44°11' N., 48°27' W. From these bergs we continued the search to 

 latitude 45°00' N., 47°50' W. Then we ran 25 miles on course 270° 

 and scouted down the eastern slope of the Grand Banks to latitude 

 44°10' N. Bergs were located in 44 °32' N.,48°26' W.,and44°22' N., 

 48°33' W. The 4 bergs sighted on June 2, and 3 on June 1, account 

 for all 7 of the bergs sighted on May 29. All these bergs were small 

 and in the last stages of disintegration. The wind instead of the 

 current had controlled their drifts since first sighting them. 



On June 3 the patrol vessel scouted from latitude 45° up the eastern 

 slope of the Grand Banks to latitude 46°40' N., and then ran 25 miles 

 on course 90°. Then we ran to the southward reaching latitude 45° 

 at dark. Only four bergs were sighted in tliis area. During the 

 night the Pontchartrain ran at slow speed on course 170°. At day- 

 light June 4 the course was changed to 263° true and the speed in- 

 creased to 15 knots. A berg was sighted in 44°26' N., 48°02' W. 

 Throughout the day we ran parallel easterly and westerly courses 

 from the eastern slope of the Grand Banks to longitude 47°50' W., 

 between latitudes 44°15' N., and 43°20' N. At 5 p. m. we ran to the 

 southwest, parallel to the Grand Banks from latitude 43°20' N., for 

 45 miles. During the day growlers were sighted in 43°27' N., 48°20' 

 W., and 43°52' N., 48°17' W. These growlers and the berg sighted the 

 same morning were all that remained of the seven bergs sighted on 

 May 29. 



On June 5 the ice patrol vessel ran up the eastern slope of the Grand 

 Banks from latitude 43°20' N., to latitude 44°00' N., and then ran 

 east to longitude 48°. In longitude 48°00' N., the search was changed 

 to the north for 25 miles and then changed to the westward. A berg 

 was found in 44°24' N., 48°29' W., sea-water temperature 40°. 

 This berg is probably the same as one reported in 45°03' N., 48°40' W. 

 on June 3. Just east of the Grand Banks we ran north for 25 miles. 

 At 5:07 p. m. the wind increased to a moderate southwesterly gale 

 accompanied by rain. The vessel was headed into the wind at slow 

 speed. The gale moderated at midnight. By this time dense fog had 

 set in. The ice-patrol vessel proceeded to 44°12' N., 49°30' W., and 

 anchored. The fog cleared at 9 a. m. At 8 p. m. the Pontchartrain 

 proceeded at 15.5 knots to the eastward to locate a berg reported in 

 43°47' N., 45°04' W., 48 miles northwest of the westbound track B. 

 This berg was found in 43°58' N., 44°32' W., at 10:20 a. m. on June 

 7. It had drifted 27 miles 65° true from the reported position in 

 approximately 24 hours. The ice-patrol vessel stopped and drifted 

 near this berg. It was approximately 350 feet long and 100 feet high. 

 It was in an unbalanced state of equilibrium and rocked slowly back 

 and forth for 40°. Later in the afternoon it turned completely over. 

 Fifteen miles west of the berg the sea-water temperature was 42° F. 

 It increased rapidly on approaching the berg. Five miles away it
