NINETEENTH ANNUAL MEETING. 143 



titles, fell on 103 days — one less than the average. On 15 other days, rain or snow 

 fell in quantity too small for measurement. 



The number of thunder showers was 28. There was but one light hail storm dur- 

 ng the year. 



The drouth which prevailed during July, August and September was the only seri- 

 ous drouth in Kansas since 1874. From June 26th to July 24th, an interval of 27 

 days, there was an entire absence of rain. From the same date to September 16th, 

 a period of 81 days, the rainfall was but 2.85 inches. In 1874 the drouth extended 

 from June 14th to September 3d, an interval of 80 days, during which the rainfall 

 was only 2.19 inches. Thus the drouth of "86 was one day longer than that of "74, 

 but the latter began nearly two weeks earlier in the season, and was therefore more 

 disastrous in its efifects. 



SNOW. 



The entire depth of snow was 23.50 inches, which is 1.96 inches above the average. 

 Of this amount twelve inches fell in January, one inch in February, four inches in 

 March, four inches in April, half an inch in November, and two inches in December. 

 Snow fell on 31 days. The last snow of spring was on March 27th. The first snow 

 of autumn was on November 11th — three days later than the average date. 



FACE OF THE SKY. 



The mean cloudiness of the year was 39.64 per cent., which is 4.99 per cent, below 

 the average. The number of clear days (less than one-third cloudy) was 189; half 

 clear (from one to two-thirds cloudy), 91; cloudy (more than two-thirds), 85. There 

 were 59 days on which the cloudiness reached or exceeded 80 per cent. There were 

 64 entirely clear and 39 entirely cloudy days. The clearest month was October, with 

 a mean of 25.91 per cent.; the cloudiest month was January, mean 61.93 per cent.

 highest velocity was 70 miles an hour, on March 21st; the highest daily velocity — the 

 second highest on our record — was 1,120 miles, on the 8th of January; the highest 

 monthly velocity was 13,900 miles, in March. The windiest months were January, 

 March, April and November; the calmest months were May, June, July and August.
