as the Ingleborough and Peak caverns. He did not believe that 
the “ talus” had been made up of debris which had entirely 
fallen from the face of the cliffs, and which would have thus 
been altogether of limestone “breccia”; but on the contrary 
that a great part of it had been washed out from the interior 
of the cave in times of flood, carrying with the earth any 
loose bones or other light objects which lay in the cave. 
The proximity of the Craven fault might account for the 
presence of Silurian rocks in the debris, without the neces- 
sity of supposing glacial action for their conveyance. He 
did not consider it possible for the cavern to have been 
filled with debris washed in through its entrance, but rather 
the reverse.
