Twelve days after our departure from the wagons at Ngabisane we came to the northeast end of Lake Ngami; and on the 1st of August, 1849, we went down together to the broad part, and, for the first time, this fine-looking sheet of water was beheld by Europeans. The direction of the lake seemed to be N.N.E. and S.S.W. by compass. The southern portion is said to bend round to the west, and to receive the Teoughe from the north at its northwest extremity. We could detect no horizon where we stood looking S.S.W., nor could we form any idea of the extent of the lake, except from the reports of the inhabitants of the district; and, as they professed to go round it in three days, allowing twenty-five miles a day would make it seventy-five, or less than seventy geographical miles in circumference. Other guesses have been made since as to its circumference, ranging between seventy and one hundred miles. It is shallow, for I subsequently saw a native punting his canoe over seven or eight miles of the northeast end; it can never, therefore, be of much value as a commercial highway. In fact, during the months preceding the annual supply of water from the north, the lake is so shallow that it is with difficulty cattle can approach the water through the boggy, reedy banks. These are low on all sides, but on the west there is a space devoid of trees, showing that the waters have retired thence at no very ancient date. This is another of the proofs of desiccation met with so abundantly throughout the whole country. A number of dead trees lie on this space, some of them imbedded in the mud, right in the water. We were informed by the Bayeiye, who live on the lake, that when the annual inundation begins, not only trees of great size, but antelopes, as the springbuck and tsessebe ('Acronotus lunata'), are swept down by its rushing waters; the trees are gradually driven by the winds to the opposite side, and become imbedded in mud.
The water of the lake is perfectly fresh when full, but brackish when low; and that coming down the Tamunak'le we found to be so clear, cold, and soft, the higher we ascended, that the idea of melting snow was suggested to our minds. We found this region, with regard to that from which we had come, to be clearly a hollow, the lowest point being Lake Kumadau; the point of the ebullition of water, as shown by one of Newman's barometric thermometers, was only between 207-1/2 Deg. and 206 Deg., giving an elevation of not much more than two thousand feet above the level of the sea. We had descended above two thousand feet in coming to it from Kolobeng. It is the southern and lowest part of the great river system beyond, in which large tracts of country are inundated annually by tropical rains, hereafter to be described. A little of that water, which in the countries farther north produces inundation, comes as far south as 20d 20', the latitude of the upper end of the lake, and instead of flooding the country, falls into the lake as into a reservoir. It begins to flow down the Embarrah, which divides into the rivers Tzo and Teoughe. The Tzo divides into the Tamunak'le and Mababe; the Tamunak'le discharges itself into the Zouga, and the Teoughe into the lake. The flow begins either in March or April, and the descending waters find the channels of all these rivers dried out, except in certain pools in their beds, which have long dry spaces between them. The lake itself is very low. The Zouga is but a prolongation of the Tamunak'le, and an arm of the lake reaches up to the point where the one ends and the other begins. The last is narrow and shallow, while the Zouga is broad and deep. The narrow arm of the lake, which on the map looks like a continuation of the Zouga, has never been observed to flow either way. It is as stagnant as the lake itself.
The Teoughe and Tamunak'le, being essentially the same river, and receiving their supplies from the same source (the Embarrah or Varra), can never outrun each other. If either could, or if the Teoughe could fill the lake—a thing which has never happened in modern times—then this little arm would prove a convenient escapement to prevent inundation. If the lake ever becomes lower than the bed of the Zouga, a little of the water of the Tamunak'le might flow into it instead of down the Zouga; we should then have the phenomenon of a river flowing two ways; but this has never been observed to take place here, and it is doubtful if it ever can occur in this locality. The Zouga is broad and deep when it leaves the Tamunak'le, but becomes gradually narrower as you descend about two hundred miles; there it flows into Kumadau, a small lake about three or four miles broad and twelve long. The water, which higher up begins to flow in April, does not make much progress in filling this lake till the end of June. In September the rivers cease to flow. When the supply has been more than usually abundant, a little water flows beyond Kumadau, in the bed first seen by us on the 4th of July; if the quantity were larger, it might go further in the dry rocky bed of the Zouga, since seen still further to the east. The water supply of this part of the river system, as will be more fully explained further on, takes place in channels prepared for a much more copious flow. It resembles a deserted Eastern garden, where all the embankments and canals for irrigation can be traced, but where, the main dam and sluices having been allowed to get out of repair, only a small portion can be laid under water. In the case of the Zouga the channel is perfect, but water enough to fill the whole channel never comes down; and before it finds its way much beyond Kumadau, the 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. They are caught in nets.
