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 maximum rate of duty which can be laid for the bona fide purpose of collecting money for the support of Government. To raise the duties higher than that point, and thereby diminish the amount collected, is to levy them for protection merely, and not for revenue. As long, then, as Congress may gradually increase the rate of duty on a given article, and the revenue is increased by such increase of duty, they are within the revenue standard. When they go beyond that point, and as they increase the duties, the revenue is diminished or destroyed; the act ceases to have for its object the raising of money to support Government, but is for protection merely. It does not follow that Congress should levy the highest duty on all articles of import which they will bear within the revenue standard, for such rates would probably produce a much larger amount than the economical administration of the Government would require. Nor does it follow that the duties on all articles should be at the same or a horizontal rate. Some articles will bear a much higher revenue duty than others. Below the maximum of the revenue standard Congress may and ought to discriminate in the rates imposed, taking care so to adjust them on different articles as to produce in the aggregate the amount which, when added to the proceeds of the sales of public lands, may be needed to pay the economical expenses of the Government.

In levying a tariff of duties Congress exercise the taxing power, and for purposes of revenue may select the objects of taxation. They may exempt certain articles altogether and permit their importation free of duty. On others they may impose low duties. In these classes should be embraced such articles of necessity as are in general use, and especially such as are consumed by the laborer and poor as well as by the wealthy citizen. Care should be taken that all the great interests of the country, including manufactures, agriculture, commerce, navigation, and the mechanic arts, should, as far as may be practicable, derive equal advantages from the incidental protection which a just system of revenue duties may afford. Taxation, direct or indirect, is a burden, and it should be so imposed as to operate as equally as may be on all classes in the proportion of their ability to bear it. To make the taxing power an actual benefit to one class necessarily increases the burden of the others beyond their proportion, and would be manifestly unjust. The terms "protection to domestic industry" are of popular import, but they should apply under a just system to all the various branches of industry in our country. The farmer or planter who toils yearly in his fields is engaged in "domestic industry," and is as much entitled to have his labor "protected" as the manufacturer, the man of commerce, the navigator, or the mechanic, who are engaged also in "domestic industry" in their different pursuits. The joint labors of all these classes constitute the aggregate of the "domestic industry" of the nation, and they are equally entitled to the nation's "protection." No one of them can justly claim to be the exclusive recipient of "protection," which can only be afforded by increasing burdens on the "domestic industry" of the others.

If these views be correct, it remains to inquire how far the tariff act of 1842 is consistent with them. That many of the provisions of that act are in violation of the cardinal principles here laid down all must concede. The rates of duty imposed by it on some articles are prohibitory and on others so high as greatly to diminish importations and to produce a less amount of revenue than would be derived from lower rates. They operate as "protection merely" to one branch of "domestic industry" by taxing other branches.

By the introduction of minimums, or assumed and false values, and by the imposition of specific duties the injustice and inequality of the act of 1842 in its practical operations on different classes and pursuits are seen and felt. Many of the oppressive duties imposed by it under the operation of these principles range from 1 per cent to more than 200 per cent. They are prohibitory on some articles and partially so on others, and bear most heavily on articles of common necessity and but lightly on articles of luxury. It is so framed that much the greatest burden which it imposes is thrown on labor and the poorer classes, who are least able to bear it, while it protects capital and exempts the rich from paying their just proportion of the taxation required for the support of Government. While it protects the capital of the wealthy manufacturer and increases his profits, it does not benefit the operatives or laborers in his employment, whose wages have not been increased by it. Articles of prime necessity or of coarse quality and low price, used by the masses of the people, are in many instances subjected by it to heavy taxes, while articles of finer quality and higher price, or of luxury, which can be used only by the opulent, are lightly taxed. It imposes heavy and unjust burdens on the farmer, the planter, the commercial man, and those of all other pursuits except the capitalist who has made his investments in manufactures. All the great interests of the country are not as nearly as may be practicable equally protected by it.

The Government in theory knows no distinction of persons or classes, and should not bestow upon some favors and privileges which all others may not enjoy. It was the purpose of its illustrious founders to base the institutions which they reared upon the great and unchanging principles of justice and equity, conscious that if administered in the spirit in which they were conceived they would be felt only by the benefits which they diffused, and would secure for themselves a defense in the hearts of the people more powerful than standing armies and all the means and appliances invented to sustain governments founded in injustice and oppression.

The well-known fact that the tariff act of 1842 was passed by a majority of one vote in the Senate and two in the House of Representatives, and that some of those who felt themselves constrained, under the peculiar circumstances existing at the time, to vote in its favor, proclaimed its defects and expressed their determination to aid in its modification on the first opportunity, affords strong and conclusive evidence that it was not intended to be permanent, and of the expediency and necessity of its thorough revision.

In recommending to Congress a reduction of the present rates of duty and a revision and modification of the act of 1842, I am far from entertaining opinions unfriendly to the manufacturers. On the contrary, I desire to see them prosperous as far as they can be so without imposing unequal burdens on other interests. The advantage under any system of indirect taxation, even within the revenue standard, must be in favor of the manufacturing interest, and of this no other interest will complain.

I recommend to Congress the abolition of the minimum principle, or assumed, arbitrary, and false values, and of specific duties, and the substitution in their place of ad valorem duties as the fairest and most equitable indirect tax which can be imposed. By the ad valorem principle all articles are taxed according to their cost or value, and those which are of inferior quality or of small cost bear only the just proportion of the tax with those which are of superior quality or greater cost. The articles consumed by all are taxed at the same rate. A system of ad valorem revenue duties, with proper discriminations and proper guards against frauds in collecting them, it is not doubted will afford ample incidental advantages to the manufacturers and enable them to derive as great profits as can be derived from any other regular business. It is believed that such a system strictly within the revenue standard will place the manufacturing interests on a stable footing and inure to their permanent advantage, while it will as nearly as may be practicable extend to all the great interests of the country the incidental protection which can be afforded by our revenue laws. Such a system, when once firmly established, would be permanent, and not be subject to the constant complaints, agitations, and changes which must ever occur when duties are not laid for revenue, but for the "protection merely" of a favored interest.
