Tertiary Beds at Stoermoeth, 

 Kent. — Sir, — 1 enclose you a sec- 

 tion of a well sunk at Stourmouth 

 to the depth of 163 feet, and you 

 will 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 drift-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 ol 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-thiee feet pebbles 

 were 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 iu boring through it. After 

 much labour with a large peeler on 

 the boring-irons, a small hole was 

 made which still resisted the passage