The 'Glanis siluris', a large, broad-headed fish, without scales, and barbed—called by the natives "mosala"—attains an enormous size and fatness. They are caught so large that when a man carries one over his shoulder the tail reaches the ground. It is a vegetable feeder, and in many of its habits resembles the eel. Like most lophoid fishes, it has the power of retaining a large quantity of water in a part of its great head, so that it can leave the river, and even be buried in the mud of dried-up pools, without being destroyed. Another fish closely resembling this, and named 'Clarias capensis' by Dr. Smith, is widely diffused throughout the interior, and often leaves the rivers for the sake of feeding in pools. As these dry up, large numbers of them are entrapped by the people. A water-snake, yellow-spotted and dark brown, is often seen swimming along with its head above the water: it is quite harmless, and is relished as food by the Bayeiye.
They mention ten kinds of fish in their river; and, in their songs of praise to the Zouga, say, "The messenger sent in haste is always forced to spend the night on the way by the abundance of food you place before him." The Bayeiye live much on fish, which is quite an abomination to the Bechuanas of the south; and they catch them in large numbers by means of nets made of the fine, strong fibres of the hibiscus, which grows abundantly in all moist places. Their float-ropes are made of the ife, or, as it is now called, the 'Sanseviere Angolensis', a flag-looking plant, having a very strong fibre, that abounds from Kolobeng to Angola; and the floats themselves are pieces of a water-plant containing valves at each joint, which retain the air in cells about an inch long. The mode of knotting the nets is identical with our own.
They also spear the fish with javelins having a light handle, which readily floats on the surface. They show great dexterity in harpooning the hippopotamus; and, the barbed blade of the spear being attached to a rope made of the young leaves of the palmyra, the animal can not rid himself of the canoe, attached to him in whale fashion, except by smashing it, which he not unfrequently does by his teeth or by a stroke of his hind foot.
On returning to the Bakurutse, we found that their canoes for fishing were simply large bundles of reeds tied together. Such a canoe would be a ready extemporaneous pontoon for crossing any river that had reedy banks.

Having returned to Kolobeng, I remained there till April, 1850, and then left in company with Mrs. Livingstone, our three children, and the chief Sechele—who had now bought a wagon of his own—in order to go across the Zouga at its lower end, with the intention of proceeding up the northern bank till we gained the Tamunak'le, and of then ascending that river to visit Sebituane in the north. Sekomi had given orders to fill up the wells which we had dug with so much labor at Serotli, so we took the more eastern route through the Bamangwato town and by Letloche. That chief asked why I had avoided him in our former journeys. I replied that my reason was that I knew he did not wish me to go to the lake, and I did not want to quarrel with him. "Well," he said, "you beat me then, and I am content."
Parting with Sechele at the ford, as he was eager to visit Lechulatebe, we went along the northern woody bank of the Zouga with great labor, having to cut down very many trees to allow the wagons to pass. Our losses by oxen falling into pitfalls were very heavy. The Bayeiye kindly opened the pits when they knew of our approach; but when that was not the case, we could blame no one on finding an established custom of the country inimical to our interests. On approaching the confluence of the Tamunak'le we were informed that the fly called tsetse* abounded on its banks. This was a barrier we never expected to meet; and, as it might have brought our wagons to a complete stand-still in a wilderness, where no supplies for the children could be obtained, we were reluctantly compelled to recross the Zouga.
