It has been possible to print the data in extenso through a grant from 
the Blakeney Point Publication Fund established through the generosity 
of East Anglians interested in the work carried on at Blakeney. The 
cost of the plate has also been defrayed from this fund. 
DESCRIPTION OF PLATE XV. 
The headland as seen from the air. The various dune systems can be recognized by reference 
to Text-fig. 1. Note in particular the gradual coalesence and greater continuity of the plant covering 
as one passes from the youngest to the oldest dune systems.
