Electric Ry. Joi New Bedford Carhouse—Plan of Second Floor ment required, and this apparatus is labeled as shown inthe photograph, with cables run in an open molding alongthe face of the wall to the motors. A standard car con-troller wired to the supply circuit of the building enablesthe motors to be operated at the convenience of the in- feeder switch and overhead system to the car, giving theembryo motorman and conductor a clear idea of the mean-ing of the electric circuit. To illustrate the phenomena ofthe magnetic field a piece of an old axle has been woundwith wire and connected through a snap switch with theelectrical service of the building, and the establishment oflines of force as shown by iron filings, attraction and repul-sion and the powerful mechanical pull exercisedunder proper conditions by a large number ofampere-turns are frequently exhibited. Thisapparatus is portable, and another portableequipment illustrated in one of the views on thenext page shows the use of th
