was known to contain large masses of heavy field ice and many bergs 

 was now found to be almost entirely free of ice with exception of three 

 small bergs and five growlers in scattered positions sighted on April 4, 

 Tliis ice had apparently been blown off the coast and down from the 

 north by the prevailing northerly winds. With the completion of this 

 search on the evening of April 4 the Champlain headed to the south- 

 westward toward the relieving point. 



The Mendota was met in latitude 43°31' N., longitude 56°15' 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 1700 

 April 5, 1937, the Mendota relieved the Champlain as ice observation 

 vessel. The Champlain set course for Halifax, Nova Scotia, arriving 

 there, without incident, at 1545, April 6, 1937.

FIFTH CRUISE, "MENDOTA," APRIL 5 TO 20, 1937 



The Mendota sailed from Halifax, Nova Scotia, at 0600, April 4, 

 1937, to relieve the Champlain as ice observation vessel. The voyage 

 to the relieving point was accomplished without incident. Fresh to 

 strong north and northeast winds with the accompanying rough sea, 

 prevailed. The Champlain was met at 1530 and Lt. G. Van A. Graves, 

 ice observation officer, and the observer's party reported aboard and 

 the Mendota relieved the Champlain as ice observation vessel at 1700, 

 April 5, 1937, in latitude 43°39' N., longitude 56°23' W. The Mendota 

 set course to the eastward crossing the Banks and arriving on the 

 eastern edge at daylight, April 7. That day and the next 2 days, 

 April 8 and 9, the Mendota scouted out the cold current between i 

 latitude 44° N., and 45° N. On April 7 three bergs and two growlers ■■ 

 were sighted in this area. One berg was large and had grounded in i 

 33 fathoms of water in latitude 44°25' N., longitude 49°05' W. On ; 

 April 8, the grounded berg was relocated and had not moved, butt 

 poor visibility prevented a thorough search for the other ice. How- 

 ever, two growlers were found that day and on April 9, all the icei 

 seen on the 7th was relocated showing a southward drift of about 16< 

 miles per day. The General Greene was sighted this day and while she 

 was on station in latitude 44°20' N., longitude 48°48' W., one seamaD 

 from the Champlain was transferred to the General Greene to fill a 

 vacancy in her crew. April 10 was foggy and no scouting could be^ 

 done.
