Everything that Demestre urged in support of his project was so just and clear that it was unanimously adopted without debate; in fact, everyone secretly wondered why he had not himself thought of it long before. The only thing to do now, therefore, was to trace the route of the future railway. In the first place, there was the old route through Kikuyu into Masailand, thence to the east of Kilimanjaro, past Taveta and Teita, to Mombasa. A second and possibly more favourable route was thought of, which led also southwards, and reached the coast at Mombasa, but took a direction two degrees further east, through Kikuyu, into the country of the Ukumbani, and thence followed the valley of the Athi river to Teita. This track might probably shorten the distance by more than a hundred miles. The third, the shortest route to the ocean, led directly east, following the Dana, through the Galla lands, to the Witu coast; here eventually nearly half the distance might be saved, for we were but about 280 miles from the coast in a straight line. It was decided that these three routes should be examined as carefully as would be possible in the course of a few months; for the beginning of the construction of the line was not to be delayed more than half a year. Demestre was appointed to examine the old route, with which he was already well acquainted. Two other skilful engineers were sent to the Athi and the Dana respectively, each accompanied, as was Demestre, by a staff of not less qualified colleagues. But these two latter expeditions, having to explore utterly unknown districts, inhabited by probably hostile tribes, had to be well armed. They were each 300 strong, and, besides a sufficient number of repeating-rifles, they took with them several war elephants, some cannons, and some rockets. All these expeditions were accompanied by a small band of naturalists, geologists in particular. They started in the beginning of May, and they were instructed to return, if possible, in August, before the short rainy season.
