I had but just arrived in England, when Mr. Wilberforce made a new motion in the House of Commons on the subject of the Slave Trade. In referring to the transactions of the last session, he found that twenty-eight days had been allotted to the hearing of witnesses against the abolition, and that eleven persons only had been examined in that time. If the examinations were to go on in the same manner, they might be made to last for years. He resolved, therefore, to move, that, instead of hearing evidence in future in the house at large, members should hear it in an open committee above stairs; which committee should sit notwithstanding any adjournment of the house itself. This motion he made; and in doing it he took an opportunity of correcting an erroneous report; which was, that he had changed his mind on this great subject. This was, he said, so far from being the case, that the more he contemplated the trade, the more enormous he found it, and the more he felt himself compelled to persevere in endeavours for its abolition.

One would have thought that a motion, so reasonable and so constitutional, would have met with the approbation of all; but it was vehemently opposed by Mr. Gascoyne, Alderman Newnham, and others. The plea set up was, that there was no precedent for referring a question of such importance to a committee. It was now obvious, that the real object of our opponents in abandoning decision by the privy council evidence was delay. Unable to meet us there, they were glad to fly to any measure, which should enable them to put off the evil day. This charge was fixed upon them in unequivocal language by Mr. Fox; who observed besides, that if the members of the house should then resolve to hear evidence in a committee of the whole house as before, it would amount to a resolution, that the question of the abolition of the Slave Trade should be put by, or at least that it should never be decided by them. After a long debate, the motion of Mr. Wilberforce was voted without a division; and the examination of witnesses proceeded in behalf of those who were interested in the continuance of the trade.

This measure having been resolved upon, by which despatch in the examinations was promoted, I was alarmed lest we should be called upon for our own evidence, before we were fully prepared. The time which I had originally allotted for the discovery of new witnesses, had been taken up, if not wasted, in France. In looking over the names of the sixteen, who were to have been examined by the committee of privy council, if there had been time, one had died, and eight, who were sea-faring people, were out of the kingdom. It was time, therefore, to stir immediately in this business. Happily, on looking over my letters, which I found on my arrival in England, the names of several had been handed to me, with the places of their abode, who could give me information on the subject of our question. All these I visited with the utmost despatch. I was absent only three weeks. I had travelled a thousand miles in this time, had conversed with seventeen persons, and had prevailed upon three to be examined.

I had scarcely returned with the addition of these witnesses to my list, when I found it necessary to go out again upon the same errand. This second journey arose in part from the following circumstances. There was a matter in dispute relative to the mode of obtaining slaves in the rivers of Calabar and Bonny. It was usual, when the slave-ships lay there, for a number of canoes to go into the inland country. These went in a fleet. There might be from thirty to forty armed natives in each of them. Every canoe, also, had a four or a six-pounder (cannon) fastened to her bow. Equipped in this manner they departed; and they were usually absent from eight to fourteen days. It was said that they went to fairs, which were held on the banks of these rivers, and at which there was a regular show of slaves. On their return they usually brought down from eight hundred to a thousand of these for the ships. These lay at the bottom of the canoes; their arms and legs having been first bound by the ropes of the country. Now the question was, how the people, thus going up these rivers, obtained their slaves?

It was certainly a very suspicious circumstance, that such a number of persons should go out upon these occasions; and that they should be armed in such a manner. We presumed, therefore, that, though they might buy many of the slaves, whom they brought down, at the fairs which have been mentioned, they obtained others by violence, as opportunity offered. This inference we pressed upon our opponents, and called upon them to show what circumstances made such warlike preparations necessary on these excursions. To this they replied readily, "The people in the canoes," said they, "pass through the territories of different petty princes; to each of whom, on entering his territory, they pay a tribute or toll. This tribute has been long fixed; but attempts frequently have been made to raise it. They who follow the trade cannot afford to submit to these unreasonable demands; and therefore they arm themselves in case of any determination on the part of these petty princes to enforce them." This answer we never judged to be satisfactory. We tried therefore, to throw light upon the subject, by inquiring if the natives who went upon these expeditions usually took with them as many goods as would amount to the number of the slaves they were accustomed to bring back with them. But we could get no direct answer, from any actual knowledge, to this question. All had seen the canoes go out and return; but no one had seen them loaded, or had been on board them. It appeared, however, from circumstantial evidence, that though the natives on these occasions might take some articles of trade with them, it was impossible from appearances that they could take them in the proportion mentioned. We maintained, then, our inference as before; but it was still uniformly denied.

How then were we to decide this important question? for it was said that no white man was ever permitted by the natives to go up in these canoes. On mentioning accidentally the circumstances of the case, as I have now stated them, to a friend, immediately on my return from my last journey, he informed me that he himself had been in company, about a year before, with a sailor, a very respectable-looking man, who had been up these rivers. He had spent half an hour with him at an inn. He described his person to me; but he knew nothing of his name, or of the place of his abode. All he knew was, that he was either going, or that he belonged to, some ship of war in ordinary; but he could not tell at what port. I might depend upon all these circumstances if the man had not deceived him; and he saw no reason why he should.

I felt myself set on fire, as it were, by this intelligence, deficient as it was; and I seemed to determine instantly that I would, if it were possible, find him out. For if our suspicions were true that the natives frequently were kidnapped in these expeditions, it would be of great importance to the cause of the abolition to have them confirmed; for as many slaves came annually from these two rivers, as from all the coast of Africa besides. But how to proceed on so blind an errand was the question. I first thought of trying to trace the man by letter; but this might be tedious. The examinations were now going on rapidly. We should soon be called upon for evidence ourselves; besides, I knew nothing of his name. I then thought it to be a more effectual way to apply to Sir Charles Middleton, as comptroller of the navy, by whose permission I could board every ship of war in ordinary in England, and judge for myself. But here the undertaking seemed very arduous, and the time it would consume became an objection in this respect, that I thought I could not easily forgive myself, if I were to fail in it. My inclination, however, preponderated this way. At length I determined to follow it; for, on deliberate consideration, I found that I could not employ my time more advantageously to the cause; for as other witnesses must be found out somewhere, it was highly probable that, if I should fail in the discovery of this man, I should, by moving among such a number of sea-faring people, find others who could give their testimony in our favour.

I must now inform the reader, that ships of war in ordinary, in one of which this man was reported to be, are those which are out of commission, and which are laid up in the different rivers and waters in the neighbourhood of the king's dock-yards. Every one of these has a boatswain, gunner, carpenter, and assistants on board. They lie usually in divisions of ten or twelve; and a master in the navy has a command over every division.

At length I began my journey. I boarded all the ships of war lying in ordinary at Deptford, and examined the different persons in each. From Deptford I proceeded to Woolwich, where I did the same. Thence I hastened to Chatham, and then, down the Medway, to Sheerness. I had now boarded above a hundred and sixty vessels of war. I had found out two good and willing evidences among them; but I could gain no intelligence of him who was the object of my search.

From Chatham I made the best of my way to Portsmouth harbour. A very formidable task presented itself here; but the masters' boats were ready for me, and I continued my pursuit. On boarding the Pegase, on the second day, I discovered a very respectable person in the gunner of that ship. His name was George Millar. He had been on board the Canterbury slaveship at the dreadful massacre at Calabar. He was the only disinterested evidence living, of whom I had yet heard. He expressed his willingness to give, his testimony, if his presence should be thought necessary in London. I then continued my pursuit for the remainder of the day. On the next day I resumed and finished it for this quarter. I had now examined the different persons in more than a hundred vessels in this harbour, but I had not discovered the person I had gone to seek.
