The high outside rim of the cup was about 2¼ miles round, with a diameter of 1,500 yards; and the circle was nearly as perfect as that of a cup. Down thence to the salt lake at the bottom the inside of the bowl fell steeply but gradually, and was thickly covered with bush. The perfect regularity of shape was, to the eye, the most wonderful feature of the phenomenon. At the bottom to which we descended lay the shallow salt lake, which at the time of our visit was about half full,--or half covered, I might better say, in describing the gently shelving bottom of which not more than a moiety was under water. In very dry weather there is no water at all,--and then no salt. When full the lake is about 400 yards across. Some enterprising Englishman had put up a large iron pan 36 feet by 20, and 18 inches deep, with a furnace under it, which, as everything had been brought out from England at a great cost for land transit, must have been an expensive operation. But it had been deserted because the late Government had been unable to protect him in the rights which he attempted to hire from them. The farmers of the neighbourhood would not allow themselves to be debarred from taking the salt,--and cared nothing for the facts that the Government claimed the privilege of disposing of the salt and that the Englishman had bought the privilege. The Englishman therefore withdrew, leaving behind him his iron pan and his furnace, no doubt with some bitter feelings. It is probable, I believe, that another Englishman,--or a Scotchman,--will now commence proceedings there, expecting that Downing Street will give better security than a Republican President. In the meantime our friend the Boer pays £50 per annum to the Government, and charges all comers some small fine per load for what they take. Baskets are inserted into the water and are pulled up full of slush. This is deposited on the shore and allowed to drain itself. On the residuum carbonate of soda rises, with a thick layer, as solid cream on standing milk;--and below this there is the salt more or less pure,--very nasty, tasting to me as though it were putrid,--but sufficing without other operation for the curing of meat and for the use of cattle. I was told by one of our party that the friable stone which we found all around is soda-feldspar from which, as it melts in the rain, the salt is brought down. Here, at this place, there is but one crater;--whereas at other places of a like nature, as in New Zealand and Central America, I have seen various mouths crowded together, like disjected fragments of a great aperture down into the earth. Here there is but the one circle, and that is as regular as though it had been the work of men’s hands.
