The House again resolved itself into a Committee of the Whole on the Impost Bill, Mr. PAGE in the chair. AFRICAN SLAVES. Mr. PARKER moved to insert a clause in the bill, imposing a duty on the importation of slaves, of ten dollars each person. He was sorry that the constitution prevented Congress from prohibiting the importation altogether; he thought it a defect in that instrument that it allowed of such a practice; it was contrary to the Revolution principles, and ought not to be permitted; but as he could not do all the good he desired, he was willing to do what lay in his power. He hoped such a duty as he moved for would prevent, in some degree, this irrational and inhuman traffic; if so, he should feel happy from the success of his motion. Mr. SMITH, of South Carolina, hoped that such an important and serious proposition as this would not be hastily adopted. It was a very late moment for the introduction of new subjects. He expected the committee had got through the business, and would rise without discussing any thing further. At least, if gentlemen were determined on considering the present motion, he hoped they would delay it for a few days, in order to give time for an examination of the subject. It was certainly a matter big with the most serious consequences to the State he represented; he did not think any one thing that had been discussed was so important to them, and the welfare of the Union, as the question now brought forward; but he was not prepared to enter on any argument, and therefore requested the motion might either be withdrawn or laid on the table. Mr. SHERMAN approved of the object of the motion, but he did not think this bill was proper to embrace the subject. He could not reconcile himself to the insertion of human beings as an article of duty, among goods, wares, and merchandise. He hoped it would be withdrawn for the present, and taken up hereafter as an independent subject. Mr. JACKSON, observing the quarter from which this motion came, said it did not surprise him, though it might have that effect upon others. He recollected that Virginia was an old settled State, and had her complement of slaves; so she was careless of recruiting her numbers by this means; the natural increase of her imported blacks was sufficient for their purpose; but he thought gentlemen ought to let their neighbors get supplied, before they imposed such a burthen upon the importation. He knew this business was viewed in an odious light to the eastward, because the people were capable of doing their own work, and had no occasion for slaves; but gentlemen will have some feeling for others; they will not try to throw all the weight upon those who have assisted in lightening their burthens; they do not wish to charge us for every comfort and enjoyment of life, and at the same time take away the means of procuring them; they do not wish to break us down at once.
