About half a ton can beput into each skip and a speed obtained of six miles an hour. The principle of the systemof telpherage is l)est shown forth in a commercial line that was put into operation at , to carry clay from a pit to the Glynde railway siding, whence it was delivered intotrucks and takenbv rail to its ultimate destination.
