ON THE STOCKDALE SHALES. 



691 



1 inch thick, which is greatly hardened, 

 and is probably the band containing Mono- 

 graptus turricidatus, Barr. ; but we could 

 obtain no fossils therefrom. About 8 feet 

 of pale green shales overlie this, and then 

 several black bands like those of the crispus- 

 zone are interstratified with the pale shales ; 

 but they too have had their fossils oblite- 

 rated. 



A little to the south-west of the section 

 just described the beds are shifted some- 

 what to the north by a dip-fault, and the 

 line of outcrop of the Skelgill Beds may be 

 followed by a line of depression, along wlaich 

 runs Braidy Beck, a tributary of Mealy 

 Gill, to a pool of water known as Boo Tarn, 

 and then onward alongside the Walney 

 Scar road, and over a peat-moss to Torver 

 Beck, which is a mile and a quarter to the 

 south-west of the section last described. 

 Along the whole of this distance frequent 

 exposures of the Browgill Beds are seen 

 on the moorland ; but there is no feature 

 of any interest to record. 



Torver Beck, 



This stream runs from Goat's Water at 

 right angles to the strike of the beds. 

 West of the large flag-quarry of Tranearth 

 the depression above mentioned crosses the 

 beck, and there is certainly a strike-fault 

 across the stream here, as there is little 

 space in which no rock is exposed, and a 

 considerable amount of the Coniston-Lime- 

 stone series and nearly all the beds of the 

 Skelgill group are unseen. 



To the east of the fault the section shown 

 in fig. 7 is seen. 



Ac 3. The spinigerus-zoue is the lowest 

 band visible. The beds are much broken 

 against a minor fault which crosses the 

 stream transversely, and a dip-fault also 

 runs on the north-east side of the beck, 

 displacing the beds of the erinaceus-zone. 

 Above the small transverse fault are two 

 or three feet of the sjnnigerus-shales, 

 which are here blacker than is usually the 

 case, and contain fossils preserved in relief,
