Though out of Urimi at last, yet Stanley found the natives of Iramba a very little improvement on those of the former district. Mirambo was their terror, and hence they were suspicious of all strangers. Again and again he was mistaken for this terrible chieftain, and narrowly escaped being attacked. In fact, this formidable warrior was fighting at one time within a day's march of him. Urukuma was the next district he entered after Iramba, and he found it thickly peopled and rich in cattle. It consisted for the most part of rolling plains, with scattered chains of jagged hills. He was on the slope that led to the Nyanza, and the descent was so gradual, that he expected to find the lake, whose exploration he designed to make thorough and complete, comparatively shallow, although it covered a vast area. At last he reached a little village, not a hundred yards from the shore, and encamped. At this point he describes the topography of the new country he had passed over. He says: "As far as Western Ugogo I may pass over without attempting to describe the country, as readers may obtain a detailed account of it from 'How I Found Livingstone.' Thence north is a new country to all, and a brief description of it may be interesting to students of African geography. "North of Mizanza a level plain extends as far as the frontier of Urandawi, a distance of thirty-five miles (English). At Mukondoku the altitude, as indicated by two first-rate aneroids, was two thousand, eight hundred feet. At Mtiwi, twenty miles north, the altitude was two thousand eight hundred and twenty-five feet. Diverging west and north-west, we ascend the slope of a lengthy mountain-wall, apparently, but which, upon arriving at the summit, we ascertain to be a wide plateau covered with forests. This plateau has an altitude of three thousand eight hundred feet at its eastern extremity; but, as it extends westward it rises to a height of four thousand five hundred feet. It embraces all Uyanzi, Unyanyembe, Usukuma, Urimi and Iramba--in short, all that part of Central Africa lying between the valley of the Rufiji south and the Victoria Nyanza north, and the mean altitude of this broad upland cannot exceed four thousand five hundred feet. From Mizanza to the Nyanza is a distance of nearly three hundred geographical miles; yet, at no part of this long journey did the aneroids indicate a higher altitude than five thousand one hundred feet above the sea. "As far as Urimi, from the eastern edge of the plateau, the land is covered with a dense jungle of acacias, which, by its density, strangles all other species of vegetation. Here and there, only in the cleft of a rock, a giant euphorbia may be seen, sole lord of its sterile domain. The soil is shallow, and consists of vegetable mould, mixed largely with sand and detritus of the bare rocks, which crown each knoll and ridge, and which testify too plainly to the violence of the periodical rains.
