far as the moutli of the River Apsley. However this 

 may be, the greenstone appears to repose (at the point I 

 have mentioned, and which is marked on the Plan and 

 Section with the letter C) upon the coal-measures, which 

 dip to the S.E. at an angle of 12° or 13°, and range to 

 the S.W. and W.S.W. 



The point of greenstone (D), which juts into the sea 

 to the eastward of the coal, partially at least overlies 

 schistose clay with vegetable impressions, — which clay 

 stretches under and supports the coal-seams and asso- 

 ciated beds. 



To the eastward of the greenstone point (D), sand- 

 stone (E) recurs for a short space, but having suffered 

 upheaval ; for it is inclined at an angle of about 30°, 

 with numerous veins and seams of a ferruginous nature 

 traversing its substance. High on the bank it becomes 

 soft, laminated, carbonaceous, and of course dark in 

 colour, — the same which is associated with the coal at 

 (C), — and probably indicates the extension of the seams 

 from the opposite side of the greenstone point to the 

 flattish valley (F) within. 



There is, however, no natural exposition of the strata 

 absolutely to determine the question of the continuity or 

 presence even of the seams : nor could it be ascertained 

 whether, if coal actually exists at F, it is situated at a 

 depth from the surface at which it may be found prac- 

 ticable to work it. 



Where this upthrow of sandstone occurs, there is seen 

 at low water-mark a highly inclined slaty clay, and im- 

 mediately adjoining it massive granite in situ. 



This clay-slate is probably of the transition era, as the 

 beds of sandstone would appear to rest upon it uncon- 

 formably ; and it displays much of the cuboid structure, 

 and possesses the ferruginous septa so common in the 

 old metalliferous rocks.
