This is geared totwo cable driving drums. Each cable is endless and hastwo cars attached to it. Each car thus has two UP MT. VESUVIUS BY CABLE. ^tied/lf^aiWay-J^ylcW The tension carriages for the cables are held by weightssuspended over a pulley. Wooden supporting pulleysare set every 50 feet along the line. The cable speed is6j^ feet per second. The cars with a load of ten pas-sengers weigh about three tons. For safety, two inde-pendent ropes are laid and the cars have automaticgrips and hand brakes. The ropes are iy\ inches indiameter, rated at a braking strain of 32 tons. Theywere furnished by Felten «& Guigleaunie, Germany, andthe Warrington Wire Rope Works, Liverpool. Thecost of the entire work was $125,000. SOLID VS. SPLIT GEARS.
