The only rivers of consequence beside the Sabia and the Buzi in this portion of Umzela's country are the Umkoni, Umswelise, Umtschomie, Gerongosi, the source of which rises not far from the Buzi, runs east, and enters the Indian Ocean, about twenty miles south of Sofala. The Lusuti rises with several branches about thirty miles to the north of Umzela's kraal, and joins the Buzi sixty miles from its mouth. There is also the Haroni and its tributary the Lusiti, and the small river Donde that flows into the Sofala harbour. South of the Mandanda region are the districts of Sheshonga, Indobolini, Mashelbe, and Makalingi. To the east is the Manklin district, that takes the coast-line from Maramone Bay, down south to Cape Lady Grey, off which are the islands of Bazaruta, Benguela, Sigin, and a small group at Cape St. Sebastian. To the north of Maramone Bay, some thirty miles, are the two great islands of Chuluwan. All the coast-line is flat, infested with the tsetse-fly, and most unhealthy. The Mandowa tribe occupy the hill district and country inland from Sofala, and it is under the rule of Umzela, and is in charge of Imbasugwar, one of his chief men. Manukuza, father of Umzela, is a Zulu from Zululand, who fled from Chaka, the great Zulu king. His followers are called Mongonis, and all the tribes under him, viz. Basigo, Kulu, Mandanda, Cholee, and Mandower, are called Tonges. Deloms, a chief of Umzela, is over the district of Mazibbe, and Sondaba, an Indian, over Sheshongi, which is on the south side of the Sabia. The country is flat and marshy, and full of game. Rhinoceros, elephants, koodoos, giraffes, wildebeest, wild hogs, and nearly all the antelope tribe, and zebras. Date and other palms, bananas, jute, and wild cotton, beside many native fruits abound. A very poisonous plant grows on the flats, from which the natives extract, from the seed, poison to put on their assagais and arrows. [This poison is the strongest known. An eminent toxicologist, who in distilling became inoculated with it through a slight scratch. He was nearly dying for six weeks, and said he had no idea that any poison could be so strong; it would kill a man in three minutes, and an elephant in one hour and a half. The flesh of animals killed by it is not poisonous. It loses its strength by evaporation in about a year.]
