31.25°; the coldest week was January 16th to 22d, mean temperature 

 25.01°; the coldest day was December 7tb, raeau temperature 3.2°. The 

 mercury fell below zero only ouce, on December 7th, not having previously 

 touched zero since February 19th, 1881. 



The warmest month was June, with mean temperature 74.14°; the warmest 

 week was June 27th to July 3d, mean 82.83°; the warmest day was June 

 28th, mean 84.2°; the warmest hour was 2:80 to 3:30 P. M., September 12th, 

 mean 105°. The mercury exceeded 100° on two days — September 12th and 

 13th — and reached or exceeded 90° on 40 days, viz.: 1 in May, 12 in June, 

 9 in July, 11 in August, and 7 in September. 



The last hoar frost of spring was on May 22d ; the first hoar frost of au- 

 tumn was on October 19th, giving an interval of 150 days, or nearly five 

 months, entirely without frost. 



The last severe frost of spring was on March 24th ; the first severe frost of 

 autumn was on the 11th of November; giving an interval of 232 days, or 

 nearly eight months, without severe frost. This is the longest period of im- 

 munity from severe frost in the past 15 years. No frost during the year 

 caused damage to fruit buds or trees. The hoar frost of May 22d injured 

 strawberries in some localities. 



RAIN. 



The entire rainfall, including melted snow, was 27.60 inches, which is the 

 smallest annual rainfall on our 15 years' record, and is 7.12 inches be- 

 low the average. Either rain or snow, or both, fell on 102 days — one less 

 than the average. On 14 of these days the quantity was too small for meas- 

 urement. 



The longest drouth in the 15 years of observation, was from July 30th to 

 September 18th, during which -period of 7 weeks less than a tenth of an inch 

 of rain was registered. This drouth was not disastrous, because the staple 

 crops were already well matured before the drouth began. 



The number of thunder showers was 26. Hail fell on 7 days. 



SNOW. 



The entire depth of snow was 18 inches, which is 3.31 inches below the 

 average. Of this amount, 2 inches fell in January, 2 in February, 9 in 

 March, and 5 in December. 



Snow fell on 14 days. The last snow of spring was on March 9th ; the 

 first snow of autumn was on November 16th. 



FACE OF THE SKY. 



The average chmdiness of the year was 45.41 per cent., which is 1.08 per 

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

 cloudy) was 162; half- clear (from one to two-thirds cloudy), 103; cloudy 

 (more than two-thirds), 100. There were 80 days on which the cloudiness 

 reached or exceeded 80 per cent. There were 53 entirely clear and 47 en- 

 tirely cloudy days. The clearest month was August, with a mean of 32.37
