Still keeping the position facing the cataract, on its right side rises Mount Morumbwa from 2000 to 3000 feet high, which gives the name to the spot. On the left of the cataract stands a noticeable mountain which may be called onion-shaped, for it is partly conical and a large concave flake has peeled off, as granite often does, and left a broad, smooth convex face as if it were an enormous bulb. These two mountains extend their bases northwards about half a mile, and the river in that distance, still very narrow, is smooth, with a few detached rocks standing out from its bed. They climbed as high up the base of Mount Morumbwa, which touches the cataract, as they required. The rocks were all water-worn and smooth, with huge potholes, even at 100 feet above low water. When at a later period they climbed up the north-western base of this same mountain, the familiar face of the onion-shaped one opposite was at once recognised; one point of view on the talus of Mount Morumbwa was not more than 700 or 800 yards distant from the other, and they then completed the survey of Kebrabasa from end to end.
They did not attempt to return by the way they came, but scaled the slope of the mountain on the north. It took them three hours’ hard labour in cutting their way up through the dense thornbush which covered the ascent. The face of the slope was often about an angle of 70 degrees, yet their guide Shokumbenla, whose hard, horny soles, resembling those of elephants, showed that he was accustomed to this rough and hot work, carried a pot of water for them nearly all the way up. They slept that night at a well in a tufaceous rock on the N.W. of Chipereziwa, and never was sleep more sweet.
A band of native musicians came to our camp one evening, on our own way down, and treated us with their wild and not unpleasant music on the Marimba, an instrument formed of bars of hard wood of varying breadth and thickness, laid on different-sized hollow calabashes, and tuned to give the notes; a few pieces of cloth pleased them, and they passed on.
The rainy season of Tette differs a little from that of some of the other intertropical regions; the quantity of rain-fall being considerably less. It begins in November and ends in April. During our first season in that place, only a little over nineteen inches of rain fell. In an average year, and when the crops are good, the fall amounts to about thirty-five inches. On many days it does not rain at all, and rarely is it wet all day; some days have merely a passing shower, preceded and followed by hot sunshine; occasionally an interval of a week, or even a fortnight, passes without a drop of rain, and then the crops suffer from the sun. These partial droughts happen in December and January. The heat appears to increase to a certain point in the different latitudes so as to necessitate a change, by some law similar to that which regulates the intense cold in other countries. After several days of progressive heat here, on the hottest of which the thermometer probably reaches 103 degrees in the shade, a break occurs in the weather, and a thunderstorm cools the air for a time. At Kuruman, when the thermometer stood above 84 degrees, rain might be expected; at Kolobeng, the point at which we looked for a storm was 96 degrees. The Zambesi is in flood twice in the course of the year; the first flood, a partial one, attains its greatest height about the end of December or beginning of January; the second, and greatest, occurs after the river inundates the interior, in a manner similar to the overflow of the Nile, this rise not taking place at Tette until March. The Portuguese say that the greatest height which the March floods attain is thirty feet at Tette, and this happens only about every fourth year; their observations, however, have never been very accurate on anything but ivory, and they have in this case trusted to memory alone. The only fluviometer at Tette, or anywhere else on the river, was set up at our suggestion; and the first flood was at its greatest height of thirteen feet six inches on the 17th January, 1859, and then gradually fell a few feet, until succeeded by the greater flood of March. The river rises suddenly, the water is highly discoloured and impure, and there is a four-knot current in many places; but in a day or two after the first rush of waters is passed, the current becomes more equally spread over the whole bed of the river, and resumes its usual rate in the channel, although continuing in flood. The Zambesi water at other times is almost chemically pure, and the photographer would find that it is nearly as good as distilled water for the nitrate of silver bath.
A third visit to Kebrabasa was made for the purpose of ascertaining whether it might be navigable when the Zambesi was in flood, the chief point of interest being of course Morumbwa; it was found that the rapids observed in our first trip had disappeared, and that while they were smoothed over, in a few places the current had increased in strength. As the river fell rapidly while we were on the journey, the cataract of Morumbwa did not differ materially from what it was when discovered. Some fishermen assured us that it was not visible when the river was at its fullest, and that the current was then not very strong. On this occasion we travelled on the right bank, and found it, with the additional inconvenience of rain, as rough and fatiguing as the left had been. Our progress was impeded by the tall wet grass and dripping boughs, and consequent fever. During the earlier part of the journey we came upon a few deserted hamlets only; but at last in a pleasant valley we met some of the people of the country, who were miserably poor and hungry. The women were gathering wild fruits in the woods. A young man having consented for two yards of cotton cloth to show us a short path to the cataract led us up a steep hill to a village perched on the edge of one of its precipices; a thunderstorm coming on at the time, the headman invited us to take shelter in a hut until it had passed. Our guide having informed him of what he knew and conceived to be our object, was favoured in return with a long reply in well-sounding blank verse; at the end of every line the guide, who listened with deep attention, responded with a grunt, which soon became so ludicrous that our men burst into a loud laugh. Neither the poet nor the responsive guide took the slightest notice of their rudeness, but kept on as energetically as ever to the end. The speech, or more probably our bad manners, made some impression on our guide, for he declined, although offered double pay, to go any further.
