MR. BURT, of South Carolina, rose and said that he had not interrupted the gentleman from Massachusetts during his speech, but he presumed he did not wish to have any error go forth under the sanction of his name; and he therefore called upon him to retract what he had said in regard to slaves ever being exempted from capital punishment for crimes for which the whites were executed. He called upon him also to withdraw the imputation that the pecuniary value of the slave was a motive for any such difference in the laws respecting them. He remarked that, by the laws of the Southern States, such a distinction is not made. I know, said he, no instance in which it exists. On the contrary, slaves are punished capitally for offences that are not so punished when committed by white men. In South Carolina, slaves have never been admitted to the benefit of clergy for offences at common law; and thus a slave is punished capitally for maiming or grievously beating a white man. Mr. Burt was also understood to say that there were “six or eight,” or “eight or ten,” offences in South Carolina for which slaves were punished capitally, but for which white men were not. MR. MANN replied that he had stated what he believed to be true; but if he had fallen into any mistake, he should be most happy to be corrected. He was assured also by the gentleman from Georgia, on his left, [Mr. TOOMBS,] that no such distinction existed as he had supposed; and it was but reasonable to believe that those gentlemen were more conversant with the southern laws than himself. MR. MANN added that he, (Mr. Mann,) could not be expected to have the statute books of the Southern States before him, at that time, to meet so unexpected a denial. Neither could he be expected by any honorable gentleman to make a retraction until he had time to see whether the ground he had taken were tenable. NOTE BY MR. MANN. On repairing to the Law library to ascertain which party was right in regard to the above difference of opinion, the second book I opened contained at least three cases, where the courts were authorized to sentence a slave to be transported for the commission of an offence, for which a white man must be unconditionally hung. See North Carolina Rev. Stat. vol. i. chap. 3, §§ 36, 37, 39. Of course, the reason of this difference is the pecuniary value of the slave. Hung, he would be worthless; transported to Cuba, he might bring five hundred dollars. The law was formerly so in Mr. Burt’s own state.
