80 DESCRIPTION OF THE COAST. 



e. 1. Black sulphureous shale, with selenite and layers of coal, formed from wood. 

 Here a multitude of fossil plants are found. 



2. The thickest of several sandstone layers. 



3. Black and white shale. 



f. Sandstone laminated. 



g. Very dark shale. 



h. Confused sandstone and shale. 



i. Alternations of thick sandstone and thicker shales. 



These oolitic rocks sink below low-water before reaching Red cliff, 

 and all the strata above it bend a little downwards, and successively 

 form scars ; but suddenly the scars are all terminated by a straight line. 

 On tracing this line backward to the cliff, we find it connected with a 

 very remarkable dislocation or slip of the strata, which may be under- 

 stood from the representation in the general section. On the left of the 

 line of this dislocation, the lower part of the Oxford clay is opposed to 

 the bottom of the calcareous grit on the right ; the Kelloways on the left 

 meets the top of the Oxford clay on the right, whilst the Kelloways on 

 the right meets the carbonaceous sandstone and shale on the left. The 

 extent of the dislocation is about one hundred and forty feet ; its 

 direction agrees with the well-known observation of miners, that " the 

 fault dips or underlies on the sunken side :" an observation to the 

 truth of which I have never seen an exception. 



RED CLIFF 



WHICH is immediately beyond this fault, is two hundred and eighty- 

 five feet above high-water, and consists of the same strata as at Gris- 

 thorpe cliff, but the carbonaceous shale at the bottom scarcely appears. 

 The calcareous grit beds at the top consist of the lower portions of that 

 rock, and beneath them are the gray alternations, which so gradually 

 change into Oxford clay, that no very distinct line can be drawn. The 

 Kelloways rock beneath is very completely exhibited, with a thickness 

 of near thirty feet, and the cornbrash with its characteristic fossils comes
