 discover any other injurious insect causing any damage to crops in this 

 vicinity this year so far.

Dear Sir: The following is my report for insect pests in this local- 

 ity: Chinch Bugs have been very numerous this year, damaging nearly 

 every field to a slight extent, and in some cases the damage has been so 

 great that nearly the whole crop has been destroyed. The acreage of 

 wheat will be lessened in following years on this account. 



Plant Lice, which have been quite a nuisance all summer, are still 

 at work on some flowering plants, viz.: the Snowball and Poppy. 

 Almost no Grasshoppers have been observed. 

 Yours respectfully, 



G. R. MILLS.

 damage done by insects in this section has been received. I will try to 

 do what I can for you. The "Hessian Fly," in particular, has caused a 

 very great loss in this section this year. More than one-third of the 

 wheat has been destroyed by this fly. 



The "Grub Worm" has done sortie damage to the strawberry roots. 

 The "Cut Worm" injured the garden crops to some extent, and the 

 "Potato Bug" was very bad on the potatoes. 



These are the only ones that have bothered us to any extent so far. 

 Very truly yours, 



RUTH H. HOLMBERG.

 territory, but they have been at Ortonville, Clinton, Chokio and on our
