LETTER OF TRANSMITTAL 



Bozeman, Montana, January ], 1921. 



To His Excellency, 



Governor Joseph M. Dixon, 

 Helena. Alont. 

 My dear Sir : 



In conformity with the law I ha\e the honor to present here- 

 with the Eig-hteenth 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.
