JULY. 



The most notable characteristics of the month were the high tempera- 

 tures that prevailed during the first five days; the unusually cool weather 

 from the 11th to the 28th; the excessive amount of sunshine; and, over 

 the larger part of the state, the continuance of the severe drought that has 

 obtained for the past three months. From the 1st to the 5th inclusive, 

 the temperature was excessively high, the maxima being 100° or above on 

 one or more days at all but one station in the State. At many stations in 

 the southwestern counties the temperature was above 100° every day from 

 the 1st to the 5th, a record that has not been equalled since July, 1901. The 

 highest temperature reported during that time was 111° at Bloomfield on 

 the 3rd and at Jefferson and Keosauqua on the 5th. From the 6th to the 

 11th, inclusive, the weather was somewhat cooler, and between the 11th 

 and 28th it was unusually cool for July, the 17th being the coolest day gen- 

 erally, although the lowest temperatures in the northeastern counties oc- 

 curred between the 24th and 25th, when all previous records were broken 

 for low temperatures during the last 15 days of July. 



The severe drought that has obtained during the past 3 months contin- 

 ued over the larger part of the State during the entire month. In the 

 eastern counties the drought was broken by copious showers on the 6th 

 which were followed by fairly well distributed showers during the re- 

 mainder of the month, with heavy rains on the 28th. Over the western 

 two-thirds of the State, the drought continued with increased severity not- 

 withstanding the fact that there was only one day, the 1st, during the 

 month on which rain did not fall at some place in the State. The amounts 

 of rainfall over the western counties were, however, too small, and the in- 

 terval between showers at any one place too great to be of much benefit 

 to crops. At the close of the month corn had suffered material injury, not 

 only by the drought, but by the excessively high temperature during the
