The main condenser for each engine will have a cooling sur-face of about 9,474 sq. ft., measured on the outside of the tubes, the water passing through thetubes. Two of the propellers will be right and one left, to be made of manganese bronze orapproved equivalent metal. There will be six double-ended boilers, about 15 ft.
