During the afternoon of the 1st, from about 5:45 till 6:10 p. m. a 

 tornado occurred in the southern portion of Adams County. The storm 

 moved first from the northwest to southeast then turned and moved to the 

 northeast, the total path being about 20 miles. The width of the storm 

 was narrow and at points the funnel did not reach the earth, but where it 

 was in contact with the earth everything in its way was destroyed, the loss 

 to crops and buildings amounted to about $100,000. There was no loss of 

 lives but 4 persons were injured and the occupants of one residence had a 

 remarkable escape from being burned to death in a wrecked house that 

 caught fire and burned up. 



Hail storms were unusually numerous, destructive and widely distrib- 

 uted over the State. The worst storm reported was in the northwest por- 

 tion of Scott county on the 9th, and the damage there was estimated at 

 about $100,000. The principal damage was in a strip about 12 miles long, 

 varying from about one and three-fourths to about 9 miles wide, extending 

 from 3 miles southeast of New Liberty to about 3 miles south of Mays- 

 ville. The path of greatest damage was about 6 miles long and about 

 one and one-half miles wide. The stones varied from about 0.2 inch to 0.7 

 inch in diameter but some were said to be 1.5 inches. The damage from 

 hail in other portions of the State was large. The storms reported shows 

 losses to crops approximating $1,000,000, but it is probable that the loss 

 was considerably more than that amount.
