As the water was now low, they proceeded in the canoe to an island in the centre of the river, the further end of which extended to the edge of the falls. At the spot where they landed it was impossible to discover where the vast body of water disappeared. It seemed, indeed, suddenly to sink into the earth, for the opposite lip of the fissure into which it descends was only eighty feet distant. On peering over the precipice the doctor saw the stream, a thousand yards broad, leaping down a hundred feet and then becoming suddenly compressed into a space of fifteen or twenty yards, when, instead of flowing as before, it turned directly to the right, and went boiling and rushing amid the hills. The vapour which rushes up from this cauldron to the height of two or three hundred feet, being condensed, changes its hue to that of dark smoke, and then comes down in a constant shower. The chief portion falls on the opposite side of the fissure, where grow a number of evergreen trees, their leaves always wet. The walls of this gigantic crack are perpendicular. Altogether, Dr Livingstone considered these falls the most wonderful sight he had beheld in Africa. Returning to Kalai the doctor and his party met Sekeletu, and, bidding him a final farewell, set off northwards to Lekone, through a beautiful country, on the 20th of November. The further they advanced the more the country swarmed with inhabitants, and great numbers came to see the white man, invariably bringing presents of maize. The natives of this region have a curious way of saluting a stranger. Instead of bowing they throw themselves on their backs on the ground, rolling from side to side and slapping the outsides of their thighs, while they utter the words "_Kina bomba! kina bomba_!" In vain the doctor implored them to stop. They, imagining him pleased, only tumbled about more fiercely and slapped their thighs with greater vehemence. These villagers supplied the party abundantly with ground nuts, maize, and corn. When the doctor addressed them and told them of Jesus as their Saviour-- how He had come on earth to bring peace and goodwill to men--they replied: "We are tired of flight. Give us rest and sleep,"--though, of course, they could not understand the full import of the message. These people appeared humbled by the scourgings they had received from their enemies, and seemed to be in a favourable state for the reception of the Gospel. Their chief, Monze, came one Sunday morning, wrapped in a large cloth, when, like his followers, he rolled himself about in the dust, screaming out "_Kina bomba_!" He had never before seen a white man, but had met with black native traders, who came, he said, for ivory, but not for slaves. His wife would have been good-looking, had she not followed the custom of her country by knocking out her teeth. Monze soon made himself at home, and presented the travellers with as much food as they required.
