RAIN. 



The entire amount of rain, including melted snow, was 44.18 inches, which is greater 

 by 5.67 inches than any previous annual rainfall upon our record, and is 11.20 inches 

 above the average annual amount for the eight preceding years. Either rain or snow 

 fell on 102 days. The unusual amount of rain was well distributed, there being no dam- 

 aging excess or deficiency in any month of the growing season. The longest interval 

 without rain from March 1st to October 1st was nine days. The number of thunder

FACE OF THE SKY. 

 Average cloudiness of the year, 41.27 per cent, of the sky, which is 4.22 per cent. less 

 tlian the average for the eight preceding years. The number of clear days (less than 

 one-third cloudy) was 182; half-clear days (from one-third to two-thirds cloudy), 105; 

 cloudy ( more than two-thirds ), 79. There were 49 days without a cloud, and 31 without 

 a trace of sky. August was the clearest month, with mean cloudiness 26.66 per cent.;

DIRECTION OF THE WIND. . 



During the year, three observations daily, the wind was from the N. W. 330 times; 

 S.W., 313 times; S. E., 147 times; N. E., 135 times; S., 66 times; E., 43 times; N., 32 

 times; W., 22 times; calm, 10 times. The south (including southwest, south and south- 

 east) winds outnumbered the north (including northwest, north and northeast) winds, 

 in the ratio of 526 to 497. 



TELOCITY OF THE WIND. 



The number of miles traveled by the wind during the year was 148,120. This gives 

 a mean daily velocity of 404.70 miles, and a moan hourly velocity of 16.85 miles. The 

 highest hourly velocity was 75 miles, on April 19th; the highest daily velocity was 1,010 

 miles, on February 1st; the highest monthly velocity was 15,690 miles, in March. The
