the Mendota on the 27th were the only two bergs east of the 50-fathom 

 curve, known to be south of 46°00' N. 



After arriving in the vicinity of the Grand Banks the weather was 

 generall}^ mild and foggy. During the first part of the cruise light 

 east winds predominated. Then the winds were southerly for the 

 rest of the cruise with exception of the 24th and 27th. North winds 

 on the 24th and westerly winds on the 27th brought relief from the 

 fog on those 2 da,ys. The percentage of time with fog after arriv- 

 ing in the ice-patrol area was 76.0. 



The following is a summary of the ice and water temperature re- 

 ports received during the cruise: 



Number of bergs reported south of 48°00' N 161 



Number of bergs reported south of 43°00' N 



N imiber of ice reports received 269 



N umber of water temperature reports received 1, 046 



Number of vessels furnishing ice reports 42 



Number of vessels furnishing water temperature reports 146 



Number of vessels furnished special ice information 9

SECOND CRUISE, "PONTCHARTRAIN", APRIL 29-MAY 1.3, 1934 



The Ponichartrain sailed from Boston at 8:28 a. m., 26 April, 1934, 

 to relieve the Mendota on International Ice Patrol. The Mendota 

 was met in 42°30' N., 52°45' W., at 8 a. m., April 29, 1934. The ice 

 observation party reported aboard, and the Pontchartrain relieved the 

 Mendota as ice-patrol vessel. We then headed for a position 15 miles 

 south of the tail of the Grand Banks to begin a search for ice. On the 

 following day with excellent visibility we searched to the northward 

 in the Labrador current just east of the Grand Banks between the 

 100- and 1,000-fathom curves as far north as latitude 45°00' N. A 

 berg was located in 44°18' N., 48°50' W., in 775 fathoms of water. 

 This berg was about 200 feet long, 100 feet wide, and 45 feet high. An 

 old water line gave evidence that it had recently turned over 90°, 

 making its former top a side. From this berg we headed for a berg 

 aground in 33 fathoms of water in latitude 44°24' N., longitude 49°08' 

 W. Tliis proved to be the same berg sighted near this position on 

 April 24 by the Mendota. Its position or appearance had not ap- 

 preciably changed since it was last sighted. Before dark bergs were 

 sighted in latitude 44°37' N., longitude 48°53' W., and 44°44' N., 

 48°51' W. At 7:55 p. m. the ice-patrol vessel stopped and drifted 

 for the night. 



On May 1 we scouted to the southward to latitude 43°30' N., on 

 parallel courses 25 miles to the east of those steered on the previous 

 day. No ice was sighted in tliis area. Then the bergs sighted the
