This was then supposed to be the highest bulwark of slavery. Its votaries understood its strength and weakness. Independent, well- paid free labor and industries (46) would ennoble the men of toil, bring wealth and power, build up populous towns and cities, and consequently overwhelm, politically and otherwise, the institution of slavery, or draw into successful social competition with plantation life wealthy inhabitants who knew not slavery and its demoralizing influences. Already, in 1832, the effects of protection on the prosperity of our country were manifest, especially since the Tariff Act of 1828, which levied a duty equivalent to 45 per cent. ad valorem. The Act of 1832 made a small reduction in the duties, but because it was claimed it did not distribute them equally, nullification was determined on as the remedy. It was agreed by the strict constructionists of that day that a State Legislature could not declare a law of the United States void, but to do this the _people_ must speak through a convention. Such a convention met in South Carolina, in November, 1832, and passed a Nullification Ordinance, declaring the tariff acts "null and void," not binding on the State, and that under them no duties should be paid in the State after February 1, 1833. Immediately thereafter medals were struck, inscribed "_John C. Calhoun, first President of the Southern Confederacy_." Nullification, thus proclaimed, was the legitimate forerunner of secession. President Jackson, with his heroic love of the Union, regarded the movement as only _treason;_ he called it that in his proclamations; he prepared to collect the duties in Charleston or to confiscate the cargoes; he warned the nullifiers by the presence of General Scott there that he would be promptly used to coerce the State into loyalty; and he seemed eager to find an excuse for arresting, condemning for treason, and hanging Calhoun, who then went to Washington as a Senator, resigning the Vice-Presidency.(47) Jackson tersely said: "To say that any State may, at pleasure, secede from the Union, is to say that the United States are not a nation." The situation was too imminent for Calhoun's nerves. To confront an indignant nation, led by a fearless, never doubting President, was a different thing then from what it was in 1860-61 with Buchanan as President, surrounded as he was by traitors in his Cabinet. Calhoun and his State backed down, and import duties continued to be collected in South Carolina, although a gradual reduction of them was made an excuse for Calhoun and his friends in Congress, in 1833, to vote for a protective tariff act, so recently before by them declared unconstitutional.(48)