* 'Glossina morsitans', the first specimens of which werebrought to England in 1848 by my friend Major Vardon, from thebanks of the Limpopo.
From the Bayeiye we learned that a party of Englishmen, who had come to the lake in search of ivory, were all laid low by fever, so we traveled hastily down about sixty miles to render what aid was in our power. We were grieved to find, as we came near, that Mr. Alfred Rider, an enterprising young artist who had come to make sketches of this country and of the lake immediately after its discovery, had died of fever before our arrival; but by the aid of medicines and such comforts as could be made by the only English lady who ever visited the lake, the others happily recovered. The unfinished drawing of Lake Ngami was made by Mr. Rider just before his death, and has been kindly lent for this work by his bereaved mother.
Sechele used all his powers of eloquence with Lechulatebe to induce him to furnish guides that I might be able to visit Sebituane on ox-back, while Mrs. Livingstone and the children remained at Lake Ngami. He yielded at last. I had a very superior London-made gun, the gift of Lieutenant Arkwright, on which I placed the greatest value, both on account of the donor and the impossibility of my replacing it. Lechulatebe fell violently in love with it, and offered whatever number of elephants' tusks I might ask for it. I too was enamored with Sebituane; and as he promised in addition that he would furnish Mrs. Livingstone with meat all the time of my absence, his arguments made me part with the gun. Though he had no ivory at the time to pay me, I felt the piece would be well spent on those terms, and delivered it to him. All being ready for our departure, I took Mrs. Livingstone about six miles from the town, that she might have a peep at the broad part of the lake. Next morning we had other work to do than part, for our little boy and girl were seized with fever. On the day following, all our servants were down too with the same complaint. As nothing is better in these cases than change of place, I was forced to give up the hope of seeing Sebituane that year; so, leaving my gun as part payment for guides next year, we started for the pure air of the Desert.
Some mistake had happened in the arrangement with Mr. Oswell, for we met him on the Zouga on our return, and he devoted the rest of this season to elephant-hunting, at which the natives universally declare he is the greatest adept that ever came into the country. He hunted without dogs. It is remarkable that this lordly animal is so completely harassed by the presence of a few yelping curs as to be quite incapable of attending to man. He makes awkward attempts to crush them by falling on his knees; and sometimes places his forehead against a tree ten inches in diameter; glancing on one side of the tree and then on the other, he pushes it down before him, as if he thought thereby to catch his enemies. The only danger the huntsman has to apprehend is the dogs running toward him, and thereby leading the elephant to their master. Mr. Oswell has been known to kill four large old male elephants a day. The value of the ivory in these cases would be one hundred guineas. We had reason to be proud of his success, for the inhabitants conceived from it a very high idea of English courage; and when they wished to flatter me would say, "If you were not a missionary you would just be like Oswell; you would not hunt with dogs either." When, in 1852, we came to the Cape, my black coat eleven years out of fashion, and without a penny of salary to draw, we found that Mr. Oswell had most generously ordered an outfit for the half-naked children, which cost about 200 Pounds, and presented it to us, saying he thought Mrs. Livingstone had a right to the game of her own preserves.
Foiled in this second attempt to reach Sebituane, we returned again to Kolobeng, whither we were soon followed by a number of messengers from that chief himself. When he heard of our attempts to visit him, he dispatched three detachments of his men with thirteen brown cows to Lechulatebe, thirteen white cows to Sekomi, and thirteen black cows to Sechele, with a request to each to assist the white men to reach him. Their policy, however, was to keep him out of view, and act as his agents in purchasing with his ivory the goods he wanted. This is thoroughly African; and that continent being without friths and arms of the sea, the tribes in the centre have always been debarred from European intercourse by its universal prevalence among all the people around the coasts.
