Flemish Cap at the outer end of our first line of stations. The sur- 

 face was also moderately depressed over a relatively large area be- 

 tween Flemish Cap and the Grand Bank, and such a dynamic forma- 

 tion gave rise to northerly current on the west side of the Cap and a 

 southerly set on the east side of the Bank. About 50 miles northeast 

 of the Tail we located a comparatively small circular depression 

 which gave the dynamic topography in this vicinity an odd appear- 

 ance. The water between the 50 and 100 fathom curves, on the 

 northeastern part of the Bank, where the slope of the bottom is

gradual, formed the general limits of a wide gently flowing current, 

 which, however, after crossing the forty-sixth parallel, narrowed and 

 correspondingly increased in velocity. Sixty miles farther south the 

 constriction became still further marked, and the rapid flow of 1.4 

 knots per hour was recorded between the forty-fourth and forty-fifth 

 parallels along the continental edge. Casting our eyes farther south, 

 we find the inner current, however, was apparently mostly all turned 

 back before reaching the Tail, but lacking data from the southwest 

 slope permits no definite statement.
