572 Mr. Horner on the Geology of the 



Anchor, except at those places where the brooks at Little Stoke 

 and Donniford fall into the sea. From the place where the cliffs 

 begin to that part of the coast which is immediately below Perry 

 Court, they are entirely composed of the lyas strata, and that is 

 the most eastern point where the red rock appears in the cliff. 



§ 40. In the whole course of this part of the shore the strata 

 hardly ever preserve a uniform bearing or dip for the space of a 

 quarter of a mile, but are liable to constant changes dipping in 

 every possible direction. It would be impossible, by any descrip- 

 tion of the particular instances of disturbance, to give an intelli- 

 gible representation of the extraordinary appearance of this coast 

 on walking over it at low water : I cannot convey a better idea of 

 it than by comparing it to the great waves of a sea suddenly con- 

 solidated. These waves are now broken in many directions, and 

 exhibit various sections of their Internal structure. That the con- 

 volutions took place when the rocks were in a plastic state Is highly 

 probable, for the curve Is complete, in many cases, without a 

 fracture. Besides these curvatures there are In many places along 

 the cliff, and particularly between Shurton Bars and Little Stoke* 

 instances of those slips in the strata which are of such frequent 

 occurrence in the coal districts. Sometimes these slips are only of 

 a few Inches, in general they are of a few feet, but they are 

 sometimes so great that In a cliff of 100 feet high there is a com- 

 plete change in the nature of the strata on each side of the slip ; 

 there being on one side of k a numerous alternation of limestone 

 and slate clay strata, and on the other only slate clay with a very 

 few thin beds of limestone. In general I found the line of the 

 slip filled by calcareous spar, sometimes only a few lines in breadth 

 and rarely exceeding a few Inches, and in many instances as I have 

 already noticedj I found the matter of the vein penetrating the
