The prevalence of the N. and N. W. winds is here strongly marked, especially in 

 winter. At two of the stations more than half of all the winds come from the N. W. 

 The exception presented by Port Bowen, where E. winds largely prevail in winter, 

 is explained by the large land-mass to the E. The winds of the inland and western 

 stations of Arctic America, as well as the Arctic Ocean in their vicinity, show more 

 irregularities.

From the foregoing table it appears that in Northern British America (Forts 

 Norman, Simpson, Enterprise, Reliance, Franklin, and Anderson) there is no ac- 

 cordance in the direction of the winds. They seem to vary much according to 

 locality. This is a very cold region, and being continental, calms are much more 

 prevalent in winter than in the Archipelago. We must expect to find here higher 

 pressure in winter than further to the east, because the depression about Iceland is 

 not so near. 



The great distance of the Atlantic depression and tlie mountains which lie 

 between this region and the Pacific depression, also explain the undecided charac- 

 ter of the winds in winter. 



We have fewer observations in the summer. Among these, Fort Franklin has 

 prevailing E. winds, coming from Great Bear Lake, where the ice does not melt 

 till the end of the summer. 



In Alaska monsoon winds are seen to prevail from the N. E. (the land) in winter,
