The expedition having heard of the Kebrabasa Falls, steamed up the river, and on the 24th of November reached Panda Mokua, where the navigation ends, about two miles below them. Hence the party started overland, by a frightfully rough path among rocky hills, where no shade was to be found. At last their guides declared that they could go no further; indeed, the surface of the ground was so hot that the soles of the Makololos’ feet became blistered. The travellers, however, pushed on. Passing round a steep promontory, they beheld the river at their feet, the channel jammed in between two mountains with perpendicular sides, and less than fifty yards wide. There is a sloping fall of about twenty feet in height, and another at a distance of thirty yards above it. When, however, the river rises upwards of eighty feet perpendicularly, as it does in the rainy season, the cataract might be passed in boats.
After returning to Tete, the steamer went up the Shire, January, 1859. The natives, as they passed them, collected at their villages in large numbers, armed with bows and poisoned arrows, threatening to attack them. Dr Livingstone, however, went on shore, and explained to the chief, Tingane, that they had come neither to take slaves nor to fight, but wished to open up a path by which his countrymen could ascend to purchase their cotton. On this Tingane at once became friendly.
Their progress was arrested, after steaming up a hundred miles in a straight line, although, counting the windings of the river, double that distance, by magnificent cataracts known to the natives as those of the Mamvira, but called by the expedition the Murchison Falls.
Rain prevented them making observations, and they returned at a rapid rate down the river.
A second trip up it was made in March of the same year. They here gained the friendship of Chibisa, a shrewd and intelligent chief, whose village was about ten miles below the cataracts. He told the doctor that a few years before his little daughter had been kidnapped, and was now a slave to the padre at Tete, asking him, if possible, to ransom the child.
From hence Dr Livingstone and Dr Kirk proceeded on foot in a northerly direction to Lake Shirwa. The natives turned out from their villages, sounding notes of defiance on their drums; but the efforts to persuade them that their visitors came as friends were successful, and the lake was discovered on the 18th of April.
From having no outlet, the water is brackish, with hilly islands rising out of it. The country around appeared very beautiful and clothed with rich vegetation, with lofty mountains eight thousand feet high near the eastern shore.
On their return they found Quartermaster Walker, who had charge of the steamer, dangerously ill, though he ultimately recovered.
They returned to Tete on the 23rd of June, and thence, after the steamer had been repaired, proceeded to the Kongone, where they received provisions from HMS “Persian,” which also took on board their Krumen, as they were found useless for land journeys. In their stead a crew was picked out from the Makololo, who soon learned to work the ship, and who, besides being good travellers, could cut wood and required only native food.