Before setting out on our third journey to Sebituane, it was necessary to visit Kuruman; and Sechele, eager, for the sake of the commission thereon, to get the ivory of that chief into his own hands, allowed all the messengers to leave before our return. Sekomi, however, was more than usually gracious, and even furnished us with a guide, but no one knew the path beyond Nchokotsa which we intended to follow. When we reached that point, we found that the main spring of the gun of another of his men, who was well acquainted with the Bushmen, through whose country we should pass, had opportunely broken. I never undertook to mend a gun with greater zest than this; for, under promise of his guidance, we went to the north instead of westward. All the other guides were most liberally rewarded by Mr. Oswell.
We passed quickly over a hard country, which is perfectly flat. A little soil lying on calcareous tufa, over a tract of several hundreds of miles, supports a vegetation of fine sweet short grass, and mopane and baobab trees. On several parts of this we found large salt-pans, one of which, Ntwetwe, is fifteen miles broad and one hundred long. The latitude might have been taken on its horizon as well as upon the sea.
Although these curious spots seem perfectly level, all those in this direction have a gentle slope to the northeast: thither the rain-water, which sometimes covers them, gently gravitates. This, it may be recollected, is the direction of the Zouga. The salt dissolved in the water has by this means all been transferred to one pan in that direction, named Chuantsa; on it we see a cake of salt and lime an inch and a half thick. All the others have an efflorescence of lime and one of the nitrates only, and some are covered thickly with shells. These shells are identical with those of the mollusca of Lake Ngami and the Zouga. There are three varieties, spiral, univalve, and bivalve.
In every salt-pan in the country there is a spring of water on one side. I can remember no exception to this rule. The water of these springs is brackish, and contains the nitrate of soda. In one instance there are two springs, and one more saltish than the other. If this supply came from beds of rock salt the water would not be drinkable, as it generally is, and in some instances, where the salt contained in the pan in which these springs appear has been removed by human agency, no fresh deposit occurs. It is therefore probable that these deposits of salt are the remains of the very slightly brackish lakes of antiquity, large portions of which must have been dried out in the general desiccation. We see an instance in Lake Ngami, which, when low, becomes brackish, and this view seems supported by the fact that the largest quantities of salt have been found in the deepest hollows or lowest valleys, which have no outlet or outgoing gorge; and a fountain, about thirty miles south of the Bamangwato—the temperature of which is upward of 100 Deg.—while strongly impregnated with pure salt, being on a flat part of the country, is accompanied by no deposit.
When these deposits occur in a flat tufaceous country like the present, a large space is devoid of vegetation, on account of the nitrates dissolving the tufa, and keeping it in a state unfavorable to the growth of plants.
We found a great number of wells in this tufa. A place called Matlomagan-yana, or the "Links", is quite a chain of these never-failing springs. As they occasionally become full in seasons when no rain falls, and resemble somewhat in this respect the rivers we have already mentioned, it is probable they receive some water by percolation from the river system in the country beyond. Among these links we found many families of Bushmen; and, unlike those on the plains of the Kalahari, who are generally of short stature and light yellow color, these were tall, strapping fellows, of dark complexion. Heat alone does not produce blackness of skin, but heat with moisture seems to insure the deepest hue.
One of these Bushmen, named Shobo, consented to be our guide over the waste between these springs and the country of Sebituane. Shobo gave us no hope of water in less than a month. Providentially, however, we came sooner than we expected to some supplies of rain-water in a chain of pools. It is impossible to convey an idea of the dreary scene on which we entered after leaving this spot: the only vegetation was a low scrub in deep sand; not a bird or insect enlivened the landscape. It was, without exception, the most uninviting prospect I ever beheld; and, to make matters worse, our guide Shobo wandered on the second day. We coaxed him on at night, but he went to all points of the compass on the trails of elephants which had been here in the rainy season, and then would sit down in the path, and in his broken Sichuana say, "No water, all country only; Shobo sleeps; he breaks down; country only;" and then coolly curl himself up and go to sleep. The oxen were terribly fatigued and thirsty; and on the morning of the fourth day, Shobo, after professing ignorance of every thing, vanished altogether. We went on in the direction in which we last saw him, and about eleven o'clock began to see birds; then the trail of a rhinoceros. At this we unyoked the oxen, and they, apparently knowing the sign, rushed along to find the water in the River Mahabe, which comes from the Tamunak'le, and lay to the west of us. The supply of water in the wagons had been wasted by one of our servants, and by the afternoon only a small portion remained for the children. This was a bitterly anxious night; and next morning the less there was of water, the more thirsty the little rogues became. The idea of their perishing before our eyes was terrible. It would almost have been a relief to me to have been reproached with being the entire cause of the catastrophe; but not one syllable of upbraiding was uttered by their mother, though the tearful eye told the agony within. In the afternoon of the fifth day, to our inexpressible relief, some of the men returned with a supply of that fluid of which we had never before felt the true value.
