That this conclusion was correct Isshown by the descriptions and illustrations of thenew machines which are presented herewith. The new generator which the company Is build-ing for street railway and direct current powertransmission shown In Fig. 1, is of 250 horsepower, of the well-known four-pole type and is aslow speed machine. The frame is cast in onepiece with three bearings, which are of ball andsocket selE-oUing type. The field magnets are ofwrought iron and are wound with enough copperto allow them to run perfectly cold. The armature is series wound and Insulated en-tirely with mica. With these two-path windings—the only kind used by this company—there can. FIG. 1.

TheWalker company holds to the view that the onlyway to correct this evil is entirely to disconnectthe motor itself from iron to iron contact with theaxle and thus prevent not only the hammer blowdue to the weight of the motor, but the inertiablow due to the unyielding mass of the have been made to accomplish this by The motor being built by the Walker Manufac-turing Company embodies these suggestions ofpractical experience. It is a four-pole steel motor,weighing 1,300 pounds, has an easy capacity of 35horse power, will run at any speed up to 25 milesan hour, is controlled by a series parallel control-ler, of excellent design and great slmrllcity, an
