that each was salter than its predecessor at all depths. The bottom 

 salinity at Station 24 is an apparent exception to this generalization; 

 but this Station, like Station 2, lies in a circumscribed trough of the 

 sea bottom, and it is probable that the salinity at the level of the en- 

 closing sill, eighty fathoms, was almost as high as it was at the bottom, 

 just as it was at Station 2. At Stations 8, 9 and 16 (fig. 23, 26) i. c.

in the coastal band of low surface salinity, the rate of increase with 

 depth was much more rapid than at the oiT-shore stations, which shows 

 of course that the effect of the fresh drainage from the land is greatest 

 at the surface; and the same is true of Stations 25 and 38 off the mouth 

 of Penobscot Bay. The curves on the off-shore banks, Piatt's, Jeffrey's 

 and German, and in the Grand Manan Channel (fig. 24) are especially
