terranean passage to a small rill, and expands into great cavities. 

 To enumerate all the caves and remarkable chasms and hollows 

 in this part of the country would be tedious and unnecessary. 

 The mountains are thoroughly cavernous. 



Geologists will be rewarded for inquiring into the remarkable 

 distribution, over limited breadths, and to elevations somewhat 

 exceeding 1200 feet, of blocks of the slaty and calliard masses 

 which fill a large space about Horton in Ribblesdale, and be- 

 tween this place and the village of Austwick. Here they are in 

 situ, occupying what, with reference to the limestone hills around, 

 may be regarded on the whole as a hollow space between two 

 elevated ranges of limestone, of which the northern is the higher ; 

 that on the south being depressed by the Craven Fault. 



From this hollow, regarded in a general sense, masses of the 

 slaty rocks have been drifted by some force of water to the south- 

 west, south, and south-east, not merely or even mainly by the 

 valleys, but over the high ground so as to rest on the limestone 

 hills above Ingleborough House and Austwick, on the elevated 

 ridges of Feizer, on the summit of Giggleswick Scar, and at still 

 greater heights on the rugged mountain over Stainforth, Lang- 

 cliffe and Settle, and eastward of this place toward the summit of 

 the road to Malham Cove. The greatest elevation reached by the 

 slaty rock, in situ, in the district, is about 1160 feet in Moughton 

 Fell, the limestone there rising over it to the height of 1404 feet. 

 It is at about the same height under the bare limestone of Long 

 Scar. The hills on to which it has been drifted southward 

 do not in general rise so high as this; but Feizer is about 30 

 feet higher, and the point on the hills over Settle which is 

 reached by the blocks, in considerable number and of great mag- 

 nitude, is not less than 1350 feet nearly 200 feet above the 

 highest part of the native rock. Still more singular is the fact 

 that the limestone of Long Scar, the hill which rises over the 

 slate to a height nearly the same as that of Moughton Fell, is 

 covered by very many of these blocks brought from below, and 

 scattered on the surface to a height of not less than 1260 feet.
