On the 30th of October several letters were read: one of these was from Brissot and Claviere conjointly; in this they acknowledged the satisfaction they had received on being considered as associates in the humane work of the abolition of the Slave Trade, and correspondents in France for the promotion of it. They declared it to be their intention to attempt the establishment of a committee there, on the same principles as that in England; but, in consequence of the different constitutions of the two governments, they gave the committee reason to suppose, that their proceedings must be different, as well as slower than those in England, for the same object.
A second letter was read from Mr. John Wesley. He said that he had now read the publications which the committee had sent him, and that he took, if possible, a still deeper interest in their cause. He exhorted them to more than ordinary diligence and perseverance; to be prepared for opposition; to be cautious about the manner of procuring information and evidence, that no stain might fall upon their character; and to take care that the question should be argued, as well upon the consideration of interest as of humanity and justice, the former of which he feared would have more weight than the latter; and he recommended them and their glorious concern, as before, to the protection of Him who was able to support them.
Letters were read from Dr. Price, approving the institution of the committee; from Charles Lloyd of Birmingham, stating the interest which the inhabitants of that town were taking in it; and from William Russell, Esq. of the same place, stating the same circumstance, and that he would co-operate with the former in calling a public meeting, and in doing whatever else was necessary for the promotion of so good a cause. A letter was read also from Manchester, signed conjointly by George Barton Thomas Cooper, John Ferriar, Thomas Walker, Thomas Phillips, Thomas Butterworth Bayley, and George Lloyd, Esqrs., promising their assistance from that place. Two others were read from John Kerrich, Esq., of Harleston, and from Joshua Grigby, Esq., of Drinkston, each tendering their services, one for the county Of Norfolk, and the other for the county of Suffolk. The latter concluded by saying, "With respect to myself, in no possible instance of my public conduct can I receive so much sincere satisfaction, as I shall, by the vote I will most assuredly give in parliament, in support of this most worthy effort to suppress a traffic, which is contrary to all the feelings of humanity, and the laws of our religion."
A letter was read also at this sitting from Major Cartwright, of Marnham, in which he offered his own services, in conjunction with those of the Rev. John Charlesworth, of Ossington, for the county of Nottingham.
"I congratulate you," says he, in this letter, "on the happy prospect of some considerable step at least being taken, towards the abolition of a traffic, which is not only impious in itself, but of all others tends most to vitiate the human mind.
"Although procrastination is generally pernicious in cases depending upon the feelings of the heart, I should almost fear that, without very uncommon exertions, you will scarcely be prepared early in the next sessions, for bringing the business into parliament with the greatest advantage. But, be that as it may, let the best use be made of the intermediate time; and then, if there be a superintending Providence, which governs everything in the moral world, there is every reason to hope for a blessing on this particular work."
The last letter was from Robert Boucher Nickolls, dean of Middleham, in Yorkshire. In this he stated that he was a native of the West Indies, and had travelled on the continent of America. He then offered some important information to the committee as his mite, towards the abolition of the Slave Trade, and as an encouragement to them to persevere. He attempted to prove, that the natural increase of the negroes already in the West Indian islands would be fully adequate to the cultivation of them, without any fresh supplies from Africa; and that such natural increase would be secured by humane treatment. With this view, he instanced the two estates of Mr. MacMahon and of Dr. Mapp, in the island of Barbados. The first required continual supplies of new slaves, in consequence of the severe and cruel usage adopted upon it. The latter overflowed with labourers in consequence of a system of kindness, so that it almost peopled another estate. Having related these instances, he cited others in North America, where, though the climate was less favourable to the constitution of the Africans, but their treatment better, they increased also. He combated, from his own personal knowledge, the argument, that self-interest was always sufficient to insure good usage, and maintained that there was only one way of securing it, which was the entire abolition of the Slave Trade. He showed in what manner the latter measure would operate to the desired end: he then dilated on the injustice and inconsistency of this trade, and supported the policy of the abolition of it, both to the planter, the merchant, and the nation.
This letter of the Dean of Middleham, which was a little Essay of itself, was deemed of so much importance by the committee, but particularly as it was the result of local knowledge, that they not only passed a resolution of thanks to him for it, but desired his permission to print it.
The committee sat again on the 13th and 22nd of November. At the first of these sittings, a letter was read from Henry Grimston, Esq., of Whitwell Hall, near York, offering his services for the promotion of the cause in his own county. At the second, the Dean of Middleham's answer was received. He acquiesced in the request of the committee; when five thousand of his letters were ordered immediately to be printed.
On the 22nd a letter was read from Mr. James Mackenzie, of the town of Cambridge, desiring to forward the object of the institution there. Two letters were read also, one from the late Mr. Jones, tutor of Trinity College, and the other from Mr. William Frend, fellow of Jesus College. It appeared from these, that the gentlemen of the University of Cambridge were beginning to take a lively interest in the abolition of the Slave Trade, among whom Dr. Watson, the bishop of Llandaff, was particularly conspicuous. At this committee two thousand new Summary View were ordered to be printed, and the circular letter to be prefixed to each.
