ecological interest 
that I made a some- 
what careful observa- 
tional study of it, the 
results of which, with 
illustrative photo- 
graphs, will later be 
published.* The plain 
really begins about a 
quarter of a mile 
southwest of Eel 
Brook, where the 
single dune-beach 
becomes gradually 
two by a process 
seemingly of forking 
but in reality the re- 
sult of the gradual 
addition of an outer 
newer to an inner 
older beach. At Eel 
Brook a third ap- 
pears and north of 
that other, all by a 
similar process of al- 
most imperceptible 
addition of newer 
outer beaches, until 
at the widest part of 
the plain, there are 
considerably over 
thirty of them. The 
older of all the 
beaches is of course 
that which connects 
the Goose Lake
