I wish to call especial attention to the results of the work 

 on Paris Green, as given in this report. It is an observed 

 fact that different packages of the' same brand of Paris Green 

 on the Minnesota market, although used in same proportions, 

 give dififerent results, frequently burning foliage to a marked 

 extent. In other words some of the Paris Green is adulter- 

 ated with free arsenic and other compounds, and different 

 amounts of free arsenic being used in dififerent cases, dififer- 

 ent results as to burning foliage naturally follows. It was 

 to expose this practice and to defend farmers of the state from 

 fraud that this department in connection with the chemical 

 department of the station has instituted a series of analyses 

 of samples purchased in dififerent towns of the state. The 

 results are shown in the article on "Poor Paris Green," on 

 page 33. 



Laws regulating the compositions of Paris Green exist in 

 New York, Texas, Louisiana and California. It is evident 

 from what our work brings out that some such law is neces- 

 sary here. 



I am obliged to refer to the extremely crowded quarters 

 afforded the Entomologist at the Experiment Station, a state 

 of afifairs which causes great inconvenience. This unfortunate 

 condition it is promised to relieve two years from now at 

 which time the new state building will be completed and the 

 Entomologist has been assigned an abundance of room 

 therein. A better plan, if it were possible, would be for the 

 university authorities to allow the department a building by 

 itself, which, with the necessary equipment, insectary, etc., 

 could be completed for $18,000 or less. 



The routine work of the department is increasing marvel- 

 ously. As the Entomologist becomes more familiar with the 

 agricultural conditions of the state and enlarges his acquaint- 

 ance among the farmers and fruit growers, new lines of work 

 present themselves so rapidly and so many new and varied 

 relations with the citizens are being continually entered upon, 

 that the ofifice work takes altogether too much time of the 

 Entomologist and he is deprived of the opportunity for much 

 of the research work which would seem to be desirable. The 

 correspondence alone is quite an item, the mail of this office
