The three lowest beds of the quarries at Ballaquane are here 
concealed by the Drift, overlying the rounded, iceworn strata of 
No. 4. With the exception of No. 6a, all the other beds are 
identical. The pebbles and breccias of the Brockrams, also, are 
practically the same. The limestone-pebbles, however, are more 
abundant, and the fossils which they contain are in a better state 
of preservation.

The conglomerates and breccias, described above, dip seaward 
(see figs. 1 & 2, p. 634, and Pl. XX XIII) under dull red sandstones, 
with breccias containing blocks great and small of red, micaceous, 
maristone and shale, with occasional pebbles of other rocks (No. 20 
of figs. 1 & 2). They form the sea-front of the Gob and of Traie 
Fogog, dipping north 8° west at an angle of 46°. Their thickness,
