icle showsthe Franklin with a four-car train. Inher experimental runs she has repeatedlydrawn this train with ■ less than three-fourths the current-generating capacityin use, up and down the line at a speed of35 miles per hour. With the same current and three un-loaded cars, a speed of 30 miles per hourwas kept up uninterruptedly for a longtime. The commercial outcome of the achieve-ments of the Franklin could hardly beforecast; but, in conpideration of the^wellsubstantiated claim that the substitutionof such motors on the New York elevatedrailways would reduce the running ex-penses aboat 50 per cent, and. this evenwhen including, as a fixed charge, theinterest on the cost of re-equipment, andalso without allowing any rebate for thesale of the present steam locomotives,which are of standard gauge and avail-able on any ordinary track, there should be littledoubt as to the probable line of action of such a saga-cious and far-sighted management as that of the NewYork elevated railways.

THE DAFT ELECTRIC MOTOR ON THE NINTH AVE. ELEVATED RAILWAY NEW YORIL Electrical Storage Street Cars. The Julien Electric Company is running three carson Fourth and Madison Avenues, this city. Until re-cently, the. batteries were changed after each round tripof 13 miles. Now they are changed after the secondround trip, or 24 miles. Even then, the battery requiresbut about three hours charge before it is put on thecar again. The company hopes very soon to makethree round trips, or thirty-six miles, with one charge.If it can accomplish this, there will be requiredbutonecharge of battery a day, thus making a great saving oftime and labor. In other words, horses will be changedbut once a day. All this is due to the scientific progressthe Julien company is making, more especially in thestorage battery. The company has done a great deal of experimental workon the three cars nowin use, and has putthem to such practi-cal tests as to be ableto settle on a stand-ard. Hereafter, thestandard car o
