FORE:THE EARL OF MAR RAISING THE PRETENDER'S STANDARD. (See p. 28.)In this Session the first step was taken in one of the greatest achievements of humanity which adorn the name of Britain. It was the grand preliminary towards annihilating the slave trade. The spirit of revolt against this odious trade had been gaining rapidly in the British mind. One of the earliest stabs given to it was by the pathetic story of Inkle and Yarico, in the "History of Barbadoes," by Lygon, which was taken up and amplified in the Spectator, and afterwards elaborated into an effective drama by Colman. Defoe, Dr. Johnson, Warburton in his "Divine Legation of Moses," and in his sermons so early as 1766, Voltaire, and other writers, had diffused a strong and sound feeling on the subject. It had been early attempted to establish the legal maxim, that a slave becomes a freed man in England; but in 1729 this had been positively pronounced against by Talbot and Yorke, then the highest legal authorities. But a more successful essay was made by Granville Sharp in 1772, in the case of James Somerset, and the principle was established, that the moment a slave set his foot on English ground he became free. In 1782 the Friends presented a petition to Parliament for the abolition of the slave trade. In 1785 Thomas Clarkson, then a student at the University of Cambridge, competed for and won the first prize for an essay on "The Slavery and Commerce in the Human Species," and this, which was undertaken as an academical exercise, led him to devote himself to the great work of the utter extinction of this evil. Mr. Ramsay, a clergyman of Kent, who had lived in St. Kitts, published a pamphlet on the same subject. The friends of Ramsay, Lady Middleton and Mrs. Bouverie, became zealous advocates of the cause, and finally Wilberforce resolved to make it the great object of his life. A society was now established in London, consisting only originally of twelve individuals, including the benevolent Mr. Thornton, and having Granville Sharp for its chairman. The members, however, were opulent merchants and bankers, and they set agents to work to collect information on the subject. The feeling rapidly spread; committees were formed in Manchester and other provincial towns for co-operation. 100 GB$29/month
