important being the noteworthy variations in the size and strength 

 of the Arctic discharge into the area around the Tail. We are now 

 speaking about the current which runs around the seaward edge of 

 the Grand Bank. This current quite consistently (as in previous 

 years) hugged the continental edge, i. e., the steepest part of the 

 slope as bounded by the 100 to 200 meter (55 to 110 fathoms) depths, 

 continually flooding and ebbing on this base line. It exhibited a 

 tendency at times to encroach over the Bank, but this movement was 

 always on the bottom and more marked at the Tail and for some 

 distance northwestward along the southwest slope than elsewhere-

In the main this may be attributed to the efTect of the rotation of the 

 earth which swings moving objects in the northern hemisphere to the 

 right of their paths. 



In as brief a period as two weeks a great variation was noted in the 

 size and strength of the current from the north. These pulsations 

 of the cold current, from whatever cause, react on the extreme south- 

 ern extensions of Arctic water around the Tail, and revive its in- 

 fluence from time to time, even many miles to the northwest along 

 the southwest slope. Being the extreme southern extension of the 

 cold polar water, any variation in the movement of the major masses
