tonbury, Brent, &c.* Fossils are very abundant 
in these beds. 
The upper or green oolite is extensively worked 
in the vicinity of Bath. 
The green sand hills called Black Down, are a 
striking range, bordering the county, south of 
Taunton and Wellington; their peculiar outline 
attracts the eye from distant parts of the county. 
Although there is very much that is interesting 
in these {wo last formations, we must pass lishtly 
over them. 
The alluvial lands of our county are very exten- 
sive, and proverbially rich. The extended levels 
opening on the Bristol channel have doubtless been 
estuaries in recent geological time. Sand banks, 
parts of former sea-barriers, elevate above the sur- 
rounding land Westonzoyland, Chedzoy and other 
villages, and their valuable corn fields; they prove 
their comparative late formation by the multitudes 
of shells which they contain, all of species now 
living on our coast, and many of them retaining 
their colour and markings. The lower part of the 
humerus of a young mammoth has been found at 
Chedzoy. 
Under the rich soil of our levels, beds of peat 
occur at different depths; they also form the sur- 
face of extensive tracts of our county. The Sedge- 
moors are fast emerging from their morass-like 
state, and cultivation is spreading widely over them. 
* These require further examination ; perhaps upper lias may be here.
