THE MAN-EATERS OF TSAVO AND OTHER EAST AFRICAN ADVENTURES! Part 16

Another great difficulty with which we had to contend was the absence of suitable stone in the neighbourhood. 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. Brock and I were out “pot-hunting,” and hearing some guinea-fowl cackling among the bushes, I made a circuit half round them so that Brock, on getting in his shot, should drive them over in my direction. I eventually got into position on the edge of a deep ravine and knelt on one knee, crouching down among the ferns. There I had scarcely time to load when over flew a bird, which I missed badly; and I did not have another chance, for Brock had got to work, and being a first-rate shot had quickly bagged a brace. Meanwhile I felt the ground very hard under my knee, and on examination found that the bank of the ravine was formed of stone, which extended for some distance, and which was exactly the kind of material for which I had long been fruitlessly searching. I was greatly delighted with my unexpected discovery, though at first I had grave misgivings about the distance to be traversed and the difficulty of transporting the stone across the intervening country. 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.
