=_Economy in Prime Outlay._=—The proportion of Engine Power in use to the power required for maximum supply is only about _one- third_, while any system, if running direct, requires a large portion of the plant to be duplicated. =_Economy in Working._=—The generating station is only at work a definite number of hours during the daytime, after which period the plant may be let out or utilized for other purposes, such as motive power, &c. =_Electro Motors_= for all purposes can be driven from the ordinary discharge mains. This is impossible where alternating currents are employed. =GUARANTEE.=—The E.P.S. Co. undertake to supply all the necessary renewals for the Storage Batteries in use in the above system at the rate of =12=% per annum on the actual first cost of the Batteries. E.P.S. Accumulators are already in use at the following Central-Stations:—Vienna; Berlin; Cadogan (London); Norwich; Taunton; Leamington; St. Austell; Detroit, U.S.A.; Allentown, U.S.A.; Blenheim, U.S.A.; Haverford, U.S.A.; Delaud, U.S.A. _Districts Surveyed, Plans, Specifications and Tenders submitted by the_ ELECTRICAL POWER STORAGE COMPANY, LTD., 4 GREAT WINCHESTER STREET, LONDON, E.C.
