Mr. (now Lord) Grenville would not detain the house by going into a question, which had been so ably argued; but he should not do justice to his feelings, if he did not express publicly to his honourable friend, Mr. Wilberforce, the pleasure he had received from one of the most masterly and eloquent speeches he had ever heard,--a speech, which, while it did honour to him, entitled him to the thanks of the house, of the people of England, of all Europe, and of the latest posterity. He approved of the propositions, as the best mode of bringing this great question to a happy issue. He was pleased also with the language which had been held out with respect to foreign nations, and with our determination to assert our right of preventing our colonies from carrying on any trade, which we had thought it our duty to abandon. Aldermen Newnham, Sawbridge, and Watson, though they wished well to the cause of humanity, could not, as representatives of the city of London, give their concurrence to a measure, which would injure it so essentially as that of the abolition of the Slave-trade. This trade might undoubtedly be put under wholesome regulations, and made productive of great commercial advantages. But, if it were abolished, it would render the city of London one scene of bankruptcy and ruin. It became the house to take care, while they were giving way to the goodness of their hearts, that they did not contribute to the ruin of the mercantile interests of their country. Mr. Martin stated, that he was so well satisfied with the speech of the honourable gentleman, who had introduced the propositions, and with the language held out by other distinguished members on this subject, that he felt himself more proud than ever of being an Englishman. He hoped and believed, that the melancholy predictions of the worthy aldermen would not prove true, and that the citizens of London would have too much public spirit to wish that a great national object (which comprehended the great duties of humanity, and justice) should be set aside, merely out of consideration to their own private interests.
