CAVES OF REFUGE. 
proceed along the southern shores of Lake Bangweolw, 
which, being in latitude 12 J south, the course will be duo 
west, to the ancient fountains of Herodotus. From them 
it is about ten da 3 's’ north to Katauga, the copper mines 
of which have been worked for ages. The malachite ore is 
described as so abundant, it can be mentioned by the coal 
heaver’s phrase, “practically inexhaustible.” 
About ten days’ northeast of Katauga, very extensive 
underground rock excavations deserve attention, as very 
ancient, the natives ascribing their formation to Deity 
alone. They arc remarkable for all having water laid on in 
running streams, and the inhabitants of large districts can 
all take refuge in them in case of invasion. Returning 
from them to Katauga, twelve days’ north-northwest, take 
to the southern cud of Lake Lincoln, I wish to go down 
through it to the Lomani, and into Webb’s Lualnba and 
home. I was mistaken in tho information that a waterfall 
existed between Tanganyika and Albert Nyanza. Tangan- 
yika is of no interest, except in a very remote degree, in con- 
nection with tho sources of the Kile. But what if 1 am 
mistaken, too, about the ancient fountain ? Then we shall 
see. I know the rivers they are said to form — two north 
and two south — and in battling down the central line of 
drainage, the enormous amount of westing caused me at 
times to feel as if running my head against a stone 
wall. It might, after all, bo the Congo ; and who would 
care to run the risk of being put into a cannibal pot and 
converted into a black man for anything less than the grand 
old Nile? But when I found that Lualaba forsook its 
westing and received through Komolondo. Bartle Frore’s 
great river, and that afterwards, further down, it takes in 
Young’s great stream through Lake Lincoln. I ventured to 
think I was on the right track. 
Two groat rivers arise somewhere in the western end of 
the watershed, and flow north — to Egypt. (?) Two other 
great rivers rise in the same quarter, and flow south, as tho 
Zambesi or Liambai, and the. Kafue, into Innar Ethiopia. 
Yet I speak, with diffidence, for I have no affinity with an
