Meeting of tlie Malham Sub-Committee, Leeds Philosophical 
Hal], August 18th, 1899. 
Chairman :— Mr. P. F. Kendall, F.G.S. 
Present : — Messrs. C. W. Fennell, F. W. Branson, G. Bingley, 
J. H. Howarth, S. W. Cuttriss, J. Winskill, B. A. Burrell, 
and W. L. Carter (Hon. Sec). 
Lettei's of regret for non-attendance were received from 
Messrs. W. Morrison, M.P., F. Swann, W. Ackroyd, and G. 
Bray. 
The report of the Chemical Sub-Committee was presented by 
Mr. F. W. Branson. 
The report of the Engineering Sub-Committee was received 
from Messrs. J. A. Bean and C. W. Fennell. 
Mr. J. H. Howarth read a preliminary geological report. 
This report was supplemented by Mr. P. F, Kendall by expla- 
nations of the geological structure of Malham, and its relation 
to the flow of underground water, especially with reference to 
Grey Gill and the "Burst." 
Mr. Cuttriss reported experiments in connection with Messrs. 
Burrell and Townend at Grey Gill. A flush of water had been 
sent down from the Tarn, but no rush of water had been heard 
at Grey Gill. Mr. Winskill reported a similar experiment with 
a larger flow of water, but with similar negative results. 
Messrs. Kendall and Cuttriss c:ave interestimT; information 
about the structure of Grey Gill Cave, and the presence of water 
in it during wet seasons. 
After discussion it was decided to make excavations in the 
screes below Grey Gill Cave and at the uppermost " Burst," in 
order that chemical tests might be introduced at those points ; 
and that the Tarn water-sinks should be cleared of loose blocks 
so that the underlying rock might be examined. 
It was also resolved that a large map of the Malham area 
and diagrams of the chlorine, rainfall, and waterflow curves 
obtained during the investigations should be made for exhibition 
at the British Association (Dover) Meeting.
