In traction work there is only one reliablemethod of determining the life of the battery, andthat is on the basis of cxi mileage. It is nonsenseto talk about batteries lasting eight months or18 months, unless there is a record, at the sametime, of the amount of work accomplished,measured in electrical horse power hours. Thehighest record yet obtained, of which the writerhas any reliable knowledge, is that of a single setof 108 accumulators making over 6,000 record was made under the most trying andunfavorable circuriistun es. Assuming that the bat-. w/f fm/m/m// SIDE ELEVATION OF THE NEW YORK & BROOKLYN BRIDGE STATION AND FLOOR PLAN OF THE TRACKS. wiched, will be run across the bridge. There willbe two cables running. One will pull one trainover to New York, and 45 seconds later the othercable will pull another train on a track threeinches nearer to Governors Island. The reasontwo cables are used is to avoid switching into thetwo tracks at the New York end. The first traingoes to the outside incoming track, and secondslater the second train arrives at the inside incom-ing platform and the passengers get off. Thetrain will be switched by an engine, as at present,and tlie outside incoming train becomes the insideoutgoing train, and vice versa. One of these daysthe switching will all he done by the cable, but thegrip on the bridge cars is not capable of droppingone rope and picking up another. At present the trains run on 90 seconds the new tei minus is completed they willrun on about 4.
