These voyages were generally made under the flag of a foreign nation, and often the vessel was sold in a foreign port to escape confiscation. South Carolina's own Congressman confessed that although the State had prohibited the trade since 1788, she "was unable to enforce" her laws. "With navigable rivers running into the heart of it," said he, "it was impossible, with our means, to prevent our Eastern brethren, who, in some parts of the Union, in defiance of the authority of the General Government, have been engaged in this trade, from introducing them into the country. The law was completely evaded, and, for the last year or two [1802-3], Africans were introduced into the country in numbers little short, I believe, of what they would have been had the trade been a legal one."[50] The same tale undoubtedly might have been told of Georgia. 51. ~The South Carolina Repeal of 1803.~ This vast and apparently irrepressible illicit traffic was one of three causes which led South Carolina, December 17, 1803, to throw aside all pretence and legalize her growing slave-trade; the other two causes were the growing certainty of total prohibition of the traffic in 1808, and the recent purchase of Louisiana by the United States, with its vast prospective demand for slave labor. Such a combination of advantages, which meant fortunes to planters and Charleston slave-merchants, could not longer be withheld from them; the prohibition was repealed, and the United States became again, for the first time in at least five years, a legal slave mart. This action shocked the nation, frightening Southern States with visions of an influx of untrained barbarians and servile insurrections, and arousing and intensifying the anti-slavery feeling of the North, which had long since come to think of the trade, so far as legal enactment went, as a thing of the past. Scarcely a month after this repeal, Bard of Pennsylvania solemnly addressed Congress on the matter. "For many reasons," said he, "this House must have been justly surprised by a recent measure of one of the Southern States. The impressions, however, which that measure gave my mind, were deep and painful. Had I been informed that some formidable foreign Power had invaded our country, I would not, I ought not, be more alarmed than on hearing that South Carolina had repealed her law prohibiting the importation of slaves.... Our hands are tied, and we are obliged to stand confounded, while we see the flood-gate opened, and pouring incalculable miseries into our country."[51] He then moved, as the utmost legal measure, a tax of ten dollars per head on slaves imported.
