Each turbine has a maximum ca-pacity of 3600 when operating under an effective headof 75 ft. and at a normal turning speed of 250 rev. per turbines are located at such a height that the centerof the runners is 20 ft. above tail water. The water is discharged through steel lined concretedraft tubes, which are 71 in. diam. at the discharge from therunners and increase to an elliptical section of 9 ft. by 7 ft at theoutlets, which are horizontal, there ; a 90 degree bendin the tubes. The linings are made of % in. steel plates,which were fitted together in the shop and shipped knockeddown. The turbines are of the spiral case type and are fittedwith heavy cast iron distance rings which carry the gen-erators. The weight of the revolving parts of each gener-ator and turbine is carried on a roller thrust bearing mounted.

To insure continuity of serv-ice ir. case of accident, 1a steam-electric station at Mira-flores, erected a few years ago to supply power for con-struction work, will be ready as an auxiliary to pick upthe load when necessary. The complete equipment for the power and distributionsystem on the canal comprises the 7500 , 2200 volt hy-droelectric power plant at Gatun; the 4500 , 2200 voltCurtis turbo-generator electric power plant at Mirafloresfor emergency; a double 44,000 volt transmission line acrossthe Isthmus, connecting Cristobal and Balboa with the twopower plants; four 44,000*2200 volt substations, steppingdown at Cristobal and Balboa, and up or down at Gatunand Miraflores, depending on which of the two plants issupplying power; thirty-six 2200-240 volt transmission sta-tions for power, traction and light
