changed within three days to excessively warm and continued so during 

 the remainder of the month. The deficiency of temperature during the 

 first half of the month, however, nearly equalled the excess during the 

 latter half as the monthly mean was only 0.7° above the normal. At 

 many stations the record for the number of days with a maximum tem- 

 perature of 90°. or higher, was broken: there being from 9 to 11 days 

 with temperature up to or above 90°, and the average of the maximum 

 temperatures for the last 15 days of the month was above 90°. 



The past month was the driest June on record since statewide obser- 

 vations began in 1890. The average rainfall was only 1.99 inches which is 

 2.53 inches below the normal, and .68' inch less than the average for 

 June, 1894, which was the driest June on record prior to the past month. 

 Showers were frequent during the first 10 days, over the western and 

 central sections of the state but after the 10th the rainfall was light and 

 unevenly distributed; the western counties receiving the larger amounts. 

 In the eastern part of the state the rainfall was light during the entire 

 month. 



Corn made very slow growth during the first half of the month and 

 owing to poor seed, cold weather and the activity of the moles and 

 cut and wire worms, much more replanting was done than usual. During 

 the latter half of the month, however, corn made very rapid growth 

 and was nearly up to the normal stage of growth at the end of the* 

 month. The dry weather and intense sunshine were exceptionally fa- 

 vorable for killing weeds and the fields were never cleaner at the end 

 of June than they were this year. The soil was in the very best of 

 condition to withstand the effect of dry weather. Small grains made 

 considerable advancement and at the close of the month were in good 

 condition and filling and ripening nicely. On the whole June was a 

 favorable month, though the condition of all crops at its close was 

 somewhat below the average of the past 10 years; hay, pasturage and 

 early potatoes receiving the greatest damage from the drouthy conditions.
