This crossing is very unusual in the construction ofincline planes, and called for special construction, as itwas not permisible to use an open conduit, as vehiclesconstantly cross the line. A narrow conduit was there- THE LOWER TERMINUS. entangled in the moving cable as long as the ropesare exposed. The arrangement is clearly shown in theillustrations. Another novel device is the provision by which theconductor of each car is in constant communication withthe engineer by means of an electric signal wire whichwill be noticed in the illustration as extending along the
