554 The Architectural Review and American Builders Journal. [Mar., D D, Rooms for sick, or private pa- tients, having entrances from a passage off of the cross corridor. E E E are the Alcoves in the centre of the corridors, overlooking the front grounds. FFF are the Porches on the rear, and apply to all the stories, as well as to all the wards. They are intended ex- clusively for the patients. G G, G G, the extreme wings, for the most excited patients. H H, the Court-yards to the same. I I, the Underground Duct, which con- nects with the cold-air chamber in the cellar, at the centre of each department. J, the Workshop. K, the Engine and Boiler-house. L, the Laundry. M M, the Fans within the towers ; one at the workshop, and the other at the laundry. N, the Chimney Stack, within the boiler-house. It also indicates a pass- age-way from one fan to the other. OOO, Dining-rooms. The heating and ventilating are alike intended to be on the most improved and perfect plan, by the direct current through flues, prepared for the purpose, in every rooTif and hall, independent of each other, and connected with a hori- zontal shaft laid along the cellar floor ; also connected with vertical shafts con- structed in the walls of the stairs. These latter are three feet square each. There are two in each ward ; thus giving one to each range of rooms. Those shafts are topped out high above the roof, and heated by a coil of steam -pipe to ratify and facilitate the current. The building will be thoroughly warmed by steam generated at the boiler-house ; a system which avoids the necessity for fire in any part of the establishment, except in the kitchen range. The steam is likewise used for the purposes of washing, cooking, and heating water, for bathing and ether objects. A railway extends the entire length of the building, and connects with the kitchen, which is under the Amusement Hall, being used to convey the food to the dining-rooms of the various wards, as well as to carry the clothes to and from the laundry-build- ing, articles to and from the workshop, and for conveying stores to the upper story rooms. THE NEW CITY HALL: Pittsburgh, Pennsylvania. THROUGH the kindness of Mr. J. W. Kerr, Architect, of Pittsburgh, Pa , we are enabled, on this occasion, to present to our readers his accepted de- sign for the New City Hall, at Pitts- burgh, a building, the need of which, long felt, had become imperative. Under Mr. Kerr's efficient direction, plans and working drawings have been prepared, and every preliminary arrange- ment made, during the present winter: such as forwarding the cut-stone work, iron beams for the floors, amassing bricks, and materials generally ; so that, on the opening of next spring, building operations will be commenced, and pushed on with rapidity and vigor. The Hall will be ready for occupancy some time in 1810. The style of the architecture is that known as " Renaissance" — similar to that of the City Hall, at Boston — being a combination of ornamental pilasters and cornices to each storjr, and moulded dressings to all openings. The City Hall will have a front of one hundred and twenty feet on Smithfield street, with one hundred and ten feet depth, to the extreme rear. The body of the building will be one hundred and twenty feet long by one hundred feet deep — set back eight feet from Smitb- field street, with a central projection of forty feet wide on the line of the street, forming a base to a tower of forty feet square, to be carried up in the front of the edifice. The body of the pile will have three full stories and an attic — the tower reaching two stories higher.
