storm that is of marked energy. In the majority of in- 
stances the duration of the fall is for one or two minutes, 
while the stones are few in number and range from one- 
fourth to one-half inch in diameter though they may be an 
inch or more in diameter. The hail belt is generally a 
narrow strip running from east to west or from the south- 
west to the northeast, but has been reported running in 
other directions. The extent of the belt usually ranges 
from two to four hundred feet in breadth to a half mile or 
more long, skipping a large section to fall again farther 
along. Once or twice during a decade a storm may be 
very severe, covering territory several miles wide and ten 
to fifteen or more miles in length. 
For the fifteen years 1895-1909 the average number of 
hail storms was as follows: March, 2; April, 8; May, 12; 
June, 8; July, 4; August, 4; September, 3; October, 2. 
Many of these were very slight and caused no damage. It 
appears that hail storms are more frequent and severe 
in the northwestern part of the state. Probably the most 
severe hailstorm that has occurred within the history of 
the state was that of September 5, 1898.° 
The following table will give a general idea as to the 
prevalency of such storms and the possibility of injury 
to forest trees:
