fall; an excess of sunshine and the small number of damaging wind, 

 hail and electrical storms. Unseasonably cool weather prevailed from 

 the 7th to the 12th, inclusive. The previous low temperature record was 

 equalled at many stations, and at some the temperature was lower than 

 ever before recorded in June. Frost occurred on low ground in many 

 localities on two or three nights, but no serious damage was done, al- 

 though the upper leaves of corn were frozen and in some places tender 

 garden truck was cut down. After the 12th the temperature was almost 

 continuously above the normal; the highest readings being recorded from 

 the 14th to the 20th, and from the 26th to the close of the month, when 

 the maximum readings were generally above 90", and up to 100° at sev- 

 eral stations on the 29th. 



The average rainfall was 3.31 inches or 1.21 inches less than the nor- 

 mal. Except from Pocahontas County westward to Woodbury and Plym- 

 outh Counties, there was generally sufficient moisture to keep vegetation 

 growing rapidly, but over the area mentioned the rainfall was very light, 

 with long intervals between showers. From the 20th to the 25th, in- 

 clusive, showers were frequent and the ranifall heavy over the southern 

 and east central districts. The showers on the night of the 24th were, 

 in many localities, accompanied by wind squalls, which lodged and tangled 

 small grain badly. 



As a whole, however, the month was exceptionally favorable for the 

 agriculturist. Corn probably never made more rapid growth between 

 the last planting and the end of June than it did this year. Many 

 fields w^ere knee to waist high and much of the crop has been laid by 

 in the southern counties by the close of the month. Fall sown grains 

 were ripe and the harvest had begun, in the southern part of the state, 

 with every indication of good yields. Much clover and alfalfa hay had 

 been put up in fine condition. Pasturage continued good^ and the gen- 

 eral crop conditions were excellent.
