Cape Ann (p. 948), and that land water does not fan out from the coast of Maine or 
from the Bay of Fundy toward the center of the gulf. 
The evidence of salinity is positive in this connection, there being no source for 
surface water less saline than 30 per mille within the Gulf of Maine other than the 
Flo. 120.— Salinity at the surface, May 4 to 14, 1915, combined with May 4 to 17, 1920 
rivers tributary to it. Once past Massachusetts Bay, however, the May isohalines 
for 1920 (stations 20125 to 20129) very clearly show the freshest coast water (32 per 
mille in this case) spreading out from Cape Cod across the southwestern part of the 
basin about as far as Georges Bank, which seems to have bounded it at the time in 
this direction (fig. 120).
