When we reached the foot of the mountain named Chipereziwa, whose perpendicular rocky sides are clothed with many-coloured lichens, our Portuguese companion informed us there were no more obstructions to navigation, the river being all smooth above; he had hunted there and knew it well.Supposing that the object of our trip was accomplished we turned back; but two natives, who came to our camp at night, assured us that a cataract, called Morumbwa, did still exist in front.Drs.Livingstone and Kirk then decided to go forward with three Makololo and settle the question for themselves.It was as tough a bit of travel as they ever had in Africa, and after some painful marching the Badema guides refused to go further; "the Banyai," they said, "would be angry if they showed white men the country; and there was besides no practicable approach to the spot, neither elephant, nor hippopotamus, nor even a crocodile could reach the cataract."The slopes of the mountains on each side of the river, now not 300 yards wide, and without the flattish flood-channel and groove, were more than 3000 feet from the sky-line down, and were covered either with dense thornbush or huge black boulders; this deep trough-like shape caused the sun's rays to converge as into a focus, making the surface so hot that the soles of the feet of the Makololo became blistered.Around, and up and down, the party clambered among these heated blocks, at a pace not exceeding a mile an hour; the strain upon the muscles in jumping from crag to boulder, and wriggling round projections, took an enormous deal out of them, and they were often glad to cower in the shadow formed by one rock overhanging and resting on another; the shelter induced the peculiarly strong and overpowering inclination to sleep, which too much sun sometimes causes.This sleep is curative of what may be incipient sunstroke:in its first gentle touches, it caused the dream to flit over the boiling brain, that they had become lunatics and had been sworn in as members of the Alpine club; and then it became so heavy that it made them feel as if a portion of existence had been cut out from their lives.The sun is excessively hot, and feels sharp in Africa; but, probably from the greater dryness of the atmosphere, we never heard of a single case of sunstroke, so common in India.The Makololo told Dr. Livingstone they "always thought he had a heart, but now they believed he had none," and tried to persuade Dr. Kirk to return, on the ground that it must be evident that, in attempting to go where no living foot could tread, his leader had given unmistakeable signs of having gone mad.All their efforts of persuasion, however, were lost upon Dr. Kirk, as he had not yet learned their language, and his leader, knowing his companion to be equally anxious with himself to solve the problem of the navigableness of Kebrabasa, was not at pains to enlighten him.At one part a bare mountain spur barred the way, and had to be surmounted by a perilous and circuitous route, along which the crags were so hot that it was scarcely possible for the hand to hold on long enough to ensure safety in the passage; and had the foremost of the party lost his hold, he would have hurled all behind him into the river at the foot of the promontory; yet in this wild hot region, as they descended again to the river, they met a fisherman casting his hand-net into the boiling eddies, and he pointed out the cataract of Morumbwa; within an hour they were trying to measure it from an overhanging rock, at a height of about one hundred feet.When you stand facing the cataract, on the north bank, you see that it is situated in a sudden bend of the river, which is flowing in a short curve; the river above it is jammed between two mountains in a channel with perpendicular sides, and less than fifty yards wide; one or two masses of rock jut out, and then there is a sloping fall of perhaps twenty feet in a distance of thirty yards.It would stop all navigation, except during the highest floods; the rocks showed that the water then rises upwards of eighty feet perpendicularly.
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.
