LETTER OF TRANSMITTAL 



Bozeman, Montana, January 1, 1921. 



To His Excellency, 



Governor Joseph M. Dixon, 

 Helena. Mont. 



My dear Sir : 



In conformity with the law I have the honor to present here- 

 with the Eighteenth Annual Report of the State Entomologist of 

 Montana, which will appear as Bulletin No. 139 of the Montana 

 Experiment Station. 



The outstanding features of the year were an extensive and 

 serious outbreak of grasshoppers affecting many counties through- 

 out the state, in which Mr. Strand from this office cooperated exten- 

 sively with the farmers through the county agents and effected 

 large savings in crops ; and the widespread presence of the pale 

 western cutworm which year by year is becoming a more serious 

 situation. Both of these subjects are discussed in the report and 

 your attention is directed particularly to these matters. 



Very respectfully, 



R. A. COOLEY, 



State Entomologist.
