Quartz Rock of the Lie key Hilly &c. 
The trap is found only at the south-east extremity of the ridge 
of quartz, but the transition limestone appears once more towards its 
north extremity, at a place called Colmer’s farm, and at the distance 
of three-quarters of a mile eastwards from the quartz ; here again 
there is no section to guide our conjectures, and we find the space 
intermediate between the limestone and quartz rock occupied by an 
insulated patch of coal measures, whilst on the north-east side of 
Colmer’s farm there are quarries of old red sandstone, containing 
subordinately calcareous beds of cornstone. 
On the west side of the ridge of quartz, dividing it from the Upper 
Lickey, is a triangular valley containing coal measures, which, like 
those of Colmer s farm, have never yet been wrought on any ex- 
tensive scale ; but there is no section which affords any decided 
evidence of their dip ; the valley being inclosed by the high ridge 
of quartz projecting suddenly on its east frontier, and the still 
higher escarpment of young red sandstone which overhangs it on 
the south-west, and being terminated southwards by the union of 
these two ridges at an acute angle. From this south point the 
new red sandstone sweeps round it at a low level, touching the 
east base of the Lower Lickey up to the spot where the Birming- 
ham road emerges from the great defile, and thence retiring east- 
wards, so as to leave uncovered the coal and lime, and old red 
sandstone strata of Colmer’s farm ; so that the Lower Lickey, with 
its little group of attendant rocks, more ancient than the new red 
sandstone, is encircled on every side with an investiture of beds of 
the latter formation, abutting against and overlying, horizontally* 
the basset edges and inclined strata of the former. Beyond the 
north extremity of the Lower Lickey to the base of the Clint and 
Hagley hills, the country is composed of a fundamental rock of 
old red sandstone, having the new red sandstone ierrgularly and
