At length the 12th of May arrived. Mr. Wilberforce rose up in the Commons and moved the order of the day for the house to resolve itself into a committee of the whole house, to take into consideration the petitions which had been presented against the Slave Trade.

This order having been read, he moved that the report of the committee of privy council, that the acts passed in the islands relative to slaves, that the evidence adduced last year on the Slave Trade, that the petitions offered in the last session against the Slave Trade, and that the accounts presented to the house in the last and present session relative to the exports and imports of Africa, be referred to the same committee.

These motions having been severally agreed to, the House immediately resolved itself into a committee of the whole house, and Sir William Dolben was put into the chair.

Mr. Wilberforce began by declaring, that when he considered how much discussion the subject, which he was about to explain to the committee, had occasioned, not only in that House, but throughout the kingdom, and throughout Europe; and when he considered the extent and importance of it, the variety of interests involved in it, and the consequences which might arise, he owned he had been filled with apprehensions, lest a subject of such magnitude, and a cause of such weight, should suffer from the weakness of its advocate; but when he recollected that, in the progress of his inquiries, he had everywhere been received with candour, that most people gave him credit for the purity of his motives, and that, however many of these might then differ from him, they were all likely to agree in the end, he had dismissed his fears, and marched forward with a firmer step in this cause of humanity, justice, and religion. He could not, however, but lament that the subject had excited so much warmth. He feared that too many on this account were but ill prepared to consider it with impartiality. He entreated all such to endeavour to be calm and composed. A fair and cool discussion was essentially necessary. The motion he meant to offer, was as reconcilable to political expediency as to national humanity. It belonged to no party question. It would in the end be found serviceable to all parties, and to the best interests of the country. He did not come forward to accuse the West India planter, or the Liverpool merchant, or indeed any one concerned in this traffic; but, if blame attached anywhere, to take shame to himself in common, indeed, with the whole parliament of Great Britain, who, having suffered it to be carried on under their own authority, were all of them participators in the guilt.

In endeavouring to explain the great business of the day, he said he should call the attention of the House only to the leading features of the Slave Trade. Nor should he dwell long upon these. Every one might imagine for himself what must be the natural consequence of such a commerce with Africa. Was it not plain that she must suffer from it? that her savage manners must be rendered still more ferocious? and that a trade of this nature, carried on round her coasts, must extend violence and desolation to her very centre? It was well known that the natives of Africa were sold as goods, and that numbers of them were continually conveyed away from their country by the owners of British vessels. The question then was, which way the latter came by them. In answer to this question, the privy council report, which was then on the table, afforded evidence the most satisfactory and conclusive. He had found things in it, which had confirmed every proposition he had maintained before, whether this proposition had been gathered from living information of the best authority, or from the histories he had read. But it was unnecessary either to quote the report, or to appeal to history on this occasion. Plain reason and common sense would point out how the poor Africans were obtained. Africa was a country divided into many kingdoms, which had different governments and laws. In many parts the princes were despotic. In others they had a limited rule. But in all of them, whatever the nature of the government was, men were considered as goods and property, and, as such, subject to plunder in the same manner as property in other countries. The persons in power there were naturally fond of our commodities; and to obtain them, (which could only be done by the sale of their countrymen,) they waged war on one another, or even ravaged their own country, when they could find no pretence for quarrelling with their neighbours: in their courts of law many poor wretches, who were innocent, were condemned; and to obtain these commodities in greater abundance, thousands were kidnapped and torn from their families, and sent into slavery. Such transactions, he said, were recorded in every history of Africa, and the report on the table confirmed them. With respect, however, to these he should make but one or two observations. If we looked into the reign of Henry the Eighth, we should find a parallel for one of them. We should find that similar convictions took place; and that penalties followed conviction. With respect to wars, the kings of Africa were never induced to engage in them by public principles, by national glory, and least of all by the love of their people. This had been stated by those most conversant in the subject, by Dr. Spaarman and Mr. Wadstrom. They had conversed with these princes, and had learned from their own mouths that to procure slaves was the object of their hostilities. Indeed, there was scarcely a single person examined before the privy council who did not prove that the Slave Trade was the source of the tragedies acted upon that extensive continent. Some had endeavoured to palliate this circumstance; but there was not one who did not more or less admit it to be true. By one the Slave Trade was called the concurrent cause, by the majority it was acknowledged to be the principal motive, of the African wars. The same might be said with respect to those instances of treachery and injustice, in which individuals were concerned. And here he was sorry to observe that our own countrymen were often guilty. He would only at present advert to the tragedy at Calabar, where two-large African villages, having been for some time at war, made peace. This peace was to have, been ratified by intermarriages; but some of our captains, who were there, seeing their trade would be stopped for a while, sowed dissension again between them. They actually set one village against the other, took a share in the contest, massacred many of the inhabitants, and carried others of them away as slaves. But shocking as this transaction might appear, there was not a single history of Africa to be read, in which scenes of as atrocious a nature were not related. They, he said, who defended this trade, were warped and blinded by their own interests, and would not be convinced of the miseries they were daily heaping on their fellow creatures. By the countenance, they gave it, they had reduced the inhabitants of Africa to a worse state than that of the most barbarous nation. They had destroyed what ought to have been the bond of union and safety among them; they had introduced discord and anarchy among them; they had set kings against their subjects, and subjects against each other; they had rendered every private family wretched; they had, in short, given birth to scenes of injustice and misery not to be found in any other quarter of the globe.

