Notes on the Congo River. 195 
tain on the other side of the Tanganyika, full of 
deep holes, into which the water rolls moreover, 
that at the distance of over a hundred miles he 
himself heard the “ sound of the thundering surf 
which is said to roll into the caves of Kabogo.” In 
his map he ’cutely avoids inserting anything beyond 
“ Kabogo Mountains, 6,000 to 7,000 feet high.” 
The gallant young naval lieutenant’s explora¬ 
tion of the Lukuga has not yet reached us in a 
satisfactory form. He found the current sluggishly 
flowing at the rate of 1 *2 knots per hour; he fol¬ 
lowed it for four or five miles, and he was stopped 
by floating grass and enormous rushes (papyri ?). 
A friendly chief told him that the Lukuga feeds 
the Lualaba which, beyond Nyangwe (Living¬ 
stone’s furthest point, in about south latitude 4 0 ) 
takes the name of Ugarowwa: An Arab had de¬ 
scended this stream fifty-five marches, and reached 
a place where there were ships and white mer¬ 
chants who traded largely in palm-oil and ivory, 
both rare on the Congo River. And, unfortunately, 
“ the name (River) Congo was also mentioned,” a 
term utterly unknown except to the few Portuguese¬ 
speaking natives. 
At present, therefore, we must reserve judg¬ 
ment, and the only conclusion to which the unpro¬ 
fessional reader would come is that the weight of 
authority is in favour of a double issue for the 
Tanganyika, north and west.
