occupied shortly before coming to Minnesota, where this feature of 

 entomological work is of paramount importance. Mr. O. G. Bab- 

 cock, formerly of the Maryland Experiment Station, is now in 

 charge of our insectary and is a tireless worker. A large part of 

 the success of our exhibit at the State Fair in 1912 is due to his ef- 

 forts. Mr. Warren Williamson is still engaged in research work on 

 the Clover-seed Chalcis and has obtained some striking results. 

 In Mr. George Peake we have a diligent and hard-working assistant. 

 Mr. Ruggles, who has in charge orchard spraying and shade tree 

 pests, is away at date of writing on a seven months' leave of ab- 

 sence, having been called to a postiion on the Chestnut Tree Blight 

 Commission in Pennsylvania. 



The colored drawings in the Report (Plates I, II and III) are 

 faithful representations of specimens taken in Minnesota. The 

 excellent work of the artist. Miss I. L. Wood, has been reproduced 

 by the engravers with remarkable accuracy of detail. 



The custom house officials in St. Paul, Minneapolis and Duluth 

 have been very helpful in their courteous co-operation in connection 

 with the inspection of foreign stock. 



To the Governor of the State and other officials at the State 

 Capitol, the undersigned wishes to express his appreciation of 

 various courtesies. 



Respectfully, 



F. L. Washburn, 

 State Entomologist.
