lO INJURIOUS INSECTS OF I90Q AND I9QIO. 
GRASSHOPPERS. 
During the summer of 1910 grasshoppers have worked more 
havoc than for years before. Numerous complaints were received 
in 1909, but it would seem that these complaints merely indicated 
that the “hoppers” were gathering their armies, as it were, and pre- 
paring to work all the havoc they could in 1910. The accompany- 
ing map indicates by crosses the counties from which complaints 
regarding grasshoppers were received during the above-mentioned 
two years, and also the number of localities in each county from 
which we received inquiries; by far the largest number representing 
complaints sent in during the season just passed. These crosses 
represent by no means the entire number of inquiries or reports of 
injury, since in almost every case many complaints came from one 
town. The circles shown mark localities suffering in I910 from 
the attacks of the Wheat-head Army Worm.
