352 G. WAREING ORMEROD ON THE MURCHISONITE 



by E., which are very similar to beds which would lie on their 

 strike about a mile and a half distant, at the junction of the road 

 from Shillingford with the Exeter-and-Dunehideock road. A little 

 on the rise, in a cutting by some cottages at Holloway, beds con- 

 taining large rolled blocks very much resembling those seen near 

 the Teignmouth Baths occur. 



I have not been able to trace the Exminster Murchisonite beds on 

 the strike to the north of a line from Alphington to near Little 

 Bowhays ; there are not, as far as I am aware, any exposures ; but 

 for the following reason I think it probable that they do not ap- 

 pear there on the surface. For the space of about a mile from 

 the hill south of Ide, by the side of the road from Exeter to 

 Dunchideock, soft beds with fragments of rocks closely resembling 

 those just described as cropping out from below the Murchisonite 

 beds occur, dipping in a north-easterly direction; these therefore 

 lie on the strike of the Exminster-district Murchisonite beds. As 

 in the zones that have been described each has been thrown down 

 to the west as regards the next northerly zone, it is not improbable 

 that such has been the case here, and that the fourth zone reaches 

 to the igneous rocks at Pocombe, near Exeter, on its most northerly 

 point, and that the southern boundary passes to the north of Little 

 Bowhays and Alphington and south of Exeter and East Wonford. 

 The fault along the Clyst has been already mentioned. On the 

 eastern side of the Clyst, at Honiton Clyst, as I am informed by 

 Mr. Wyatt Edgell, soft sand with small detached crystals of 

 Murchisonite, like that at Bishop's Clyst, occurs. About two miles 

 and a half from Exeter, on the Sidmouth road, the soft red rock 

 with iron bands is quarried for sand to the depth of 70 feet : the 

 dip is apparently easterly ; but the false-bedding is so great that the 

 direction is uncertain. This sand is in close contiguity with, though 

 I have not seen it actually overlying, the beds of small conglomerate 

 containing Murchisonite ; these are seen in a back lane leading by 

 the west of the quarry just noticed to East Wonford, near Heavitree. 

 In a lane between the two stone-quarries at East Wonford the soft 

 fine conglomerate beds with Murchisonite are seen overlying a hard 

 rock formed of the same materials dipping about 6° E. ; this rock is 

 the same as that worked at Exminster. 



I am only aware of the exposure of the Trias at one plaee on the 

 west of Haldon ; this is at Wapple-well Quarry, near Ugbrook, and 

 by the road leading under the archway to Chudleigh. This is a 

 soft red sandstone, with iron bands and without Murchisonite, and 

 greatly resembles that near Kenton. 



In the district which has been noticed the succession of the 

 various beds is not shown so clearly along the inland zones as 

 in that by the sea-coast ; but it is believed that there is sufficient 

 evidence to show that the succession is that of which the short 

 summary was given at the conclusion of the account of the first 

 zone. The beds of the Keuper are only mentioned in the first 

 zone, as they are not seen by the Ex above Lympstone; neither 

 is the conglomerate containing fragments of limestone rocks, as
