The next day we reached the village of Parkani. For several days past our guides had told us that we were very near to the lake, and we were now assured that we should reach it on the morrow. I had noticed a lofty range of mountains at an immense distance west, and I had imagined that the lake lay on the other side of this chain; but I was now informed that those mountains formed the western frontier of the M'wootan N'zige, and that the lake was actually within a day's march of Parkani. I could not believe it possible that we were so near the object of our search. The guide Rabonga now appeared, and declared that if we started early on the following morning we should be able to wash in the lake by noon! That night I hardly slept. For years I had striven to reach the "sources of the Nile." In my nightly dreams during that arduous voyage I had always failed, but after so much hard work and perseverance the cup was at my very lips, and I was to DRINK at the mysterious fountain before another sun should set--at that great reservoir of nature that ever since creation had baffled all discovery. I had hoped, and prayed, and striven through all kinds of difficulties, in sickness, starvation, and fatigue, to reach that hidden source; and when it had appeared impossible we had both determined to die upon the road rather than return defeated. Was it possible that it was so near, and that to-morrow we could say, "The work is accomplished"? The sun had not risen when I was spurring my ox after the guide, who, having been promised a double handful of beads on arrival at the lake, had caught the enthusiasm of the moment. The day broke beautifully clear, and having crossed a deep valley between the hills, we toiled up the opposite slope. I hurried to the summit. The glory of our prize burst suddenly upon me! There, like a sea of quicksilver, lay far beneath the grand expanse of water--a boundless sea horizon on the south and south-west, glittering in the noonday sun; and in the west, at fifty or sixty miles' distance, blue mountains rose from the bosom of the lake to a height of about 7000 feet above its level.