Having said thus much on the subject of procuring slaves in, Africa, he would now go to that of the transportation of them. And here he had fondly hoped, that when men with affections and feelings like our own had been torn from their country, and everything dear to them, he should have found some mitigation of their sufferings; but the sad reverse was the case. This was the most wretched part of the whole subject. He was incapable, of impressing the House with what he felt upon it. A description of their conveyance was impossible. So much misery condensed, in so little room was more than the human imagination had ever before conceived. Think only of six hundred persons linked together, trying to get rid of each other, crammed in a close vessel with every object that was nauseous and disgusting, diseased, and struggling with all the varieties of wretchedness. It seemed impossible to add anything more to human misery. Yet shocking as this description must be felt to be by every man, the transportation had been described by several witnesses from Liverpool to be a comfortable conveyance. Mr. Norris had painted the accommodations on board a slave-ship in the most glowing colours. He had represented them in a manner which would have exceeded his attempts at praise of the most luxurious scenes. Their apartments, he said, were fitted up as advantageously for them as circumstances could possibly admit: they had several meals a day; some of their own country provisions, with the best sauces of African cookery; and, by way of variety, another meal of pulse, according to the European taste. After breakfast they had water to wash themselves, while their apartments were perfumed with frankincense and lime-juice. Before dinner they were amused after the manner of their country; instruments of music were introduced; the song and the dance were promoted; games of chance were furnished them; the men played and sang, while the women and girls made fanciful ornaments from beads, with which they were plentifully supplied. They were indulged in all their little fancies, and kept in sprightly humour. Another of them had said, when the sailors were flogged, it was out of the hearing of the Africans, lest it should depress their spirits. He by no means wished to say that such descriptions were wilful misrepresentations. If they were not, it proved that interest or prejudice was capable of spreading a film over the eyes thick enough to occasion total blindness.

Others, however, and these men of the greatest veracity, had given a different account. What would the house think, when by the concurring testimony of these the true history was laid open? The slaves who had been described as rejoicing in their captivity, were so wrung with misery at leaving their country, that it was the constant practice to set sail in the night, lest they should know the moment of their departure. With respect to their accommodation, the right ancle of one was fastened to the left ancle of another by an iron fetter; and if they were turbulent, by another on the wrists. Instead of the apartments described, they were placed in niches, and along the decks, in such a manner, that it was impossible for any one to pass among them, however careful he might be, without treading upon them. Sir George Yonge had testified, that in a slave-ship, on board of which he went, and which had not completed her cargo by two hundred and fifty, instead of the scent of frankincense being perceptible to the nostrils, the stench was intolerable. The allowance of water was, so deficient, that the slaves were, frequently found gasping for life, and almost suffocated. The pulse with which they had been said to be favoured, were absolutely English horse-beans. The legislature of Jamaica had stated the scantiness both of water and provisions, as a subject which called for the interference of parliament. As Mr. Norris had said, the song and the dance were promoted, he could not pass over these expressions without telling the house what they meant. It would have been much more fair if he himself had explained the word promoted. The truth was, that, for the sake of exercise, these miserable wretches, loaded with chains and oppressed with disease, were forced to dance by the terror of the lash, and sometimes by the actual use of it. "I" said one of the evidences, "was employed to dance the men, while another person danced the women." Such then was the meaning of the, word promoted; and it might also be observed with respect to food, that instruments were sometimes carried out in order to force them to eat; which was the same sort of proof, how much they enjoyed themselves in this instance also. With respect to their singing, it consisted of songs, of lamentation for the loss of their country. While they sung they were in tears: so that one of the captains, more humane probably than the rest, threatened a woman with a flogging because the mournfulness of her song was too painful for his feelings. Perhaps he could not give a better proof of the sufferings of these injured people during their passage, than by stating the mortality which accompanied it. This was a species of evidence, which was infallible on this occasion. Death was a witness which could not deceive them; and the proportion of deaths would not only confirm, but, if possible, even aggravate our suspicion of the misery of the transit. It would be found, upon an average of all the ships, upon which evidence had been given, that, exclusively of such as perished before they sailed from Africa, not less than twelve and-a-half per cent died on their passage: besides these, the Jamaica report stated that four and-a-half per cent died while in the harbours, or on shore before the day of sale, which was only about the space of twelve or fourteen days after their arrival there; and one-third more died in the seasoning: and this in a climate exactly similar to their own, and where, as some of the witnesses pretended, they were healthy and happy. Thus out of every lot of one hundred shipped from Africa, seventeen died in about nine weeks, and not more than fifty lived to become effective labourers in our islands.