The cattle, in rushing along to the water in the Mahabe, probably crossed a small patch of trees containing tsetse, an insect which was shortly to become a perfect pest to us. Shobo had found his way to the Bayeiye, and appeared, when we came up to the river, at the head of a party; and, as he wished to show his importance before his friends, he walked up boldly and commanded our whole cavalcade to stop, and to bring forth fire and tobacco, while he coolly sat down and smoked his pipe. It was such an inimitably natural way of showing off, that we all stopped to admire the acting, and, though he had left us previously in the lurch, we all liked Shobo, a fine specimen of that wonderful people, the Bushmen.
Next day we came to a village of Banajoa, a tribe which extends far to the eastward. They were living on the borders of a marsh in which the Mahabe terminates. They had lost their crop of corn ('Holcus sorghum'), and now subsisted almost entirely on the root called "tsitla", a kind of aroidoea, which contains a very large quantity of sweet-tasted starch. When dried, pounded into meal, and allowed to ferment, it forms a not unpleasant article of food. The women shave all the hair off their heads, and seem darker than the Bechuanas. Their huts were built on poles, and a fire is made beneath by night, in order that the smoke may drive away the mosquitoes, which abound on the Mababe and Tamunak'le more than in any other part of the country. The head man of this village, Majane, seemed a little wanting in ability, but had had wit enough to promote a younger member of the family to the office. This person, the most like the ugly negro of the tobacconists' shops I ever saw, was called Moroa Majane, or son of Majane, and proved an active guide across the River Sonta, and to the banks of the Chobe, in the country of Sebituane. We had come through another tsetse district by night, and at once passed our cattle over to the northern bank to preserve them from its ravages.
A few remarks on the Tsetse, or 'Glossina morsitans', may here be appropriate. It is not much larger than the common house-fly, and is nearly of the same brown color as the common honey-bee; the after part of the body has three or four yellow bars across it; the wings project beyond this part considerably, and it is remarkably alert, avoiding most dexterously all attempts to capture it with the hand at common temperatures; in the cool of the mornings and evenings it is less agile. Its peculiar buzz when once heard can never be forgotten by the traveler whose means of locomotion are domestic animals; for it is well known that the bite of this poisonous insect is certain death to the ox, horse, and dog. In this journey, though we were not aware of any great number having at any time lighted on our cattle, we lost forty-three fine oxen by its bite. We watched the animals carefully, and believe that not a score of flies were ever upon them.
A most remarkable feature in the bite of the tsetse is its perfect harmlessness in man and wild animals, and even calves, so long as they continue to suck the cows. We never experienced the slightest injury from them ourselves, personally, although we lived two months in their HABITAT, which was in this case as sharply defined as in many others, for the south bank of the Chobe was infested by them, and the northern bank, where our cattle were placed, only fifty yards distant, contained not a single specimen. This was the more remarkable, as we often saw natives carrying over raw meat to the opposite bank with many tsetse settled upon it.
