The cost of the power-house, persquare foot, per kilowatt, would be about 65 per cent, less for a. chinery when running Idle; (c) the total power used by the shaft-ing, machinery and work; (d) efficiency of electric trans-niLssion. The tests were made under actual running conditions, the testfor each room being continued for one-h:ilf day, with regular work-ing load, and readings of the watt meler were taken every twominutes.

The analysisof those tests would indicate that, with the turbo-generator drivinginduction motors, and with tin evaporation of lbs. of waterper pound of coal, a brake horse-power can be delivered from thejmlley of the motor for about 2/l> lbs. of coal with a turbine of thissize running under average economy.
