The next day, as we had no further need of our Beluch escort, a halt was made to enable me to draw up a "Progress Report," and pack all the specimens of natural history collected on the way, for the Royal Geographical Society. Captain Grant, taking advantage of the spare time, killed for the larder two buck antelopes, and the Tots brought in, in high excited triumph, a famous pig. This march, which declines from the Kingani a little, leads through rolling, jungly ground, full of game, to the tributary stream Mgeta. It is fordable in the dry season, but has to be bridged by throwing a tree across it in the wet one. Rising in the Usagara hills to the west of the hog-backed Mkambaku, this branch intersects the province of Ukhutu in the centre, and circles round until it unites with the Kingani about four miles north of the ford. Where the Kingani itself rises, I never could find out; though I have heard that its sources lies in a gurgling spring on the eastern face of the Mkambaku, by which account the Mgeta is made the longer branch of the two.

Under U-Sagara, or, as it might be interpreted, U-sa-Gara--country of Gara--is included all the country lying between the bifurcation of the Kingani and Mgeta rivers east, and Ugogo, the first country on the interior plateau west,--a distance of a hundred miles. On the north it is bounded by the Mukondokua, or upper course of the Wami river and on the south by the Ruaha, or northern great branch of the Lufiji river. It forms a link of the great East Coast Range; but though it is generally comprehended under the single name Usagara, many sub-tribes occupy and apply their own names to portions of it; as, for instance, the people on whose ground we now stood at the foot of the hills, are Wa-Khutu, and their possessions consequently are U-Khutu, which is by far the best producing land hitherto alluded to since leaving the sea-coast line. Our ascent by the river, though quite imperceptible to the eye, has been 500 feet. From this level the range before us rises in some places to 5000 to 6000 feet, not as one grand mountain, but in two detached lines, lying at an angle of 45 degrees from N.E. to S.W., and separated one from the other by elevated valleys, tables, and crab-claw spurs of hill which incline towards the flanking rivers. The whole having been thrown up by volcanic action, is based on a strong foundation of granite and other igneous rocks, which are exposed in many places in the shape of massive blocks; otherwise the hill-range is covered in the upper part with sandstone, and in the bottoms with alluvial clay. This is the superficial configuration of the land as it strikes the eye; but, knowing the elevation of the interior plateau to be only 2500 feet above
