I next examined the large sandstone quarries of Mr. Wood, 

 known by the name of the Shawk quarries, extending from 

 Shawk Foot to the hill opposite the old lime kilns. They 

 consist of fine-grained laminated sandstones of a brick-red 

 colour, and contain variegated beds, desiccation cracks, and 

 ripple marks, and in all respects resemble the Howrigg stone, 

 before described, of which they are no doubt a continuation. 

 The dip of the strata is to the north-east, at an angle of 15°, 

 and probably not less than 200 to 300 feet in thickness of 

 stone may be exposed. This sandstone is succeeded on its 

 rise by about 140 feet of red shaly marls, dipping a little east 

 of north, at an angle of 15°. Then comes in bottom of the 

 valley, near the brook, but I could not trace it going under 

 the red marls, a bed of breccia. This is composed of angular 

 pieces of mountain limestone, cemented together by a paste 

 of reddish clay containing more or less of red sand. It is seen 

 below the lime kiln, near the brook side, and the beds occur 

 in the following descending order : — 



Reddish and light-coloured sandstone 7 feet.
