The line of march towards the interior, which, after due consideration, we adopted, runs parallel to the routes known to us, by the writings of many travellers, but extends as far as thirty miles north of the most northerly of them. At Rosako the route began to diverge from that which led to Msuwa and Simba-Mwenni, and opened out on a stretch of beautiful park land, green as an English lawn, dipping into lovely vales, and rising into gentle ridges. Thin, shallow threads of water in furrow-like beds or in deep narrow ditches, which expose the sandstone strata on which the fat ochreous soil rests, run in mazy curves round forest clumps, or through jungle tangles, and wind about among the higher elevations, on their way towards the Wami river. _Nov. 23._—On the 23rd, we halted at the base of one of the three cones of Pongwé, at a village situated at an altitude of 900 feet above the sea. The lesser Pongwé cone rises about 800 feet higher than the village, and the greater probably 1200 feet. The pedometers marked forty-six miles from Bagamoyo. Congorido, a populous village, was reached on the 24th. From my hut, the Pongwé hills were in clear view. The stockade was newly built, and was a good defensive enclosure. The drinking-water was brackish, but after long search, something more potable was discovered a short distance to the south-east. Mfuteh, the next village, was another strong, newly enclosed construction after the pattern of the architecture of Unyamwezi. The baobab, at this height, began to flourish, and in the depressions of the land the doum, borassus, and fan-palm were very numerous. The soil westward of Congorido, I observed, contains considerable alkali, and it is probable that this substance is favourable to the growth of palms. The villagers are timid and suspicious. Lions are reported to abound towards the north. Westward of Mfuteh we travelled along the right or southern bank of the Wami for about four miles. Its banks are fringed with umbrageous wooded borders, and beyond these extends an interesting country. The colossal peak of Kidudu rears its lofty crown to a great height, and forms a conspicuous landmark, towering above its less sublime neighbours of Nguru, about fifteen or twenty miles north of the Wami’s course.
