quarry, we pass on to the other members of the Lower Greensand 
found in tlie Maidstone district. Below the Kentish rag beds comes 
the Atherfield clay. This formation is passed through in the railway- 
cutting at Tetsom, where it is seen basseting out from beneath the 
hills of ragstone. A list of the fossils of this division of the Lower 
Cretaceous rocks has been published by Dr. Eitton in the Transac- 
tions of the Geological Society, vol. iv. part 2, 1836. 
The junction with the AV^eald clay may be clearly traced at this place, 
and laminated beds of fawn-coloured stone are met, containing seams 
of small Pakidinse, Cyprides, 
teeth and bones of fish, and Section or 
also the elj'tra, or wing-cases, 
of beetles. In 1851, the Weald 
clay was met with in digging 
a drain in St. Faith's Street 
(Maidstone). At a depth of 
from eight to ten feet, a series 
of slate-coloured slabs of stoue 
was found, in which Wealden 
fossils (Cypris) were to be seen 
lying in close proximity. The 
edges of these slabs were round- 
ed, and a ferruginous border of 
a quarter of an inch enveloped 
the stone. 1 conjecture that 
it is this border which is found 
in a broken and waterworn 
state, mixed with the drift, at 
various places round Maid- 
stone. 
In 1847, Mr. Fish com- 
menced a boring for the sup- 
ply of water for his brewery. 
"Wishing to obtain a supply 
free from the acidity of de- 
cayed vegetable matter, he set 
out with the intention of going 
sufiiciently deep to secure that 
result. After passing through 
about twelve feet of the debris 
of the ancient Med\vay,hecame 
to a dark-blue clay of soapy 
texture, with veins of greyish 
white. No fossils were ob- 
tained. In this clay a supply 
of water was obtained, but it 
was not equal to the demand, — the water, turbid from the clay which 
it held in suspension, requiring a long time for its precipitation.
