entrance to Point Amour, passage through the strait was not 

 recommended except for ice-protected vessels. A total of five 

 bergs and growlers was sighted in the strait. The only field ice 

 remaining in the Newfoundland area extended close inshore from 

 Fogo Island to Cape Bauld. Several grounded bergs were sighted 

 in the vicinity of Funk Island and Cape Freels, Newfoundland. 



Due to reduced visibility in widespread fog patches, four flights 

 were necessary between April 20 and 26 to scout visually the area 

 between latitudes 47°00' N., and 50°30' N., west of longitude 

 48°00' W. Except for the grounded bergs sighted on the 19th, no 

 ice was discovered. The same held true for the flight of the 30th 

 north of that area to latitude 52°00' N. 



The Canadian Department of Transport discontinued aerial sur- 

 veys in the Gulf of St. Lawrence on April 30, reporting all routes 

 to river and maritime ports clear for navigation. The extreme 

 eastern limits of scattered ice observed by this semce during the 

 entire season were sighted in early March from Heath Point, Anti- 

 costi to the Magdalen Islands, a marked difference from the 

 normal. 



Ten ice observation flights were made during the month. No 

 bergs were known to have drifted south of latitude 48° 00' N. Dis- 

 tribution of icebergs is shown graphically in figure 5. 



MAY 



After establishing the navigability of the Strait of Belle Isle in 

 early May, a PBIG aircraft was dispatched to Goose Bay, Labra- 

 dor, for aerial ice observations along the Labrador coast as far 

 north as Cape Chidley. On May 6 this plane effected a search 

 60^ miles off the Labrador coast from latitude 55°00' N. to 

 60°00' N. Consolidated pack ice close inshore along with about 

 59 jcebergs were observed from the entrance of Hamilton Inlet to 

 59°00' N. Field ice was light and open north of that point. On 

 the following day, nine bergs were sighted in open water from 

 55°00' N. southward to 51°40' N., west of longitude 51°00' W 

 These bergs were so small that their chances of survival were

 52 57 N., 52°58' W., and was the only ice that was given any 

 chance of completing the long journey to the Banks by entering 

 the eastern branch of the Labrador current. Between the 7th 

 and the 19th this berg was sighted numerous times both by ice 

 patrol aircraft and merchant vessels on track "G". Its final sight- 

 ing on the 19th in position 51°36' N., 53°45' W., indicated a south- 

 southwesterly drift at about 7 miles per day over the 12-day period, 

 i he berg was now so far west and was so reduced in size that it 

 could no longer be considered a possible menace to the major trans-
