The lively interest which has recently been felt in England for the discovery of the most southern sources of the Nile induced the Abyssinian traveller above referred to, (Charles Beke) at a recent meeting of the “British Association for the advancement of Science,” held at Swansea, more fully to develope his ideas respecting the connection between the Mountains of the Moon and those of Habesch. “The Abyssinian elevated plain,” he says, “generally above 8000 feet high, extends towards the south to nearly 9° or 10° north latitude. The eastern declivity of the highlands has, to the inhabitants of the coast, the appearance of a mountain chain. The plateau, which diminishes considerably in height towards its southern extremity, passes into the Mountains of the Moon, which run not east and west, but parallel to the coast, or from N.N.E. to S.S.W., extending from 10° north to 5° south latitude. The sources of the White Nile are situated in the Mono-Moezi country, probably in 2° 30′ south latitude, not far from where the river Sabaki, on the eastern side of the Mountains of the Moon, falls into the Indian Ocean, near Melindeh, north of Mombaza. Last autumn (1847), the two Abyssinian missionaries Rebmann and Dr. Krapf were still on the coast of Mombaza. They have established in the vicinity, among the Wakamba tribe, a missionary station, called Rabbay Empie, which seems likely to be very useful for geographical discoveries. Families of the Wakamba tribe have advanced westward five or six hundred miles into the interior of the country, as far as the upper course of the river Lusidji, the great lake Nyassi or Zambeze (5° south lat.?), and the vicinal sources of the Nile. The expedition to these sources, which Friedrich Bialloblotzky, of Hanover, is preparing to undertake” (by the advice of Beke), “is to start from Mombaza. The Nile coming from the west referred to by the ancients is probably the Bahr-el-Ghazal, or Keilah, which falls into the Nile in 9° north lat., above the mouth of the Godjeb or Sobat.”
