The following diagram shows the variation in the relative frequency of the 

 winds dm-ing summer (June, July, August), and winter (December, January, 

 February). ^

The proportional number for each wind indicates the predominance of the N. W. 

 and the S. W. winds on the average during the year, of the S. W. wind in summer 

 and of the N. W. in winter. The least frequent winds are from the S. and E. ; 

 from the E. in summer, and from the S. in winter. The numbers in the general 

 table also indicate that the transition in the direction of the whid is gradual 

 during the annual fluctu.ation. 



The characteristic fluctuation for the two seasons is the decrease of the S. W. 

 wind to less than one-half its amount from summer to winter, and the increase of
