is probably one of the three bergs sighted on May 3. Another small 

 berg was located in 39° water in 45°06' N., 48°49' W. 



At 11:30 a. m. the following day we located the southernmost berg 

 in 44°09' N., 49°08' W. As this berg was in an excellent position to 

 drift southward, the ice-patrol vessel stopped and drifted near this 

 berg to determine its set and drift. At 7 p. m. thick fog set in. This 

 berg was left in 44°01' N., 49°01' W. at 9:55 p. m. and the Pontchar- 

 train ran at slow speed to the southwestward to meet the Mendota. 

 The Mendota was met at 6:10 a. m., May 13, in latitude 42°30' N., 

 longitude 52°45' W., and relief effected. The Pontchartrain then 

 proceeded to Hahfax, Nova Scotia. 



During the patrol 11 bergs were south of latitude 45 N. One of 

 these was first sighted by the Mendota aground in 44°24' N., 49°10'W., 

 on April 24. When last sighted by the Pontchartrain on May 3 it 

 had not moved appreciably or changed its appearance. The drift 

 of tliree bergs was followed from April 30 to May 3, when 4 days of 

 fog covered the ice regions. One of these bergs drifted southward 

 just east of the Grand Banks to latitude 44°00' N., 48°45' W. Here 

 its drift changed to the east and then north. On May 10 a berg was 

 reported in 44°26' N., 47°22' W. Tliis is probably the same berg. 

 The other two bergs sighted on April 30 drifted southward to latitudes 

 44°24' and 44°34', respectively, and curved to the north again. A 

 berg sighted on May 10 in 45°02' N., 47°35' W., is probably one of 

 these two. On May 10 a berg was found in 100 fathoms of water in 

 latitude 44°24' N., 48°57' W. From here it was drifting southward 

 along the 100-fatliom curve at the rate of 15 miles a day, at the end 

 of the cruise, when the patrol vessel headed for the relieving point. 

 The drift of these bergs and current chart completed on April 27 

 indicated that the branch of the Labrador current down the eastern 

 edge of the Grand Banks was very narrow during the last half of 

 April. 



Five bergs were reported on May 11 between latitudes 44° and 

 45° N., and longitudes 46° and 47° W. Here the sea-water tempera- 

 ture of 40° F. indicated that there was a branch of the Labrador 

 current flowing to the southeastward in this area. By May 1 there 

 was a decided decrease in the amount of ice on the Grand Banks 

 west of the 50-fathom curve and by May 5 the Grand Banks were 

 entirely free of ice inside the 50-fathom curve. On April 30 and 

 May 1 numerous bergs were reported north of latitude 48° N., from 

 longitude 48° W., westward to longitude 50°30' W. This ice evi- 

 dently moved southeastward, and bergs became numerous north of 

 latitude 46° N. as far east as Flemish Cap. The easternmost ice 

 reported was a berg in 48°52' N., 41°56' W. 



During the cruise the weather continued mild. The first few 

 days of the cruise north and northeast winds predominated. Then