The poison does not seem to be injected by a sting, or by ova placed beneath the skin; for, when one is allowed to feed freely on the hand, it is seen to insert the middle prong of three portions, into which the proboscis divides, somewhat deeply into the true skin; it then draws it out a little way, and it assumes a crimson color as the mandibles come into brisk operation. The previously shrunken belly swells out, and, if left undisturbed, the fly quietly departs when it is full. A slight itching irritation follows, but not more than in the bite of a mosquito. In the ox this same bite produces no more immediate effects than in man. It does not startle him as the gad-fly does; but a few days afterward the following symptoms supervene: the eye and nose begin to run, the coat stares as if the animal were cold, a swelling appears under the jaw, and sometimes at the navel; and, though the animal continues to graze, emaciation commences, accompanied with a peculiar flaccidity of the muscles, and this proceeds unchecked until, perhaps months afterward, purging comes on, and the animal, no longer able to graze, perishes in a state of extreme exhaustion. Those which are in good condition often perish soon after the bite is inflicted with staggering and blindness, as if the brain were affected by it. Sudden changes of temperature produced by falls of rain seem to hasten the progress of the complaint; but, in general, the emaciation goes on uninterruptedly for months, and, do what we will, the poor animals perish miserably.
When opened, the cellular tissue on the surface of the body beneath the skin is seen to be injected with air, as if a quantity of soap-bubbles were scattered over it, or a dishonest, awkward butcher had been trying to make it look fat. The fat is of a greenish-yellow color and of an oily consistence. All the muscles are flabby, and the heart often so soft that the fingers may be made to meet through it. The lungs and liver partake of the disease. The stomach and bowels are pale and empty, and the gall-bladder is distended with bile.
These symptoms seem to indicate what is probably the case, a poison in the blood, the germ of which enters when the proboscis is inserted to draw blood. The poison-germ, contained in a bulb at the root of the proboscis, seems capable, although very minute in quantity, of reproducing itself, for the blood after death by tsetse is very small in quantity, and scarcely stains the hands in dissection. I shall have by-and-by to mention another insect, which by the same operation produces in the human subject both vomiting and purging.
The mule, ass, and goat enjoy the same immunity from the tsetse as man and the game. Many large tribes on the Zambesi can keep no domestic animals except the goat, in consequence of the scourge existing in their country. Our children were frequently bitten, yet suffered no harm; and we saw around us numbers of zebras, buffaloes, pigs, pallahs and other antelopes, feeding quietly in the very habitat of the tsetse, yet as undisturbed by its bite as oxen are when they first receive the fatal poison. There is not so much difference in the natures of the horse and zebra, the buffalo and ox, the sheep and antelope, as to afford any satisfactory explanation of the phenomenon. Is a man not as much a domestic animal as a dog? The curious feature in the case, that dogs perish though fed on milk, whereas the calves escape so long as they continue sucking, made us imagine that the mischief might be produced by some plant in the locality, and not by tsetse; but Major Vardon, of the Madras Army, settled that point by riding a horse up to a small hill infested by the insect without allowing him time to graze, and, though he only remained long enough to take a view of the country and catch some specimens of tsetse on the animal, in ten days afterward the horse was dead.
The well-known disgust which the tsetse shows to animal excreta, as exhibited when a village is placed in its habitat, has been observed and turned to account by some of the doctors. They mix droppings of animals, human milk, and some medicines together, and smear the animals that are about to pass through a tsetse district; but this, though it proves a preventive at the time, is not permanent. There is no cure yet known for the disease. A careless herdsman allowing a large number of cattle to wander into a tsetse district loses all except the calves; and Sebituane once lost nearly the entire cattle of his tribe, very many thousands, by unwittingly coming under its influence. Inoculation does not insure immunity, as animals which have been slightly bitten in one year may perish by a greater number of bites in the next; but it is probable that with the increase of guns the game will perish, as has happened in the south, and the tsetse, deprived of food, may become extinct simultaneously with the larger animals.
