FIG. -DIAGRAM OF34TH SWITCHBOARD CONNECTIONS ATSTREET STATION can form into peroxide before breaking up, of from ten tofifteen times the extent of its initial formation. Thenegative plate is a regular chloride negative, which hasbeen found much superior to any other form of negativeplate- The process of manufacture produces a negativeactive material, which is of a perfectly porous crystallinestructure, with the axes of the crystals perpendicular tothe surface of the plate. The charge and discharge rateof this type of cell is very high, as compared with theolder pasted form, the batteries being regularly ratedto discharge their entire capacity in one hours time, ifneeded. The cells are connected in series, and at present 252are in use at the Oakland station, and 244 at the Thirty- PleasantStation. FIG. 4.—DIAGRAM SHOWING LOCATION OF STATIONS—UNITED TRACTION CO fourth Street station. The number to be placed in seriesis varied according to the voltage which the engineers wishto obtain at the different points. The Oakland station isan old cable station, and the batteries occupy the placeformerly devoted to the tension run. The old cable enginesare still in use. They are two in number, each driving oneend of a shaft, but the main driving drums on this shafthave been replaced by an 800 k. w. generator, which isthus directly driven. The battery of 252 cells is con-nected in parallel across the bus bars, as would be the casewith another generator, and are controlled directly on theswitchboard by a separate generator panel, with circuitbreaker, ammeter, voltmeter and quick-break switch. Theammeter is not of the ordinary type, but differential read- switchboard, the bus bars of which are fed directly fromthe three other power stations of the company, as shownin Fig. 2. As will be se
