The next piece of evidence is General Jackson's letter to Rev. A. J. Crawford, as follows:
["Private.">[
"WASHINGTON, May 1, 1833.
"MY DEAR SIR: * * * I have had a laborious task here, but Nullification is dead; and its actors and courtiers will only be remembered by the People to be execrated for their wicked designs to sever and destroy the only good Government on the globe, and that prosperity and happiness we enjoy over every other portion of the World. Haman's gallows ought to be the fate of all such ambitious men who would involve their Country in Civil War, and all the evils in its train, that they might reign and ride on its whirlwinds and direct the storm. The Free People of these United States have spoken, and consigned these wicked demagogues to their proper doom. Take care of your Nullifiers; you have them among you; let them meet with the indignant frowns of every man who loves his Country. The Tariff, it is now known, was a mere pretext—its burden was on your coarse woolens. By the law of July, 1832, coarse woolen was reduced to five per cent., for the benefit of the South. Mr. Clay's Bill takes it up and classes it with woolens at fifty per cent., reduces it gradually down to twenty per cent., and there it is to remain, and Mr. Calhoun and all the Nullifiers agree to the principle. The cash duties and home valuation will be equal to fifteen per cent. more, and after the year 1842, you pay on coarse woolens thirty-five per cent. If this is not Protection, I cannot understand; therefore the Tariff was only the pretext, and Disunion and a Southern Confederacy the real object. The next pretext will be the Negro or Slavery question.
"My health is not good, but is improving a little. Present me kindly to your lady and family, and believe me to be your friend. I will always be happy to hear from you. "ANDREW JACKSON."
Another evidence is given in the following extract from Benton's "Thirty Years in the Senate," vol. ii., as follows:
"The regular inauguration of this Slavery agitation dates from the year 1835; but it had commenced two years before, and in this way: Nullification and Disunion had commenced in 1830, upon complaint against Protective Tariff. That, being put down in 1833 under President Jackson's proclamation and energetic measures, was immediately substituted by the Slavery agitation. Mr. Calhoun, when he went home from Congress in the spring of that year, told his friends that 'the South could never be united against the North on the Tariff question—that the sugar interest of Louisiana would keep her out—and that the basis of Southern Union must be shifted to the Slave question.' Then all the papers in his interest, and especially the one at Washington, published by Mr. Duff Green, dropped Tariff agitation, and commenced upon Slavery, and in two years had the agitation ripe for inauguration, on the Slavery question. And in tracing this agitation to its present stage, and to comprehend its rationale, it is not to be forgotten that it is a mere continuation of old Tariff Disunion, and preferred because more available."
Again, from p. 490 of his private correspondence, Mr. Clay's words to an Alabamian, in 1844, are thus given:
"From the developments now being made in South Carolina, it is perfectly manifest that a Party exists in that State seeking a Dissolution of the Union, and for that purpose employ the pretext of the rejection of Mr. Tyler's abominable treaty. South Carolina, being surrounded by Slave States, would, in the event of a Dissolution of the Union, suffer only comparative evils; but it is otherwise with Kentucky. She has the boundary of the Ohio extending four hundred miles on three Free States. What would our condition be in the event of the greatest calamity that could befall this Nation?"
Allusion is also made to a letter written by Representative Nathan Appleton, of Boston, December 15, 1860, in which that gentleman said that when he was in Congress—in 1832-33—he had "made up his mind that Messrs. Calhoun, Hayne, McDuffie, etc., were desirous of a separation of the Slave States into a separate Confederacy, as more favorable to the security of Slave Property."
