BEDS OF THE ESTUARY OF THE EX. 347 



bands, dipping about 8° E.N.E ; these beds are very similar to those 

 seen on entering Exmouth by the Exeter road, and near the Cricket- 

 ground. A little to the west of the target a bed. of grey stone crops 

 out which greatly resembles that which has been worked at Clail 

 farm. As that farm lies on the dip and at a higher level than this 

 place, if it is the same bed, which is probably the case, it has been 

 thrown down to the west. Prom the target to the back of the Life- 

 boat house there is not a good exposure of the strata ; but they con- 

 sist of soft red rock and marly beds. By the footpath leading to the 

 beacon near the Cricket-ground a soft red sandy rock with much 

 false bedding intersected by clay partings and grey beds occurs ; 

 these are the same beds that occur by the roadside and at some 

 brick- works on entering Exmouth by the Exeter road, and overlie 

 soft red and grey beds. The strata which have been noticed pro- 

 bably extend inland on the strike to a fault which appears to run in 

 nearly an E.-and-W. direction near Sowden to the south of Lymp- 

 stone. The beds to the north of this fault will be noticed after the 

 beds by the sea-side have been described. 



Below the soft red-and-grey beds a conglomerate bed occurs, which 

 is well exposed at the westerly end of the Beacon ; its dip is about 

 10° E.1ST.E. ; it consists mostly of small angular and subangular 

 fragments of hard brown rock, Lydian stone and porphyry ; but I 

 have not found any specimens of granite ; and this conglomerate 

 alternates with soft red rock. 



Mr. Burridge, a builder at Exmouth, informs me that in sinking 

 for water in this conglomerate he has met with a blue clayey bed. 

 This conglomerate so closely resembles that at Cockwood, on the 

 right bank of the Ex, and also the conglomerate overlying red 

 sand rock where the road from Cofton to Kenton crosses that from 

 Staplake to Mowlish, that, though there is not full evidence to prove 

 the fact, I think there can scarcely be a doubt that the Beacon-beds 

 at Exmouth are the upper portion of those just mentioned; and 

 these I also think form the upper beds of the " Bunter." From 

 Cockwood a nearly uninterrupted section can be traced to near Tor- 

 quay (fig. 3). Between Cofton Chapel and Cofton Cross a soft red-rock 

 crops out from under this conglomerate, and may be identified from 

 Staplake Brook on the north-west to cliffs west of Langstone Point ; 

 in this sandy rock near Mowlish detached fragments of Murchisonite 

 appear ; and similar crystals are again found in a cutting by the 

 road-side about half a mile to the south-west of Cofton Chapel. At 

 a cutting near Shutton Bridge the sand, which shows much false- 

 bedding, contains small fragments of rocks ; but I have not detected 

 any Murchisonite. The small deposit of Murchisonite near Cofton 

 Chapel is nearly on the strike of that at Mowlish, and would pro- 

 perly appear in the cliff near Langstone point. I have not been 

 able to examine those cliffs closely, and the deposit is so trifling that 

 it would be easily overlooked; and I have not recognized it at that 

 point. A fault running in a northerly direction passes to the west 

 of Langstone Point ; and I have not been able to decide satisfactorily 

 the exact- position of the rocks at Langstone Point in these supposed
