RENEWAL OF PIRACY AND THE SLAVE-TRADE AT THE CLOSE OF THE EUROPEAN WAR--BRITISH SQUADRON--TREATIES WITH THE NATIVES--ORIGIN OF BARRACOONS--USE OF THE AMERICAN FLAG IN THE SLAVE-TRADE--OFFICIAL CORRESPONDENCE ON THE SUBJECT--CONDITION OF SLAVES ON BOARD OF THE SLAVE-VESSELS--CASE OF THE VELOZ PASSAGEIRA--FRENCH SQUADRON. It was the cessation of the last great European war, which assembled the matured villany of the world on the African coast to re-establish the slave-trade. This traffic had been suspended during the latter years of the contest, as England and the United States had abolished it, and the former was strong enough at sea to prevent other European powers from engaging in it. In fact, she had swept almost the whole European marine from the ocean. The treaties formed at the peace, left Europe to the strife between anarchy and despotism; and gave up the coast of Africa to the slave-trade and piracy. Every evil and every fear which have harassed the world since that time, seem to be the retributions of an indignant Providence. Let it not be imagined that these dealings of justice with men are at an end. What could atone for giving up the coasts of a whole continent to be ravaged by the slave-ships of France, Spain, and Portugal? What compensation for this vicious and deadly scourge has Africa yet received? The cruising, suffering, sickness, deaths and expenses of nearly half a century have not remedied the crime of signing these treaties. The ambassador, minister, or whoever he was, that signed them, bears a load of guilt, such as few mortal men have assumed. England set about remedying this in a more commendable spirit, as soon as the years of free and unrestricted crime, which she had really granted to these nations, were run out. During about twenty years subsequently, when treaties with these powers had granted mutual right of search and capture, three hundred vessels were seized, having slaves on board. But during the latter part of this period, more than one hundred thousand half-dead negroes were annually landed from slave-vessels in Cuba and Brazil.
