The next day, April 20, the Pontchartrain scouted south and east 

 around the Tail of the Banks in order to locate a growler reported on 

 the Tail on the 19tli and particularly to relocate the berg last seen by 

 the patrol vessel April 18 in latitude 42°55' N., longitude 49°49' W. 

 The growler was not found, but the berg was located in latitude 42°37' 

 N., longitude 50°51' W., having drifted 55 miles in the preceding 2 

 days in almost exact accordance with the current chart. April 21 to 

 25, the Pontchartrain remained with this berg as it moved west- 

 northwest in the cold current averaging 12 miles a day. Almost 

 continuous fog during these days prevented any other scouting 

 so the situation on the eastern edge of the Banks south of 

 latitude 44° N., was largely unknown. Moderate northerly winds 

 on the morning of the 25th brought fine clear weather so the 

 Pontchartrain attempted to scout to the eastward south of the 

 Tail in the cold current in order to determine if any other ice was 

 drifting southward by this route. Fog set in at 1230 so no further 

 scouting could be done this day. The next day and the morning of 

 April 27 was spent maintaining position on the Tail of the Banks 

 awaiting an opportunity to search the eastern and southeastern slopes 

 of the Banks. At 1022 on the morning of the 27th the fog cleared 

 away and the Pontchartrain began a search from latitude 43°35' 

 N., on the eastern edge of the Banks, south and westward around the 

 Tail in order to locate a berg reported on April 25 in latitude 43°16' 

 N., longitude 49°13' W. This berg was found in latitude 42°34' N., 

 longitude 50°45' W., this same day. The search was continued to 

 the westward until dark when the Pontchartrain stopped to drift for the 

 night. 



The next day, April 28, the Pontchartrain continued the scouting 

 westward so as to relocate the berg left on the 25th. This berg was 

 found that same day in latitude 42°06' N., longitude 52°09' W., and 

 the Pontchartrain stopped to drift with this southernmost berg. The 

 next day, driven eastward by strong southwesterly winds and drifting 

 southeastward in the northern edge of the Gulf Stream, the berg 

 showed an amazing drift of 43 miles in 20 hours, averaging over 2 

 miles per hour, and when left on that morning it had been reduced 

 to a large growler and was in latitude 41°50' N., longitude 51°13' W. 

 On leaving this growler the Pontchaiirain steamed northward in order 

 to relocate the berg left 2 days before and to determine the drift of 

 this berg which was found that afternoon in latitude 42°38' N., 

 longitude 51°01' W. The Pontchartrain drifted with this berg the 

 remainder of that day and throughout the night. 



On the morning of April 30, the Pontchartrain scouted southward 

 in an effort to relocate the southernmost ice, the growler which was 

 left the preceding day. This growler was not found, so the Pont- 

 chartrain returned to drift with the berg of that morning and remained
