He is a little better a fortnight later, and anxious to move on. But whither? He had intended to follow the lake to the north-west; but the road seems barred by the Mazitu, who are out for plunder. He has heard of Lake Moero, which lies to the west some two hundred, or two hundred and fifty miles. Is it not possible that this lake may be the common source of the Congo and the Nile? The geographical problem is most persistent, and he cannot be satisfied to leave Lake Moero unexplored. On the first day’s march he has another fit of insensibility, but this does not constitute an argument for delay. He reached the village of a chief Chitimba, only to find that the country between him and Lake Moero is the scene of a small war, which would involve “a long détour round the disturbed district.” He decides to wait events, which turns out to be a tedious business; but the Arabs are kind to him, and the enforced leisure is probably beneficial. His diary is full of descriptions of the cruelties inflicted by the slave-trade. In all, he was detained at Chitimba’s village nearly three months and a half. In his onward march he visits the famous Nsama, with whom the war has been waged, and is again laid up with illness in that neighbourhood. After this, he crosses the Chisera and the Choma, and then ascends the high lands between the rivers and the northern part of the lake. It is exhilarating travelling here, for Livingstone is always pleasantly excited by beautiful and hilly scenery which brings back memories of Scotland. But, alas! “the long line of slaves and carriers” is a frequent incident in the march. On the 8th of November, he reaches Lake Moero, “which seems of goodly size, and is flanked by ranges of mountains on the east and west.” There he sleeps in a fisherman’s hut, for the lake abounds in fish, the fishermen enumerating thirty-nine varieties. The end of November finds him at the town of Casembe, where he meets an Arab trader, Mohamad Bogharib, “with an immense number of slaves,” who gives him a meal--the first honey and sugar he had tasted for fourteen months--and is useful to him in many ways. The chief also is civil to Livingstone; but has been guilty of hateful barbarities, as the mutilated arms and ears of many of his people bear witness. Livingstone looks with disgust on the executioner who carries sword and scissors for his horrible work. The people generally are more savage than any he has seen.
