The Movements of Underground Waters of Graven. — First Report of

 Rev. E. Jones, Mr. Walter Morrison, Mr. G. Bray, Rev.

The Committee is carrying out the investigation in conjunction with a 

 Committee of the Yorkshire Geological and Polytechnic Society. 



The present is merely an interim report, as the work is still in 

 progress. 



It was decided that the first piece of work should consist of an 

 investigation of the underground flow of water in Ingleborough. This 

 hill forms with its neighbour, Simon's Fell, a detached massif, which is 

 peculiarly suitable for investigations of this nature. 



The summit of the group is formed of Millstone Grit, then follow 

 Yoredale Shales and Sandstones, the whole resting on a plateau of 

 Carboniferous Limestone.
