afford greater protection.  If it be still raised to 20, 25, or 30 per cent, and if as it is raised the revenue derived from it is found to be increased, the protection or advantage will also be increased; but if it be raised to 31 per cent, and it is found that the revenue produced at that rate is less than at 30 per cent, it ceases to be a revenue duty.  The precise point in the ascending scale of duties at which it is ascertained from experience that the revenue is greatest is the
