It seems probable that, prior to the deposition of the Paradozides-bear- 
ing Quarry Ridge Grits, the Black and Grey Limestones had been denuded 
at this point, but in such faulted ground the evidence is not conclusive. 
Close to Excavation No. 12, of 1907, in the disused quarry, at the 
south end of Dairy Hill, I found some fragments of grit in the soil, in- 
dicating the possibility that the grits might be found there in contact 
with the supposed Lower Comley Sandstone. 
Further excavation was therefore made at this point, and a north 
and south section, some 14 yards in length, was exposed, the beds 
dipping about 10° to the west. 
The upper part of the section shows 3 feet of bedded grit, similar 
to that of the upper portion of the Quarry Ridge Grits, resting conform- 
ably upon and graduating into some 10 feet of soft micaceous green 
sandstone, many of the beds of which are characterised by rusty 
circular spots. 
No fossils were found in this section, and it is impossible at present 
to assign these rocks to any previously described portions of the Comley 
Sandstone Series. The transition from grit to sandstone appeared to be 
complete, with no sign of either unconformity or faulting. 
In the hope of throwing further light on these Dairy Hill beds, a 
number of trial holes were made on the surface of the field and the results 
mapped in detail; but no definite opinion as to the succession could 
be formed. 
It is at present very doubtful whether the micaceous green sandstones 
belong to the Lower Comley Sandstone, and it is also uncertain whether 
the grits are part of the Quarry Ridge Grits. 
Further excavations, either here or at other spots in the Comley area, 
are required before the positions of these beds in the Comley Sandstone 
Series can be satisfactorily determined. 
Shool Rough Road Excavations. 
Previous excavations had been directed to the elucidation of the rela- 
tions between the lower part of the Paradoxides beds and the Olenellus 
zone below. ‘The excavations now to be described are in strata of a con- 
siderably higher zone, probably near the top of the Paradozides-bearing 
division of the Cambrian. 
On reference to the north-east corner of the sketch-map a road may be 
seen leading eastwards to Cardington. This is the Shoot Rough Road.! 
It ascends eastwards on ground which slopes southwards to a small stream, 
1 So called because it passes (beyond the limits of the map) between the Shoot 
Rough Wood and Shoot Rough Farm.
