LUMBWA CAVES

about a hundred yards, and collected specimens. This cave 
is in a most dangerous condition, and numerous rock-falls 
from the roof have recently occurred. 
The following day we left Kericho and marched south to 
Gitoi Camp, where we were met by the District Commissioner. 
This camp is on a beautiful site on a bend of the Jamjee River. 
In the afternoon we explored Gitoi Cave, which lies about a 
mile to the west. The scenery at the entrance to this cave 
is very striking ; there is a great step, about sixty feet deep, 
in the valley of the stream, due to the cutting back of a sheet 
of phonolite lava. In flood-time the river runs over this 
ledge, forming a fine waterfall. A few hundred yards back 
from the edge of this ledge, to the east, the water of the river, 
in the dry weather, all disappears into a fissure in the lava 
and reappears near the base of the cliff. We penetrated the 
cave for a distance of a little over one hundred yards, and 
saw where the natives excavated the salt rock. It was very 
wet and slimy inside. 
This cave is also entirely artificial, and the workings were 
formerly much more extensive than at present. Owing 
probably to an earth-tremor, and to the fact that extensive 
excavation had been carried on and inadequate supports had 
been left, the lava sheet settled and blocked a great portion 
of the workings. 
At the same time a crack was formed, through which the 
water of the river descended into the cave, eventually emerging 
near the foot of the cliff. This settlement is said to have 
occurred about thirty years ago, but before that the workings 
were very extensive. 
Our next halt was on the Kiptiget River. We explored 
Kipchobos Cave, which was near our camp. This again 
occurs in the valley of a small stream, and the entrance is 
under a small waterfall. The entrance is very low ; but, after 
crawling for about forty yards, we entered a great hall about 
seven feet high. From this hall, four distinct passages lead off, 
and later on they sub-divide again into passages leading in 
various directions, and of heights varying from four to six feet. 
We had not time to explore all the ramifications, but pene- 
trated about 160 yards. In one of the passages there were
