The foresight shown in the recommendation andauthorization of this wholesale reconstruction and re-equipment has been well established by results already. obtained. The economy of replacing inefficient appar-atus by apparatus which is the production of the highest(grade of engineering is, in this instance, no longer apossibility but an established fact. I One of the generating stations of the R. E. Co. isdevoted exclusively to supplying direct current arcservice. The equipment of the second or Queen street station,for serving light from an alternating system, with aspare series arc capacity, prior to its reconstruction,consisted of 18 alternators, 6 exciters and 9 arc ma-chines, with their numerous belts, pulleys and shafting,shown in diagrams 1 and 2, representing the apparatuson the ground and first flats. The D. C. power genera-tors and engines are located in a separate building. The upright engine, known as No. i, shown next toQueen street in diagram i, was connected by two 30belts to a line shaft from which were operated four 75k. w. and two 150 k. w. alternators and 2 from the line shafting connected to No. 2engi
