where it is but a few yards wide, it rapidly broadens northward 
until it reaches some half a mile across, and then narrows 
again towards its northern 
end, which is also the 
northernmost point of the 
island. Though nearly 
level as a whole, it is by 
no means flat, for it is com- 
posed of a series of ap- 
proximately concentric dune 
beaches, which, two or three 
in number at Eel Brook, in- 
crease to over forty opposite’ 
Lac Frye. In height these 
dune beaches vary from 
two to five or six or even 
seven feet (0.6-2™) and in 
breadth from eight or ten 
up to forty or fifty paces. 
At its widest part, which 
comprises some thirty or 
more of the beaches, new 
ones are plainly being 
rapidly added, while at its 
northern end the entire 
plain is being washed away 
by the sea, which is cutting 
sharply across the ends of 
the old beaches. About 
two-fifths cf the plain, in- 
cluding the older parts next 
the upland, are forested; 
about two-fifths, including 
all the outer and newer 
parts, are open, clothed only 
by the waving beach grass ;