A great deal of fever comes in with March and April; in March, if considerable intervals take place between the rainy days, and in April always, for then large surfaces of mud and decaying vegetation are exposed to the hot sun. In general an attack does not continue long, but it pulls one down quickly; though when the fever is checked the strength is as quickly restored. It had long been observed that those who were stationed for any length of time in one spot, and lived sedentary lives, suffered more from fever than others who moved about and had both mind and body occupied; but we could not all go in the small vessel when she made her trips, during which the change of place and scenery proved so conducive to health; and some of us were obliged to remain in charge of the expedition’s property, making occasional branch trips to examine objects of interest in the vicinity. Whatever may be the cause of the fever, we observed that all were often affected at the same time, as if from malaria. This was particularly the case during a north wind: it was at first commonly believed that a daily dose of quinine would prevent the attack. For a number of months all our men, except two, took quinine regularly every morning. The fever some times attacked the believers in quinine, while the unbelievers in its prophylactic powers escaped. Whether we took it daily, or omitted it altogether for months, made no difference; the fever was impartial, and seized us on the days of quinine as regularly and as severely as when it remained undisturbed in the medicine chest, and we finally abandoned the use of it as a prophylactic altogether. The best preventive against fever is plenty of interesting work to do, and abundance of wholesome food to eat. To a man well housed and clothed, who enjoys these advantages, the fever at Tette will not prove a more formidable enemy than a common cold; but let one of these be wanting—let him be indolent, or guilty of excesses in eating or drinking, or have poor, scanty fare,—and the fever will probably become a more serious matter. It is of a milder type at Tette than at Quillimane or on the low sea-coast; and, as in this part of Africa one is as liable to fever as to colds in England, it would be advisable for strangers always to hasten from the coast to the high lands, in order that when the seizure does take place, it may be of the mildest type. Although quinine was not found to be a preventive, except possibly in the way of acting as a tonic, and rendering the system more able to resist the influence of malaria, it was found invaluable in the cure of the complaint, as soon as pains in the back, sore bones, headache, yawning, quick and sometimes intermittent pulse, noticeable pulsations of the jugulars, with suffused eyes, hot skin, and foul tongue, began. 1
Very curious are the effects of African fever on certain minds. Cheerfulness vanishes, and the whole mental horizon is overcast with black clouds of gloom and sadness. The liveliest joke cannot provoke even the semblance of a smile. The countenance is grave, the eyes suffused, and the few utterances are made in the piping voice of a wailing infant. An irritable temper is often the first symptom of approaching fever. At such times a man feels very much like a fool, if he does not act like one. Nothing is right, nothing pleases the fever-stricken victim. He is peevish, prone to find fault and to contradict, and think himself insulted, and is exactly what an Irish naval surgeon before a court-martial defined a drunken man to be: “a man unfit for society.”
Finding that it was impossible to take our steamer of only ten-horse power through Kebrabasa, and convinced that, in order to force a passage when the river was in flood, much greater power was required, due information was forwarded to Her Majesty’s Government, and application made for a more suitable vessel. Our attention was in the mean time turned to the exploration of the river Shiré, a northern tributary of the Zambesi, which joins it about a hundred miles from the sea. We could learn nothing satisfactory from the Portuguese regarding this affluent; no one, they said, had ever been up it, nor could they tell whence it came. Years ago a Portuguese expedition is said, however, to have attempted the ascent, but to have abandoned it on account of the impenetrable duckweed (Pistia stratiotes.) We could not learn from any record that the Shiré had ever been ascended by Europeans. As far, therefore, as we were concerned, the exploration was absolutely new. All the Portuguese believed the Manganja to be brave but bloodthirsty savages; and on our return we found that soon after our departure a report was widely spread that our temerity had been followed by fatal results, Dr. Livingstone having been shot, and Dr. Kirk mortally wounded by poisoned arrows.
