When we left the Mokoko, Ramotobi seemed, for the first time, to be at a loss as to which direction to take. He had passed only once away to the west of the Mokoko, the scenes of his boyhood. Mr. Oswell, while riding in front of the wagons, happened to spy a Bushwoman running away in a bent position, in order to escape observation. Thinking it to be a lion, he galloped up to her. She thought herself captured, and began to deliver up her poor little property, consisting of a few traps made of cords; but, when I explained that we only wanted water, and would pay her if she led us to it, she consented to conduct us to a spring. It was then late in the afternoon, but she walked briskly before our horses for eight miles, and showed us the water of Nchokotsa. After leading us to the water, she wished to go away home, if indeed she had any--she had fled from a party of her countrymen, and was now living far from all others with her husband--but as it was now dark, we wished her to remain. As she believed herself still a captive, we thought she might slip away by night; so, in order that she should not go away with the impression that we were dishonest, we gave her a piece of meat and a good large bunch of beads; at the sight of the latter she burst into a merry laugh, and remained without suspicion.
At Nchokotsa we came upon the first of a great number of salt-pans, covered with an efflorescence of lime, probably the nitrate. A thick belt of mopane-trees (a 'Bauhinia') hides this salt-pan, which is twenty miles in circumference, entirely from the view of a person coming from the southeast; and, at the time the pan burst upon our view, the setting sun was casting a beautiful blue haze over the white incrustations, making the whole look exactly like a lake. Oswell threw his hat up in the air at the sight, and shouted out a huzza which made the poor Bushwoman and the Bakwains think him mad. I was a little behind him, and was as completely deceived by it as he; but, as we had agreed to allow each other to behold the lake at the same instant, I felt a little chagrined that he had, unintentionally, got the first glance. We had no idea that the long-looked-for lake was still more than three hundred miles distant. One reason of our mistake was, that the River Zouga was often spoken of by the same name as the lake, viz., Noka ea Batletli ("River of the Batletli").
The mirage on these salinas was marvelous. It is never, I believe, seen in perfection, except over such saline incrustations. Here not a particle of imagination was necessary for realizing the exact picture of large collections of water; the waves danced along above, and the shadows of the trees were vividly reflected beneath the surface in such an admirable manner, that the loose cattle, whose thirst had not been slaked sufficiently by the very brackish water of Nchokotsa, with the horses, dogs, and even the Hottentots ran off toward the deceitful pools. A herd of zebras in the mirage looked so exactly like elephants that Oswell began to saddle a horse in order to hunt them; but a sort of break in the haze dispelled the illusion. Looking to the west and northwest from Nchokotsa, we could see columns of black smoke, exactly like those from a steam-engine, rising to the clouds, and were assured that these arose from the burning reeds of the Noka ea Batletli.
On the 4th of July we went forward on horseback toward what we supposed to be the lake, and again and again did we seem to see it; but at last we came to the veritable water of the Zouga, and found it to be a river running to the N.E. A village of Bakurutse lay on the opposite bank; these live among Batletli, a tribe having a click in their language, and who were found by Sebituane to possess large herds of the great horned cattle. They seem allied to the Hottentot family. Mr. Oswell, in trying to cross the river, got his horse bogged in the swampy bank. Two Bakwains and I managed to get over by wading beside a fishing-weir. The people were friendly, and informed us that this water came out of the Ngami. This news gladdened all our hearts, for we now felt certain of reaching our goal. We might, they said, be a moon on the way; but we had the River Zouga at our feet, and by following it we should at last reach the broad water.
