on the second ice observation cruise. From a point off Cape Race, 

 a temperature section was run to 50°00' N., 47°00' W., with bath- 

 thermograph casts every 5 miles. Search was then made for a berg 

 in the vicinity of 49° N., 51° W., which would be of suitable size for 

 making measurements of its set and drift. A medium-sized berg was 

 located at 49°28' N., 51°23' W., at 0710 G. c. t. on 2 June and the 

 Mendota stood by it, observing its set to be between north and 

 north-northeast and its drift 0.4 knots, until 0000 G. c. t. on 3 June, 

 when departure was taken for 40°50' N., 46°42' W., where a berg 

 had been reported by the S. S. Esso Glasgoiv. From the evening of 

 4 June, when the Mendota arrived near the position in which the 

 berg had been reported, until the evening of 8 June, an area about 

 100 miles wide and 150 miles long extending in a general north- 

 easterly direction from the reported position was searched by the 

 Mendota with her surface search supplemented by air search on the 

 6th and 8th. As the berg was not sighted and was unreported by 

 any of numerous ships passing through the area on track B during 

 good visibility, it was concluded that the berg either had disinte- 

 grated in the warm water and heavy seas or had drifted to a posi- 

 tion of relatively minor hazard and still higher temperatures south- 

 eastward of heavy traffic lanes. Accordingly the Mendota was 

 recalled to Argentia, where she arrived on 11 June. 



After replenishing supplies, she departed the same day to con- 

 tinue the cruise. A berg was located at 49°40' N., 49°47' W., on the 

 evening of 12 June. The ship remained in the vicinity of this berg 

 for 24 hours during which the berg's set and drift were determined 

 to be south-southeast to southeast at 0.4 knots. The following 2 days 

 were spent searching for a suitable berg on which to take drift 

 measurements farther offshore to the northeast. No bergs were 

 found in this area, so a course was laid for the eastern end of the 

 Strait of Belle Isle. Here, on 15 June, a series of bathythermograph 

 casts were made at 5-mile intervals, crossing the strait from the 

 vicinity of Cape Bauld to the Labrador side. Another temperature 

 section with similarly spaced measurements was then run across 

 the Labrador Current from Belle Isle to 53°59' N., 49°34' W. On 

 completion of this section, a course was laid for South Wolf Island, 

 which was reached on 17 June. From here another temperature 

 section was run with the bathythermograph to 55°32' N., 52°00' W. 

 The 18th and 19th were spent in cruising on the Labrador shelf 

 eastward of Hamilton Inlet sighting and resighting several bergs. 

 Sightings at 54°47' N., 53°58' W., and 54°28' N., 53°41' W., and 

 54°16' N., 53°28' W., and 54°04' N., 53°04' W., were believed to have 

 been of the same berg, in which case its set and drift would have 

 been south-southeast to southeast at 1.4 knots. As continuous con- 

 tact was not maintained for any extended period of hours, however, 

 these several sightings may or may not have been of the same berg.
