does not invalidate the thesis of a general freshening near land, be- 

 cause the profile crosses the long-shore tongue of 32.7%o surface water 

 (Plate 2). Below forty fathoms there was practically no change in 

 salinity, depth for depth, along the profile. Comparison between this 

 profile and the one off Penobscot Bay (Fig. 50) shows that the off 

 shore w ater was slightly salter off Mt. Desert, than off Penobscot Bay,

the difference being greatest at 10-40 fathoms, where equal salinities 

 are found 10-20 fathoms deeper at the former than at the latter. 



A profile (Fig. 52) from the eastern basin (Station 10092) to the 

 coast of Maine near the entrance to the Grand Manan Channel 

 (Station 10098) shows an even more pronounced freshening toward the 

 land, down to about ninety fathoms, the curve of 33%o dipping from 

 the twenty fathom level at Station 10092, to seventy fathoms on the 

 shore slope. But below one hundred fathoms the dip of the curves
