"The winter of 1891-92 had almost exactly the same mean temperature as the winter 

 preceding, but had a minimum temperature a few degrees lower. Though it was 

 slightly less cloudy, it had a snowfall nearly twice as great, and the snow covered 

 the ground for a longer time, especially during March, although the early winter 

 was open and trying to wheat. Frost occurred on May 8, somewhat injuring the 

 cherries. 



" During the growing season the temperature was a trifle higher than in 1891, but the 

 cloudiness, rainy days, rainfall, and relative humidity were considerab ly higher. The 

 amount of sunshine was very nearly the same. Snow fell to the depth of 5^ in. on 

 April 13, retarding oats sowing, a cold wave prevailing at that time. In latter May 

 cold weather prevailed; heavy rains in the middle of June lodged grass and grain 

 badly, while hail injured the corn of the neighborhood. July was an excellent 

 growing month. Potatoes and corn were harvested in good condition."
