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 commitee, 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 Negros 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. Mac Mahon and of Dr. Mapp in the island of Barbadoes. 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 ensure 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 commitee, 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 commitee sat again on the thirteenth and twenty-second of November. At the first of these sittings, a letter was read from Henry Grimston, esquire, 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 commitee; when five thousand of his letters were ordered immediately to be printed. On the twenty-second 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 commitee two thousand new Summary Views were ordered to be printed, and the circular letter to be prefixed to each.
