The number of arc lamps used for streetlighting is 440 of the type on series circuits, with an esti-mated equivalent capacity of 4,400 incandescent lamps of 16 cp arc lamps on constant-pressure circuits number 519, withindividual ratings of 4 to 25 amp., there being 10 of the largest size,and the number rated at 6 amp. each is 482. Estimated on the basisof i6-cp incandescent lamps, the equivalent capacity of these com-mercial arcs is 10,030 in number. Commercial incandescent lampsnumber , and their equivalent capacity in lamps of 16 cp is 79,-. FIG. 13.—A GROUP OF TR.\NSF0R.\IERS, ALBANY. 180. In candle-power these incandescent lamps range from 4 to 100,and the number of lo-cp lamps is 16,820, of i6-cp 63,769. and ofloo-cp 6. All motors are of the induction type, and their total number is173. with a combined rating of 671 hp, and an equivalent capacity of11,140 incandescent lamps of 16 cp each. These motors range from1/16 to 50-hp capacity, and there are five of the 20-hp, five of the30-hp, and two of the 50-hp size. The equivalent rating of all thelamps and motors above named is 100,350 incandescent lamps of16 candle-power. Besides the above connected load the Schenectady Railway Com-pany has secured a twenty-year contract, subject to confirmation atthe end of each three-year period, to pump all of the public watersupply for the city. This water is pumped into standpipes under ahead of 110 pounds and with a suction of 6 pounds. For the workof pumping there have been provided two vertical turbine centri
