and the chief opponents of schemes of internal improvement based their dissent upon a careful meditation of the language of the Constitution. Without its plain approval they would not move, even if they had to stand still all their days. It was, too, with many professions of this spirit that the tariff was dealt with. It ran suddenly to the front as a militant party question in 1833, not as if a great free-trade movement had been set afoot which was to anticipate the mission of Cobden and Bright, but as an issue between federal taxation and the constitutional privileges of the States. The agricultural States were being, as they thought, very cruelly trodden down under the iron heel of that protectionist policy to whose enthronement they had themselves consented, and they fetched their hope of escape from the Constitution. The federal government unquestionably possessed, they admitted, and that by direct grant of the fundamental law, the right to impose duties on imports; but did that right carry with it the privilege of laying discriminating duties for other purposes than that of raising legitimate revenue? Could the Constitution have meant that South Carolina might be taxed to maintain the manufactures of New England? Close upon the heels of the great tariff controversy of that time came the stupendous contest over the right of secession and the abolition of slavery; and again in this contest, as in all that had gone before, the party which was being hard driven sought refuge in the Constitution. This too was, in its first stages at least, a lawyer's question. It eventually slipped out of all lawyerly control, and was given over to be settled by the stern and savage processes of war; but it stayed with the constitutional lawyers as long as it could, and would have stayed with them to the end had it not itself been bigger than the Constitution and mixed with such interests and such passions as were beyond the control of legislatures or of law courts.
