"Python" (a pseudonym for John Tyler, Jr., son of the former president) in *De Bow's Review* in 1859 on how the "Sewardites" if they got control of the federal government could emancipate the slaves:
"Perverting that clause of the Constitution declaring that 'private property shall not be taken for public use without just compensation,' a clause the abolitionists proper would deny, as bearing on the question of property in negro slaves as they negate altogether such right of property, but which Sewardism readily admits and will apply to the case — Congress will declare the value of the slaves remaining to the South, and the government, through its agents, will take possession of them, transferring to itself the original right of property resident in their former owners. *Thus will emancipation be initiated.* But the negroes will now be told they belong to the government, having been bought for a price ; and that after serving the government for ten years, to pay back their purchase money, they shall be free and equal. *Thus will the apprentice system be established.*..." https://books.google.com/books?id=hK42AQAAMAAJ&pg=PA260
What frightens "Python" most about this scenario is that he thinks it will be attractive to everyone, North and South, except the slaveholders and their families (who will be reduced to beggary) and to the "emancipated" slaves themselves (who, he argues, will be driven so hard by their new northern capitalist masters that they will never live to see the end of their apprenticeship)...
(This is certainly the most imaginative--though hardly the most plausible--answer I have seen from any secessionists to the question of just how the "Black Republicans" if they took power in Washington could end slavery--at least in its then-existing from--in the South. BTW, a fascinating detail: John Tyler, Jr. became a Republican after the ACW ! So did a lot of ex-Confederates for a while, to be sure, but most of them returned to the Democracy before long. But Tyler, Jr. stuck with the Republicans; in 1880, he was still writing to President Hayes about "destroying Bourbonism, and breaking up the solidarity of the South." https://books.google.com/books?id=rTK1N6owT1YC&pg=PA99)
