they slipped out into warm water usually eddied about until they 

 were back in the cold water, actually struggling for life, as was 

 evidenced by bergs Nos. 1 and 7. 



The southerly drift was decidedly accentuated during this period 

 to a point in latitude 44° 30' N., longitude 49° 00' W., drifts as high 

 as 1.8 knots being observed in bergs along the eastern slope of the 

 Banks. An interesting condition was noted in the drift of berg No. 

 7 which was caught in an eddy of warm water along the eastern 

 slope and carried far to the eastward, finally circling to the north- 

 westward and returning to the cold water. Another interesting 

 incident of this cruise was the disintegration of berg No. 1, the 

 original "dry dock" observed by the Modoc. It had maintained its 

 shape throughout its long course; it established a record in speed, 

 making 1.8 knots per hour for a period of over 24 hours and reaching 

 a point in latitude 44° 10' N., longitude 49° 00' W., then gradually 

 recurving to the northwestward and then to the northward on the 

 Banks and there disintegrating. 



The Canadian Ice Patrol, which cooperated with the International 

 Ice Patrol, was discontinued on May 6 as the waters from Cabot's 

 Straits inland were clear of ice.
