The frequency of the symbols 
indicates approximately the abun- 
dance of the species. Only the 
horizontal distribution along the 
beach can be shown with any 
accuracy, owing to the crowding of 
the symbols in many areas. The 
vertical distribution can be learned 
more exactly from the text. 
The general distribution of Zostera 
and Spartina glabra is shown in 
black. In the case of the former 
the abundance of scattered plants 
outside the area of greater density 
is indicated by the proper symbol 
printed in green. 
The distribution of these plants 
on the marsh is shown on Plate XI.
