THE rNDERGROUNI) WATERS OF NORTH-WEST YORKSHIRE. 
PART ir. THE UNDERGROUND WATERS OF INGLEBOROUGH. 
I. Introduction. 
On tlie completion of Part I. of this investigation, which 
dealt with the Sources of the Aire* at Malham, it was resolved 
to continue tlie investigations in conjunction with a Committee 
appointed by the British Association, of which Professor W. W. 
Watts was the Chairman. A working arrangement was en- 
tered into by wliich the Yorksliire Geological and Polytechnic 
Society agreed to carry on the work as heretofore by means 
of its own members, and to present an abstract of the results 
to the British Association from time to time through Mr. A. R. 
Dwerryhouse, M.Sc, F.G.S.. the Secretary of the B.A. Com- 
mittee for the Investigation of the Underground Waters of 
Craven, and that the complete report, fully illustrated, should 
be published in the Proceedings of the Yorkshire Geological and 
Polytechnic Society. The area of the Ingleborougli massif 
was considered to be the most suitable for the further investi- 
gations of the Committee, as it presented a complete problem 
to be considered, all the water falling on tlie higher parts of 
the mountain being gatliered into streams which fell into pot- 
holes along the line of junction of the overl3ang beds with the 
main mass of the Carboniferous Limestone, and were given out 
again in a series of underground streams and springs round 
its flanks. 
Professor W. W. Watts, on behalf of the British Association 
Committee, promised very cordial co-operation in this further 
scheme of investigation, and a Committee, in which all the 
members of the British Association Committee were included, 
was appointed by the Yorkshire Geological and Polytechnic 
Society to undertake the work. The following gentlemen 
formed the Committee : — Messrs. W. Ackroyd, F.I.C. (Halifax), 
J. A. Bean, F.G.S. (Wakefield), F. W. Branson, F.I.C. (Leeds), 
B. A. Burrell, F.I.C. (Leeds), G. H. Brown (Settle), Godfrey
