Issuing out of the first series of cornfields, we heard the war-cries of the valley natives, and comprehended that they were taking position in favourable localities--the hill natives warning and guiding them. It was now near 4 P.M., a time to pick out camp, to make ready for the night in the midst of a population overwhelming in its numbers. Fortunately, close at hand rose the steep hill of Nzera-Kum with a spur, whose level top rose a hundred feet above the general face of the valley. It stood like an islet in the valley, distant from the river 500 yards, and from the base of Mazamboni's range 200 yards. From the crest of Nzera-Kum we could command a view east and west of all the northern face of the high range, and away over the summit lines of the horse-shoe ridge, across the Ituri branch. Fifty rifles could hold a camp on such a position against a thousand. We hurried up towards it, the warriors on the range slopes converging downward as if divining our intentions; a mass of noisy belligerents hastening towards the line of march from the river banks. The scouts in the advance fired a few solitary shots to clear the front, and we succeeded in reaching the islet hill and scrambled up. The loads were thrown down, a few picked skirmishers were ordered to either flank of the column to assist the rear-guard, others were directed to form a zeriba around the crown of the spur; a body of thirty men was sent to secure water from the river. In half an hour the column was safe on the hill, the zeriba was near completion, there was water for the thirsty, and we had a few minutes to draw breath and to observe from our commanding elevation what were our surroundings. The bird's-eye view was not a bit encouraging. About fifty villages were sprinkled through the valley; plantation after plantation, field after field, village after village met our vision in every direction. What lay on the mountains we did not know. The swarms of lusty-voiced natives on the slopes now numbered over 800. The air seemed filled with the uproar of the shouts.
