 522 would all be within the scope of the power; for all of them bear an intimate relation to commerce. The result would be, that the powers of congress would embrace the widest extent of legislative functions, to the utter demolition of all constitutional boundaries between the state and national governments. When duties are laid, not for purposes of revenue, but of retaliation and restriction, to countervail foreign restrictions, they are strictly within the scope of the power, as a regulation of commerce. But when laid to encourage manufactures, they have nothing to do with it. The power to regulate manufactures is no more confided to congress, than the power to interfere with the systems of education, the poor laws, or the road laws of the states. It is notorious, that, in the convention, an attempt was made to introduce into the constitution a power to encourage manufactures; but it was withheld. In stead of granting the power to congress, permission was given to the states to impose duties, with the consent of that body, to encourage their own manufactures; and thus, in the true spirit of justice, imposing the burthen on those, who were to be benefited. It is true, that congress may, incidentally, when laying duties for revenue, consult the other interests of the country. They may so arrange the details, as indirectly to aid manufactures. And this is the whole extent, to which congress has ever gone until the tariffs, which have given rise to the present controversy. The former precedents of congress are not, even if admitted to be authoritative, applicable to the question now presented.
