DESCRIPTION OF CAVES 
from caves in very similar rock, and which they consider to 
be of great fattening value for their live-stock, the presumption 
at present is undoubtedly to the effect that the Elgon caves 
were excavated by man for a similar object. 
Anyone who realises the size of East Africa and the difficulty 
and cost of exploration work will readily understand that the 
full solution of this and many other kindred questions may 
have to wait until the country is in a position to bear the cost 
of a properly equipped geological survey. 
A great deal can, however, be done by the accumulation 
of data by officers resident in the districts, and by planters 
and farmers who reside for years in one area, and attain a more 
detailed knowledge of a particular locality than it is generally 
possible for a district officer to obtain. I desire to express 
a grateful acknowledgment of the data supplied by Messrs. 
Dobbs, Deacon, and Knight-Bruce. 
DESCRIPTION OF CAVES ON NANDI ESCARPMENT 
By P. L. Deacon 
The largest of the caves called Kiptile is situated a short 
distance from the top of the escarpment beneath the hill on 
which is a beacon. This hill is the next one to the west of 
the Gordi Juok, which is the name of a large and prominent 
rock, easily visible from Kisumu or the Uganda Railway. 
This cave is situated on a ledge some two or three hundred 
feet from the summit of the escarpment, and there are huts 
near by. It must be some 2000 feet or more above the level 
of the lake. The cave is about 20 yards long and 10 broad, 
and has a curved roof over 7 feet high in the middle. It is 
hollowed out from beneath a gigantic boulder or possibly in 
the middle of the boulder. The boulder gives the impression 
of having been eaten away to form the curve. The floor is 
solid stone, and is probably part of the same boulder. It is 
covered with earth to a depth of a foot. Flakes 1 of rock 
1 These turn out to be of a pink granite.