The Makololo whom we met on the Chobe were delighted to see us; and as their chief Sebituane was about twenty miles down the river, Mr. Oswell and I proceeded in canoes to his temporary residence. He had come from the Barotse town of Naliele down to Sesheke as soon as he heard of white men being in search of him, and now came one hundred miles more to bid us welcome into his country. He was upon an island, with all his principal men around him, and engaged in singing when we arrived. It was more like church music than the sing-song ee ee ee, ae ae ae, of the Bechuanas of the south, and they continued the tune for some seconds after we approached. We informed him of the difficulties we had encountered, and how glad we were that they were all at an end by at last reaching his presence. He signified his own joy, and added, "Your cattle are all bitten by the tsetse, and will certainly die; but never mind, I have oxen, and will give you as many as you need." We, in our ignorance, then thought that as so few tsetse had bitten them no great mischief would follow. He then presented us with an ox and a jar of honey as food, and handed us over to the care of Mahale, who had headed the party to Kolobeng, and would now fain appropriate to himself the whole credit of our coming. Prepared skins of oxen, as soft as cloth, were given to cover us through the night; and, as nothing could be returned to this chief, Mahale became the owner of them. Long before it was day Sebituane came, and sitting down by the fire, which was lighted for our benefit behind the hedge where we lay, he narrated the difficulties he had himself experienced, when a young man, in crossing that same desert which we had mastered long afterward. As he has been most remarkable in his career, and was unquestionably the greatest man in all that country, a short sketch of his life may prove interesting to the reader.
Sebituane was about forty-five years of age; of a tall and wiry form, an olive or coffee-and-milk color, and slightly bald; in manner cool and collected, and more frank in his answers than any other chief I ever met. He was the greatest warrior ever heard of beyond the colony; for, unlike Mosilikatse, Dingaan, and others, he always led his men into battle himself. When he saw the enemy, he felt the edge of his battle-axe, and said, "Aha! it is sharp, and whoever turns his back on the enemy will feel its edge." So fleet of foot was he, that all his people knew there was no escape for the coward, as any such would be cut down without mercy. In some instances of skulking he allowed the individual to return home; then calling him, he would say, "Ah! you prefer dying at home to dying in the field, do you? You shall have your desire." This was the signal for his immediate execution.
He came from the country near the sources of the Likwa and Namagari rivers in the south, so we met him eight hundred or nine hundred miles from his birth-place. He was not the son of a chief, though related closely to the reigning family of the Basutu; and when, in an attack by Sikonyele, the tribe was driven out of one part, Sebituane was one in that immense horde of savages driven back by the Griquas from Kuruman in 1824.* He then fled to the north with an insignificant party of men and cattle. At Melita the Bangwaketse collected the Bakwains, Bakatla, and Bahurutse, to "eat them up". Placing his men in front, and the women behind the cattle, he routed the whole of his enemies at one blow. Having thus conquered Makabe, the chief of the Bangwaketse, he took immediate possession of his town and all his goods.
* See an account of this affair in Moffat's "MissionaryEnterprise in Africa".
Sebituane subsequently settled at the place called Litubaruba, where Sechele now dwells, and his people suffered severely in one of those unrecorded attacks by white men, in which murder is committed and materials laid up in the conscience for a future judgment.
A great variety of fortune followed him in the northern part of the Bechuana country; twice he lost all his cattle by the attacks of the Matabele, but always kept his people together, and retook more than he lost. He then crossed the Desert by nearly the same path that we did. He had captured a guide, and, as it was necessary to travel by night in order to reach water, the guide took advantage of this and gave him the slip. After marching till morning, and going as they thought right, they found themselves on the trail of the day before. Many of his cattle burst away from him in the phrensy of thirst, and rushed back to Serotli, then a large piece of water, and to Mashue and Lopepe, the habitations of their original owners. He stocked himself again among the Batletli, on Lake Kumadau, whose herds were of the large-horned species of cattle.* Conquering all around the lake, he heard of white men living at the west coast; and, haunted by what seems to have been the dream of his whole life, a desire to have intercourse with the white man, he passed away to the southwest, into the parts opened up lately by Messrs. Galton and Andersson. There, suffering intensely from thirst, he and his party came to a small well. He decided that the men, not the cattle, should drink it, the former being of most value, as they could fight for more should these be lost. In the morning they found the cattle had escaped to the Damaras.
