DAKYNS : GLACIAL DEPOSITS. 
A Bedded Gravel of Drift Pebbles, 
on B Boulder Clay, six foot thick, 
on C Chalky Gravel seven feet thick, 
on D Boulder Clay, 
on E Sand, 
on F Boulder Clay, 
on G Sand and Gravel, 
on H Chalky Gravel, well-bedded, thinning out rapidly eastwards, 
on I Boulder Clay, 
on J Angular Chalk dehris and gravel, which dies out east of the 
valley, 
on K Boulder Clay, 
on L Sand, about six feat thick, 
on M Fine Chalkwash, in twisted lamina) about six feet thick, 
on Chalk. 
The bed M, is like the chalky rain- wash, due to subserial de- 
nudation or weathering, which is apt to clothe the bottoms and 
sides of valleys in the chalk. 
The Fig. 3 represents the curious contortions of its laminae, 
due probably to slipping. 
The sand bed E, ends abruptly under boulder clay on the west : 
it is not a well-bedded sand, but its layers seem to be twisted back 
under the boulder clay from west to east ; it would thus seem as 
if the boulder clay D, had boen deposited in a hollow, scooped out of 
the sand E, by some agent acting from west to east ; this could 
hardly have been anything else than floating ice. 
Owing to the thinning out of the other beds, the section on 
the east side of the valley consists of the following members alone, 
viz : — 
Gravel, A, 
on Boulder Clay, B, 
on Chalky Gravel, C, 
on Boulder Clay, F, I, K, 
on Sand, 
on Chalk wash, 
on Chalk. 
In the valley itself, some little way up, the section is : — 
Sand and gravel, 
Boulder Clay, 
Chalky Gravel, nine feet, 
Space hidden by tumble,
