In October, 1902, an appropriation of $20,000 was madeto carry out these suggestions. The recommendations advocated theremoval of the original belted engine with the two arc dynamos and. FIG. 2.—VIEW OF INTERIOR OF STATION. the substitution for these units, of a motor-driven arc machine,capable of supplying 130 enclosed arc lamps, and the installation ofa large modern unit to assist in supplying the commercial load increased so rapidly that the existing equipment wasthreatened with serious overloads, until the installation of the newapparatus was completed. One of the advantages of the new arrangement is that the arclighting circuits are no longer dependent on any one engine fortheir operation, as the motor is driven directly from the bus-bars,and any of the five units, operating at 250 volts, has sufficient capacityto operate it. The space occupied by the motor-driven arc unit isso much less than the previous belted arrangement that it was pos-sible also to place the 165-kw direct-connected unit in positionwithout any addition to the building, or changes to the remainingapparatus. Careful records of the load show that this unit is n
