forty-fifth parallel, and that one only to latitude 43° 54', longitude 

 48° 20', on the east side of the Bank, where it melted. When we 

 left the ice regions, June 25, there were approximately 20 bergs on 

 the northern slopes of the Grand Bank and 3 bergs near the forty- 

 iifth parallel drifting to the eastward on the northern edge of the 

 Gulf Stream. 



SUMMARY 



We now come to the summary of the season of 1927, the spring 

 and early summer of which were characterized by a number of bergs

 black line represents the actual observed numbers, while the dotted line represents the number 

 which drifts south in a normal year

The foregoing table is shown graphically by Figure 27 appended 

 herewith. The most striking fact in connection with the behavior 

 of the icebergs in the North Atlantic during the spring of 1927 was 

 their incomplete normal southward distribution. The bergs not 

 being disposed as they usually are, consequently became concentrated 

 from May 10 to June 15 in great numbers on the northern part of 

 the Grand Bank where they constituted a distinct menace to steam- 

 ships plying the Cape Race tracks. The uneven geographical dis- 

 tribution was attributed to the predominance of easterly and north- 

 easterly winds during March and April combined with the inshore 

 invasion of the warm Atlantic countercurrent.
