On its arrival there on the fifth of July, petitions from London and Liverpool still followed it. The prayer of these was against the general tendency of it, but it was solicited also that counsel might be heard in a particular case. The solicitation was complied with; after which the bill was read a second time, and ordered to be committed.
On the seventh, when it was taken next into consideration, two other petitions were presented against it. But here so many objections were made to the clauses of it as they then stood; and such new matter suggested, that the Duke of Richmond, who was a strenuous supporter of it, thought it best to move that the commitee, then sitting, should be deferred till that day seven-night, in order to give time for another more perfect to originate in the lower house.
This motion having been acceded to, Sir William Dolben introduced a new one for the third time into the Commons. This included the suggestions which had been made in the Lords. It included also a regulation, on the motion of Mr. Sheridan, that no surgeon should be employed as such in the slave-vessels, except he had a testimonial that he had passed a proper examination at Surgeons'-Hall. The amendments were all then agreed to, and the bill was passed through its several stages.
On the tenth of July, being now fully amended, it came for a third time before the Lords; but it was no sooner brought forward than it met with the same opposition as it had experienced before. Two new petitions appeared against it, one from a certain class of persons in Liverpool, and another from Miles Peter Andrews, esquire, stating that, if it passed into a law, it would injure the sale of his gunpowder, and that he had rendered great services to the government during the last war by his provision of that article. But here the Lord Chancellor Thurlow reserved himself for an effort, which, by occasioning only a day's delay, would in that particular period of the session have totally prevented the passing of the bill. He suggested certain amendments for consideration and discussion, which, if they had been agreed upon, must have been carried again to the lower house and sanctioned there before the bill could have been complete. But it appeared afterwards, that there would have been no time for the latter proceeding. Earl Stanhope, therefore, pressed this circumstance peculiarly upon the Lords who were present. He observed, that the King was to dismiss the parliament next day, and therefore they must adopt the bill as it stood, or reject it altogether. There was no alternative, and no time was to be lost. Accordingly he moved for an immediate division on the first of the amendments proposed by Lord Thurlow. This having taken place, it was negatived. The other amendments shared the same fate; and thus, at length, passed through the upper house, as through an ordeal as it were of fire, the first bill that ever put fetters upon that barbarous and destructive monster, The Slave-trade.
The next day, or on Friday, July the eleventh, the King gave his assent to it, and, as Lord Stanhope had previously asserted in the House of Lords, concluded the session.
While the legislature was occupied in the consideration of this bill, the Lords of the Council continued their examinations, that they might collect as much light as possible previously to the general agitation of the question in the next session of parliament. Among others I underwent an examination. I gave my testimony first relative to many of the natural productions of Africa, of which I produced the specimens. These were such as I had collected in the course of my journey to Bristol and Liverpool, and elsewhere. I explained, secondly, the loss and usage of seamen in the Slave-trade. To substantiate certain points, which belonged to this branch of the subject, I left several depositions and articles of agreement for the examination of the council. With respect to others, as it would take a long time to give all the data upon which calculations had been made and the manner of making them, I was desired to draw up a statement of particulars, and to send it to the council at a future time. I left also depositions with them relative to certain instances of the mode of procuring and treating slaves.
The commitee also for effecting the abolition of the Slave-trade continued their attention, during this period, towards the promotion of the different objects, which came within the range of the institution.
They added the reverend Dr. Coombe, in consequence of the great increase of their business, to the list of their members.
They voted thanks to Mr. Hughes, vicar of Ware in Hertfordshire, for his excellent Answer to Harm's Scriptural Researches on the Licitness of the Slave-trade, and they enrolled him among their honorary and corresponding members. Also thanks to William Roscoe, esquire, for his Answer to the same. Mr. Roscoe had not affixed his name to this pamphlet any more than to his poem of The Wrongs of Africa. But he made himself known to the commitee as the author of both. Also thanks to William Smith and Henry Beaufoy, esquires, for having so successfully exposed the evidence offered by the slave-merchants against the bill of Sir William Dolben, and for having drawn out of it so many facts, all making for their great object, the abolition of the Slave-trade.
As the great question was to be discussed in the approaching sessions, it was moved in the commitee to consider of the propriety of sending persons to Africa and the West Indies, who should obtain information relative to the different branches of the system as they existed in each of these countries, in order that they might be able to give their testimony, from their own experience, before one or both of the houses of parliament, as it might be judged proper. This proposition was discussed at two or three several meetings. It was however finally rejected, and principally on the following grounds: First, It was obvious, that persons sent out upon such an errand would be exposed to such dangers from various causes, that it was not improbable that both they and their testimony might be lost. Secondly, Such persons would be obliged to have recourse to falsehoods, that is, to conceal or misrepresent the objects of their destination, that they might get their intelligence with safety; which falsehoods the commitee could not countenance. To which it was added, that few persons would go to these places, except they were handsomely rewarded for their trouble; but this reward would lessen the value of their evidence, as it would afford a handle to the planters and slave-merchants to say that they had been bribed.
