crocodiles the more demand for medicine, or perhaps because they preferred to eat the dog themselves. Many of the natives of this quarter are known, as in the South Seas, to eat the dog without paying any attention to its feeding. The dice doctor or diviner is an important member of the community, being consulted by Portuguese and natives alike. Part of his business is that of a detective, it being his duty to discover thieves. When goods are stolen, he goes and looks at the place, casts his dice, and waits a few days, and then, for a consideration, tells who is the thief: he is generally correct, for he trusts not to his dice alone; he has confidential agents all over the village, by whose inquiries and information he is enabled to detect the culprit. Since the introduction of muskets, gun doctors have sprung up, and they sell the medicine which professes to make good marksmen; others are rain doctors, etc., etc. The various schools deal in little charms, which are hung round the purchaser’s neck to avert evil: some of them contain the medicine, others increase its power.
Indigo, about three or four feet high, grows in great luxuriance in the streets of Tette, and so does the senna plant. The leaves are undistinguishable from those imported in England. A small amount of first-rate cotton is cultivated by the native population for the manufacture of a coarse cloth. A neighbouring tribe raises the sugar-cane, and makes a little sugar; but they use most primitive wooden rollers, and having no skill in mixing lime with the extracted juice, the product is of course of very inferior quality. Plenty of magnetic iron ore is found near Tette, and coal also to any amount; a single cliff-seam measuring twenty-five feet in thickness. It was found to burn well in the steamer on the first trial. Gold is washed for in the beds of rivers, within a couple of days of Tette. The natives are fully aware of its value, but seldom search for it, and never dig deeper than four or five feet. They dread lest the falling in of the sand of the river’s bed should bury them. In former times, when traders went with hundreds of slaves to the washings, the produce was considerable. It is now insignificant. The gold-producing lands have always been in the hands of independent tribes. Deep cuttings near the sources of the gold-yielding streams seem never to have been tried here, as in California and Australia, nor has any machinery been used save common wooden basins for washing.
CHAPTER II
Kebrabasa Rapids—Tette—African fever—Exploration of the Shiré—Discovery of Lake Shirwa.
Our curiosity had been so much excited by the reports we had heard of the Kebrabasa rapids, that we resolved to make a short examination of them, and seized the opportunity of the Zambesi being unusually low, to endeavour to ascertain their character while uncovered by the water. We reached them on the 9th of November. The country between Tette and Panda Mokua, where navigation ends, is well wooded and hilly on both banks. Panda Mokua is a hill two miles below the rapids, capped with dolomite containing copper ore.
Conspicuous among the trees, for its gigantic size, and bark coloured exactly like Egyptian syenite, is the burly Baobab. It often makes the other trees of the forest look like mere bushes in comparison. A hollow one, already mentioned, is 74 feet in circumference, another was 84, and some have been found on the West Coast which measure 100 feet. The lofty range of Kebrabasa, consisting chiefly of conical hills, covered with scraggy trees, crosses the Zambesi, and confines it within a narrow, rough, and rocky dell of about a quarter of a mile in breadth; over this, which may be called the flood-bed of the river, large masses of rock are huddled in indescribable confusion. The drawing, for the use of which, and of others, our thanks are due to Lord Russell, conveys but a faint idea of the scene, inasmuch as the hills which confine the river do not appear in the sketch. The chief rock is syenite, some portions of which have a beautiful blue tinge like lapis lazuli diffused through them; others are grey. Blocks of granite also abound, of a pinkish tinge; and these with metamorphic rocks, contorted, twisted, and thrown into every conceivable position, afford a picture of dislocation or unconformability which would gladden a geological lecturer’s heart; but at high flood this rough channel is all smoothed over, and it then conforms well with the river below it, which is half a mile wide. In the dry season the stream runs at the bottom of a narrow and deep groove, whose sides are polished and fluted by the boiling action of the water in flood, like the rims of ancient Eastern wells by the draw-ropes. The breadth of the groove is often not more than from forty to sixty yards, and it has some sharp turnings, double channels, and little cataracts in it. As we steamed up, the masts of the “Ma Robert,” though some thirty feet high, did not reach the level of the flood-channel above, and the man in the chains sung out, “No bottom at ten fathoms.” Huge pot-holes, as large as draw-wells, had been worn in the sides, and were so deep that in some instances, when protected from the sun by overhanging boulders, the water in them was quite cool. Some of these holes had been worn right through, and only the side next the rock remained; while the sides of the groove of the flood-channel were polished as smooth as if they had gone through the granite-mills of Aberdeen. The pressure of the water must be enormous to produce this polish. It had wedged round pebbles into chinks and crannies of the rocks so firmly that, though they looked quite loose, they could not be moved except with a hammer. The mighty power of the water here seen gave us an idea of what is going on in thousands of cataracts in the world. All the information we had been able to obtain from our Portuguese friends amounted to this, that some three or four detached rocks jutted out of the river in Kebrabasa, which, though dangerous to the cumbersome native canoes, could be easily passed by a steamer, and that if one or two of these obstructions were blasted away with gunpowder, no difficulty would hereafter be experienced. After we had painfully explored seven or eight miles of the rapid, we returned to the vessel satisfied that much greater labour was requisite for the mere examination of the cataracts than our friends supposed necessary to remove them; we therefore went down the river for fresh supplies, and made preparation for a more serious survey of this region.
The steamer having returned from the bar, we set out on the 22nd of November to examine the rapids of Kebrabasa. We reached the foot of the hills again, late in the afternoon of the 24th, and anchored in the stream. Canoe-men never sleep on the river, but always spend the night on shore. The natives on the right bank, in the country called Shidima, who are Banyai, and even at this short distance from Tette, independent, and accustomed to lord it over Portuguese traders, wondered what could be our object in remaining afloat, and were naturally suspicious at our departing from the universal custom.
They hailed us from the bank in the evening with “Why don’t you come and sleep onshore like other people?”
The answer they received from our Makololo, who now felt as independent as the Banyai, was, “We are held to the bottom with iron; you may see we are not like your Bazungu.”
This hint, a little amplified, saved us from the usual exactions. It is pleasant to give a present, but that pleasure the Banyai usually deny to strangers by making it a fine, and demanding it in such a supercilious way, that only a sorely cowed trader could bear it. They often refuse to touch what is offered—throw it down and leave it—sneer at the trader’s slaves, and refuse a passage until the tribute is raised to the utmost extent of his means.
Leaving the steamer next morning, we proceeded on foot, accompanied by a native Portuguese and his men and a dozen Makololo, who carried our baggage. The morning was pleasant, the hills on our right furnished for a time a delightful shade; but before long the path grew frightfully rough, and the hills no longer shielded us from the blazing sun. Scarcely a vestige of a track was now visible; and, indeed, had not our guide assured us to the contrary, we should have been innocent of even the suspicion of a way along the patches of soft yielding sand, and on the great rocks over which we so painfully clambered. These rocks have a singular appearance, from being dislocated and twisted in every direction, and covered with a thin black glaze, as if highly polished and coated with lamp-black varnish. This seems to have been deposited while the river was in flood, for it covers only those rocks which lie between the highest water-mark and a line about four feet above the lowest. Travellers who have visited the rapids of the Orinoco and the Congo say that the rocks there have a similar appearance, and it is attributed to some deposit from the water, formed only when the current is strong. This may account for it in part here, as it prevails only where the narrow river is confined between masses of rock, backed by high hills, and where the current in floods is known to be the strongest;
