GEOLOGY OF SOMERSET. 129 
of our forefathers in many of the arts of life,-—iron 
was smelted on our western hills; for charcoal 
scorie, and fragments of crucibles, mixed with iron 
ore, are found in the Brendon hills. The almost insu- 
lated Cannington park is marked in the Ordnance 
map as one of the subordinate limestone beds of 
the Quantock hills, although so far removed from 
them. Mr. Horner in his geological survey of the 
western part of Somerset, says “ Cannington park 
is composed of a highly crystalline limestone of a 
pearl grey color, having a very close grain. I 
examined it with very great care, in order to discover 
whether it contained any organic remains, but I 
could not find the slightest trace.” * * = 
“ It is very probable that by a more minute exami- 
nation, madrepores and shells may be found in this 
limestone;; for it certainly has very much the ap- 
pearance of what is called transition limestone.” — 
We now know that corals and encrinites are readily 
found there. 
The beautifully wooded and watered combes of 
the grauwacke hills are widely known, and so are 
their lofty eminences* which command extensive 
and magnificent prospects.
