A j\Iasson-Scott plan is installed for removal of oiland grease from the water of condensation and for the purificationof the water for boiler feed purposes. This plant is capable ofdealing with 10,000 gallons per hour. The oil and grease which has passed through the steam enginesis in the fnrm of a divided eniulsinn, so fine in its character that it house wall and then down a special cable shaft into the bus-bars on the board are so divided that the auxiliary-generatorlighting and auxiliary-motor panels can be isolated from the maingenerator and heavy feeder panels by the operation of one switch,insuring the uninterrupted operation of the lighting system if anyaccident occurs to the main power circuits.
