Mr Wellman realizes the fact that the winds which he will experience will have 

 much to do in making his expedition a success or failure. He has therefore made 

 a very careful examination of the winds during July and August at Spitzbergen, as 

 recorded by the Fram parties. A number of the wind tables so prepared by him 

 are given in the following pages : 



WIND FREQUENCY IN THE ARCTIC OCEAN 



The following table, condensed from the compilations of Professor Mohn, editor 

 of the meteorological volumes of " Scientific Results of the Norwegian Polar Expe- 

 dition," gives the " averages per mille," or frequency of the winds from the various 

 quadrants of the compass, per thousand observations :
