320 Mr. Horner on the Mineralogy of the Mahcrn Hills. 



unstratified rocks broke through, and appeared above the surf ace; 

 and as these have been thrown up in a hne between N. and S. the 

 bearing of the elevated strata ought in general to be parallel to that 

 line, and this has been shewn to be the case : the force would be 

 greatest at the point where the unstratified rocks burst forth, and ac- 

 cordingly we find the strata there generally vertical, and in those 

 places where they dip towards the range, they seem to have been 

 raised, not only into a vertical .position, but even thrown back and 

 in some degree inverted. 



The elevation of the strata in different places, forming the low 

 hills which occin* on the western side of the range, and in which 

 the strata exhibit such remarkable changes in their position as at 

 Stony-way quarry, Eventon quarry, and the quarries near Ledbury, 

 seems to point out very distinctly, that the force has acted unequally, 

 and has had an occasional increase in different places, sufficient to 

 throw up the strata, but not so great as to raise the unstratified rocks 

 above the surface. The bending up of the ends of the strata into a 

 vertical position, where they crop out, as is represented in sketch No. 

 2, clearly shews that they have been acted upon by some violent force. 



With regard to the red sandstone of the plain on the .eastern side 

 of the Malvern Hills, it is very evident that it has been produced 

 from the disintegration of other rocks ; but it is not I think equally 

 clear that it owes its origin to the detritus of the unstratified rocks 

 of this range. For if that were the case, it would probably be found 

 on the western side as well as on the eastern,, but not a vestige of it 

 is to be seen tliere ; and instead of a level plain beginning imme- 

 diately at the foot of the hills, there would be a gradual slope 

 towards the east. It appears to me more likely that this red sand- 

 stone existed previous to the elevation of the range, and that it 

 covers stratified rocks similar to those found on the western side :
