A four hours' march, on the 12th of October, brought us to a nullah similar to the Gombe, which, during the wet season, flows to the Gombe River, and thence into the Malagarazi River. A little before camping we saw a herd of nimba, or pallah; I had the good fortune to shoot one, which was a welcome addition to our fast diminishing store of dried meats, prepared in our camp on the Gombe. By the quantity of bois de vaches, we judged buffaloes were plentiful here, as well as elephant and rhinoceros. The feathered species were well represented by ibis, fish-eagles, pelicans, storks, cranes, several snowy spoon-bills, and flamingoes. From the nullah, or mtoni, we proceeded to Mwaru, the principal village of the district of Mwaru, the chief of which is Ka-mirambo. Our march lay over desolated clearings once occupied by Ka-mirambo's people, but who were driven away by Mkasiwa some ten years ago, during his warfare against Manwa Sera. Niongo, the brother of the latter, now waging war against Mbogo, had passed through Mwaru the day before we arrived, after being defeated by his enemy. The hilly ridge that bounded the westward horizon, visible from Utende, was surmounted on this day. The western slope trends south-west, and is drained by the River Mrera, which empties into the Malagarazi River. We perceived the influence of the Tanganika, even here, though we were yet twelve or fifteen marches from the lake. The jungles increased in density, and the grasses became enormously tall; these points reminded us of the maritime districts of Ukwere and Ukami. We heard from a caravan at this place, just come from Ufipa, that a white man was reported to be in "Urua," whom I supposed to mean Livingstone. Upon leaving Mwaru we entered the district of Mrera, a chief who once possessed great power and influence over this region. Wars, however, have limited his possessions to three or four villages snugly embosomed within a jungle, whose outer rim is so dense that it serves like a stone wall to repel invaders. There were nine bleached skulls, stuck on the top of as many poles, before the principal gate of entrance, which told us of existing feuds between the Wakonongo and the Wazavira. This latter tribe dwelt in a country a few marches west of us; whose territory we should have to avoid, unless we sought another opportunity to distinguish ourselves in battle with the natives. The Wazavira, we were told by the Wakonongo of Mrera, were enemies to all Wangwana.
