The Limpopo is an unfortunate river as much of its valley with a considerable district on each side of it is subjected by nature to an abominable curse,--which population and cultivation will in the course of years probably remove but which at present is almost fatal to European efforts at work within the region affected. There is a fly,--called the Tsetse fly,--which destroys all horses and cattle which come within the regions which it selects for its own purposes. Why it should be destructive to a party of horses or to a team of oxen and not to men has I believe to be yet found out. But as men cannot carry themselves and their tools into these districts without horses or oxen, the evil is almost overpowering. The courses of the fly are so well known as to have, enabled geographers to mark out on the maps the limits of the Tsetse country. The valley of the Limpopo river may be taken as giving a general idea of the district so afflicted, the distance of the fly-invested region varying from half a dozen to 60 and 80 miles from the river. But towards the East it runs down across the Portuguese possessions never quite touching the sea but just reaching Zululand. Tatin is to the north west of this region, and though the place itself is not within the fly boundary, all ingress and egress must have been much impeded by the nuisance. The first discovery there of gold is said to have been made by Mauch. There has been heavy work carried on in the district and a quartz-crushing machine was used there. When I was in the Transvaal these works had been abandoned, but of the existence of gold in the country around there can be no doubt. In 1868 the same explorer, Mauch, found gold at a spot considerably to the south east of this,--south of the Limpopo and the Tsetse district, just north of the Olifant’s river and in the Transvaal. Then in 1871 Mr. Button found gold at Marabas Stad, not far to the west of Mauch’s discovery, in the neighbourhood of which the mines at Eesteling are now being worked by an English Company. On the Marabas-Stad gold fields a printed report was made by Captain Elton in 1872, and a considerable sum of money must have been spent. The Eesteling reef is the only one at present worked in the neighbourhood. Captain Elton’s report seems to promise much on the condition that a sufficient sum of money be raised to enable the district to be thoroughly “prospected” by an able body of fifty gold-miners for a period of six months. Captain Elton no doubt understood his subject, but the adequate means for the search suggested by him have not yet been raised. And, indeed, it is not thus that gold fields have been opened. The chances of success are too small for men in cold blood to subscribe money at a distance. The work has to be done by the gambling energy of men who rush to the spot trusting that they may individually grasp the gold, fill their pockets with the gold, and thus
