THE LUMBWA AND ELGON CAVES 
So far as my information goes, the nest of this Eastern 
form has not been found ; but that of other species is described 
as being a domed structure, placed on the ground, and con- 
structed of roots, leaves, and twigs, and lined with fine rootlets 
and grass. The eggs are white speckled with purplish grey. 
A characteristic feature of these birds is their long tarsi 
which enable them to hop and run with great rapidity. 
These birds, though conspicuously coloured, are difficult 
to see in the gloom of the great forests. 
THE LUMBWA AND ELGON CAVES, WITH SOME 
REMARKS ON THEIR ORIGIN AND THE 
GEOLOGY OF THE REGION 
By C. W. Hobley 
In the Lumbwa highlands there are to be found an ex- 
tensive series of caves, the occurrence of which has been the 
subject of considerable discussion, and it is only of late that 
systematic examination has been possible. It is now proposed 
to record the information available up to date. The exis- 
tence of these caves was first brought to my notice by my 
friend the late H. B. Partington about eleven years ago. 
He was then the Commissioner of Lumbwa District. He 
informed me of the existence of certain caves called 
‘ Kipchebos ’ on the Kiptiget River, and stated that at 
this place there was an extensive chain of caves which, 
according to the natives, ran due south for a long distance, 
and even extended under the bed of the Sondu River. He 
recorded the fact that the natives excavated a kind of salt 
earth from these places, but pronounced no opinion as to 
their actual origin. 
During the last year these caves have formed the subject 
of investigation by Mr. Dobbs and Mr. Knight-Bruce, and 
some notes by the latter are given below, with a map of the 
area and a plan and section of one of the caves.
