The main cir-culating pump is of the Worthington turbine type. It is locatedin the basement, and is directly connected with a Junior engine. mounted on a common bed-plate. This pump will deliver6000 gals, of water per minutes against a 30-ft. head whileoperating at a speed not to exceed 320 r. p. m., and underthese conditions is capable of developing an efficiency of notless than 65 per cent of the power delivered on the pump air cooler and a lo-in. x i8-in. x i8-in. Worthington rotativedry vacuum pump serve to abstract all saturated air vapor fromthe spray chamber of the condenser. The water for condensingpurposes is obtained from the in-take well connected withRoaring Brook reservoir, and, after passing through the con-denser, is discharged into a 36-in. concrete conduit which leads
