The colony which had been partly projected to receive slaves captured by United States vessels, for the present, at least, proving a failure, Captain Trenchard requested the governor of Sierra Leone to receive such slaves as should hereafter be liberated by Americans. The governor acceded, and the _Cyane_ turned her prow homeward October 4, and after a fifty-seven days’ experience of constant squalls and calms, until December 1, arrived at New York on Christmas day. Emerging from tropical Africa, even the intermediate ocean voyage did not prepare the men for the severe weather of our latitude, and catarrhs and fevers broke out. The ship, too, was full of cases of chronic sickness. Between disease and the elements, the condition of the crew was deplorable. In this, his first African cruise, Perry, as usual, profited richly by experience. He had made a systematic study of the climate, coast, and ship-hygiene. He believed, and expressed his conviction, that for much of the preventible sickness some one was responsible. Though, thereby, he lost the good will of certain persons, Lieutenant Perry rendered unquestionable benefits to later ships on the African station. During the next year, the U. S. S. _Nautilus_, with two agents of the government, and two of the colonization societies, sailed with a fresh lot of colonists for Africa. Thus the slow work of building up the first and only American colony recognized by the United States went on. There were some far-seeing spirits on both sides of Mason and Dixon’s line, who had begun to see that the only real cure for the African slave-trade, on the west coast of Africa, was its abolition in America. The right way for the present, however, was to carry the war into Africa by planting free colonies. CHAPTER VII. PERRY LOCATES THE SITE OF MONROVIA. ON the 5th of July 1821, Perry was doubly happy, in his first sole command of a man-of-war, and in her being bound upon a worthy mission. The _Shark_ was to convey Dr. Eli Ayres to Africa as agent of the United States in Liberia. He was especially glad that he could now enforce his ideas of ship hygiene. His ambition was to make the cruise without one case of fever or scurvy. The _Shark_ sped directly through the Canaries. Here, the human falcons resorted before swooping on their human prey. At Cape de Verde, he found the villianous slave-trade carried on under the mask of religion. Thousands of negroes decoyed or kidnapped from Africa, were lodged at the trading station for one year, and then baptized by the wholesale in the established Roman faith. They were then shipped to Brazil as Portuguese “subjects.” It was first aspersion, and then dispersion.
