angular fragments of grauwacke from the Quantock 
hills, with scarcely a trace of limestone. The gravel 
which elevates Bridgwater a little above the allu- 
vial land, is rounded, and was probably washed 
from the Quantocks also ; it rests on the red marl, 
the immediate substratum which extends through 
so large a part of our county, underlaying the rich 
levels of Bridgwater, Brent, and Yatton, the Vale 
of Taunton Deane, as well as many of the 
smaller vallies, and our lias, green sand and other 
hills. 
Lias is an extensive formation in our district, 
resting conformably on the new red sand stone. —It

and Somerton, and the Polden hills, from Langport 
to the river Parret at Pawlet.—It makes the bed of 
the river at the passage at Combwitch, rises again 
at Hill in the parish of Otterhampton, and ex- 
tends in a narrow belt bordering the coast to Blue 
Anchor. The Jias extends no farther westward, 
except a small patch six miles beyond, at East 
Lynch.

Anchor are of lias, and its associate, red sand stone, 
which contains much gypsum between Watchet 
and Blue Anchor. They present numerous in- 
stances of disturbance in curious curvatures and 
faults, and there are good examples of bold elevated 
rocks. The features of these rocks, however, un- 
dergo frequent changes, by the waves washing away
