daily interesting because while it runs almost horizontal at about 

 fifty fathoms from Station 10090 to and across Jeffrey's Bank, it must 

 then dip to bottom in about seventy fathoms, the bottom salinity at 

 Station 10102 being only 33.17%o, suggesting a shoreward movement 

 of salt bottom water across the Bank. 



The next profile (Fig. 51) is parallel to the last, some 30 miles further 

 east (Station 10099, 10100, 10092). Here the slope of|the bottom is

an even one, consequently the salinity curves do not show the anoma- 

 lies noted for the profiles further west; but they agree with the latter 

 in dipping shoreward between the surface and thirty fathoms. 



The water close to the surface was slightly salter at Station 10100 

 than at Station 10092, though the former is the nearer shore; but this
