In this Table II. (1), are given the number of days in each 

 month in which the prevailing Winds came from each of the 

 four principal points of the compass. The first column (1), 

 including the winds from the N. and N. E. ; the second (2), those 

 from the E. and S. E. ; the third (3), the S. and S.W. winds; and 

 the fourth (4), the W. and N. N. W. winds. At the bottom of the 

 columns is shown the greatest, least, and mean number, and 

 the last right hand column the total number of days for the 

 year. Of the direction of the wind for the year they blew 

 seventy days from the N. N. E. ; seventy-six from the E. S. E. ; 

 one hundred and five from the S. S. W., and one hundred and 

 fourteen from the W. N. N.W., or one hundred and forty-six 

 days from an easterly direction, and two hundred and nineteen 

 days from a westerly direction.

Table II (2) gives the winds for the seasons, the average 

 number of days in which they blew from the four quarters of 

 the horizon, with the month furnishing the number from the 

 same direction nearest corresponding thereto. 



In the Spring, the winds of April correspond with nearly to 

 those of each of the quarters of the horizon; for the Summer, 

 June; for the Autumn, October, and for the Winter, those of 

 December. 



The same results are herewith plainly exhibited in Diagrams 

 C and D, of Table II (3), the former showing the relative 

 frequency for the year; the latter for the Summer, (June, 

 July and August) in the full curve; and for Winter, (Decem- 

 ber, January and February, of the same year, in the dotted 

 curve.
