Tertiary Beds at Stourmouth,

tion of a well sunk at Stourmouth 
to the depth of 163 feet, and you 
win see that it is interesting as 
showing the depth of the Thanet 
sand in this direction. I have been 
engaged in collecting and making 
drawings of fossils found in the 
Beaksbourne cuttings, and should 
any of them be novel or interesting 
I shall be glad to let you figure 
them. 
One part of the section I sent 
you deserved to have been more 
particularly described in my sec- 
tions, viz., the di'ift-valley crossing 
the sections as shown in the Beaks- 
bourne cutting ; the peat there men- 
tioned might, perhaps, have been 
more properly described as a dark 
loamy sand of organic structure and 
appearance. 
This well at Stourmouth was 
sunk to the depth of about thirty 
feet by an ordinary well curb, and at 
the depth of fifteen feet from the 
surface an iron-sandstone was met 
with ; below this a green-sand — 
very difficult to sink a well in, from 
its quicksand nature. Below this 
the well was continued by means of 
boring, a four-inch augur being 
used. At twenty-tin ee feet pebbles 
w^ere met with, small and rounded, 
of a greenish colour. Below this 
about six feet of shell-marl, the shell 
apparently exceedingly friable ; then 
we came to a blue clay, varying 
rather in hardness, but throughout 
exceedingly tenaceous, so much so 
as to require much more than the 
usual appliances to bore through it, 
and at places very plastic, and some- 
times presenting the appearance of 
septaria. At the depth of a hundred 
and thirty-nine feet flint was met 
with having the apparent flat tabu- 
lated form of flint in the chalk. 
This was shown from the difficulty 
we had in boring through it. After 
much labour with a large peeler on 
the boring-irons, a small hole was 
made which still resisted the passage 
of the augur, and kept turning the steel edge of it. Pieces of black flint
