In the spring of 1851, two most interesting fugitives, William and Ellen Craft, arrived in England. They had made their escape from the South, the wife disguised in male attire, and the husband in the capacity of her slave. William Craft was doing a thriving business in Boston, but in 1851 was driven with his wife from that city by the operation of the Fugitive Slave Law. For several months they travelled in company with Mr. Brown in this country, deepening the disgust created by Mr. Brown's eloquent denunciation of slavery by their simple but touching narrative. At length they were enabled to gratify their thirst for education by gaining admission to Lady Byron's school at Oakham, Surrey. In the month of May, Mr. Brown and Mr. and Mrs. Craft were taken by a party of anti-slavery friends to the Great Exhibition. The honourable manner in which they were received by distinguished persons to whom their history was known, and the freedom with which they perambulated the American department, was a salutary rebuke to the numerous Americans present, in regard to the great sin of their country--slavery; and its great folly--prejudice of colour. A curious circumstance occurred during the Exhibition. Among the hosts of American visitors to this country was Mr. Brown's late master, Enoch Price, who made diligent inquiry after his lost piece of property--not, of course, with any view to its reclamation--but, to the mutual regret of both parties, without success. It is gratifying to state that the master spoke highly of, and expressed a wish for the future prosperity of, his fugitive slave; a fact which tends to prove that prejudice of colour is to a very great extent a thing of locality and association. Had Mr. Price, however, left behind him letters of manumission for Mr. Brown, enabling him, if he chose, to return to his native land, he would have given a more practical proof of respect, and of the sincerity of his desire for the welfare of Mr. Brown. It would extend these pages far beyond their proposed length were anything like a detailed account of Mr. Brown's anti-slavery labours in this country to be attempted. Suffice it to say that they have everywhere been attended with benefit and approbation. At Bolton an admirable address from the ladies was presented to him, and at other places he has received most honourable testimonials.
