The Movements of Underground Waters of North-west Yorkshire.— 
Fifth Report of the Committee, consisting of Professor W. W. 
Warts (Chairman), Mr. A. R. DwerryHousE (Secretary), Pro- 
fessor A. SMITHELLS, Rev. E. Jones, Mr. WaLTerR Morrison,

Professor P. F. KENDALL, and Dr. J. E. Marr. 
Tae Committee are carrying on the work in conjunction with a committee 
of the Yorkshire Geological and Polytechnic Society. 
It will be remembered that at the Southport meeting the Committee 
reported that the work of tracing the streams sinking on the slopes of the 
Ingleboro’ massif was complete, with the exception of a few small streams, 
These have now been traced, and the work of the Committee is there- 
fore completed, with the exception of the boreholes at Turn Dub men- 
tioned below. 
The work done during the current year consists of tracing the fol- 
lowing streams by means of fluorescein. 
East Side of Ingleboro’. 
1, The stream sinking at P 14,' near the shooting-box on the Allot- 
ment, which had been unsuccessfully tested on several previous occasions, 
was found to issue at Austwick Beck Head (S 28). 
2. A small stream to the north of last, sinking at P 18, passes by 
P 19, where the fluorescein was visible, to S 40, there joining the water 
from P 25 and P 26, previously tested. 
3. The small stream sinking at the ‘Washfold’ (P 52) on Park Fell 
was found to communicate with the channel from Alum Pot to Footnaws 
Hole (S 65), where the water was strongly coloured three days after the 
fluorescein was introduced at P 52. Footnaws Hole, as has been pre- 
viously shown, discharges in normal weather at Turn Dub (S 67). 
West Side of Ingleboro’. 
4. P93. The water from a group of small streams near Douk Cave 
on Fenwick Lot, Souther Scales Fell, flows underground along the direc- 
tion of the master joints in the limestone, and issues at S 106a, a small 
spring below Eller Keld. 
5. The water from P 97 and P 98 on Souther Scales Fell flows to a 
small spring and cave known as Far Douk, but not marked on the 6-inch 
Ordnance Map, P 95a, and then again goes underground to join the 
river, somewhere on its underground course from Weathercote Cave to 
God’s Bridge. 
6. P 101 and P 102 on Black Shiver Moss receive the waters of two 
small streams, the flow being to the lower end of Mere Gill Hole, where 
it joins the waters of Mere Gill, and again goes underground. The further 
course of this stream has been described in a previous report. 
7. P 102a on the eastern edge of Lead Mines Moss, not marked on 
the 6-inch map, receives a small stream in wet weather only. 
This, on being tested with fluorescein, was found to communicate with 
S 116 near the ‘ Engine Sheds’ at the Ingleton Granite Quarries.
