FACE OF THE SKY. 



The average cloudiness of the year was 40.65 per cent., which is 4.52 per 

 cent, below the average. The number of clear days (less than one-third 

 cloudy) was 190; half-clear days (from one-third to two-thirds cloudy), 93; 

 cloudy (more than two-thirds), 82. There were 59 entirely clear, and 37 

 entirely cloudy days. The clearest month was August, with an average

DIRECTION OF WIND. 



During the year, three observations daily, the wind was from the N. W. 

 327 times; S. W., 281 times; S. E., 134 times; N. E., 136 times; E., 60 

 times; S., 55 times; N., 53 times; W., 28 times; calm, 21 times. The north 

 wind (including northwest, north and northeast) outnumbered the south 

 winds (including southwest, south and southeast), in the ratio of 516 to 470. 



VELOCITY OF THE WIND. 



The number of miles traveled by the wind during the year was 125,793, 

 which is 16,078 miles less than the average annual distance for the past six 

 years. This gives a mean daily velocity of 344.47 miles, and an average
