The average temperature of July and August was lower 

 than usual. The cool weather during those two months 

 retarded the ripening of corn, and was evidently injurious to 

 most crops, judging from the unusual prevalence of fungous 

 diseases. 



The first frost occurred September 23 ; the first snow-fall 

 occurred November 27, and the first snow-storm, December 

 5, amounting, in the latter ease, to an inch and a half of 

 snow. The severest snow-storm, amounting to 6.5 inches 

 of snow, occurred December 14. Both of these snows 

 disappeared soon. 



During eight months of the year the prevailing wind was 

 north-west ; during March, September and October, the 

 prevailing direction was north-east; and during June, 

 south-west. 



The rainfall during the year amounted to 43.72 inches, 

 which is slightly below the average. The number of days 

 on which an appreciable quantity of water fell was 128. 

 The largest number occurring in one month was 15, in July ; 

 the smallest, 7, in August. The largest rainfall for one 

 month was 8.35 inches, in July; the smallest, 1.45 inches, 

 in February. 



During the first seven months of the year there were fifty- 

 four days during w^hich the sky was more than seven-tenths 

 overcast by clouds at each observation. During the last five 

 months, when a more detailed system of taking the observa- 

 tion was used, sixty-six days were noticed "cloudy;" 

 twenty cloudy days occurred in September. On twenty- 

 three days during the first seven months, the sky was found 

 less than four-tenths overcast at each observation. April 

 and June had each but one "clear" day; during the last 

 five months there were but twenty-four clear days. 



The mean annual temperature was 47.78 degrees, which 

 is nearly 1 degree above the average. The highest tempera- 

 ture for the year was 89 5 degrees, occurring May 9 ; the 

 lowest, — 9 degrees, occurring February 24. The maximum 

 for 1888 was 94.5 degrees, on July 23 ; the minimum, — 21.5 

 degrees, January 23. The absolute range of temperature 

 for 1889 Avas 98.5 degrees, against 116 for 1888, 115.2 for 

 1887, and 117 for 1886.
