KIBO AND KIMAWENZI.

with my telescope the interesting summits of Ivibo and 
Ivimawenzi. The latter is apparently a mass of black 
and broken rocks, culminating in numberless fantastic 
pinnacles and needle-points partially covered with 
snow, and forming an almost unique study in black 
and white. Any ascent appeared to me to be quite 
impracticable. Ivibo, on the other hand, is of much 
greater circumference, dome - shaped, and certainly 
practicable up to about 18,000 feet, or perhaps even 
a little higher. Beyond that elevation I think it 
would be impossible to climb by either the southern, 
eastern, or north-eastern sides, as any passage is 
apparently barred by abrupt cliffs and precipices, 
and, still higher up, by almost perpendicular walls of 
solid ice and snow, some hundreds of feet in height, 
before it again gradually slopes upwards for a few 
hundred feet towards the mouth of the crater. The in¬ 
tervening shelving spaces below the glacier are covered 
with loose shale and volcanic matter. 
I may lay claim to having ascended beyond the 
first snow-line, as there were two small patches of 
snow on this hill about a hundred feet immediately 
below me. The saddle between Kima and Ivibo 
is a sloping plateau, some four miles wide from the 
points where Ivibo on the one side and Ivimawenzi 
on the other begin to rise precipitously. On this 
plateau are, scattered about in all directions, high 
blocks of rock, many weighing several hundredweight, 
which suggested the idea that Ivibo must have suf¬ 
fered badly from indigestion before getting rid of
