Mohammed guided us to perfection; the chain was crossed on the second day by the pass of Kidomma at an altitude of more than 6000 feet, and on the evening of the third day, after a very tiring march, we reached the point where the track leaves the plateau to go down into the bottom of the Modra valley. We got down a first drop of some 60 yards without very much trouble, in spite of the quarters of sharp-edged rock that rolled under the hesitating feet of our camels. Then, after perhaps a third of a mile of almost level going, I suddenly came in sight of the palm plantation of Modra lying at the bottom of a dark narrow gorge deep sunken between two almost vertical walls more than 1500 feet high. I was not without uneasiness at this sight, and came within a very little of thinking that the worthy Mohammed had deliberately lured me into some trap when he had said to me: “The descent into the Modra valley is rather difficult, but good camels can get down.” The descent into the valley of Yebbi, which I had found so arduous eleven days previously, seemed to me now quite a reasonable sort of descent compared with this one. Already the valley was echoing with the reports of rifles; here and there I saw Toubous climbing the cliff-sides like goats and stopping now and then to favour us from afar with noisy but harmless shots, and vigorous volleys of bad language more harmless still. There being no conceivable alternative to consider we had to go forward. Covered by an advanced guard that returned the Toubous’ fire with a fusillade of doubtful efficacy, and by a rear-guard that watched the points from which the rebels could have rolled down tons of rock on our heads, we crawled downwards in a circumspect advance along a path that was no path—that clung to the face of a steep cliff, now plunging sharply downwards in short zigzags, now hanging, a narrow ledge, above the abyss towards which great stones dislodged by our camels rolled rumbling or leapt clattering down from tier to tier. The camels were frightened; they had to be led forward one by one, and could only be got round corners with many stripes and voluble cursing. A little group of men went ahead of them, thrusting aside the most awkward blocks, and, where the natural steps in the rock were too steep, laying flat stones at the foot so as to break them in two. The descent was so toilsome and so slow that at sunset we were only halfway down. I had to call a halt, profiting by a little rocky spur that afforded us a narrow rugged platform where we found just room enough to make our camels kneel and to install our bivouac. The firing had almost ceased: our advanced guard came in soon afterwards after forcing the rebels to abandon their villages, the conical roofs of which could be seen shining in the moonlight more that 400 feet below. Still further down, below the palms, ran an invisible stream, forming a monotonous waterfall that we heard murmur in the neighbouring rocks.
