Mr. SLOAN said he rose to observe, in a few words, that however afflicting it might be to contemplate a certain part of the creation used as articles of traffic, imported and exported the same as cattle, he did not consider the morality or immorality of the practice before the House. We must take the constitution as we find it, and as it is not in our power to prohibit the importation, the only question to be considered is, whether we shall most encourage the traffic, by letting the articles imported remain free of duty or by imposing a tax upon them. This view, he believed, presented to the mind the true question, and believing himself that a tax would, in some degree, discourage the importation, he should vote for the resolution. Mr. T. MOORE.--I am astonished to hear gentlemen, who advocate the resolution now under consideration, reprobate a traffic as horrid and infamous, and yet wish to draw a revenue from infamy, if it is an infamy. I differ very widely in opinion from the honorable gentleman from Pennsylvania, who thinks that a tax of ten dollars per head will operate as a check to the growth of this horrid traffic. If I thought it would have that effect I would cheerfully vote for the resolution. I believe a tax of ten dollars will not prevent the importation of a single person of this description. The gentleman told us that he hoped the General Government were disposed to discourage this traffic as far as they are authorized by the constitution. I hope this House will discourage this impolitic act of the Legislature of one of the Southern States--not by imposing a tax on those unfortunate people imported into the United States, but by passing a resolution expressive of its disapprobation of all acts permitting the importation of certain people into the United States. As the General Government cannot prohibit this traffic before the year 1808, I hope this House will reject the resolution under consideration, and totally disapprove every measure which attempts to draw revenue from an act that rivets the chains of slavery on any of the human race.
