The other rivers in the northern division, and within the Limpopo basin, are the Crocodile, with its many tributaries, rising in the Drakensberg or Quathlamba range, and, passing through the Lobombo mountain, receives the Umcomasi, Sabie, and other small streams, and enters the northern part of Delagoa Bay. The Umbelosi drains the country south of the Komati, and passing through the Lobombo range, enters Delagoa Bay, or inner harbour at Lozrenzo Marques; it is navigable from the bay some few miles from its mouth. South of this river is the Tembe, which rising in the Lobombo mountains, with its small tributaries, enters the inner harbour. The last of the rivers that drain the south-eastern portion of the Transvaal is the important Maputa or Usutu river, which rises in the New Scotland district, at an altitude of 5780 feet above sea-level, receiving the following tributaries--Impeloosi, Little Usutu, Umkompies, Umkonto, Umtaloos, and other small streams; flowing through the Lobombo it receives the Pongola river, which rises a few miles to the east of Wakkerstroom, and receiving (in its course down) many tributaries flowing east and north, joins the Usutu, where it turns in a north-east and north direction for fifty miles; when a broad and navigable river it enters the southern part of Delagoa Bay. The lower portion for twenty miles passes through the Portuguese possessions, and after crossing the Lobombo mountains, it leaves the Transvaal and Amaswasiland, and enters the northern part of Zululand or Amatonga country. This completes the river system on the east of the Limpopo basin. On the west there are a few branches of the Limpopo on the left bank, that will complete this western division, viz. the Great and Little Marico rivers, the Molmane, the upper portion of the Notuane, and the Franks and Elands rivers, that drain the Marico and Rustenburg districts; the Orange and Vaal river basin, which is separated from the Limpopo by the central watershed, already described, which is also called the Hooge or High Veldt. The Vaal river rises in the Quathlambe mountains on the eastern border of the Transvaal, called the New Scotland district, at an altitude of 5813 feet, near Lake Crissie, flowing south-west past the town of Stamlerton, which is on the main transport road from Natal to Pretoria, passing through an open country, receiving in its course many small feeders; from this town the river turns westerly to Klip river, which is the boundary between the Orange Free State and the Transvaal. From this point the Vaal forms the boundary between the two Republics, down to Griqualand West, taking many turns and twists in a westerly, then south-westerly direction, receiving in its course many streams on the right bank, within the Transvaal boundary, as under--Klip, Gans, Sand, Bushman, Kapok, Rand, Waterfal, Klite, Kalk, Eland, Ensel, all spruits, to the Moi river, upon which Potchefstroom is built.
