site of battles ; as sepulchral stones, to perpetuate 
the memory of their chiefs ; and as altars, on which 
to sacrifice to tlieir gods. 
No regular stratum of the druid sandstone has 
yet been discovered in this country, and its geolo- 
gical position is still undetermined. 
LONDON CLAY. 
This formation consists chiefly of a dark blue 
clay, which in some localities includes beds of 
grey limestone and sandstone. 
Both the clay and limestone occur in Sussex : 
the former constitutes tlie flat maritime district of 
the south-western part of tlie county ; the latter 
composes groups of rocks on the coast. 
Blue Clay. 
This deposit forms the line of coast from Worth- 
ing to Christchurch, in Hampshire, extending 
from the latter place inland, by llingwood, Rom- 
sey, and Fareham ; and passing a mile or two 
south of Chichester, terminates near Wortliing, 
from whence to Brighton, the surface of the 
chalk near the coast, is covered wflth beds of loam, 
clay, brick-earth, gravel, &c.* * 
Similar stones are not nnfrequent in the large tumuli on the Downs j 
several may be seen near Lewes Race Course. It seems probable 
that the ancient Britons regarded this sandstone with superstitious 
veneration; for besitles employing it in the construction of their 
temples, kist-vaens, &c., they converted the pebbles and smaller stones 
into amulets and beads.
