RECORD AND RESULTS OP 



If we double the numbers in each column, we find the number of hours during 

 which each wind blew, or during which it was calm, for each period. The pre- 

 vailing wind is the N. E., next to it the S. W., whUe the relative frequency of the 

 calms is between the two ; all other winds are about equally unfrequent. Expressed 

 in percentage the frequency of the N. E. is 47, of calms 27, of S. W. 17, and for 

 the six remaininj? directions on the averap-e 11.

This table exhibits the extreme variations in the frequency of the winds at dif- 

 ferent localities and in different years ; at Van Rensselaer Harbor, with a northwest 

 exposure, the N. E. wind is least frequent ; at Port Foulke, with a west exposure, 

 it is the most frequent wind. At the latter place the number of hours of calms is 

 half that noted at the former place. 



Average Velocity of the Wind. 



The average velocity of each of the eight principal winds for each season and 

 year is found by dividing the sum of the velocity numbers by n, or the number of 

 entries during the period; the velocity is expressed in miles per hour.

Average velocity of all winds throughout the year 19 miles per hour, producing 

 a moderately fresh breeze. The average velocity of th 3 air, taking also the number 

 of calms into consideration, is 14 miles per hour. At Van Rensselaer Harbor the 

 average velocity of all winds was 7, in Baffin Bay 17, and at Port Kennedy 18 

 miles per hour. These numbers are not strictly comparable, since the velocity of 

 the wind at each locality depends upon estimation. 



The velocities of the N. E. and S. W. winds alone are tolerably well ascertained, 

 there being too few entries of other winds.
