“ It was not that there was none to be found, for the whole district abounds in rock, but that it was so intensely hard as to be almost impossible to work, and a bridge built of it would have been very costly. I spent many a weary day trudging through the thorny wilderness vainly searching for suitable material, and was beginning to think that we should be forced to use iron columns for the piers, when one day I stumbled quite by accident on the very thing. ”

“ Indeed, I found in the end that the only way of getting the material to the place where it was wanted was by laying down a tram line right along the ravine, throwing a temporary bridge across the Tsavo, following the stream down and re-crossing it again close to the site of the permanent bridge. Accordingly, I set men to work at once to cut down the jungle and prepare a road on which to lay the double trolley line. ”

“ Presently we came to the sharp incline which led to the log bridge over the river. Here it was the custom of the men, instead of running beside the trolley, to step on to it and to let its own momentum take it down the slope, moderating its speed when necessary by a brake in the shape of a pole, which one of them carried and by which the wheels could be locked. On this occasion, however, the pole was by some accident dropped overboard, and down the hill we flew without brake of any kind. Near the bridge there was a sharp curve in the line, where I was afraid the trolley would jump the rails ”
