was set for the Tail of the Banks in order to be in position to search 

 for ice when weather conditions would permit, arriving in position at 

 1018 on March 29 and drifting in fog throughout that day. During 

 a period of good visibility from March 30 to April 2, the Labrador 

 Current was scouted out from latitude 42°35' N., longitude 50°00' 

 W around the Tail and north to latitude 45°30' N. Only one berg 

 was sighted, this in latitude 45°07' N., longitude 48°23' W. on April 2. 

 On April 1, 1939, daily radiometeorograph observations were com- 

 menced 'in accordance with Headquarter's letter February 25, 1939. 

 The only handicap experienced was the carrying away of the radio- 

 meteorograph antenna due to vibration on April 2. This casualty 

 had also occurred while enroute to the Ice Patrol area. The antenna 

 rod was replaced by a quarter-inch cable, 44.5 inches long. The 

 insulator and cable antenna were supported by a wooden staff with 

 a top over-hang constructed of bakelite so that the antenna was 

 suspended vertically and held 6 inches from the wood support. The 

 balloon ascent on the morning of April 3 proved this replacement to 

 be a success. The meteorograph was foUowed for about 17,000 

 meters at which point the balloon burst and the meteorograph was 

 followed part way down. 



Foggy conditions existed over the cold water during the 3d and 

 4th so' the Chamjdain scouted in the mixed warmer water to the 

 eastward of the Labrador Current on these dates. On April 3 a 

 bero- was sighted in latitude 45°16' N., longitude 47°26' W., and a 

 second berg in latitude 44°57' N., longitude 47°18' W. The latter 

 berg was relocated the following morning in latitude 45°07' N., 

 longitude 47°07' W., and that day a third berg was sighted in latitude 

 45°03' N lono-itude 48°07' W. With excellent visibihty on April 5 

 the cold current was scouted out from latitude 43°30' N. to latitude 

 45° 15' N. and the only ice found in this sector was a growler m latitude 

 45°01' N., longitude 48°39' W. 



The patrol vessel drifted in dense fog during most of April 6; how- 

 ever, there was sufficient visibihty during the last 3 hours of daylight 

 to permit scouting of the Labrador Current from latitude 44°55' N. 

 to latitude 45°26' N. The following ice was sighted: Berg, latitude 

 44°55' N., longitude 48°45' W.; berg, latitude 45°13' N., longitude 

 48°34' W; and field ice from latitude 44°52' N., longitude 48°40' W. 

 to latitude 45°26' N., longitude 48°35' W., extending northeastward 

 from the latter position. At 1732 on April 6 the S. S. Marine Trader 

 was sighted working southward along the western edge of the field 

 ice and that vessel requested position of the soutliernmost field ice 

 The desired information was furnished by means of International 

 Code flag hoists. On April 7 the Champlain searched the cold water 

 from latitude 44°10' N. to latitude 46°00' N., sighting 15 bergs and 

 5 growlers Field ice was observed from latitude 45°03' N., longitude