Having advanced thus far in his investigation, he felt, he said, the wickedness of the Slave Trade to be so enormous, so dreadful, and irremediable, that he could stop at no alternative short of its abolition, A trade founded on iniquity, and carried on with such circumstances of horror, must be abolished, let the policy of it be what it might; and he had from this time determined, whatever were the consequences, that he would never rest till he had effected that abolition. His mind had, indeed, been harassed by the objections of the West India planters, who had asserted, that the ruin of their property must be the consequence of such a measure. He could not help, however, distrusting their arguments. He could not believe that the Almighty Being, who had forbidden the practice of rapine and bloodshed, had made rapine and bloodshed necessary to any part of his universe. He felt a confidence in this persuasion, and took the resolution to act upon it. Light, indeed, soon broke in upon him. The suspicion of his mind was every day confirmed by increasing information, and the evidence he had now to offer upon this point was decisive and complete. The principle upon which he founded the necessity of the abolition was not policy, but justice: but though justice were the principle of the measure, yet he trusted he should distinctly prove it to be reconcilable with our truest political interest.

In the first place, he asserted that the number of the slaves in our West India islands might be kept up without the introduction of recruits from Africa; and to prove this, he would enumerate the different sources of their mortality. The first was the disproportion of the sexes, there being, upon an average, about five males imported to three females: but this evil, when the Slave Trade was abolished, would cure itself. The second consisted in the bad condition in which they were brought to the islands, and the methods of preparing them for sale. They arrived frequently in a sickly and disordered state, and then they were made up for the market by the application of astringents, washes, mercurial ointments, and repelling drugs, so that their wounds and diseases might be hid. These artifices were not only fraudulent but fatal; but these, it was obvious, would of themselves fall with the trade. A third was, excessive labour joined with improper food; and a fourth was, the extreme dissoluteness of their manners. These, also, would both of them be counteracted by the impossibility of getting further supplies: for owners, now unable to replace those slaves whom they might lose, by speedy purchases in the markets, would be more careful how they treated them in future, and a better treatment would be productive of better morals. And here he would just advert to an argument used against those who complained of cruelty in our islands, which was, that it was the interest of masters to treat their slaves with humanity: but surely it was immediate and present, not future and distant interest, which was the great spring of action in the affairs of mankind. Why did we make laws to punish men? It was their interest to be upright and virtuous: but there was a present impulse continually breaking in upon their better judgment, and an impulse, which was known to be contrary to their permanent advantage. It was ridiculous to say that men would be bound by their interest, when gain or ardent passion urged them. It might as well be asserted, that a stone could not be thrown into the air, or a body move from place to place, because the principle of gravitation bound them to the surface of the earth. If a planter in the West Indies found himself reduced in his profits, he did not usually dispose of any part of his slaves; and his own gratifications were never given up, so long as there was a possibility of making any retrenchment in the allowance of his slaves.—But to return to the subject which he had left: he was happy to state, that as all the causes of the decrease which he had stated might be remedied, so, by the progress of light and reformation, these remedies had been gradually coming into practice; and that, as these had increased, the decrease of slaves had in an equal proportion been lessened. By the gradual adoption of these remedies, he could prove from the report on the table, that the decrease of slaves in Jamaica had lessened to such a degree, that from the year 1774 to the present it was not quite one in a hundred, and that, in fact, they were at present in a state of increase; for that the births in that island, at this moment, exceeded the deaths by one thousand or eleven hundred per annum. Barbados, Nevis, Antigua, and the Bermudas, were, like Jamaica, lessening their decrease, and holding forth an evident and reasonable expectation of a speedy state of increase by natural population. But allowing the number of Negroes even to decrease for a time, there were methods which would insure the welfare of the West India islands. The lands there might be cultivated by fewer