Setting To Work With Our Axes, We Soon Had A Raft Built, Lashing The Poles Together With The Fibre Which Grows In Abundance All Over The District.

When it was finished, we pushed it out of the little backwater where it had been constructed, and the young engineer jumped aboard.

All went well until it got out into midstream, when much to my amusement it promptly toppled gracefully over. I helped my friend to scramble quickly up the bank out of reach of possible crocodiles, when, none the worse for his ducking, he laughed as heartily as I at the adventure.

Except for an occasional relaxation of this sort, every moment of my time was fully occupied. Superintending the various works and a hundred other duties kept me busy all day long, while my evenings were given up to settling disputes among the coolies, hearing reports and complaints from the various jemadars and workpeople, and in studying the Swahili language. Preparations, too, for the principal piece of work in the district - the building of the railway bridge over the Tsavo river - were going on apace. These involved, much personal work on my part; cross and oblique sections of the river had to be taken, the rate of the current and the volume of water at flood, mean, and low levels had to be found, and all the necessary calculations made. These having at length been completed, I marked out the positions for the abutments and piers, and the work of sinking their foundations was begun. The two centre piers in particular caused a great deal of trouble, as the river broke in several times, and had to be dammed up and pumped dry again before work could be resumed. Then we found we had to sink much deeper than we expected in order to reach a solid foundation indeed, the sinking went on and on, until I began to despair of finding one and was about to resort to pile-driving, when at last, to my relief, we struck solid rock on which the huge foundation-stones could be laid with perfect safety.

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.
