I have already said, the power to lay duties is given by the Constitution in broad and general terms. There is also conferred on Congress the whole power of regulating commerce, in another distinct provision. Is it clear and palpable, Sir, can any man say it is a case beyond doubt, that, under these two powers, Congress may not justly _discriminate_, in laying duties, _for the purpose of countervailing the policy of foreign nations, or of favoring our own home productions?_ Sir, what ought to conclude this question for ever, as it would seem to me, is, that the regulation of commerce and the imposition of duties are, in all commercial nations, powers avowedly and constantly exercised for this very end. That undeniable truth ought to settle the question; because the Constitution ought to be considered, when it uses well-known language, as using it in its well-known sense. But it is equally undeniable, that it has been, from the very first, fully believed that this power of discrimination was conferred on Congress; and the Constitution was itself recommended, urged upon the people, and enthusiastically insisted on in some of the States, for that very reason. Not that, at that time, the country was extensively engaged in manufactures, especially of the kinds now existing. But the trades and crafts of the seaport towns, the business of the artisans and manual laborers,--those employments, the work in which supplies so great a portion of the daily wants of all classes,--all these looked to the new Constitution as a source of relief from the severe distress which followed the war. It would, Sir, be unpardonable, at so late an hour, to go into details on this point; but the truth is as I have stated. The papers of the day, the resolutions of public meetings, the debates in the conventions, all that we open our eyes upon in the history of the times, prove it.
