MISS C. A. RAISIN ON THE 



dipping to the west of north. These are chlorite-, mica-, and mica- 

 ceo-chloritic schists alternating one with another. Bands only a 

 few feet thick or even less occur ; but the average thickness may be 

 taken as about 50 feet, though there are two masses of mica-schist 

 nearly 200 feet in thickness. With few exceptions the beds quietly 

 overlie, and after looking out carefully for evidences of repetition 

 or overfolding, I came to the conclusion that these rocks probably 

 represented a true stratigraphical succession. This series is not 

 quite so well shown along the western shore ; here a westward 

 thinning-out of the chlorite bands is suggested, unless they come 

 in partly where exposures are wanting or beds disturbed. Further 

 west, the rocks are exposed in roadside cuttings, one at Lower 

 Batson, and one to the north of it close to a phyllite outcrop, and 

 also along the shores of Batson Inlet. Here the eastern cliff has an 

 extensive development of mica-schist, but part of it, much gnarled 

 and contorted and with a changed dip, may possibly have cut out, 

 by faulting, the chlorite-band, which would otherwise have con- 

 tinued to this place from the western shore and from the lane by 

 the cemetery. The general dip is northerly or to the west of north, 

 varying from 35° to 80°, but often at about 60° to 70°. 



1. (b) Chlorite- Schist o f Scoble and of Snap es. — To the south of the 

 interbanded series, on both sides of the main estuary, a thick bed of 

 chlorite-schist has resisted the action of the water and still pro- 

 jects in the opposite headlands of " Scoble " and of " Snapes.'* 

 This chlorite-schist is closely and evenly laminated, very firm, at 

 places so compact as to be almost flinty in appearance, and has 

 altogether a squeezed look, which is confirmed by the microscope 

 slides that I have already described. 



Salcombe and Southwards. — This chlorite-schist seems to strike 

 to the northern part of the large mass on which Salcombe is built, 

 and of this there are exposures, as Professor Bonney has described, 

 as far south as an alley beyond the Eerry. Southward from this 

 alley, at an exceptionally low tide, I was able to scramble along the 

 shore, and found the cliffs, nearly to the Old Castle, to consist of 

 mica-schist, folded and contorted and nearly vertical, but striking 

 boldlv out to the north of east. As the road on the top of the hill, 

 after leaving Salcombe, cuts most of its way through mica-schist, 

 of which rock there is one quarry by the road and two on the 

 southern slope overlooking North-Sands valley, it would seem pro- 

 bable that to the south of Salcombe the hill mainly consists of the 

 mica-formation until we come to the chlorite-schist forming the 

 foundation of the Old Castle ruin and worked in the quarries near 

 North Sands. Here I would suggest the possibility of a faulted 

 junction, and of a southerly pressure overturning the chlorite and 

 some interbanded beds, and thrusting them against the mica-schist. 

 There seemed some grounds for the idea in the aspect of the cliffs 

 between the Old Castle and North Sands — the beds are disturbed, 

 contorted and broken, and form a wild scene of rugged points of cliff, 

 worn into caves, and weathered irregularly to yellows and reds, the 

 brighter colours of decomposition ; the beach is a piled-up mass of
