faulted up all along its strike. This fine valley is deeply paved 

 with the Dolomitic (TipnoUerJ conglomerate, which here and 

 there is seen to occur in patches through subsequent denudation 

 (to be hereafter noticed). The deep Porlock and Luckham 

 Yalley ending at Diddon is probably synclinalled and faulted. 

 At Diddon the beds of Grabbist Hill dip north-east, at Timber- 

 scombe, half a mile across the valley, they dip south-west 

 continuously, thus showing that this deep and narrow valley, with 

 the parallel one of Minehead and Bratton, divided by Grabbist 

 Hill, 906 feet high, are in much disturbed ground, the distorted 

 or disturbed conditions of which are hidden by the newer over- 

 lying and flanking New Red Sandstone, with its conglomerate 

 and patch of Rhsetic. They were gulphs or fiords in the New 

 Red period, whose tidal action had power sufficient to lay down 

 the conglomerate in considerable thickness throughout what 

 are now narrow valleys. 



One of the finest examples of ])arallel faults and their effects 

 is shewn west of Watchett, see section YI. Looking due east, 

 near Little Silver, the Planorbis shales, Ostrea beds. White Lias, 

 Black shales of the Upper Rhsetic and the Tea-Green passage 

 shales are wedged in between two masses (one in reality) of 

 New Red Marls, the northern wedge-shaped mass has, seaward 

 of it, a repetition of those beds to the south ; the sea having 

 destroyed the Rhsetic series above its level — Watchett standing 

 between these two parallel faults. 



At the Warren, more westward, two equally remarkable north 

 and south faults occur, disturbing a large mass of the cliffs and 

 affording clear evidence of their original and present position. 

 Sec. 6. 



The two faults in section V. describe a Y shaped area between 

 their inner sides, where the Rhsetic series are wedged in; on the 

 west the upper members are denuded. It is a great exhibition 

 of force, and cause and effect ; such indeed is the whole cliff ; a 

 ground plan of the Watchett coast, and foreshore would appear 

 impossible upon paper. 



The grand chff sections east of Quantocks Head [where they 

 are both anticlinaled and faulted,] exhibit all the Bueklandi and
