Mr. Alderman Sawbridge immediately arose, and asked Mr. Wilberforce, if he meant to adduce any other evidence, besides that in the privy council report, in behalf of his propositions, or to admit other witnesses, if such could be found, to invalidate them. Mr. Wilberforce replied, that he was quite satisfied with the report on the table. It would establish all his propositions. He should call no witnesses himself: as to permission to others to call them, that must be determined by the house.

This question and this answer gave birth immediately to great disputes upon the subject. Aldermen Sawbridge, Newnham, and Watson; Lords Penrhyn and Maitland; Mr. Gascoyne, Marsham, and others spoke against the admission of the evidence, which had been laid upon the table. They contended, that it was insufficient, defective, and contradictory; that it was ex parte evidence; that it had been manufactured by ministers; that it was founded chiefly on hearsay, and that the greatest part of it was false; that it had undergone no cross-examination; that it was unconstitutional; and that, if they admitted it, they would establish a dangerous precedent, and abandon their rights. It was urged on the other hand by Mr. Courtenay, that it could not be ex parte evidence, because it contained testimony on both sides of the question. The circumstance also of its being contradictory, which had been alleged against it, proved that it was the result of an impartial examination. Mr. Fox observed, that it was perfectly admissible. He called upon those, who took the other side of the question, to say why, if it was really inadmissible, they had not opposed it at first. It had now been a long time on the table, and no fault had been found with it. The truth was, it did not suit them, and they were determined by a side-wind as it were to put an end to the inquiry. Mr. Pitt observed that, if parliament had previously resolved to receive no evidence on a given subject but from the privy council, such a resolution indeed would strike at the root of the privileges of the House of Commons; but it was absurd to suppose that the house could upon no occasion receive evidence, taken where it was most convenient to take it, and subject throughout to new investigation, if any one doubted its validity. The report of the privy council consisted, first, of calculations and accounts from the public offices, and, next, of written documents on the subject; both of which were just as authentic, as if they had been laid upon the table of that house. The remaining part of it consisted of the testimony of living witnesses, all of whose names were published, so that if any one doubted their veracity, it was open to him to reexamine all or each of them. It had been said by adversaries that the report on the table was a weak and imperfect report, but would not these have the advantage of its weakness and imperfection? It was strange, when his honourable friend, Mr. Wilberforce, had said, "Weak and imperfect as the report may be thought to be, I think it strong enough to bear me out in all my propositions," that they, who objected to it, should have no better reason to give than this, "We object, because the ground of evidence on which you rest is too weak to support your cause." Unless it were meant to say (and the meaning seemed to be but thinly disguised) that the house ought to abandon the inquiry, he saw no reason whatever for not going immediately into a committee; and he wished gentlemen to consider whether it became the dignity of their proceedings to obstruct the progress of an inquiry, which the house had pledged itself to undertake. Their conduct indeed seemed extraordinary on this occasion. It was certainly singular that, while the report had been five weeks upon the table, no argument had been brought against its sufficiency; but that on the moment when the house was expected to come to an ultimate vote upon the subject, it should be thought defective, contradictory, unconstitutional, and otherwise objectionable. These objections, he was satisfied, neither did nor could originate with the country gentlemen; but they were brought forward, for purposes not now to be concealed, by the avowed enemies of this noble cause.

In the course of the discussion, which arose upon this subject, every opportunity was taken to impress the house with the dreadful consequences of the abolition. Mr. Henniker read a long letter from the King of Dahomey to George the First; which had been found among the papers of James, first Duke of Chandos, and which had remained in the family till that time. In this, the King of Dahomey boasted of his victory over the King of Ardrah, and how he had ornamented the pavement and walls of his palace with the heads of the vanquished. These cruelties, Mr. Henniker said, were not imputable to the Slave-trade. They showed the Africans to be naturally a savage people, and that we did them a great kindness by taking them from their country. Alderman Sawbridge maintained that, if the abolition passed, the Africans, who could not be sold as slaves, would be butchered at home; while those, who had been carried to our islands, would be no longer under control. Hence insurrections, and the manifold evils which belonged to them. Alderman Newnham was certain that the abolition would be the ruin of the trade of the country. It would affect even the landed interest, and the funds. It would be impossible to collect money to diminish the national debt. Every man in the kingdom would feel the abolition come home to him. Alderman Watson maintained the same argument, and pronounced the trade under discussion to be a merciful and humane trade.

Compensation was also insisted upon by Mr. Drake, Alderman Newnham, Mr. Henniker, Mr. Cruger, and others. This was resisted by Mr. Burke; who said that compensation in such a case would be contrary to every principle of legislation. Government gave encouragement to any branch of commerce, while it was regarded as conducive to the welfare of the community, or compatible with humanity and justice. But they were competent to withdraw their countenance from it, when it was found to be immoral, and injurious, and disgraceful to the state. They, who engaged in it, knew the terms under which they were placed, and adopted it with all the risks with which it was accompanied; and of consequence it was but just, that they should be prepared to abide by the loss which might accrue, when the public should think it right no longer to support it. But such a trade as this it was impossible any longer to support. Indeed it was not a trade. It was a system of robbery. It was a system, too, injurious to the welfare of other nations.

