extremely agile, and could kill a dog much larger than 
itself with comparative ease. 
We circled the eastern and northern part of the great 
cauldron, always remaining on the summit of the plateau 
at elevations varying from 2,250 to 2,300 feet. We came 
upon patches of violet-coloured and then tobacco-coloured 
sand, and also upon quantities of dark brown sand, gen¬ 
erally consolidated into easily friable rock. There were 
the usual deposits of grey ashes over the underlying 
volcanic rock which peeped through here and there. 
On June fourth we were at the Cabe 9 eira Koiteh 
(temperature, minimum 53° Fahrenheit; maximum 80° 
Fahrenheit; elevation 2,100 feet). Close to this camp, 
from an outstretching spur, I obtained another magnifi¬ 
cent view. To the east-southeast stretched from northeast 
to southwest a flat plateau, and to the east a flat, mountain¬ 
ous block with an eroded passage. Headlands branched 
off from the northern side of the ridges in a northeasterly 
direction. Between them were basins thickly wooded in 
their lower depressions. The northeastern portion of the 
flat range was almost vertical, with many angular and 
sharply pointed spurs projecting from it. 
In the centre of the greater basin, of which the others 
were details, a low, convex ridge bulged out, with three 
conical peaks — two of them at the highest point of the 
curve. Between the first and second cone two twin sub¬ 
craters were visible — evidently the two twin circles had 
formed part of the same crater — in the mountain side 
of the distant range. A third crater was some distance 
off to the southwest. 
To the southwest in the background was a fine view 
of flat highlands with huge, tower-like rocks standing 
upright upon them. Then to the south-southwest a 
regular, vertical dyke of rock stood on the top of an 
elongated, conical base.
