 on the afternoon of June 26, 1928. 



The isotherm chart for the short seventh cruise was based on but 

 366 temperature observations sent in by 29 cooperating vessels. 

 Only one ice report was received from south of the forty-eighth 

 parallel. This was for a small berg reported in 46° 15' N., 48° 17' W. 

 on June 21. 



Vessels apparently commenced using the Belle Isle tracks on June 

 21, for 23 bergs and several growlers were reported to the patrol on 

 that date from between Greenly Island and 52° 30' N., 53° 00' W. 



Special information on request was sent to three vessels. No dere- 

 licts were heard of, and but one spar and one buoy were reported 

 from within the patrol area. No oceanographic stations were taken. 



Upon the discontinuance of patrol messages of thanks for efficient 

 assistance were sent to the radio stations at Cape Race, Halifax, and 

 St. Pierre. The final ice broadcasts were sent out on the evening of 

 the 22d and on the morning of the 23d. They contained thanks to all 

 cooperating ships for their indispensable assistance in the form of 

 ice, water temperature, weather, and other reports. 



Before leaving the patrol area, the following gratifying message was 

 received from W. F. Berg, master of the Vacoil, "Realizing the hard- 

 ships endured by the patrol, I wish to express my appreciation for 

 your most valuable assistance to us during the past season. " Before 

 reaching Boston similar messages of appreciation were received from 

 the Majestic and Olympic.
