"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." After mentioning that "About 1835, some South Carolinians attempted a Disunion demonstration," our authority says: It is thus described by ex-Governor Francis Thomas of Maryland, in his speech in Baltimore, October 29, 1861: "Full twenty years ago, when occupying my seat in the House of Representatives, I was surprised one morning, after the assembling of the House, to observe that all the members from the Slaveholding States were absent. Whilst reflecting on this strange occurrence, I was asked why I was not in attendance on the Southern Caucus assembled in the room of the Committee on Claims. I replied that I had received no invitation.
