On going one day by the Exchange after this interview with Gardiner, I overheard a young gentleman say to another, "that it happened on the Coast last year, and that he saw it." I wished to know who he was, and to get at him if I could. I watched him at a distance for more than half an hour, when I saw him leave his companion. I followed him till he entered a house. I then considered whether it would be proper, and in what manner, to address him when he should come out of it. But I waited three hours, and I never saw him. I then concluded that he either lodged where I saw him enter, or that he had gone to dine with some friend. I therefore took notice of the house, and, showing it afterwards to several of my friends, desired them to make him out for me. In a day or two I had an interview with him. His name was James Arnold. He had been two voyages to the coast of Africa for slaves; one as surgeon's mate in the Alexander, in the year 1785, and the other as surgeon in the Little Pearl, in the year 1786, from which he had not then very long returned. I asked him if he was willing to give me any account of these voyages, for that I was making an inquiry into the nature of the Slave-trade. He replied, he knew that I was. He had been cautioned about falling-in with me. He had, however, taken no pains to avoid me. It was a bad trade, and ought to be exposed. I went over the same ground as I had gone with Gardiner relative to the first of these voyages, or that in the Alexander. It is not necessary to detail the particulars. It is impossible, however, not to mention, that the treatment of the seamen on board this vessel was worse than I had ever before heard of. No less than eleven of them, unable to bear their lives, had deserted at Bonny on the coast of Africa,--which is a most unusual thing,--choosing all that could be endured, though in a most inhospitable climate, and in the power of the natives, rather than to continue in their own ship. Nine others also, in addition to the loss of these, had died in the same voyage. As to the rest, he believed, without any exception, that they had been badly used. In examining him with respect to his second voyage, or that in the Little Pearl, two circumstances came out with respect to the slaves, which I shall relate in few words. The chief mate used to beat the men-slaves on very trifling occasions. About eleven one evening, the ship then lying off the coast, he heard a noise in their room. He jumped down among them with a lanthorn in his hand. Two of those, who had been ill-used by him, forced themselves out of their irons and, seizing him, struck him with the bolt of them, and it was with some difficulty that he was extricated from them by the crew.
