Each car is operated by two endless cables,one being placed on each side of the car. To each cable isattached a forked gripping device, held in position by springs,and connected with an automatic brake, which consists of twocogged eccentrics embracing the wooden stringer, and designedto hold the car in position in case the cable breaks or loses itstension. The cables are operated through gearing by a 40-hpsteam engine, which is located at the lower end of the line,. JiCILDlNG THE SUPPORTING WALL BENEATH THE TERRACEOF THE OBSERVATORY to minimize the danger from eruptions. The trip on this linetakes about 8 minutes. This line has been in use since 1879,and during that time the roadbed has gradually sunk, so thatwhenever there is a severe wind storm loose ashes accumulateto such an extent that it often takes 100 men or more severaldays to remove the debris, and thereby allow the service to beresumed. 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,
