The average load on the system isgoo amp. at 220 volts, which is the pressure employed for the oper-ation of the motors, of which there are 30, ranging in capacity from3 to 30 hp; 800 lights are scattered throughout the buildings andthey, as well as the heating appliances, are operated on iio-voltcircuits. That these devices are important factors in the operationof a modern hat factory may be gathered from the fact that one-halfof the entire average output of the plant described above is con-sumed by electrically-heated devices, approximating 100 kw. The designers and owners of this establishment, where steam andgas have been so largely supplanted by electricity, must certainlyhave been convinced of the truth of the statement, made recently bya well-known engineer, that An electrically-driv
