Long and patient reflection has strengthened the opinions I have heretofore expressed to Congress on this subject, and I deem it my duty on the present occasion again to urge them upon the attention of the Legislature. The soundest maxims of public policy and the principles upon which our republican institutions are founded recommend a proper adaptation of the revenue to the expenditure, and they also require that the expenditure shall be limited to what, by an economical administration, shall be consistent with the simplicity of the Government and necessary to an efficient public service. In effecting this adjustment it is due, in justice to the interests of the different States, and even to the preservation of the Union itself, that the protection afforded by existing laws to any branches of the national industry should not exceed what may be necessary to counteract the regulations of foreign nations and to secure a supply of those articles of manufacture essential to the national independence and safety in time of war. If upon investigation it shall be found, as it is believed it will be, that the legislative protection granted to any particular interest is greater than is indispensably requisite for these objects, I recommend that it be gradually diminished, and that as far as may be consistent with these objects the whole scheme of duties be reduced to the revenue standard as soon as a just regard to the faith of the Government and to the preservation of the large capital invested in establishments of domestic industry will permit. That manufactures adequate to the supply of our domestic consumption would in the abstract be beneficial to our country there is no reason to doubt, and to effect their establishment there is perhaps no American citizen who would not for awhile be willing to pay a higher price for them. But for this purpose it is presumed that a tariff of high duties, designed for perpetual protection, has entered into the minds of but few of our statesmen. The most they have anticipated is a temporary and, generally, incidental protection, which they maintain has the effect to reduce the price by domestic competition below that of the foreign article. Experience, however, our best guide on this as on other subjects, makes it doubtful whether the advantages of this system are not counterbalanced by many evils, and whether it does not tend to beget in the minds of a large portion of our countrymen a spirit of discontent and jealousy dangerous to the stability of the Union.