hands, and this to greater advantage to the proprietors and to this country, by the produce of cinnamon, coffee, and cotton, than by that of sugar. The produce of the plantations might also be considerably increased, even in the case of sugar, with less hands than were at present employed, if the owners of them would but introduce machines of husbandry. Mr. Long himself, long resident as a planter, had proved, upon his own estate, that the plough, though so little used in the West Indies, did the service of a hundred slaves, and caused the same ground to produce three hogsheads of sugar, which, when cultivated by slaves, would only produce two. The division of work, which, in free and civilized countries, was the grand source of wealth, and the reduction of the number of domestic servants, of whom not less than from twenty to forty were kept in ordinary families, afforded other resources for this purpose. But, granting that all these suppositions should be unfounded, and that everyone of these substitutes should fail for a time, the planters would be indemnified, as is the case in all transactions of commerce, by the increased price of their produce in the British market. Thus, by contending against the abolition, they were defeated in every part of the argument. But he would never give up the point, that the number of the slaves could be kept up, by natural population, and without any dependence whatever on the Slave Trade. He therefore called upon the house again to abolish it as a criminal waste of life—it was utterly unnecessary—he had proved it so by documents contained in the report. The merchants of Liverpool, indeed, had thought otherwise, but he should be cautious how he assented to their opinions. They declared last year that it was a losing trade at two slaves to a ton, and yet they pursued it when restricted to five slaves to three tons. He believed, however, that it was upon the whole a losing concern; in the same manner as the lottery would be a losing adventure to any company who should buy all the tickets. Here and there an individual gained a large prize, but the majority of adventurers gained nothing. The same merchants, too, had asserted, that the town of Liverpool would be mined by the abolition. But Liverpool did not depend for its consequence upon the Slave Trade. The whole export-tonnage from that place amounted to no less than 170,000 tons; whereas the export part of it to Africa amounted only to 13,000. Liverpool, he was sure, owed its greatness to other and very different causes; the Slave Trade bearing but a small proportion to its other trade.

Having gone through that part of the subject which related to the slaves, he would now answer two objections which he had frequently heard stated. The first of these was, that the abolition of the Slave Trade would operate to the total ruin of our navy, and to the increase of that of our rivals. For an answer to these assertions, he referred to what he considered to be the most valuable part of the report, and for which the House and the country were indebted to the indefatigable exertions of Mr. Clarkson. By the report it appeared, that, instead of the Slave Trade being a nursery for British seamen, it was their grave. It appeared that more seamen died in that trade in one year than in the whole remaining trade of the country in two. Out of 910 sailors in it, 216 died in the year, while upon a fair average of the same number of men employed in the trades to the East and West Indies, Petersburgh, Newfoundland, and Greenland, no more than eighty-seven died. It appeared also, that out of 3170, who had left Liverpool in the slave-ships in the year 1787, only 1428 had returned. And here, while he lamented the loss which the country thus annually sustained in her seamen, he had additionally to lament the barbarous usage which they experienced, and which this trade, by its natural tendency to harden the heart, exclusively produced. He would just read an extract of a letter from Governor Parrey, of Barbados, to Lord Sydney, one of the secretaries of state. The Governor declared he could no longer contain himself on account of the ill treatment, which the British sailors endured at the hands of their savage captains. These were obliged to have their vessels strongly manned, not only on account of the unhealthiness of the climate of Africa, but of the necessity of guarding the slaves, and preventing and suppressing insurrections; and when they arrived in the West Indies, and were out of all danger from the latter, they quarrelled with their men on the most frivolous pretences, on purpose to discharge them, and thus save the payment of supernumerary wages home. Thus many were left in a diseased and deplorable state; either to perish by sickness, or to enter into foreign service; great numbers of whom were for ever lost to their country. The Governor concluded by declaring, that the enormities attendant on this trade were so great, as to demand the immediate interference of the legislature.