How could Africa ever be civilized under it? While we continued to purchase the natives, they must remain in a state of barbarism. It was impossible to civilize slaves. It was contrary to the system of human nature. There was no country placed under such disadvantageous circumstances, into which the shadow of improvement had ever been introduced.

Great pains were taken to impress the house with the propriety of regulation. Sir Grey Cooper; Aldermen Sawbridge, Watson, and Newnham; Mr. Marsham, and Mr. Cruger, contended strenuously for it, instead of abolition. It was also stated that the merchants would consent to any regulation of the trade, which might be offered them.

In the course of the debate much warmth of temper was manifested on both sides. The expression of Mr. Fox in a former debate, "that the Slave-trade could not be regulated, because there could be no regulation of robbery and murder," was brought up, and construed by planters in the house as a charge of these crimes upon themselves. Mr. Fox, however, would not retract the expression. He repeated it. He had no notion, however, that any individual would have taken it to himself. If it contained any reflection at all, it was on the whole parliament, who had sanctioned such a trade. Mr. Molyneux rose up, and animadverted severely on the character of Mr. Ramsay, one of the evidences in the privy council report, during his residence in the West Indies. This called up Sir William Dolben and Sir Charles Middleton in his defence, the latter of whom bore honourable testimony to his virtues from an intimate acquaintance with him, and a residence in the same village with him, for twenty years. Mr. Molyneux spoke also in angry terms of the measure of abolition. To annihilate the trade, he said, and to make no compensation on account of it, was an act of swindling. Mr. Macnamara called the measure hypocritical, fanatic, and methodistical. Mr. Pitt was so irritated at the insidious attempt to set aside the privy council report, when no complaint had been alleged against it before, that he was quite off his guard, and he thought it right afterwards to apologize for the warmth into he had been betrayed. The Speaker too was obliged frequently to interfere. On this occasion no less than thirty members spoke. And there had probably been few seasons, when so much disorder had been discoverable in that house.

The result of the debate was, a permission to those interested in the continuance of the Slave-trade to bring counsel to the bar on the twenty-sixth of May, and then to introduce such witnesses, as might throw further light on the propositions in the shortest time: for Mr. Pitt only acquiesced in this new measure on a supposition, "that there would be no unnecessary delay, as he could, by no means submit to the ultimate procrastination of so important a business." He even hoped (and in this hope he was joined by Mr. Fox) that those concerned would endeavour to bring the whole of the evidence they meant to offer at the first examination.

On the day appointed, the house met for the purposes now specified; when Alderman Newnham, thinking that such an important question should not be decided but in a full assembly of the representatives of the nation, moved for a call of the house on that day fortnight. Mr. Wilberforce stated that he had no objection to such a measure; believing the greater the number present the more favourable it would be to his cause. This motion, however, produced a debate and a division, in which it appeared that there were one hundred and fifty-eight in favour of it, and twenty-eight against it. The business of the day now commenced. The house went into a committee, and Sir William Dolben was put into the chair. Mr. Serjeant Le Blanc was then called in. He made an able speech in behalf of his clients; and introduced John Barnes, esquire, as his first witness, whose examination took up the remainder of the day. By this step they, who were interested in the continuance of the trade, attained their wishes, for they had now got possession of the ground with their evidence; and they knew they could keep it, almost as long as they pleased, for the purposes of delay. Thus they, who boasted, when the privy council examinations began, that they would soon do away all the idle tales, which had been invented against them, and who desired the public only to suspend their judgment till the report should come out, when they would see the folly and wickedness of all our allegations, dared not abide by the evidence, which they themselves had taught others to look up to as the standard by which they were desirous of being judged: thus they, who had advantages beyond measure in forming a body of evidence in their own favour, abandoned that, which they had collected. And here it is impossible for me not to make a short comparative statement on this subject, if it were only to show how little can be made out, with the very best opportunities, against the cause of humanity and religion. With respect to ourselves, we had almost all our witnesses to seek. We had to travel after them for weeks together. When we found them, we had scarcely the power of choice. We were obliged to take them as they came. When we found them, too, we had generally to implore them to come forward in our behalf. Of those so implored three out of four refused, and the plea for this refusal was a fear lest they should injure their own interests. The merchants, on the other hand, had their witnesses ready on the spot. They had always ships in harbour containing persons, who had a knowledge of the subject. They had several also from whom to choose. If one man was favourable to their cause in three of the points belonging to it, but was unfavourable in the fourth, he could be put aside and replaced. When they had thus selected them, they had not to entreat, but to command, their attendance. They had no fear, again, when they thus commanded, of a refusal on the ground of interest; because these were promoting their interest by obliging those who employed them. Viewing these and other circumstances, which might be thrown into this comparative statement, it was some consolation to us to know, amidst the disappointment which this new measure occasioned, and our apparent defeat in the eyes of the public, that we had really beaten our opponents at their own weapons, and that, as this was a victory in our own private feelings, so it was the presage to us of a future triumph.

On the twenty-ninth of May, Mr. Tierney made a motion to divide the consideration of the Slave-trade into two heads, by separating the African from the West Indian part of the question. This he did for the more clear discussion of the propositions, as well as to save time. This motion, however, was overruled by Mr. Pitt.
