over the northern counties on the night of the 17-18th. This storm was 

 also attendrd by heavy rain and high winds and did considerable dam- 

 age to corn within the area covercfl. Jvight and widely scattered showers 

 occurred between the 4th and !)th, the 13th and on the 19th and 20th, 

 but dry weather and intense sunshine prevailed during the last decade 

 of the month. 



Except in some of the northern counties, all vegetation suffered by 

 the absence of moisture and the long continued high temperatures. At 

 the close of the month, pastures were brown, late potatoes were practi- 

 cally a failure, and corn was daily deteriorating. Wells were failing 

 and small streams were dry in the southern part of the state, and in 

 many localities stock was being fed as in winter. Fruits also suffered. 

 Apples and grapes are small and apples are dropping from the trees. 

 The ground was too dry and hard to permit much if any fall plowing to 

 be done, and if conditions do not improve soon the acreage of fall sown 

 grains will be greatly reduced.
