BULLETIN OF THE BUEEAU OF FISHERIES 



As stated, 1916 was so tardy a summer that the very close agreement between 

 the curves off Georges Bank for that July (station 10352) and off Cape Sable in July, 

 1914 (station 10233, fig. 144), is deceptive; equal salinities are usually attained about 

 a month later in the season off the eastern portal to the gidf than off the western. 



When the highly saline water of the ocean basin moves closest in toward the 

 edge of the continent, whether to the east or to the west of the Eastern Channel

 west slope of Georges Bank, July 21, 1914 (station 10218); B, southeast slope of Qeorgos Bank, July 22, 1914 (station

(p. 771), a very characteristic vertical distribution results, with the values highest at 

 a depth of 40 to 100 meters. Station 10218, off the southwest slope of Georges Bank 

 (our most oceanic station in temperature as well as in salinity) , showed such a dis- 

 tribution on July 21, 1914 (fig. 144), with a maximum salinity approximating full 

 oceanic value (36.04 per mille) at 40 meters, though with the surface water much 

 less saline (34.42 per mille). Stations a few miles farther east along the slope, the
