296 NOTES ON SALT CAVES IN LUMBWA DISTBICT 
Sketch Map showing Position of Salt Caves, Lnmbwa. Caves underlined. 
Tracks Scale approximately 13 miles = one inch. 
The rock forming the walls and roof is very soft, and frequent 
falls occur. In some of the caves it is considered safer to dig 
in them by night. 
In one cave in Sotik a stone bowl of Neolithic type was 
found. No stone implements or bones have been discovered 
in any of the caves, and the softness of the walls and the con- 
tinual digging preclude any chance of finding any prehistoric 
mural decoration. 
The rock appears to be a decomposed fine volcanic ash 
or mud.
