406 WALTON : SOME NEW SECTIONS IN THE HESSLE GRAVELS. 
Conclusion. 
It is to be hoped that further working of the pits will afford 
more information about the deeper parts of the gravel and Chalk 
cliff. The evidence of the angle of the Chalk face and the depth to 
which the cliff reaches also requires more investigation. 
With respect to the age of the gravels they may be glacial, 
in which case they must have been formed by some very local 
action, but the absence of foreign boulders, and the presence of what 
seems to be blown sand below the gravel, seems to me to point very 
strongly to the conclusion that the Hessle gravels are of the same 
age as the pre-glacial deposits banked up against the buried cliff near 
Bridlington. 
In conclusion I should like to express my thanks to Mr. Cook, 
the owner of the pits, for the facilities he has so willingly given m3 
for examining the sections.
