At the western end of the quarry there is a continuous exposure 

 of Band 1, massive limestone, somewhat sandy on the whole. A 

 thickness of not less than 15 feet is seen here. The same rock is 

 seen in places along the northern face of the quarry, where it is in 

 the main very much overgrown. The total thickness of massive 

 limestone in this quarry is probably not less than 25 feet. The dip 

 varies in amount and direction in different parts of the quarry, but 

 on the whole is 20^ or less in a south-westerly direction. 



The occurrence of three well-marked bands of celestine is 

 interesting. The presence of the mineral in this quarry was 

 originally noted by Weaver ^ . and subsequently mentioned by 

 Murchison (' Silurian System ' 1839, p. 455). 



A somewhat similar section is exposed in the eastern or Rifle- 

 Cottage quarry. The main section at the end of the quarry is 

 as follows : — 



Thickness i7i feet inches. 



Thinly-bedded rubbly limestone and shale, with nume- 

 rous fossils about 4 



Compact, rather thickly-bedded and somewhat sandy 

 limestone ; as a rule untbssiliferous, but with fossi- 

 liferous bands 15 



19 



Part of the foregoing section is also exposed on the southern side 

 of the approach to the quarry, where clay with rubbly limestone and 

 some fissile flags are seen resting upon more massive limestone of a 

 somewhat sandy character.

Limestone-debris was met with at several points along the strike 

 of the lower limestone-band near Whitfield, and a fairly well- 

 marked ridge indicating its outcrop extends for some distance to 

 the north of Whitfield House. Then, however, for a distance of 

 half a mile there is little evidence of the presence of limestone, the 

 most abundant material thrown up by ploughing or occurring as 

 debris in the fields being red sandstone.^ 



About 250 yards south of the old windmill at Falfield the 

 limestone begins again, and forms a prominent feature extending 

 as far as Falfield water-mill, and rising to a height of some 50 feet 

 above the stream which bounds it on the east. There is an old 

 quarry in red sandy limestone at the southern end of this ridge, 

 and in the neighbourhood of Falfield windmill considerable 

 exposures of limestone are seen dipping eastwards at 45°. 



Murchison (Joe. supra cit.) describes the following section as 

 occurring here. At the top : —

^ Mr. J. Harle informs us, however, that agricultural operations hare proved 

 the occurrence of the limestone-band here.
