between s. and w. s. w. The number of days that each blew in all the months 

 being collected into one sum at bottom, shows the number of days each wind 

 blew in the whole year. The quantity of rain that fell in each month is added, 

 that the connection between wet and dry, and the several winds may the more 

 readily appear. It appears that the winds from the s. w. prevailed more than 

 any other in the year 1774; and next to the s. w. the n. e. But the s. w. was 

 more frequent than the n. e. in the proportion of 126 to 74. Of the winds 

 from the 4 cardinal points, the n. was the most frequent, and the e. the most 

 rare. In the 3 summer months, June, July, and August, there fell more rain 

 than in the 3 of any other season. Of the 26.312 inches of rain which fell in 

 the whole year, 13.826 fell in the winter half year, consisting of the 6 months 

 of September, October, November, December, January, and February, and 

 12.486 in the summer half year, consisting of the 6 months of March, April, 

 May, June, July, and August. So that the winter's rain exceeded the summer's 

 by 1.3-10 inches; that is, by little more than -rV part of half the rain of the 

 whole year. September gave the greatest quantity of rain, and April the least 

 of any single month in the whole year.

In these 2 tables the winds between the w. and the s. w. are all set down to 

 the w. s. w.; and those between the s. and the s. w. are all reckoned s. s. w. In 

 like manner, the winds between the e. and n. e. are all reckoned e. n. e.; and 

 those between the n. and n. e. are all reckoned n. n. e. It appears that of the 

 winds between the s. and w. those from the point of s. w. were far more fre- 

 quent than those from either side of it. And the winds from the point of n. e. 

 more frequent than those on either side of it, nearly in the same proportion.
