HOUSE OF REPRESENTATIVES, FEBRUARY 12, 1790
MR. GERRY thought the interference of Congress fully compatible with the Constitution, and could not help lamenting the miseries to which the natives of Africa were exposed by this inhuman commerce. He never contemplated the subject without reflecting what his own feelings would be, in case himself, his children, or friends were placed in the same deplorable circumstances. He then adverted to the flagrant acts of cruelty which are committed in carrying on that traffic; and asked whether it can be supposed that Congress has no power to prevent such abuses? Congress can, agreeably to the Constitution, lay a duty of ten dollars on imported slaves; they may do this immediately. He made a calculation of the value of the slaves in the Southern States, and supposed they may be worth ten millions of dollars. Congress have a right, if they see proper, to make a proposal to the Southern States to purchase the whole of them, and their resources in the Western Territory might furnish them with the means. He did not intend to suggest a measure of this kind; he only instanced these particulars to show that Congress certainly has a right to intermeddle in the business.
