Their head man, Massakasa declared that there must be a lake, because it was in the white men's books, and scolded the natives for speaking a falsehood. They then admitted that there was a lake. The chief brought them a present in the evening. Scarcely had he gone when a fearful cry arose from the river; a crocodile had carried off his principal wife. The Makololo, seizing their arms, rushed to her rescue; but it was too late. The expedition moving forward, on the 16th of September, 1859, the long-looked-for Lake Nyassa was discovered, with hills rising on both sides of it. Two months after this the lake was visited by Dr Roscher, who was unaware of Dr Livingstone's and Dr Kirk's discovery; unhappily he was murdered on his road back towards the Rovuma. The travellers were now visited by the chief of a village near the confluence of the lake and the river, who invited them to form their camp under a magnificent banyan-tree among the roots of which, twisted into the shape of a gigantic arm-chair, four of the party slept. The chief told them that a slave party, led by Arabs, was encamped near at hand; and in the evening a villainous set of fellows, with long muskets, brought several young children for sale; but, finding that the travellers were English, they decamped, showing signs of fear. The people of the Manjanga tribe, amidst whom they were now travelling, showed much suspicion of their object, saying that parties had come before with the same sort of plausible story, and had suddenly carried off a number of their people. To allay these suspicions, Dr Livingstone thought it best at once to return to the ship. Soon afterwards Dr Kirk and Mr Rae, the engineer, set off with guides to go across the country to Tete, the distance being about one hundred miles. From want of water they suffered greatly, while the _tsetse_ infested the district. Dr Livingstone had resolved to visit his old friend Sekeletu; but, finding that before the new crop came in, food could not be obtained beyond the Kebrabasa, he returned in the "Ma-Robert" once more to the Kongone. They found Major Sicard at Mazaro, he having come there with tools and slaves to build a custom-house and fort. After this trip, the poor "Asthmatic" broke down completely; she was therefore laid alongside the island of Kanyimbe, opposite Tete, and placed under charge of two English sailors. They were furnished with a supply of seeds to form a garden, both to afford them occupation and food. Active preparations were now made for the intended journey westward; cloth, beads, and brass-wire were formed into packages, with the bearer's name printed on each.
