TENTH ANNUAL YEAR BOOK— PART I 11 



8.00 inches to over 13.00 inches. It uas also heavy over the Missouri divide 

 and the extreme northwestern county. Showers occurred at some station 

 in the State on every day of the month except the 19th. And yet there 

 were on an average, 12 clear days. Thunder and lightning accompanied 

 most of the showers hut wind squalls and severe hail storms were not as 

 frequent as usual. The frequent and excessive rains caused high water in 

 all rivers and creeks, especially in the western districts. The flat and bot- 

 tom lands were flooded two or three times and a large acreage of corn 

 v/as finally abandoned after being replanted once or twice. The surplus 

 moisture also interfered with the cultivation of corn on ground not 

 thoroughly drained and many fields are quite foul. With all the adverse 

 conditions corn on uplands and well drained fields, and these comprise 

 nearly 90 per cent of the total acreage, has made very satisfactory prog- 

 ress considering its late start and much of it is up to the standard for 

 this season of the year and the fields were generally clean. Where the 

 fields have not received proper cultivation the corn is short and uneven 

 and it depends on future weather as to whether or not it matures. The 

 condition of small grain, grass, potatoes and garden truck has improved 

 during the month, but there has been a decline in the condition of fruit.
