In the patent card manufactory of Mr. J. C. Dyer, Stone-street, London-road, he would observe the very curious mode of manufacturing the cards used for teasing or carding the cotton; and in the large establishments of Messrs. Sharp, Roberts, & Co., machinists and engineers, Faulkner-street, he would see the various manufactures of steam engines, both stationary and locomotive, boilers, steam looms, and every other piece of machinery required for manufacturing purposes in this part of the kingdom. In another branch of manufacture, that of silk, which is of growing importance and extent in Manchester, the visiter would be gratified by an inspection of the silk mill of Messrs. Royle and Crompton, Great Bridgewater-street. PUBLIC BUILDINGS, LITERARY AND SCIENTIFIC INSTITUTIONS. The Exchange and News Room, (now undergoing alteration and extension, for which end, the Post Office, now at the back of the building, is to be removed,) is situated at the foot of Market-street. It is a semi-circular building, with stone front, and the large room contains a full length portrait of Colonel Stanley, many years member for the county. The Town Hall, in King-street, is a fine structure, founded in 1822; by application to the porter, the stranger will obtain admittance to the hall or “large room,” which is very handsomely decorated with fresco paintings, and by rich mouldings, friezes, from the Elgin marbles, &c. The Royal Institution in Mosley-street is open twice every year, during the exhibitions of paintings; one being limited to those of old masters and deceased artists; the other restricted to those of modern and living artists. The entrance hall and sculpture gallery are worth notice. Admission a shilling. Nearly adjoining, at the back of the Royal Institution, is the Manchester Athenæum, now in process of erection, the members of which at present occupy the lower wing of the Royal Institution, with an entrance in Bond-street. The front of the Athenæum is also in Bond-street, and when it is finished the two buildings will form a very pleasing proof of the architectural resources of Mr. Barry, the architect of the two new houses of parliament. The Manchester Mechanics’ Institution is a spacious brick edifice in Cooper-street, with large lecture theatre, good library, and commodious class rooms. To the Athenæum and the Mechanics’ Institution there is no difficulty of access. The Literary and Philosophical Society of Manchester, one of the oldest and most celebrated of provincial institutions, having been founded in 1781, has distinguished itself by its annual volumes of published memoirs, and is now distinguished in the person of its President, the venerable Dr. Dalton. Its Hall is in George-street, nearly opposite St. James’s Church; but as the sittings of the society are not daily, little information can be given as to the admission of strangers. Scientific men would doubtless find no difficulty in obtaining an introduction.
