THE UNDERGROUND WATERS OF NORTH-WEST YORKSHIRE. 37 
4. The water from Outside and Black Hill which disappears 
in the pot-holes above Ha Gate. 
Note. — Re-agents have not been tried in these pot-holes. 
B. — Aire Head Springs. 
These discharge the main portion of the water disappearing 
at Malham Tarn Water Sinks. (See Malham Cove, note.) 
C. — Gordale Beck Springs. 
These discharge the water absorbed into the stream bed in 
Upper Gordale. 
D. — Cawden Burst. 
The Salt put in here reappeared at Mire's Barn. 
E. — Tranlands Beck Water Sinks. 
These discharge in the principal spring at Scale Gill Mill. 
F. — Grey Gill and Cave. 
No connection has been established between this water-worn 
cave and any outlet spring. 
The Geological Sub-Committee consider that the Tarn Sinks 
water passes near here, but this has not been proved. 
G. — Springs Below Janet's Force. 
These have not been experimented upon. 
The spring on the left bank of Gordale Beck below Janet's 
Force is probably supplied from the slopes above it. 
On the right-hand side of the main stream a strong spring 
breaks out in floods under a limestone escarpment. This is 
probably supplied from the Cawden area when the underground 
passages and fissures there are filled to high levels. 
H. — Underground Flow. 
The investigations show that within the area the main 
direction of underground flow is along the master-joints in the 
limestone.
