SNOW. 



The entire depth of snow was only six inches, all of which fell in February. This 

 is 15.96 inches below the average, and with the exception of the five inches in 1875, 

 is the smallest annual snow precipitation on our record. Snow fell on 11 days, on 

 9 of which the quantity was too small for measurement. The last snow flurry of 

 spring was on April 5th; the first snow flurry of autumn was on November 25th — 

 17 days later than the average date. 



FACE OF THE SKT. 



The mean cloudiness of the year was 43.82 per cent., which is .3 per cent, below 

 the average. The number of clear days (less than one-third cloudy) was 167; half 

 clear (from one to two-thirds cloudy), 103; cloudy (more than two-thirds), 95. There 

 were 87 days on which the cloudiness reached or exceeded 80 per cent. There were 

 60 entirely clear and 51 entirely cloudy days. The clearest month was August, with 

 a mean of 33.36 per cent.; the cloudiest month was February, mean 51.78 per cent. 

 The percentage of cloudiness at 7 a. m. was 47.69; at 2 p. m., 49.56; at 9 p. m., 34.21. 



DIEECTION OF THE WIND. 



During the year, three observations daily, the wind was from the N.W. 290 times, 

 S.W. 213 times, S.E. 198 times, N.E. 168 times, S. 113 times, N. 46 times, E. 43 times, 

 W. 24 times. The south winds (including southwest, south and southeast) outnum- 

 bered the north (including northwest, north and northeast) in the ratio of 524 to 504. 



VELOCITY OF THE WIND. 



The number of miles traveled by the wind during the year was 120,230, which is 15,222 

 miles below the average for the preceding 16 years. This gives a mean daily velocity 

 of 329.4 miles, and a mean hourly velocity of 13.73 miles. The highest velocity was 

 84 miles an hour, on August 12th, from 5:43 to 5:58 p. m. ; the highest daily velocity 

 was 1,030 miles, on the 29th of December; the highest monthly velocity was 13,380 

 miles, in May. The windiest months were May and December; the calmest months 

 were June and July. The average velocity at 7 a. m. was 12.75 miles; at 2 p. m., 13.39 

 miles; at 9 P. m., 13.77 miles. 



BAKOMETEB. 



Mean height of barometer column, 29.125 inches, which is .018 inch above the 

 annual average. Mean at 7 a.m., 29.145 inches; at 2 p.m., 29.107 inches; at 9 p.m., 

 29.121 inches. Maximum, 29.948 inches, February 23d; minimum, 28.415 inches, 

 January 16th; yearly range, 1.533 inches. The highest monthly mean was 29.244 

 inches, in February; the lowest was 29.020 inches, in May. The barometer observa- 

 tions are corrected for temperature and instrumental error only. 



EELATIVE HUMIDITY. 



The average atmospheric humidity for the year was 73.2; at 7 a.m., 82.1; at 2 p.m., 

 59.5; at 9 p. m., 78. The dampest month was September, with mean humidity 78.6; 

 the driest month was April, mean humidity 61. There were 28 fogs during the year, 

 which number has been but once equaled — in 1884. The lowest humidity for any 

 single observation was 6 per cent., on November 6th. 



The following tables give the mean temperature, the extremes of temperature, 

 the number of inches of rain and snow, the number of rainy days, the number of 

 thunder showers, the mean cloudiness, the relative humidity, the number of fogs, the 

 velocity of the wind, and the mean and extreme barometer heights for each month 

 of the year 1889, and a comparison with each of the 21 preceding years:
