the berg sighted on April 24 was visited. It was found to have 

 moved about 6 miles to the northward into 55 fathoms of water. 

 Its size was greatly reduced, both from melting and from the sea. 



During the same day the Pontchartrain located seven other bergs. 

 Five of them were between the 50 and 100 fathom curves and between 

 latitudes 46° 07' N. and 46° 23' N. The other two were just outside 

 the 100-fathom curve in latitude 46° 06' N. Then the Pontchartrain 

 was headed for the position of two bergs that were reported near 

 latitude 45° 10' N., longitude 48° 45' W., as these were the southern- 

 most known ice. These bergs were found the following morning in 

 latitude 45° 04' N., longitude 48° 00' W., and latitude 44° 52' N., 

 longitude 48° 52' W. Then the Pontchartrain scouted to the eastward 

 for 45 miles and to the southward for 30 miles. On May 1 the drift 

 of the bergs sighted the day before was determined. The northern- 

 most berg had drifted southward at the rate of Iji miles per hour, 

 while the other drifted 150° true at 1% miles per hour. The Pontchar- 

 train drifted near the southernmost berg during the night of May 1. 

 The next morning it was found that the berg had drifted east at two- 

 third miles per hour. The other berg was in sight, having followed 

 practically the same route as the first berg. 



On May 1, the Pontchartrain and the General Greene made contact. 

 The commander, international ice patrol, the senior physical ocean- 

 ographer, the ice observation officer, and the officer in charge of the 

 General Greene held a conference. Also, a box of thermometers was 

 delivered to the General Greene. The night of May 2 was spent 

 steaming toward a rendezvous with the Tampa in 43° 00' N., 52° 30' 

 W., where contact was made at noon May 3, 1932. The ice obser- 

 vation party was transferred to the Tampa and relief effected. The 

 Pontchartrain then proceeded to Halifax. 



At the beginning of the cruise the southernmost ice was in latitude 

 45° 30' N., and between longitudes 48° and 49° W., where 22 bergs 

 had been reported on April 17. Nearly a week of fine, clear weather 

 over the entire ice regions enabled the ice limits to be definitely 

 located. Two bergs reported in 45° 00' N., 48° 45' W., on April 13 

 could not be found in the cold water south of their reported position. 

 It is presumed that they drifted north again. The area east of the 

 Grand Banks south of latitude 45° N., was thoroughly scouted and 

 no ice was found there until April 30, when the Pontchartrain sighted 

 a berg in 44° 52' N., 48° 52' W. 



Icebergs and growlers were very numerous along the Canadian 

 track "£;' between longitudes 48° W. and 49° 15' W. On April 19 and 

 20 no less than 74 different bergs were reported in this region. After 

 this date a good many ships bound to and from Canada detoured the 

 berg-infested waters and crossed longitude 48° W. in latitude 45° 

 30' N. By April 27 bergs were beginning to be less numerous inside
