LETTER OF TRANSMITTAL. 
STATE EXPERIMENT STATION. 
UNIVERSITY OF MINNESOTA. 
December 31, 1902. 
To His Excellency, S. R: Van Sant :— 
In accordance with the law I have the honor to present here- 
with my first Annual Report (Seventh of the Series) as entomol- 
ogist of the Experiment Station of the University of Minnesota, 
for the year ending December 31, 1902. My official connection 
with the Experiment Station began June Ist of the current year, 
but the work was taken up a month earlier, immediately upon my 
arrival in Minnesota. Since May ist I have answered by mail 
- many inquiries relative to insect pests besides numerous questions 
presented in person. I have sent out numerous circulars relative 
to Hessian Fly, Chinch bugs and Grasshoppers and have written 
several press articles along these and other lines. 
Press Bulletin No. 12, entitled “A Remedy for the Mosquito 
Evil,’ was issued in May. Trips have been made into various 
parts of the state at the request of farmers and citizens who call 
upon me for advice and demonstrations in connection with differ- 
ent insects. The farmers have assured me that these trips upon 
the part of the entomologist have been helpful and they have been 
a very evident means of the latter becoming acquainted with the 
people, with the farming conditions and with the native insect 
fauna. 
In the following pages I have endeavored as far as possible 
to use original illustrations though I have not hesitated, where it 
seemed necessary in order to make clearer the appearance and life 
history of any pest, to introduce figures from previous reports and 
from other sources. I have further endeavored to avoid technical 
language and to present information in the simplest manner pos- 
sible.
