The islands of Imyack and Elephant command the entrance of the outer bay, and the islands at the mouth of the Uncomasi or King George's river, Krocodil, and Sabia, that rise in the Transvaal south of Lydenburg, which has never been thoroughly explored. The coast-line from Delagoa Bay to Inhambane is likewise little-known, as also between that port and Sofala, and north to the Zambese river. The principal towns in the Portuguese possessions on the east coast are Lorenzo Marques, Inhambane, Sofala, and the two small river towns up the Zambese, Senna and Tette. Steamers occasionally touch at all the coast towns named, on their way to Zanzibar from Natal. Quilimane is situated on the north of the Zambese river, upon one of its branches, where a Portuguese governor resides for that district. Another Sabia flows into the ocean near Sofala. CHAPTER TWENTY SIX. A CURSORY GLANCE AT THOSE PORTS OF SOUTH AFRICA THAT OCCUPY THE EXTREME SOUTH OF THE AFRICAN CONTINENT, SOUTH OF SOUTH CENTRAL AFRICA. South of South Central Africa, which has comprised my field, of exploration, is the Colony of the Cape of Good Hope, which takes in the whole of the southern peninsula of the African continent, from the Orange river to Cape Agulhas, and extends towards the east as far as Natal. It is divided into the eastern and western provinces and Griqualand West. Cape Town is the seat of Government and the capital, and is governed by a High Commissioner and Governor, a Ministry and Legislative Council, and a House of Assembly, both elected. The Governor is appointed by the British Government. The principal ports are Table Bay at Cape Town, False Bay, including Simon's Town, and the naval station of the colony, Mossel Bay, Algoa Bay at Port Elizabeth, East London, and a few small bays along the coast. The principal rivers are the Orange, Caledon, Kraai, Zeekoe, Buffalo, draining Little Namaqualand, Olifant, Berg rivers draining the district of Malmesbury, Zout river draining Koeberg and neighbourhood. Easters river enters False Bay, Londerende river drains part of Swellendam and Worcester districts, Gawirtz and its tributaries drain the George, Worcester, and Beaufort districts, and several small streams up to Zwartkops, that enters the sea a few miles to the north-east of Port Elizabeth. Following up the coast are Samdays, Bushman, Kowie, Great Fish river, Kaga, Koonap, Kat, Keiskama, Buffalo, Great Kei, White Kei, Indwa, Tosmo (which drains the country round Queen's Town and part of Kaffraria), Bashee, Umtata, Umzimvobo, and Umzimcula; not one of them is navigable from the great fall they take in their course to the sea, and they have deep water in them only after heavy rains, which is the case with all the rivers in this colony.
