upper supply ceases to run and the rest becomes evaporated. The higher parts of its bed even are much broader and more capacious than the lower toward Kumadau. The water is not absorbed so much as lost in filling up an empty channel, from which it is to be removed by the air and sun. There is, I am convinced, no such thing in the country as a river running into sand and becoming lost. The phenomenon, so convenient for geographers, haunted my fancy for years; but I have failed in discovering any thing except a most insignificant approach to it.
My chief object in coming to the lake was to visit Sebituane, the great chief of the Makololo, who was reported to live some two hundred miles beyond. We had now come to a half-tribe of the Bamangwato, called Batauana. Their chief was a young man named Lechulatebe. Sebituane had conquered his father Moremi, and Lechulatebe received part of his education while a captive among the Bayeiye. His uncle, a sensible man, ransomed him; and, having collected a number of families together, abdicated the chieftainship in favor of his nephew. As Lechulatebe had just come into power, he imagined that the proper way of showing his abilities was to act directly contrary to every thing that his uncle advised. When we came, the uncle recommended him to treat us handsomely, therefore the hopeful youth presented us with a goat only. It ought to have been an ox. So I proposed to my companions to loose the animal and let him go, as a hint to his master. They, however, did not wish to insult him. I, being more of a native, and familiar with their customs, knew that this shabby present was an insult to us. We wished to purchase some goats or oxen; Lechulatebe offered us elephants' tusks. "No, we can not eat these; we want something to fill our stomachs." "Neither can I; but I hear you white men are all very fond of these bones, so I offer them; I want to put the goats into my own stomach." A trader, who accompanied us, was then purchasing ivory at the rate of ten good large tusks for a musket worth thirteen shillings. They were called "bones"; and I myself saw eight instances in which the tusks had been left to rot with the other bones where the elephant fell. The Batauana never had a chance of a market before; but, in less than two years after our discovery, not a man of them could be found who was not keenly alive to the great value of the article.
On the day after our arrival at the lake, I applied to Lechulatebe for guides to Sebituane. As he was much afraid of that chief, he objected, fearing lest other white men should go thither also, and give Sebituane guns; whereas, if the traders came to him alone, the possession of fire-arms would give him such a superiority that Sebituane would be afraid of him. It was in vain to explain that I would inculcate peace between them—that Sebituane had been a father to him and Sechele, and was as anxious to see me as he, Lechulatebe, had been. He offered to give me as much ivory as I needed without going to that chief; but when I refused to take any, he unwillingly consented to give me guides. Next day, however, when Oswell and I were prepared to start, with the horses only, we received a senseless refusal; and like Sekomi, who had thrown obstacles in our way, he sent men to the Bayeiye with orders to refuse us a passage across the river. Trying hard to form a raft at a narrow part, I worked many hours in the water; but the dry wood was so worm-eaten it would not bear the weight of a single person. I was not then aware of the number of alligators which exist in the Zouga, and never think of my labor in the water without feeling thankful that I escaped their jaws. The season was now far advanced; and as Mr. Oswell, with his wonted generous feelings, volunteered, on the spot, to go down to the Cape and bring up a boat, we resolved to make our way south again.
