In front of this entrance is a heavy balustrade of terra-cotta, surmounted by ornamental lamps. Over the main door is a panel of terra-cotta, containing a bas-relief representation of 'The Young Athletes.' There is a beautiful winding stair, of oak, I which conducts from the base of one of the towers to the topmost story of the building. The floor of the entrance is laid in a Roman Mosaic of tiles, black, red and salmon color, three-quarters of an inch square. The gymnasium proper is a room forty by eighty feet, without a post or pillar resting upon the floor. Light but beautiful trusses, which are self-supporting, sustain the heavy roof. The floor is of the choicest vertical grain yellow pine; the walls of buff terra-cotta brick ; ceilings, trusses and window-work of white and yellow pine, finished in their native color; the windows of French plate; the doors of polished oak ; trimmings and gas-fixtures of solid bronze, and polished brass, made expressly for this building. The running track, which is elevated .about eight and a half feet above the floor of the main room, extends entirely around the building, and is suspended from the roof. Behind it (at one end) there is a gallery for the accommodation of visitors. Under the floor of j the main room is the bowling alley, one hundred by twenty feet. It is on the south side, and is fitted I with four alleys, in the most approved modern style. I This room, although below the surface of the ground, is most admirable lighted by a row of windows in j amber-colored cathedral glass, in circular form and set in lead. On the opposite side of the building are the dressing-rooms, fitted up with lockers and all suitable modern conveniences. Beyond these are the boiler and fuel-rooms.
