On our way from the house we went to see the cobalt mine, which is on a hillside a mile away. It has only been established about three years, and has existed hitherto under the greatest difficulties as regards labour, transport, machinery, danger from surrounding native tribes, &c.; but it has already, the proprietor informed me, reduced the price of cobalt--the blue dye used to colour such things as the willow-pattern plates--by one-half in the English market, bringing it down from somewhere about 140 pounds to 80 pounds a ton. We were very much astonished to see the amount of work which had been done, as we expected to find a pit such as the Kafirs work for copper, but instead of that there was a large slanting shaft quite a hundred yards long, to say nothing of various openings out of it following branch leads of ore. There is also a vertical shaft one hundred feet deep, through which the ore comes up, and by which one can ascend and descend in a bucket. After we emerged from this awful hole, we went into another, a drive running straight into the mountain for more than three hundred feet, following a vein of black oxide of cobalt, which is much more valuable than the ore; and, though the vein is rarely more than a foot in thickness, pays very well. Leaving the mine, we rode on past some old Kafir copper-workings--circular pits--which must have been abandoned, to judge from their appearance, a hundred years ago, till we came to the banks of the great “Olifants’” or “Elephants’” river. This magnificent stream, though it is unnavigable owing to frequent rapids, has stretches miles long, down which a man-of-war could steam, and after its junction with the Elands’ River it grows larger and larger till, pursuing a north-east course, it at length falls into the mighty Limpopo. It is a very majestic but somewhat sluggish stream, and its water is not very good. You cannot see the river till you are right upon it, owing to the great trees with which its steep banks are fringed, and in the early morning it is quite hidden from bank to bank by a dense mass of billows of white mist, indescribably strange to look upon.
But, beautiful as this country is, it is most unhealthy for man and beast. The close odour, the long creeping lines of mist, the rich rank vegetation, the steady heat of day and night, all say one word, “fever,” and fever of the most virulent type. The traveller through this sort of country is conscious of a latent fear lest he should some day begin to feel hot when he ought to be cold, and cold when he ought to be hot, and so be stricken down, to rise prematurely old, or perhaps to die, and be buried in a lonely grave covered with stones to keep off the jackals. We were travelling in the very worst fever-month, March, when the summer vegetation is commencing to rot, and throw off its poisonous steam. What saved us here and afterwards, at Secocoeni’s, was our temperate living, hard exercise, and plenty of quinine and tobacco-smoke.