Our first trip to the Shiré was in January, 1859. A considerable quantity of weed floated down the river for the first twenty-five miles, but not sufficient to interrupt navigation with canoes or with any other craft. Nearly the whole of this aquatic plant proceeds from a marsh on the west, and comes into the river a little beyond a lofty hill called Mount Morambala. Above that there is hardly any. As we approached the villages, the natives collected in large numbers, armed with bows and poisoned arrows; and some, dodging behind trees, were observed taking aim as if on the point of shooting. All the women had been sent out of the way, and the men were evidently prepared to resist aggression. At the village of a chief named Tingané, at least five hundred natives collected and ordered us to stop. Dr. Livingstone went ashore; and on his explaining that we were English and had come neither to take slaves nor to fight, but only to open a path by which our countrymen might follow to purchase cotton, or whatever else they might have to sell, except slaves, Tingané became at once quite friendly. The presence of the steamer, which showed that they had an entirely new people to deal with, probably contributed to this result; for Tingané was notorious for being the barrier to all intercourse between the Portuguese black traders and the natives further inland; none were allowed to pass him either way. He was an elderly, well-made man, grey-headed, and over six feet high. Though somewhat excited by our presence, he readily complied with the request to call his people together, in order that all might know what our objects were.
In commencing intercourse with any people we almost always referred to the English detestation of slavery. Most of them already possess some information respecting the efforts made by the English at sea to suppress the slave-trade; and our work being to induce them to raise and sell cotton, instead of capturing and selling their fellow-men, our errand appears quite natural; and as they all have clear ideas of their own self-interest, and are keen traders, the reasonableness of the proposal is at once admitted; and as a belief in a Supreme Being, the Maker and Ruler of all things, and in the continued existence of departed spirits, is universal, it becomes quite appropriate to explain that we possess a Book containing a Revelation of the will of Him to whom in their natural state they recognise no relationship. The fact that His Son appeared among men, and left His words in His Book, always awakens attention; but the great difficulty is to make them feel that they have any relationship to Him, and that He feels any interest in them. The numbness of moral perception exhibited, is often discouraging; but the mode of communication, either by interpreters, or by the imperfect knowledge of the language, which not even missionaries of talent can overcome save by the labour of many years, may, in part, account for the phenomenon. However, the idea of the Father of all being displeased with His children, for selling or killing each other, at once gains their ready assent: it harmonizes so exactly with their own ideas of right and wrong. But, as in our own case at home, nothing less than the instruction and example of many years will secure their moral elevation.
The dialect spoken here closely resembles that used at Senna and Tette. We understood it at first only enough to know whether our interpreter was saying what we bade him, or was indulging in his own version. After stating pretty nearly what he was told, he had an inveterate tendency to wind up with “The Book says you are to grow cotton, and the English are to come and buy it,” or with some joke of his own, which might have been ludicrous, had it not been seriously distressing.
In the first ascent of the Shiré our attention was chiefly directed to the river itself. The delight of threading out the meanderings of upwards of 200 miles of a hitherto unexplored river must be felt to be appreciated. All the lower part of the river was found to be at least two fathoms in depth. It became shallower higher up, where many departing and re-entering branches diminished the volume of water, but the absence of sandbanks made it easy of navigation. We had to exercise the greatest care lest anything we did should be misconstrued by the crowds who watched us. After having made, in a straight line, one hundred miles, although the windings of the river had fully doubled the distance, we found further progress with the steamer arrested, in 15 degrees 55 minutes south, by magnificent cataracts, which we called, “The Murchison,” after one whose name has already a world-wide fame, and whose generous kindness we can never repay. The native name of that figured in the woodcut is Mamvira. It is that at which the progress of the steamer was first stopped. The angle of descent is much smaller than that of the five cataracts above it; indeed, so small as compared with them, that after they were discovered this was not included in the number.
A few days were spent here in the hope that there might be an opportunity of taking observations for longitude, but it rained most of the time, or the sky was overcast. It was deemed imprudent to risk a land journey whilst the natives were so very suspicious as to have a strong guard on the banks of the river night and day; the weather also was unfavourable. After sending presents and messages to two of the chiefs, we returned to Tette. In going down stream our progress was rapid, as we were aided by the current. The hippopotami never made a mistake, but got out of our way. The crocodiles, not so wise, sometimes rushed with great velocity at us, thinking that we were some huge animal swimming. They kept about a foot from the surface, but made three well-defined ripples from the feet and body, which marked their rapid progress; raising the head out of the water when only a few yards from the expected feast, down they went to the bottom like a stone, without touching the boat.
