the General Greene's berg. On June 29 the search was continued to 

 the northward but was stopped early m the day by the low blanket of 

 fog which enveloped the cold water just south of the Tail and covered 

 completely that important area from the southern tip of the Banks 

 south to about latitude 42°20' N. Because no further scouting could 

 be done, and the growler, upon relocation that night, was found to 

 to be so small as to no longer constitute a danger, the Pontchartrain 

 headed west for the relieving point. 



The Tahoe was met m latitude 43°05' N., longitude o3°44' W. A 

 boat was lowered and Lt. G. Van A. Graves, ice observer, and the 

 observer's party were transferred to the Tahoe and at 1450 June 30 

 the Tahoe relieved the Pontchartrain as Ice Patrol vessel. Course 

 was set for Halifax, Nova Scotia, arriving there at 0710, July 2, 

 1938.

TENTH CRUISE, "TAHOE," JUNE 30 TO JULY 14, 1938 



The Tahoe sailed from Halifax, Nova Scotia, at 2004, June 28, 

 1938. Gentle to moderate breezes from the northeast shifting to 

 southwest with fog or rain were experienced during the voyage east- 

 ward until the morning of June 30 when the wind shifted to south 

 and increased to a fresh breeze for 5 hours. The Pontchartrain was 

 met in latitude 43°04' N., longitude 53°26' W. Lt. G. Van. A. 

 Graves, ice observation officer, and the observer's party reported on 

 board and at 1430, June 30, 1938, the Tahoe relieved the Pontchartrain 

 as Ice Patrol vessel. 



The Tahoe cruised to the vicinity of the Tail of the Grand Banks 

 during the evening and night of that day and at daybreak started a 

 search of the cold water south of the Tail to latitude 41°50' N., no 

 ice being sighted. At 1912, July 1, the Tahoe arrived in latitude 

 42°59' N., longitude 49°40' W., where fog formed over the cold 

 water so that no further scouting could be accomplished that day. 

 Visibility the following day being 4 to 5 miles the Patrol vessel scouted 

 up the cold current to latitude 44°41' N., longitude 48°48' W., where 

 a large berg was found. As no ice was found in the vicinity of track 

 C it was recommended to headquarters that the use of this track be 

 authorized. Fog set in at 2215 and the Tahoe, being unable to locate 

 the berg the next morning, headed northward to contact the General
