Older Palgeozoic Rocks extending beneath the Millstone Grit, the 

 Yoredale Rocks and the Mountain Limestone that Wilbert Fell 

 itself consists of; and this must be as much as, if not more than, 

 two thousand feet. That is to say, at that point the Post-Carbon- 

 iferous part of the fault there has a downthrow to the east of not 

 less than two thousand feet. 



Now, as we follow the surface of the Howgill Fell Silurian rocks 

 northward to the town of Ravenstonedale, we find the Mountain 

 Limestone beginning to come on the edges of the older strata ; 

 and, instead of lying at a comparatively low angle, as they are 

 known to do on the east side of the Faults, they here come on 

 with a high angle of dip. This dip amounts to an average dip of 

 about eight or nine degrees — possibly an average of ten. As a 

 consequence, although the local thickness of the Mountain Lime- 

 stone with the beds below it, altogether amounts to between two 

 thousand and two thousand five hundred feet at this part, by the 

 time we have got as far north as Kirkby Stephen the very top is 

 reached. Now this horizon, as I have more than once before 

 remarked, goes on at about the same general level on the other 

 side of the line of disturbance. Consequently, when the top of 

 the Mountain Limestone on one side of the fault is brought into 

 contact with the top of the Mountain Limestone on the other, 

 there is clearly no vertical dislocation, even though the actual 

 fissure and the accompanying disturbances remain to attest to the 

 existence of the fault itself But the dip to the north continues as 

 we traverse the country on the north-west side of the faults in the 

 direction of Brough ; so that the Yoredale Rocks, and then the 

 Millstone Grit, come down bed after bed into the low ground at 

 the foot of Stainmoor, and the throw of the Great Faults, instead 

 of being, as at first, down south-easterly, has changed sides, and is 

 now rapidly increasing in amount on the north-westerly side. 



North of the Bela, in the neighbourhood of Kaber, the faults 

 become very complicated, and the downthrown rocks, which are 

 very greatly disturbed, begin, as a whole, to dip more and more 

 towards the east, and the angle of dip gradually augments from 

 that of a few degrees up to one of sixty degrees or more. This
