A space of ten yards square will ac-commodate a battery having capacity of one thousand kilo-watt hours. The cost of containers or holders of the active-or working agent is less with accumulators than with steam,air or water, and depreciation and repairs thereon are less;the life is also longer. With steam, air and water storage load diagrams showthat the pressure or work line falls rapidly, whereas with ac-.

RqitaJizingor Controlling Pressures.—Accumulators per-form this, which is one of the most important requirementsin the distribution of electrical currents, in manner most per-fect. For steadiness and constancy no source of electricityor power can compare with a storage battery. Each elementand series of elements making up a battery begins and endswith a negative terminal and thus differs m marked charac-teristics from all other forms of apparatus. An element orseries of elements will transler any excessof current (amperes)contained to others of lower electromotive force and thusautomatically equalize the total electromotive force. Short-circuits and grounds are promptly blown by accumulationfrom their quickly responding store of accumulated fulfilling this function they maintain the electromotiveforce on t
