48°19' W. to latitude 45°09' N., longitude 48°18' W., extending 

 northeast from the latter position. 



During the few hours of good visibility on the morning of the 

 following day nine bergs, three growlers, and field ice were sighted from 

 latitude 44°08' N., longitude 48°34' W. to latitude 44°40' N., longi- 

 tude 48°18' W. On that afternoon the berg sighted on April 6, in 

 latitude 44°55' N., longitude 48°45' W. was relocated in latitude 

 43°56' N., longitude 48°52' W., having drifted south at the rate of 

 30 miles per day. This being the southernmost known ice, the Cham- 

 plain remained in its vicinity during the remainder of the patrol. 

 The General Greene was contacted on April 9 and the current map 

 completed that morning was delivered. On April 10 the Ckamplain 

 set course westward toward the relieving point.

THIRD CRUISE, "CHELAN," APRIL 12-25, 1939 



The Chelan sailed from Halifax, Nova Scotia, at 1113, on April 9, 

 1939, to relieve the Ckamplain on Ice Patrol duty. Moderate to 

 strong northwesterly winds with excellent visibility were experienced 

 enroute to the relieving point. The Champlain was met in latitude 

 43°32' N., longitude 51°49' W. The ice observation party reported 

 aboard and the Chelan relieved the Champlain as Ice Patrol vessel at 

 0012 on April 12, 1939. Course was set for the Tail of the Banks to 

 be in position to commence scouting when visibility would permit. 

 Arrived there on the morning of the 12th and maintained position 

 until the weather cleared on the 14th. ^ 



Search courses were run on the southwestern side of the Tail on the 

 14th, no ice being sighted. At 1450 that day information was re- 

 ceived from Coast Guard Headquarters that the S. S. Bochum, enroute 

 to Montreal, had sustained damages at the water line while working 

 in field ice and was in need of assistance. The patrol vessel set course 

 to intercept her in latitude 48°34' N., longitude 49°47' W. At 1629 

 the Bochum advised that her condition was dangerous and the Chelan 

 increased speed to full. At 0510 the following morning field ice was 

 sighted in latitude 47°12' N., longitude 50°15' W., and course was 

 changed in order to skirt the ice field to the westward. Eleven bergs 

 were sighted from latitude 47°30' N., longitude 50°40' W., to latitude 

 47°41/ N., longitude 51°18' W. At 1054 information was received
