that the cold current was running swiftest along the east side of 

 the Bank at the rate of 1.4 knots per hour, but it decreased to 0.7 

 knot 60 miles farther south at the Tail. The inshore set (Labrador 

 current) curled around the Tail and flowed northwestward parallel 

 with the continental edge, a distance of 150 miles, as far as our 

 observations extended in that direction. Reaching that locality, a 

 great portion of the current eddied offshore and back to the east- 

 ward, forming a vast anticj^'clonic vortex off the southwest slope. 

 The most rapid rate of flow was 1 knot, located southwest of the 

 Bank, as shown on Figure 50, page 110. The easterly moving water 

 masses were split by a clockwise eddy when they reached a point

Fig. 52.— Set I. Distribution of light and heavy water on the surface of the sea 



southeast of the Tail, but just to the northeast of this point the 

 branches rejoined. The northeasterly coimterset was only 25 miles 

 off the eastern edge of the Bank in latitude 44°, but it was weak — 

 0.2 of a knot per hour. 



The distribution of cold water, as shown by Figure 51, page 110, 

 is good evidence wliich supports the general scheme of circulation 

 calculated and portrayed on Figure 50, page 110. The cold water 

 from the north was transported to the Tail and thence along the 

 southwest slope of the Grand Bank as far as om- observations in 

 that direction extended. The shape and position of the shaded area 

 of water less than 1° C. (fig. 51, p. 110), clearly indicates that this cold 

 water after being brought to the region of the southwest slope was
