TRIASSIC STRATA OF CUMBERLAND AND DUMFRIES. 379 



nesian limestone, and the underlying breccia first described 

 by Prof. Sedgwick. The St. Bees sandstone has outcropped 

 before it reached the quarry, and no trace of the White- 

 haven sandstone is seen. There are two quarries, one on 

 the east and the other on the west side of the road. In 

 the first-named the small upthrow is seen, which brings in 

 the strata to the north, as noticed at the Croft Pit and 

 Barrowmouth; and in the last-named is the greatest 

 thickness of limestone exposed. 



The strata here occur in the following descending 

 order : — 



ft. in. 



1. Hard cellular limestone, about 30 o 



2. Breccia, composed of angular pieces of slate, 



white quartz, mountain limestone, and red 



sandstone, cemented together by a red paste 8 o 



3. Loose pebbles in sand i o 



4. Strata not well seen 8 o 



5. E.ed sandstone 2 o 



6. Red and liver-coloured shales 30 o 



7. Coal o 6 



The Permian strata on the high or south side of the 

 fault dip to the S.W. at an angle of 28°. The beds on 

 the low or north side of the fault dip to the S.E. at an 

 angle of 12°; and the underlying carboniferous strata dip 

 to the S.W. at 18°. The Croft Pit and Barrowmouth 

 bear due west, about a mile from this quarry. The most 

 remarkable features observed in this quarry are the absence 

 of the soft red sandstone of Kirkby Stephen and the thick 

 red sandstone of Whitehaven, which latter rock is so well 

 seen at Barrowmouth, and was met with in sinking the 

 Croft Pit. 



The Whitehaven coal-field appears to belong to the 

 middle coal-measures, and to resemble the Canobie and 

 Ayrshire fields rather than that of Newcastle. The White- 

 haven sandstone overlies this coal-field; and no trace of 

 upper coal-measures has yet been met with in the district.
