This has caused the maintenance charges to be veryhigh, and plans have been made for the building of another cable line. The new cable line is to be built about 10 ft. (3 m)above the grade of the present line. It will be of meter gage,and the rails will have conical heads to allow the use of specialemergency brakes. The roadbed will be of dried mortar con-struction and the tiles laid in cement. Massive mortar pillars,. GROUP OF OFFICIALS AND ENGINEERS ON AN INSPECTION TOUR several meters wide, will be erected at intervals of about 65ft. (20 m). The new cars will seat twenty passengers, twice asmany as the old ones. The cable will be driven by a 550-volt,600-r. p. m. direct-current motor, which will be completelyinclosed to protect it from injurious gases and lava dust.
