The results of extended explorations of Lake Moero, lasting for some months, are set forth in a despatch to Lord Clarendon, dated the 10th of December, 1867. From this despatch we can see that Livingstone had been misled by a similarity of name to imagine that Lake Bemba, of which he had heard years before, was the same as Lake Liemba. He now knows that Lake Liemba is only the southern portion of Lake Tanganyika; and that Lake Bemba is the lake otherwise called Lake Bangweolo; and that on his northern travels from Lake Nyassa, when he crossed the River Chambezé, he had been less than a hundred miles from this latter lake, and might have saved himself many a hundred miles of trudging had he explored it first of all. He had discovered also, that a great river, the Luapula, flows from Lake Bangweolo into the south of Lake Moero, and that at the north the waters flow out in what is called the River Lualaba. He is uncertain in his own mind what this great river Lualaba is, and whither it goes. It may be the Nile; it seems more probable that it is the Congo. It may flow into the northern portion of Lake Tanganyika, or it may flow away to the north-west. Livingstone is assured by the natives that Lake Bangweolo is only ten days distant. But he adds, “I am so tired of exploration without a word from home or anywhere else for two years, that I must go to Ujiji on Tanganyika for letters before doing anything else. Besides, there is another reason--I have no medicine.” He is satirical on the subject of the published maps, one of which tacks on 200 miles to Lake Nyassa, and another makes a river--“the new Zambesi”--flow 4,000 feet up hill! “I have walked over both these mental abortions and did not know that I was walking on water till I saw them in the maps.” The year 1868 finds him still interested in Lake Moero. His New Year’s prayer is: “If I am to die this year, prepare me for it.”
