"'Matters now began to look rather disheartening,--I mean as far as my grand object was concerned. There was but one other port left, and this was between two and three hundred miles distant. I determined, however, to go to Plymouth. I had already been more successful in this tour, with respect to obtaining general evidence, than in any other of the same length; and the probability was, that as I should continue to move among the same kind of people, my success would be in a similar proportion, according to the number visited. These were great encouragements to me to proceed. At length I arrived at the place of my last hope. On my first day's expedition I boarded forty vessels, but found no one in these who had been on the coast of Africa in the slave-trade. One or two had been there in king's ships; but they never had been on shore. Things were now drawing near to a close; and notwithstanding my success, as to general evidence, in this journey, my heart began to beat. I was restless and uneasy during the night. The next morning I felt agitated again between the alternate pressure of hope and fear; and in this state I entered my boat. The fifty-seventh vessel I boarded was the Melampus frigate.--One person belonging to it, on examining him in the captain's cabin, said he had been two voyages to Africa; and I had not long discoursed with him, before I found, to my inexpressible joy, that he was the man. I found, too, that he unravelled the question in dispute precisely as our inferences had determined it. He had been two expeditions up the river Calabar, in the canoes of the natives. In the first of these they came within a certain distance of a village: they then concealed themselves under the bushes, which hung over the water from the banks. In this position they remained during the day-light; but at night they went up to it armed, and seized all the inhabitants who had not time to make their escape. They obtained forty-five persons in this manner. In the second, they were out eight or nine days, when they made a similar attempt, and with nearly similar success. They seized men, women, and children, as they could find them in the huts. They then bound their arms, and drove them before them to the canoes. The name of the person thus discovered on board of the Melampus was Isaac Parker. On inquiring into his character, from the master of the division, I found it highly respectable. I found also afterward that he had sailed with Captain Cook, with great credit to himself, round the world. It was also remarkable, that my brother, on seeing him in London, when he went to deliver his evidence, recognized him as having served on board the Monarch, man-of-war, and as one of the most exemplary men in that ship.'
