The river presents the same appearance of low banks without trees as we have remarked it had after we came to 16d 16', until we arrive at Libonta (14d 59' S. lat.). Twenty miles beyond that, we find forest down to the water's edge, and tsetse. Here I might have turned back, as no locality can be inhabited by Europeans where that scourge exists; but hearing that we were not far from the confluence of the River of Londa or Lunda, named Leeba or Loiba, and the chiefs of that country being reported to be friendly to strangers, and therefore likely to be of use to me on my return from the west coast, I still pushed on to latitude 14d 11' 3" S. There the Leeambye assumes the name Kabompo, and seems to be coming from the east. It is a fine large river, about three hundred yards wide, and the Leeba two hundred and fifty. The Loeti, a branch of which is called Langebongo, comes from W.N.W., through a level grassy plain named Mango; it is about one hundred yards wide, and enters the Leeambye from the west; the waters of the Loeti are of a light color, and those of the Leeba of a dark mossy hue. After the Loeti joins the Leeambye the different colored waters flow side by side for some distance unmixed. Before reaching the Loeti we came to a number of people from the Lobale region, hunting hippopotami. They fled precipitately as soon as they saw the Makololo, leaving their canoes and all their utensils and clothing. My own Makalaka, who were accustomed to plunder wherever they went, rushed after them like furies, totally regardless of my shouting. As this proceeding would have destroyed my character entirely at Lobale, I took my stand on a commanding position as they returned, and forced them to lay down all the plunder on a sand-bank, and leave it there for its lawful owners. It was now quite evident that no healthy location could be obtained in which the Makololo would be allowed to live in peace. I had thus a fair excuse, if I had chosen to avail myself of it, of coming home and saying that the "door was shut", because the Lord's time had not yet come. But believing that it was my duty to devote some portion of my life to these (to me at least) very confiding and affectionate Makololo, I resolved to follow out the second part of my plan, though I had failed in accomplishing the first. The Leeba seemed to come from the N. and by W., or N.N.W.; so, having an old Portuguese map, which pointed out the Coanza as rising from the middle of the continent in 9 Deg. S. lat., I thought it probable that, when we had ascended the Leeba (from 14d 11') two or three degrees, we should then be within one hundred and twenty miles of the Coanza, and find no difficulty in following it down to the coast near Loanda. This was the logical deduction; but, as is the case with many a plausible theory, one of the premises was decidedly defective. The Coanza, as we afterward found, does not come from any where near the centre of the country.
