area in latitude 44°59' N., longitude 48°27' W. The PontcJiartrain 

 drifted with this berg during the night but failed to locate the 

 berg the following day, May 30, because of dense fog. On May 31, 

 with excellent visibility, the Pontchartram searched the area for this 

 berg and located it in latitude 45°06' N., longitude 48°02' W. This 

 was unmistakably the same berg sighted on May 29, and it had 

 drifted northeasterly at 10 miles per day. A small growler was 

 found in latitude 44°56' N., longitude 47°49' W. The Pontchartrain 

 continued to search to the southward and at 2007 stopped to drift 

 for the night. The next day, June 1, the Pontchartrain commenced 

 scouting to the northward over the area not covered the previous day 

 in order to make sure no other ice was drifting southward along 

 the edge of the Banks south of latitude 45° N. At 0800, this 

 doubtful area was covered, completing the scouting of the area 

 between latitudes 44° N., and 45° N., along the eastern slope of the 

 Grand Banks and a line 45 miles east thereof. No ice except the 

 small growler sighted May 31 was found in this area. At 0825 

 dense fog set in and the Pontchartram stopped and drifted. At 1144, 

 the Pontchartrain proceeded at various speeds depending on the 

 visibility, toward the estimated position of the southernmost berg. 

 This berg was located at 1600 in latitude 45°10' N., longitude 48°07' 

 W., and the Pontchartrain stopped to drift with the berg for the 

 night. 



The next day, June 2, being cloudy and rainy, no scouting could 

 be done nor could a new position be obtained for the berg, so at 1415 

 the Pontchartrain headed for the relieving point. The Mendota was 

 met at 2240, June 3, in latitude 43°20' N., longitude 54°46' W. A boat 

 was lowered and Lt. G. Van A. Graves, ice observation officer and 

 the observer's party were transferred to the Mendota^ and at 2310 

 June 3, the Mendota relieved the Pontchartrain as Ice Patrol vessel. 

 The Pot^tchartrain set course for Halifax, Nova Scotia, arriving 

 there at 1914, June 5, 1935. (See fig. 15.)

SEVENTH CRUISE, "MENDOTA", JUNE 4 TO JUNE 18, 1935
