of Tor and Bahhacomhe Baijs, Devon. 1 Cu 



Between this place and Livermead-sands are two quarries of chocolate- 

 coloured, micaceous, siliceous, and very compact sandstone. In both a slaty 

 variety, splitting easily in the line of the laminae, which are fd!ed with mica, 

 is mixed with compact and micaceous beds, which vary in thickness from a 

 few inches to two feet. The strata are much confused, some are curved, and 

 some dip in all directions. 



In its great hardness, in its colour, in being- micaceous, and in general ap- 

 pearance, it differs entirely from the red sandstone associated witli the Exeter 

 conglomerate of the Corbons and Livermead. After passing Livermead on the 

 road to Paington, a new cut exposes a slaty variety of this rock, apparently 

 passing into grauwacke. Among the strata are a few of the more compact 

 and solid sandstones. 



Thick beds of old red sandstone are observable on the rise of the hill west 

 of Cockington, on the old road to Totness, but they are quickly covered up 

 by Exeter conglomerate, which latter continues to conceal it as far as a small 

 rivulet about half a mile east from Ockham, where it again emerges. From 

 the vicinity of Ockham to Westerland, this rock passes gradually into grau- 

 wacke slate, losing its red colour, but preserving its mica. 



At Collaton Kirkham, the same slaty and compact varieties are seen as in 

 the Cockington quarries ; their dip is E.N.E. at an angle of about 20°, the 

 beds being sometimes curved. They are much more higiily inclined in tiie 

 same vicinity. Exeter red conglomerate covers these rocks on the same hili, 

 and contains rolled pieces both of its slaty and compact varieties. The old 

 red sandstone passes into grauwacke on the high hill N.N.AV. of Paington. 



The red compact sandstone beneath the argillaceous shale at Meadfoot- 



sands, very much resembles the Cockington compact old red sandstone. At 



Hope Farm the resemblance between the two will be found most striking; 



and there can be no doubt that the limestone shale rests upon it in tlie vicinity : 



in fact, the wedge-shaped mass of old red sandstone extending from Meadfoot- 



sands and Hope Farm towards Upham, is bounded by a mantle of argillaceous 



shale. 



Sandstone and Slate of Mcadjoot-sands. 



These may almost be considered as the passage of old red sandstone into 

 grauwacke, or they may be the old red sandstone strata altered by the vicinity 

 of trap. Beneath the red grit of the Mead foot-sands is a grey, compact, fissile, 

 and very micaceous sandstone, resembling in every thing but colour, the semi- 

 schistose varieties of the Cockington red sandstones. Their angle of dip varies 

 considerably ; it is at first towards the south-west at about 65° or 70°. These 

 strata rest upon, and pass mto a slaty rock resembling the old red sandstone
