of the Craven faults, both of which, it must be remembered, cause 
great relative depressions to the south. Though limited to the narrow 
area drawn on the map it has but one outcrop (to the south,) the 
northern edge being sunk to a great depth, and terminating against 
the plane of the south Craven fault. On the west, south, and east, 
the subjacent millstone grit rocks come to the surface, and it is seen 
beyond a doubt, especially on the south and south-west, that in this 
insulated spot, two thousand feet below the summit of Ingleborough, 
some of the lower strata of the far distant Lancashire and Yorkshire 
coalfields lie not only above the millstone grit of Penyghent and 
Ingleborough, but even above rocks usually several hundred feet higher 
than them in the scale of strata. The extent of the dislocation cer- 
tainly amounts, near the side of the southern fault, to about three 
thousand feet. The following is the section of the Burton coal strata, 
as given to me by Mr. Hodgson.
