50 POLAR PROBLEMS 



It is quite probable that a systematic investigation of radiation at 

 a number of northern stations in Canada would yield results which 

 would throw light on the development of high areas and cold waves, 

 and in addition a few such stations in Greenland especially at high 

 altitudes would be instructive. Meteorological stations reporting by 

 wireless have been placed at several points in Canadian territory with- 

 in the Arctic Circle and have proved most valuable. An extension of 

 these stations is recommended and hoped for. Stations at Coronation 

 Gulf, Chesterfield Inlet, Ponds Inlet, and Churchill are quite likely to 

 be established in the not distant future, and, were Russia to place 

 stations at the New Siberian Islands and at an intermediate point 

 between these islands and Bering Strait, data would be afforded for a 

 much more accurate knowledge of conditions which lead to the devel- 

 opment of Arctic anticyclones.
