They then filed off with a handsome present of cloth, delighted with the result of their visit; and the following morning they arrived with the tusk, which was a large one, weighing about 80 lbs. But we did not purchase it, explaining to them that we had only come there to see the country, and to hunt elephant for our own amusement, and that we were not like the Swahili traders whom they had met. We allowed them to bring the tusk, so that they might see that they could repose absolute confidence in us. With the tusk they brought several loads of sweet potatoes, and we gave them a present in exchange. The chief was a very pleasant and intelligent native, and during the next two days Sharp made several short trips with him. One day the chief and all his men showed us how they hunted antelope with dogs. The dogs were well trained; they rounded the beast and drove it within reach of the hunters, who succeeded in spearing it. The whole of the southern coast of the Albert Edward is the home of hundreds of hippopotami, and the beach is lined with masses of their dung; all night they kept up a tremendous concert of bellowing and grunts, which rendered sleep well-nigh impossible. My foot having meanwhile sufficiently healed to allow me to be carried, we advanced along the shore of the lake, and camped at the edge of the extensive swamp at the mouth of the three main streams which flow into the lake from the south-east. Here it was obvious that there had been a recent and abrupt rise in the country, the old lake-bed being sharply defined. From this point I perceived that my observations would materially diminish the area of the lake; the suggested coast-line on extant maps practically corresponds with the last lake level. Judging from the comparatively insignificant size of the vegetation on the recently-exposed lake-bed, the last rise and level must have been historically recent and quite sudden; in fact, a remarkable point was that this vegetation corresponds in age to the vegetation found on the lava-beds that had been poured out by the volcanoes immediately prior to the late terrific eruption. Owing to the swampy nature of the country, we were compelled to again march south-east; and after crossing a flat table-land, again descended on to the last level of the lake, where we crossed the first of the south-eastern streams, called the Sasa. Here an arm of the late lake level runs five miles inland, and is three miles broad. Then we again climbed on to the table-land, which is the last lake-level but two, and camped on the site of two deserted villages. Our blood-brother was still with us, and he informed us that these villages had been raided by a tribe from the east, and that the surviving inhabitants had retired to the impenetrable thorn-jungle, or had fled to the Rutchuru valley.
