212 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. (Jan. 12, 
though between Stratford-on-Avon and Evesham they appear to 
contain fewer flints in proportion to the rest of their constituents 
than the deposits of a similar class occurring higher up and lower 
down the valley. The width of the beds from above Stoneleigh to 
Evesham is on an average about ? mile. Between Evesham and 
Tewkesbury they attain their maximum superficial development, 
having a width of about 1} mile. The average thickness of the 
beds, taken from measurements in eighteen different localities, is 
7 ft., their maximum thickness being 12ft. The inner margins of 
the beds form in most cases banks about 3 ft. in height above the 
surface of the modern alluvium. I have no positive evidence to 
show whether the gravel-beds pass under the latter; but from 
accounts which I have received of several borings made down to the 
basement-rock in different localities, it would appear that no gravel 
was met with. As Strickland formerly remarked, this description 
of Drift appears to be made up of the other three kinds, viz. the 
“‘quartzose, the “flinty,” and the “local” drifts. The bed resting 
on the basement-rock is in most cases composed of sand, which fills 
up the furrows occurring in the rock. 
By means of levels taken at different points across the valley, 
near Fladbury and Cropthorne, I have been enabled to group 
together the isolated patches of gravel occurring thereabouts, as will 
be seen in the following Table :-—

Some of the localities (bracketed together) are situated on the same 
plateau of gravel, whilst others are cut off from it by the valleys of 
small streams. The beds where the localities marked by asterisks 
occur do not appear to be connected in an obvious manner with 
the rest. I may therefore, perhaps, be allowed to describe them 
more in detail. 
Cropthorne Heath, where the drift-gravel containing the light- 
coloured sand is found, occupies a central position with regard to the
