In the design of this station, the time- culation. The battery floors have a slope of 1 ft. from front torear of building to facilitate drainage. In the rear of the lowerroom is a sump to receive the drainage. The water is raisedfrom this point to the sewer by means of a centrifugal pumpdirect connected to a i-hp motor, located on the air-chamberfloor. The battery floors are covered with a layer of bricklaid flat and grouted and covered with pitch. Rooms arclighted by incandescent lamps, the sockets being tightly corkedwith wax to prevent the acid from entering and short-circuitingthem. All I-beams are entirely surrounded with concrete toprotect them from acid action. The air-chamber floor is on a level with the street. It has. FIG. 4.—GENERAL VIEW OF MACHINERY FLOOR—ST. LOUIS SUB-STATION honored custom of erecting a fine and elaborate building hasnot been followed, but instead a neat and substantial building,arranged to accommodate the necessary apparatus, has beenerected. Its plan is shown in Fig. 1, a cross section in Fig. 2,and an exterior view in Fig. 3. Below the street level are twofloors to accommodate the battery. These rooms are each 56ft. wide and 155 ft. long. Each contains 294 cells. Foundations of the building are entirely of concrete and restupon bed rock. The battery rooms are divided in the middleby a 5-ft. concrete wall, which extends from the lower floor tothe floor line of the air chamber, where it widens at a suitableangle to a width of 10 ft., and supports the two 30-in. brickwalls, 6 ft. 6 ins. apart, which extend to the rotary-converterfloor to form the machine foundations. Suitable openings leftin the concrete and brick walls permit of passage and a
