I affirm, then, that there exists in the United States a slave trade, not less odious or demoralising, nay, I do in my conscience believe, more odious and more demoralising than that which is carried on between Africa and Brazil. North Carolina and Virginia are to Louisiana and Alabama what Congo is to Rio Janeiro. The slave States of the Union are divided into two classes, the breeding States, where the human beasts of burden increase and multiply and become strong for labour, and the sugar and cotton States to which those beasts of burden are sent to be worked to death. To what an extent the traffic in man is carried on we may learn by comparing the census of 1830 with the census of 1840. North Carolina and Virginia are, as I have said, great breeding States. During the ten years from 1830 to 1840 the slave population of North Carolina was almost stationary. The slave population of Virginia positively decreased. Yet, both in North Carolina and Virginia propagation was, during those ten years, going on fast. The number of births among the slaves in those States exceeded by hundreds of thousands the number of the deaths. What then became of the surplus? Look to the returns from the Southern States, from the States whose produce the right honourable Baronet proposes to admit with reduced duty or with no duty at all; and you will see. You will find that the increase in the breeding States was barely sufficient to meet the demand of the consuming States. In Louisiana, for example, where we know that the negro population is worn down by cruel toil, and would not, if left to itself, keep up its numbers, there were, in 1830, one hundred and seven thousand slaves; in 1840, one hundred and seventy thousand. In Alabama, the slave population during those ten years much more than doubled; it rose from one hundred and seventeen thousand to two hundred and fifty-three thousand. In Mississippi it actually tripled. It rose from sixty-five thousand to one hundred and ninety-five thousand. So much for the extent of this slave trade. And as to its nature, ask any Englishman who has ever travelled in the Southern States. Jobbers go about from plantation to plantation looking out for proprietors who are not easy in their circumstances, and who are likely to sell cheap. A black boy is picked up here; a black girl there. The dearest ties of nature and of marriage are torn asunder as rudely as they were ever torn asunder by any slave captain on the coast of Guinea. A gang of three or four hundred negroes is made up; and then these wretches, handcuffed, fettered, guarded by armed men, are driven southward, as you would drive,--or rather as you would not drive,--a herd of oxen to Smithfield, that they may undergo the deadly labour of the sugar mill near the mouth of the Mississippi. A very few years of that labour in that climate suffice to send the stoutest African to his grave. But he can well be spared. While he is fast
