wall was observed to be as follows: From latitude 42°00' N., longitude 

 51°00' W., to latitude 40°17' N., longitude 50°09' W., and apparently 

 60° true from the latter position. By the close of the month, however, 

 the cold wall had shifted approximately 45 miles east. A period of 

 low visibility was then experienced and no scouting could be accom- 

 plished. Of the 23 bergs located on the 27tli and 28tli, only 7 were 

 again sighted by the patrol vessel when the fog lifted. It is believed 

 the other bergs drifted out of the Labrador Current into the warm 

 waters of the Atlantic Current and rapidly melted. 



The first reports of ice conditions in the Straits of Belle Isle were 

 received on May 16. At that time conditions were as follows: Heavy 

 close packed ice in all directions as far as could be seen from Belle 

 Isle; heavy close-packed ice everywhere from Point Amour; and 

 •close-packed ice 2 miles offshore from Red Bay. At the close of the 

 month it was indicated that the ice had begun to loosen and move 

 out of the Straits to the southwest. Only two bergs were reported 

 -and these were 5 miles east of Belle Isle. The first berg of the season 

 along the coast of Newfoundland was reported on May 14 and again 

 on the 15th. However, tliis berg is believed to have been very small 

 inasmuch as it was not reported again. Conditions in the Gulf of 

 St. Lawrence improved and the Canadian Ice Patrol was discontinued 

 ior the season on May 3, 1939. During the month of May 365 bergs 

 were known to have entered the area south of latitude 48°00' N. 

 Ice conditions for the month of May are graphically shown on the 

 May Ice Chart. (See fig. 5.) 



JUNE 



A rapid decrease in the amount of ice was experienced throughout 

 the region during tliis month, particularly south of latitude 46°00' N. 

 Only two bergs are known to have drifted south of the Tail, one (1890) 

 sighted by the patrol vessel on June 11 reported on the 23d and on 

 July 1 ; the other (2099) was first sighted on the 18th, reported on the 

 21st and relocated by the patrol vessel on June 24. The drift of 

 this berg to the end of June is graphically shown on the June Ice 

 Chart. (See fig. 6.) It will be noted that the berg moved in exact 

 accordance with the current map constructed at tliis time. (See 

 fig. 23.) However, it is interesting to note that from June 23 to 29 

 the berg was drifting in a cyclonic whirl so that on the latter date it 

 was approximately 16 miles northeast of its position on the 23d. 

 Had southerly winds of fresh or greater force been experienced, this 

 berg probably would have drifted northeast and into the northerly 

 current at a much earlier date. 



At the beginning of the month bergs entered the area from the north 

 generally between longitudes 48°30' W., and 51°30' W., and tended to 

 drift southeastward in the eastern branches of the Labrador Current. 

 As the various eastern bands of the Labrador Current reached their
