A continuation of the study of the deeper waters was Dre 
cluded at Woods Holl by reason of the shallowness of he 
ocean in the vicinity of this port. The shallow continental 
platform which skirts the eastern edge of the U. S. is here at 
its greatest width and the broad shoals of Nantucket are even” 
out of sight of land. The conditions however were favorable 
for the investigation of marine forms in general. | 
Woods Holl is situated at the extremity of a narrow neck 
of land that pushes southward from the southernmost point of 
the Cape Cod peninsula. This narrow land strip is continued 
seaward in the chain of the Elizabeth Islands and divides” 
Buzzard’s Bay, an almost land-locked sea, from Vineyare 
Sound. This latter body of water separates the mainland 4 
the Elizabeth Island chain from an outer range of islands com — 
prising Nantucket, Martha’s Vineyard and others. 
The soil of the mainland is of a sandy nature and the ae
