The great development in late years of electrical science calls for a large building in which to display one of the most novel and brilliant of all the exhibits in the fair. The Electrical Building, 345 feet wide and 700 feet long, has its south front on the great Quadrangle, its north front on the lagoon, its east front toward the Manufactures Building, and its west front toward the Hall of Mines and Mining. Its plan comprises a longitudinal nave 115 feet wide and 114 feet high, with a central transept of the same dimensions. These have a pitched roof. The remainder of the building, filling the external angles of the nave and transept, is 62 feet high with a flat roof. The outer walls are composed of a continuous series of Corinthian pilasters resting upon a stylobate, and supporting a massive entablature. At the centre of the north side is a pavilion flanked by two towers 195 feet high. At its centre is a huge semicircular window, above which, 102 feet from the ground, is an open gallery commanding a splendid view of the lake and park. At the south side is a vast niche 78 feet wide and 103 feet high, its opening framed by a semicircular arch. In the centre of this niche, upon a lofty pedestal, is a colossal statue of Franklin. The east and west central pavilions are composed of towers 168 feet high. At each of the four corners of the building is a pavilion with a tower 169 feet high. The building also bears 54 lofty masts, from which banners will be displayed by day and electric lamps at night. The Fisheries Building consists of a large central structure with two smaller polygonal buildings connected with it on either end by arcades. The total length is 1,100 feet, and the width 200 feet. In the central portion will be the general fisheries exhibit; in one of the polygonal buildings the angling exhibit, and in the other the aquaria. The external architecture is Spanish Romanesque. The ingenuity of the architect has designed after fishes and other sea forms all the capitals, medallions, brackets, cornices, and other ornamental details. The aquaria will contain about 140,000 gallons of water, 40,000 of it being salt. They will consist of a series of ten tanks, with glass fronts to afford an easy view of their contents.
