west lies the easternmost station of Angola, Cassange: no Portuguese lives, or rather then lived, beyond the Coango Valley. The settlers informed him that eight days' or about 100 miles' march south of this position, the sources are to be found in the "Mosamba Range" of the Basongo country; this would place them in about south latitude 12° to 13° and east longitude (G.) 18° to 19°. The heights are also called in Benguela Nanos, Nannos, or Nhanos (highlands);[FN#18] and in our latest maps they are made to discharge from their seaward face the Coango and Cuanza to the west and north, the Kasai to the north-east and possibly to the Congo, the Cunene south-westwards to the Atlantic, and southwards the Kubango, whose destination is still doubtful. Dr. Charles Beke ("Athenæum," No. 2206, February 5, 1870), judged from various considerations that the "Kassábi" rising in the primeval forests of Olo-vihenda, was the "great hydrophylacium of the continent of Africa, the central point of division between the waters flowing to the Mediterranean, to the Atlantic, and to the Indian Ocean"--in fact, the head-water of the Nile. I believe, however, that our subsequent information made my late friend abandon this theory. On his return march to Linyanti, Dr. Livingstone, who was no longer incapacitated by sickness and fatigue, perceived that all the western feeders of the "Kasa" flow first from the western side towards the centre of the continent, then gradually turn with the main stream itself to the north, and "after the confluence of the Kasai with the Quango, an immense body of water collected from all these branches, finds its way out of the country by means of the River Congo or Zaire, on the Western Coast" (chap. xxii.). He adds: "There is but one opinion among the Balonda respecting the Kasai and the Quango. They invariably describe the Kasai as receiving the Quango, and beyond the confluence assuming the name of Zairé or Zerézeré. And thus he verifies the tradition of the Portuguese, who always speak of the Casais and the Coango as "suppôsto Congo." It is regrettable that Dr. Livingstone has not been more explicit upon the native names. The Balonda could hardly have heard of the semi-European term Zaire, which is utterly unknown even at the Yellalas. On the other hand, it must be borne in mind that Maxwell was informed by native travellers that the river 600 miles up country was still called "Enzaddi," and perhaps the explorer merely intends Zairé to explain Zerézeré. It is hardly necessary to notice Douville's assertion (ii. 372).
