Amelia Island and the town of St. Mary's became notorious as two of the principal rendezvous of smugglers. A writer in "Niles' Register" in 1818 says that a regular chain of posts was established from the head of St. Mary's river to the upper country, and through the Indian nation by means of which slaves are hurried to every part of the country. The woodmen along the river side rode like so many Arabs loaded with slaves ready for market. When ready to form a caravan, an Indian alarm was created that the woods might be less frequented, and if pursued in Georgia they escaped to Florida.[43] Mr. M'Intosh, Collector of the Port of Darien, in a letter in 1818, says: "I am in possession of undoubted information that African and West Indian negroes are almost daily illicitly introduced into Georgia, for sale or settlement, or passing through it to the territories of the United States."[44] In 1817 it was reported to the Secretary of the Navy that "most of the goods carried to Galveston are introduced into the United States, the most bulky and least valuable regularly through the custom house; the most valuable and the slaves are smuggled in through the numerous inlets to the westward where the people are but too much disposed to render them every possible assistance. Several hundred slaves are now at Galveston."[45] "Niles' Register," in 1818, quoting from the "Democrat Press," has a very interesting account of how the law against the importation of slaves was evaded at New Orleans: An agent would be sent to the West Indies and even to Africa to purchase a cargo of slaves. On the return when the slave ship got near Balize the agent would leave her, go in haste to New Orleans and inform the proper authorities that a certain vessel had come into the Mississippi, said to be bound for New Orleans and having on board a certain number of negroes contrary to the law of the United States. The vessel and cargo would be libelled and the slaves sold at public auction. One half of the purchase money would go to the informer and the other to the United States.[46] The informer and agent was the same man and a partner in the transaction. This was a profitable business and about ten thousand slaves a year are said to have been thus introduced.[47] It is quite evident that the illicit slave trade at this time was very great. In 1819 Mr. Middleton, of South Carolina, said in Congress that in his opinion thirteen thousand Africans were annually smuggled into the United States, and Mr. Wright, of Virginia, estimated the number at fifteen thousand.[48] In 1818, 1819 and 1820 Congress passed acts to supplement and render more effective the act of 1807.[49] Du Bois says that for a decade after 1825 there appears little positive evidence of a large illicit importation, but thinks notwithstanding that slaves were largely imported.[50]
