542 A. CHAMPERNOWNE AND W. A. E. USSHER ON THE 
ture along the slope of Oare Hill to the fault which cuts it off some- 
where near the road to Oareford. 
From the foregoing evidences we have no hesitation in saying 
that the absence of the Lynton beds from Lucott Hill eastward is 
due to a great fault which extends from the point whence the coast 
deflects N.N.E. to the Foreland, following the East-Lynn valley 
(but cutting across the bends in the stream) as far as Oareford, 
whence skirting the north of Lucott Hill it appears to pass by 
Cloutsham Ball (name not on the map), and probably runs through 
Bickham tv Withycombe on the north of Croydon Hill. This fault 
appears to be Pre-Triassic ; but of this we cannot be certain without 
carefully examining the Triassic districts of Luckham, Wooton 
Courtney, and Withycombe. 
Mr. Etheridge advocates the existence of a fault from the Fore- 
land to Minehead*, and also suggests that the lowest beds are 
obscured by ‘“‘an extensive fault affectiug the Foreland Sand- 
stones” ‘+. The correctness of the latter suggestion we have 
endeavoured to prove; but we confine the anticlinal structure (also 
said to obscure the relations of the beds) to the higher ground com- 
posed of Foreland grits between Countesbury and Porlock, as we 
have failed to detect any signs of such structure in the Hast-Lynn 
valley. Of the fault between the Foreland and Minehead we could 
obtain no direct evidence in the limited area gone over, but, judging 
from slight indications, think the existence of such a fault, ob- 
scuring the relations of the grits of the Foreland group inter se, by 
no means improbable. 
Tur Torre VaLtey (fig. 5). 
The village of Ashbrittle is situated on dark bluish slates or 
thick shaly beds of the Coddon-Hill type, and exhibiting its cha- 
racteristic features in adjacent hill-summits to the west of the 
village. The Culm beds are exposed near Trace bridge, dipping 
S.E. at 45°. 
Whatever cleavage may at times be developed in the argillaceous 
parts of this upper series of Devon and Cornwall, it here at least 
coincides with the bedding. A line south of Coalman’s Mill, passing 
between Chequeridge and Pitt Farms, divides the Culm-shales 
(which near Pitt Farm are nearly horizontal) from the lght-grey 
slates of the Pilton series. Near Coalman’s Mill Spirifera Uri 
occurred in bluish-grey slates which dip S.E. At Stawley the 
strike has altered, giving a S.S.W. and S8.W. dip; and north of 
Stawley Parsonage, between that and Hagley Bridge, a marked 
feature is caused by reddish, greyish, and greenish grits and slaty 
beds: occasional red-brown sandy seams suggested a decomposed 
limestone. 
These beds were noticed by De la Beche (Geol. Report, Cornwall, 
Devon, &c., pp. 53 and 104) ; they contain many fossils (Spirifvra 
disjuncta, Streptorhynchus, a Pilton Crinoid, &c.). Mr. Hall com-
