Oolite measuring about 6o feet. 
Instructive as the section in the large quarry is, it has received 
but little attention. Holl mentioned it as being much the same as that 
at Horton, and thought that the freestone was probably about 25 feet 
in thickness*; but Mr H. B. Woodward left it unnoticed in his survey 
of ‘“* The Lower Oolitic Rocks of England (Yorkshire excepted).” ? 
Higher up the hill a spring by the road-side indicates the presence | 
of the Fullers’ Earth Clay, which is also to be seen in the sides of a 
pond in the field immediately to the north of the spring and also in 
the bank bordering the road. In the latter exposure Ostrea acuminata 
is very common. The Fullers’ Earth is close upon go feet thick, and 
extends as far as the rise in the road near the Police-Station, which is 
caused by the presence of the basement-limestones of the Great Oolite. 
Hawkesbury Upton derives its water supply from the Fullers’ Earth, 
which is reached by means of wells sunk through the Great Oolite. A 
well (see fig. 2) near the Baptist Chapel is 60 feet deep. The basal 
portion of the Great Oolite in this neighbourhood does not yield 
“slates” fit for roofing purposes ; the stone-tiles seen in the village 
have been brought from a distance. 
Time did not permit of a visit to the quarry below the Monument, 
but the gentle declivity formed by the Fullers’ Earth, and the slope 
(rising towards the escarpment) which is caused by the inclined 
Inferior-Oolite strata, were pointed out.
