Another motor of 50 horse-power was GENERAL VIEW OF SAVAGE BASIN, SHOWING THE TOM soon added. While in other respectssimilar to the first, this motor was in-tended to be self-starting, with armatureand field in series through a currenttransformer, and on account of its fright-ful flashing it was fitted with a specialeight-part commutator of non-arcingmetal. This feature, however, provinga failure, was soon replaced by a sepa-rate starter.

Early in1894 a 50-horse, and, during the fall, a 75-horse motor were placed in SavageBasin, fourteen miles from the powerhouse. The former was soon replacedby a 100-horse motor, and in 1895 a100-horse motor was set up at Pandora.Except as to size, these motors weresubstantially identical. The 250-horsemotor was badly designed, and the polepieces were of cast iron. Its
