The travelers had got as far as the river Loangwa (of Nyassa), when a halt had to be called. Some of the natives had been ill, and indeed one had died in the comparatively cold climate of the highlands. But nothing would have hindered Livingstone from working his way round the head of the lake if only time had been on his side. But time was inexorably against him; the orders from Government were strict. He must get the "Pioneer" down to the sea while the river was in flood. A month or six weeks would have enabled him to finish his researches, but he could not run the risk. It would have been otherwise had he foreseen that when he got to the ship he would be detained two months waiting for the rising of the river. On their way back, they took a nearer cut, but found the villages all deserted. The reeds along the banks of the lake were crowded with fugitives. "In passing mile after mile, marked with the sad proofs that 'man's inhumanity to man makes countless thousands mourn,' one experiences an overpowering sense of helplessness to alleviate human woe, and breathes a silent prayer to the Almighty to hasten the good time coming when 'man to man, the world o'er, shall brothers be for all that.'" Near a village called Bangwé they were pursued by a body of Mazitu, who retired when they came within ear-shot. This little adventure seemed to give rise to the report that Dr. Livingstone had been murdered by the Makololo, which reached England, and created no small alarm. Referring to the report in his jocular way, in a letter to his friend Mr. Fitch, he says, "A report of my having been murdered at the lake has been very industriously circulated by the Portuguese. Don't become so pale on getting a letter from a dead man."
Reaching the stockade of Chinsamba in Mosapo, they were much pleased with that chief's kindness. Dr. Livingstone followed his usual method, and gained his usual influence. "When a chief has made any inquiries of us, we have found that we gave most satisfaction in our answers when we tried to fancy ourselves in the position of the interrogator, and him that of a poor uneducated fellow-countryman in England. The polite, respectful way of speaking, and behavior of what we call 'a thorough gentleman,' almost always secures the friendship and good-will of the Africans."
On 1st November, 1863, the party reached the ship, and found all well. Here, as has been said, two months had to be spent waiting for the flood, to Dr. Livingstone's intense chagrin.
While waiting here he received a letter from Bishop Tozer, the successor of Bishop Mackenzie, informing him that he had resolved to abandon the Mission on the continent and transfer operations to Zanzibar. Dr. Livingstone had very sincerely welcomed the new Bishop, and at first liked him, and thought that his caution would lead to good results. Indeed, when he saw that his own scheme was destroyed by the Portuguese, he had great hopes that what he had been defeated in, the Mission would accomplish. Some time before, his hopes had begun to wane, and now the news conveyed in Bishop Tozer's letter was their death-blow. In his reply he implored the Bishop to reconsider the matter. After urging strongly some considerations bearing on the duty of missionaries, the reputation of Englishmen, and the impression likely to be made on the native mind, he concluded thus: "I hope, dear Bishop, you will not deem me guilty of impertinence in thus writing to you with a sore heart. I see that if you go, the last ray of hope for this wretched, trodden-down people disappears, and I again from the bottom of my heart entreat you to reconsider the matter, and may the All-wise One guide to that decision which will be most for his glory."
