The Basement Beds can be traced round the slope of the hill - 
from Haresfield Beacon to Standish hill, and are generally | 
upwards of thirty feet thick. In the slope of the spur, half 
a mile south-west of the Beacon, they appear in immense 
blocks upwards of 10 feet thick. In the Bank above, and a 
few yards to the rear, the beds become Pisolitic, and the Pea 
grit is exposed. In the Beds near Haresfield Hill the rock 
frequently contains rather large brown grains, giving to it the 
character of a Rough Oolite. 
In the small quarry at the side of the road leading « over ie 
Horsepools Hill towards Scott’s Quarry, the junction of the 
limestone beds with the Pea Grit is shown, and the valves of 
ostrea are seen on the upper surface of the former. The 
contrast between the two formations is very striking.

The pisolitic beds in this Valley are less fossiliferous than 
elsewhere. Terbratula plicata and Pholadomya fidicula occur 
sparingly ; but in the lower beds there is a stratum full of 
Hinnites and Pecten.
