On April 15th we visited the "State Asylum for the Deaf and Dumb," a most interesting institution, where the Principal (Dr. Gillett) conducted us to a large hall, in which the inmates of the Establishment (consisting of 460 deaf and dumb pupils, male and female, and 35 teachers) were at dinner. All eyes being immediately directed towards us, Dr. Gillett explained at once by signs and finger language, who the visitors were; and announced that at half-past one, Mr. George Müller, of Bristol, England, would address the whole assembly in the Chapel; upon which, a young man (one of the deaf mutes) stood up, and with his fingers said--"My ears itch to hear him." Our attention was then directed to 'the happy family' seated at two adjoining tables, the members of which included a Pole, some Jews, a German, a Portuguese, a Frenchman, a negro, a Swede, an Englishman, an Irishman, a Scotchman, an American, and an Italian. At the hour appointed, we went into the Chapel, which adjoins the Institution, and there, from a high platform (with Dr. Gillett standing close to him, who, with his fingers, interpreted as rapidly as the words were uttered) Mr. Müller preached the gospel to the large community of deaf and dumb, and afterwards (by particular request) gave a very brief account of the Orphan work on Ashley Down, Bristol, and the other branches of the Scriptural Knowledge Institution. At the close of his address, an attempt was made by the--_hearers_ (can they be called?) to express their satisfaction by applause; but the desire was checked instantly by Dr. Gillett. We then distributed some gospel tracts amongst them, and afterwards visited the educational and industrial departments of the Institution, including a room devoted to drawing, painting, and other artistic employments, in which some of the deaf and dumb pupils excel. All the furniture used in the Establishment, as well as the boots and shoes worn by its inmates, are made on the premises. This is the largest Deaf and Dumb Institution in the world. Before our departure from Jacksonville, Mr. Müller preached twice at the Presbyterian Church; but, having made engagements for other places, was unable to prolong his visit.
