From what has already been discovered of its richness, we see plainly the ancients, who extracted the gold, have only done so to a limited extent--what may be termed surface workings; for their numerous pits, after all, are mere scratches in the ground at places, but when they are properly worked and greater depth attained, the mines may be found almost inexhaustible. And if the gold-dust, found in the sand of the rivers, can be procured by a few single washings from a small dish, what may be expected when the whole of these rivers have been properly worked? CHAPTER TWENTY FOUR. THE PHYSICAL GEOGRAPHICAL FEATURES OF THAT REGION, LYING BETWEEN THE MATABELE AND MASHONA COUNTRY, AND THE INDIAN OCEAN, NOW UNDER THE RULE OF THE CHIEF UMZELA AND OTHER CHIEFS. This extensive portion of South Central Africa abuts on the north-east boundary of the Transvaal, the eastern boundary of the Mashona and Matabeleland, and the Zambese in the north, up to 29 degrees 50 minutes East longitude. On the east by the Indian Ocean, and on the south by the Portuguese possessions at Delagoa Bay. The main watershed passing through the Mashona country, which divides the Limpopo from the Zambese river, in 18 degrees 10 minutes South latitude, turns east and separates the waters flowing into the Zambese, through the Mazoe river, from that which flows into the Sabia, runs south down to 21 degrees 10 minutes South latitude, 32 degrees 5 minutes East longitude, when it turns easterly and north-east, and enters the south side of Sofala Bay. This river has many tributaries on the west, draining a portion of the Mashona country, but on the eastern bank there are few, and those but small. The most important river is the Buzi, taking its rise from many small tributaries in a hilly district, to the east of the Sabia in 20 degrees 30 minutes South latitude, 32 degrees 30 minutes East longitude, on a tributary of which the Umsweleze, the chief Umzela's kraal, is situated; the Buzi from this point takes a sweep round in a north-east direction, and enters the Indian Ocean in 19 degrees 50 minutes South latitude, passing through the Sofala region, between this latter river and the Sabia. The Garogesi river enters Sofala Bay.
