The Table shows 



a) that there is a prevaihng uniformity in the distribution of the winds 

 in the same month in the different years; 



b) that North is by far the most prevalent wind in all months of all 

 years, with the exception of June, in which month — except in 

 1901 — South is a little more frequent than North; 



c) that the other wind-directions are relatively rare. 



The maximum and minimum of the relative frequency of the diffe- 

 rent wind-directions are as follows:

The Calms are the most frequent, being nearly one third of the 

 total number of cases. 



Of the winds. North is the most frequent; and next to it comes 

 South. The least frequent wind is West, and then East. 



Taking the positive difference between the numbers in the Table 

 on pp. 222 & 223 for the opposite wind-directions, e. g. N— S, NE— SW, 

 etc., and tabulating them, we obtain the following Table, showing 



The Windward Side of the Wind-Rose.
