N., longitude 50°10' W. As these were the southernmost bergs for 

 which the Tahoe was searching the Pontchartrain remained with this 

 ice awaiting the arrival of that vessel. With the arrival of the Tahoe 

 a boat was lowered to carry mail to the Tahoe and get the ice observa- 

 tion party. The boat returned, Lt. G. Van A. Graves, ice observer, 

 and the observer's party reported aboard, and at 1528 the Pontchar- 

 train relieved the Tahoe as Ice Patrol vessel. 



During the next 2 days no scouting could be done because of dense 

 fog everywhere over cold water so the Pontchartrain maintained con- 

 tact with the smaller of these two bergs, the southernmost, as it 

 drifted southward. On the evening of June 17 it had moved south to 

 latitude 40°40' N., longitude 49°32' W. The next day, June 18, 

 with good visibility the Pontchartrain searched up the cold current 

 to find the large berg last seen on the 15th and to see if any other 

 bergs had drifted south of latitude 42° N. The large berg was 

 relocated in latitude 41°10' N., longitude 49°29' W., but no other 

 bergs were found. The southernmost berg was not relocated that 

 day due to darkness but was found the next day, June 19, after an 

 intensive search in latitude 40°29' N., longitude 48°47' W. When 

 found it was a very small growler and when left that night had entirely 

 melted in the warm surface water and was stricken from the Ice 

 Patrol records. The next 3 days, June 20, 21, and 22, were spent 

 running the search courses shown on the track chart in, what turned 

 out to be, a futile effort to relocate the large berg last sighted on June 

 18th. The fate of this large berg must remain one of the mysteries of 

 this season. Its huge size on the 18th when last seen would preclude 

 the possibility of its melting during the time it was being searched for 

 but the fact that it has remained unreported since the 18th has removed 

 it definitely as a menace to navigation. 



On the morning of June 23 the Pontchartrain headed to the north- 

 ward up the cold current searching for new ice and particularly to 

 locate a berg reported by the General Greene on the 22nd in latitude 

 42°51' N., longitude 50° 19' W. No new ice was sighted and dense 

 fog which enveloped the cold water just south of the Tail prevented 

 the finding of the General Greene's berg. The Pontchartrain steamed 

 at slow speed up onto the Banks in order to maintain position there 

 until more favorable conditions obtained. No scouting could be done 

 during the next 3 days, June 24, 25, and 26 because of dense fog. 

 On the morning of the 27th, however, reports indicated better visi- 

 bility to southward so the Pontchartrain steamed in that direction 

 clearing the dense fog in about latitude 42°30' N. That day and the 

 next, although continually hampered by fog, the Pontchartrain was 

 able to scout out the southward moving water south of the Tail 

 between latitudes 40°40' N., and 42°30' N. One growler was found 

 in latitude 42°03' N., longtitude 49°40' W., this, is believed to be
