52. ~The Louisiana Slave-Trade, 1803-1805.~ About this time the cession of Louisiana brought before Congress the question of the status of slavery and the slave-trade in the Territories. Twice or thrice before had the subject called for attention. The first time was in the Congress of the Confederation, when, by the Ordinance of 1787,[55] both slavery and the slave-trade were excluded from the Northwest Territory. In 1790 Congress had accepted the cession of North Carolina back lands on the express condition that slavery there be undisturbed.[56] Nothing had been said as to slavery in the South Carolina cession (1787),[57] but it was tacitly understood that the provision of the Northwest Ordinance would not be applied. In 1798 the bill introduced for the cession of Mississippi contained a specific declaration that the anti-slavery clause of 1787 should not be included.[58] The bill passed the Senate, but caused long and excited debate in the House.[59] It was argued, on the one hand, that the case in Mississippi was different from that in the Northwest Territory, because slavery was a legal institution in all the surrounding country, and to prohibit the institution was virtually to prohibit the settling of the country. On the other hand, Gallatin declared that if this amendment should not obtain, "he knew not how slaves could be prevented from being introduced by way of New Orleans, by persons who are not citizens of the United States." It was moved to strike out the excepting clause; but the motion received only twelve votes,--an apparent indication that Congress either did not appreciate the great precedent it was establishing, or was reprehensibly careless. Harper of South Carolina then succeeded in building up the Charleston slave-trade interest by a section forbidding the slave traffic from "without the limits of the United States." Thatcher moved to strike out the last clause of this amendment, and thus to prohibit the interstate trade, but he failed to get a second.[60] Thus the act passed, punishing the introduction of slaves from without the country by a fine of $300 for each slave, and freeing the slave.[61]
