^ol* 55-] STEFCTUKE OP THE SOUTHERN" MALYERNS. 165 



reached in excavations kindly made for me by Mr. Summers in a 

 field south-east of Beacon Farm. 



There are, secondly, a series of bosses of basalt forming tumps 

 numbered M 159a., M 108, M 249, M 248, & M 247. These 

 tumps have an elongated form. The axes of M 159a & M 108 

 are directed about north and south ; that of M 249, north-east and 

 south-west; that of M 248, north-west and south-east ; and that 

 of M. 247, east-north-east and west- south-west. These bosses 

 were supposed by Phillips to occur between the Malvern Shales 

 and the May Hill Beds, but mapping shows clearly that they are 

 situated in the Grey Shale ; for beds belonging to the latter series 

 occur between the bosses and the escarpment, as clearly seen to the 

 west of M 159a ; and, in the case of M 247, the basalt is actually 

 seen to be overlain by Grey Shale. 



It can hardly be doubted, from the analogy of the basalts farther 

 south and from the few dips seen in the northern district (for 

 instance, at M 159), that the direction of these short ridges of basalt 

 marks that of the strike of the beds. The separate exposures, 

 moreover, appear to be all approximately on the same horizon, with 

 the possible exception of M 247, which may mark a higher 

 horizon. 



In this northern district, then, a curved igneous band, consisting 

 of basalts (and diabase) extends from Beacon Farm almost as far 

 ^s Castle Coppice, and, judging from the configuration of the ground, 

 it is connected with the diabase in the main road (M 106) by a 

 concealed mass of similar rock. This band is undoubtedly a 

 northern prolongation of the Coal Hill igneous band, which it 

 resembles in being overlain and underlain by Grey Shales con- 

 taining Dictyonema sociale. 



The eastern part of the Bronsil district is occupied by May 

 Hill Sandstone, allusions to which may be found in the works of 

 Phillips and Holl. The May Hill Beds at the north-eastern corner 

 of the area are apparently a south-easterly continuation of those 

 which form the north-western corner of Midsummer Hill. The 

 sandstone in this locality, like that elsewhere in the Bronsil 

 district, is nowhere actually exposed, and can be reached only by 

 excavations. 



This sandstone is evidently separated from that forming the 

 escarpment by a fault, which probably runs along the bottom of 

 the valley traversing Castle Coppice ; for the beds exposed in the 

 escarpment on the western side of the valley are the basal beds of 

 the series, and dip at a considerable angle west-north-westward, 

 while those under consideration are grey beds belonging to a higher 

 part of the formation. 



A second faulted patch of May Hill Sandstone occurs to the 

 south. An excavation (M 192) close to a spring revealed Llan- 

 dovery rock with Stricklandinia sp., and a second excavation 

 (M 113) made a little to the north-west of the first furnished
