"How many non-slaveholders elsewhere are thus interested in the products of slaves? Is it not worthy the attention of genuine philanthropists to inquire whether cotton cannot be profitably cultivated by free labor?" SOIRÉE AT WILLIS'S ROOMS--MAY 25. MR. JOSEPH STURGE took the chair, announcing that he did so in the absence of the Earl of Shaftesbury, who was prevented from attending. It was announced that letters had been received from the Duke of Newcastle and the Earls of Carlisle and Shaftesbury, expressing their sympathy with the object of the meeting, and their regret at being unable to attend. The Secretary, SAMUEL BOWLEY, Esq., of Gloucester, then read the address, which was as follows:-- "MADAM: It is with feelings of the deepest interest that the committee of the British and Foreign Antislavery Society, on behalf of themselves and of the society they represent, welcome the gifted authoress of Uncle Tom's Cabin to the shores of Great Britain. "As humble laborers in the cause of negro emancipation, we hail, with emotions more easily imagined than described, the appearance of that remarkable work, which has awakened a world-wide sympathy on behalf of the suffering negro, and called forth a burst of honest indignation against the atrocious system of slavery, which, we trust, under the divine blessing, will, at no distant period, accomplish its entire abolition. We are not insensible to those extraordinary merits of Uncle Tom's Cabin, as a merely literary production, which have procured for its talented authoress such universal commendation and enthusiastic applause; but we feel it to be our duty to refer rather to the Christian principles and earnest piety which pervade its interesting pages, and to express our warmest desire, we trust we may say heartfelt prayer, that He who bestowed upon you the power and the grace to write such a work may preserve and bless you amid all your honours, and enable you, under a grateful and humble sense of his abundant goodness, to give him all the glory.
