clandestinely brought in and sold as slaves."[131] Plumer of New Hampshire stated that “of the unhappy beings, thus in violation of all laws transported to our shores, and thrown by force into the mass of our black population, scarcely one in a hundred is ever detected by the officers of the General Government, in a part of the country, where, if we are to believe the statement of Governor Rabun, ’an officer who would perform his duty, by attempting to enforce the law [against the slave trade] is, by many, considered as an officious meddler, and treated with derision and contempt;’ ...  I have been told by a gentleman, who has attended particularly to this subject, that ten thousand slaves were in one year smuggled into the United States; and that, even for the last year, we must count the number not by hundreds, but by thousands."[132] In 1821 a committee of Congress characterized prevailing methods as those “of the grossest fraud that could be practised to deceive the officers of government."[133] Another committee, in 1822, after a careful examination of the subject, declare that they “find it impossible to measure with precision the effect produced upon the American branch of the slave trade by the laws above mentioned, and the seizures under them.  They are unable to state, whether those American merchants, the American capital and seamen which heretofore aided in this traffic, have abandoned it altogether, or have sought shelter under the flags of other nations.”  They then state the suspicious circumstance that, with the disappearance of the American flag from the traffic, “the trade, notwithstanding, increases annually, under the flags of other nations.”  They complain of the spasmodic efforts of the executive.  They say that the first United States cruiser arrived on the African coast in March, 1820, and remained a “few weeks;” that since then four others had in two years made five visits in all; but “since the middle of last November, the commencement of the healthy season on that coast, no vessel has been, nor, as your committee is informed, is, under orders for that service."[134] The United States African agent, Ayres, reported in 1823:  “I was informed by an American officer who had been on the coast in 1820, that he had boarded 20 American vessels in one morning, lying in the port of Gallinas, and fitted for the reception of slaves.  It is a lamentable fact, that most of the harbours, between the Senegal and the line, were visited by an equal number of American vessels, and for the sole purpose of carrying away slaves.  Although for some years the coast had been occasionally visited by our cruizers, their short stay and seldom appearance had made but slight impression on those traders, rendered hardy by repetition of crime, and avaricious by excessive gain.  They were enabled by a regular system to gain intelligence of any cruizer being on the coast."[135]