Coming down the Zouga, we had now time to look at its banks. These are very beautiful, resembling closely many parts of the River Clyde above Glasgow. The formation is soft calcareous tufa, such as forms the bottom of all this basin. The banks are perpendicular on the side to which the water swings, and sloping and grassy on the other. The slopes are selected for the pitfalls designed by the Bayeiye to entrap the animals as they come to drink. These are about seven or eight feet deep, three or four feet wide at the mouth, and gradually decrease till they are only about a foot wide at the bottom. The mouth is an oblong square (the only square thing made by the Bechuanas, for every thing else is round), and the long diameter at the surface is about equal to the depth. The decreasing width toward the bottom is intended to make the animal wedge himself more firmly in by his weight and struggles. The pitfalls are usually in pairs, with a wall a foot thick left uncut between the ends of each, so that if the beast, when it feels its fore legs descending, should try to save itself from going in altogether by striding the hind legs, he would spring forward and leap into the second with a force which insures the fall of his whole body into the trap. They are covered with great care. All the excavated earth is removed to a distance, so as not to excite suspicion in the minds of the animals. Reeds and grass are laid across the top; above this the sand is thrown, and watered so as to appear exactly like the rest of the spot. Some of our party plumped into these pitfalls more than once, even when in search of them, in order to open them to prevent the loss of our cattle. If an ox sees a hole, he carefully avoids it; and old elephants have been known to precede the herd and whisk off the coverings of the pitfalls on each side all the way down to the water. We have known instances in which the old among these sagacious animals have actually lifted the young out of the trap.
The trees which adorn the banks are magnificent. Two enormous baobabs ('Adansonia digitata'), or mowanas, grow near its confluence with the lake where we took the observations for the latitude (20d 20' S.). We were unable to ascertain the longitude of the lake, as our watches were useless; it may be between 22 Deg. and 23 Deg. E. The largest of the two baobabs was 76 feet in girth. The palmyra appears here and there among trees not met with in the south. The mokuchong, or moshoma, bears an edible fruit of indifferent quality, but the tree itself would be a fine specimen of arboreal beauty in any part of the world. The trunk is often converted into canoes. The motsouri, which bears a pink plum containing a pleasant acid juice, resembles an orange-tree in its dark evergreen foliage, and a cypress in its form. It was now winter-time, and we saw nothing of the flora. The plants and bushes were dry; but wild indigo abounded, as indeed it does over large tracts of Africa. It is called mohetolo, or the "changer", by the boys, who dye their ornaments of straw with the juice. There are two kinds of cotton in the country, and the Mashona, who convert it into cloth, dye it blue with this plant.
We found the elephants in prodigious numbers on the southern bank. They come to drink by night, and after having slaked their thirst—in doing which they throw large quantities of water over themselves, and are heard, while enjoying the refreshment, screaming with delight—they evince their horror of pitfalls by setting off in a straight line to the desert, and never diverge till they are eight or ten miles off. They are smaller here than in the countries farther south. At the Limpopo, for instance, they are upward of twelve feet high; here, only eleven: farther north we shall find them nine feet only. The koodoo, or tolo, seemed smaller, too, than those we had been accustomed to see. We saw specimens of the kuabaoba, or straight-horned rhinoceros ('R. Oswellii'), which is a variety of the white ('R. simus'); and we found that, from the horn being projected downward, it did not obstruct the line of vision, so that this species is able to be much more wary than its neighbors.
We discovered an entirely new species of antelope, called leche or lechwi. It is a beautiful water-antelope of a light brownish-yellow color. Its horns—exactly like those of the 'Aigoceros ellipsiprimnus', the waterbuck, or tumogo, of the Bechuanas—rise from the head with a slight bend backward, then curve forward at the points. The chest, belly, and orbits are nearly white, the front of the legs and ankles deep brown. From the horns, along the nape to the withers, the male has a small mane of the same yellowish color with the rest of the skin, and the tail has a tuft of black hair. It is never found a mile from water; islets in marshes and rivers are its favorite haunts, and it is quite unknown except in the central humid basin of Africa. Having a good deal of curiosity, it presents a noble appearance as it stands gazing, with head erect, at the approaching stranger. When it resolves to decamp, it lowers its head, and lays its horns down to a level with the withers; it then begins with a waddling trot, which ends in its galloping and springing over bushes like the pallahs. It invariably runs to the water, and crosses it by a succession of bounds, each of which appears to be from the bottom. We thought the flesh good at first, but soon got tired of it.
Great shoals of excellent fish come down annually with the access of waters. The mullet ('Mugil Africanus') is the most abundant.
