Upper Chalk 
j- 1. Hard blue stony Boulder Clay (base only shown). 
J 2. False-bedded sand, irregularly mixed with carbonaceous 
\ blue clay. 
{ 3. Fine loamy bluish false-bedded sand, with very few 
stones, the upper part penetrated by roots (Rootlet 
Bed). 
4. Clay pebbles, gravel, sand, and lignite, with numerous bones. 
J 5. Carbonaceous green clayey silt, full of seeds. 
\ 6. Laminated lignite and loam. 
r 7. Green and blue laminated rather carbonaceous clay. 
8. Sand with marine shells. 
[ 9. Clay as above. 
- 10. Probable position of the Chalk. 
At the time the strata were examined the beach had been 
entirely swept away by a storm, and a continuous exposure 
could be traced to low-water mark. All three divisions of the 
Forest-bed were well shown in vertical section, and the total 
thickness of the Pliocene beds must be about 40 feet. A broken 
line has been put in to show the probable position of the Chalk, 
but it may perhaps be a few feet lower. 
The Upper Freshwater Bed in the section just figured, and in 
numerous others which have been or will be described, shows a 
peculiar structure, the carbonaceous clay and sand being appa¬ 
rently contorted together. At first sight, one might suppose 
this to be connected with the contortions in the Boulder Clay ; 
but in numerous instances these small contortions in the Fresh¬ 
water Beds are cut off and overlain by evenly-bedded freshwater 
clays, proving that they originated contemporaneously with the 
deposit. A similar contorted structure is not uncommon in
