is not continuous with that on the eastern face of North Hill, as 

 depicted in Holl's map. We may suppose that the Archaean rocks 

 in Cowleigh Park have been thrust on to the inverted May Hill 

 Beds, in much the same way as the Archaean has been thrust on 

 to various members of the Silurian along the Malvern Eange ; but 

 in the present case the overthrust and overfolding have taken place

from the north-east (fig. 11). If the direction of the fault be con- 

 tinued south-eastward it will meet the Archaean of North Hill 

 immediately south of an old well sunk many years ago near the foot 

 of the slope. The strata met with in this well (see fig. 12, p. 158) 

 were examined by Mr. (now the Rev.) G. E. Mackie. 1 The section 

 is tabulated as follows, in descending order : — 



Feet. 



1. Surface-gravel (hill-debris) 12 



2. Red crumbling marl with small pebbles 24 



3. Coarse grey-and-red sandstone and conglomerate 16 



4. Very hard breccia of quartz-pebbles in a red-and-jellow 



matrix 6 



5. Black Cambrian Shales with Olenus, Conocoryphe, Lingu- 



lella, etc 9 



A boring carried 22 feet below the bottom of the well passed 

 through 9 feet more of the Black Shales, and then through 13 feet 

 of red rocks, apparently a repetition of beds 2 & 3. The rocks 

 dipped at an angle of 50° (direction of dip not stated).
