 from ships giving positions of no less than sixty sightings. It is recognized

 sion. In return for this Commander, International Ice Patrol offers 

 increased vigilance.

In addition to reports by ships, ice sightings were received by the Ice 

 Patrol from military and commercial aircraft via various air traffic con- 

 trol centers. Acknowledgment is made to the Barrier Forces of the United 

 States Atlantic Fleet, Rear Adm. William E. Martin, Commander, 

 whose patrol aircraft and ships were especially valuable and cooperative. 

 Canadian agencies reporting were Department of Transport aerial ice 

 observers at, Moncton, New Brunswick and Gander, Newfoundland and 

 the Ice Forecasting Central at Halifax, Nova Scotia which furnished 

 daily bulletins for Gulf of St. Lawrence ice conditions. Throughout the 

 field ice season daily reports of ice conditions along the Newfoundland 

 coast were made available to Commander, International Ice Patrol 

 through the courtesy of Canadian National Telegraphs, St. John's. 



Due to the large number of ice reports this year, the usual table of ice 

 reports has been omitted. Instead, a table is presented which gives the 

 name of ships and aircraft reporting ice each day during the season. 

 The number of sightings or reports during the day is given in parenthesis 

 following the name of the ship.
