We will take the existing case of the tariff law. South Carolina is said to have made up her opinion upon it. If we do not repeal it, (as we probably shall not,) she will then apply to the case the remedy of her doctrine. She will, we must suppose, pass a law of her legislature, declaring the several acts of Congress usually called the tariff laws null and void, so far as they respect South Carolina, or the citizens thereof. So far, all is a paper transaction, and easy enough. But the collector at Charleston is collecting the duties imposed by these tariff laws. He, therefore, must be stopped. The collector will seize the goods if the tariff duties are not paid. The State authorities will undertake their rescue, the marshal, with his posse, will come to the collector's aid, and here the contest begins. The militia of the State will be called out to sustain the Nullifying Act. They will march, Sir, under a very gallant leader; for I believe the honorable member himself commands the militia of that part of the State. He will raise the Nullifying Act on his standard, and spread it out as his banner! It will have a preamble, setting forth that the tariff laws are palpable, deliberate, and dangerous violations of the Constitution! He will proceed, with this banner flying, to the custom-house in Charleston, "All the while Sonorous metal blowing martial sounds." Arrived at the custom-house, he will tell the collector that he must collect no more duties under any of the tariff laws. This he will be somewhat puzzled to say, by the way, with a grave countenance, considering what hand South Carolina herself had in that of 1816. But, Sir, the collector would not probably desist, at his bidding. He would show him the law of Congress, the treasury instruction, and his own oath of office. He would say, he should perform his duty, come what come might.
