AFRICA AND ITS EXPLORATION. 
that case breaks off a heavy branch of a tree, or uproots 
a stout sapling like a boat’s mast, and belabours the 
unfortunate beast until he is glad to save himself by 
hurried flight. For this reason, the natives say, the 
rhinoceros always turns round and thoroughly scatters 
what he has dropped. 
Should a rhinoceros meet an elephant, he must ob- 
serve the rule of the road and walk away, for the latter 
brooks no rivalry ; but the former is sometimes head- 
strong, and the elephant then despatches him with his 
tusks by forcing him against a tree and goring him, or 
by upsetting him, and leisurely crushing him. 
At the distance of twenty-six miles from Kafurro we 
made our third camp near some wave-worn sheets and 
protruding humps of brown-veined porphyry, and close 
to an arm of the Uliimba lake, which swarmed with 
hippopotami. 
There were traces of water or wave action on this 
hard porphyry visible at about fifty feet above the 
present level. Some of these humps were exposed in 
the water also, and showed similar effects to those 
observed behind our camp. 
During the next two days we travelled twenty-seven 
miles south through a depression, or a longitudinal valley, 
parallel to Uliimba lake and the course of the Alexandra, 
with only an intervening ridge excluding the latter from 
our view. Tall truncated hill-cones rise every now and 
then with a singular resemblance to each other, to the 
same altitude as the grassy ridges which flank them. 
Their summits are flat, but the iron-stone faithfully 
indicates by its erosions the element which separated 
them from the ridges, and first furrowed the valley. 
Uhimba, placed by Rumanika in the charge of his 
sons Kakoko, Kananga, and Ruhinda, is sixty-eight 
miles south of his capital, and consists of a few settle- 
ments of herdsmen. It was, a few years ago, a debat- 
able land between Usui and Karagwe, but upon the 
conquest of Kishakki by Ruanda, Rumanika occupied it 
lest his jealous and ill-conditioned rival, Mankorongo of 
Usui, should do so.
