No. 6. DEPARTMENT OF AGRICULTURE. 219 



(3) We need an insectary, like a small greenhouse room, for main- 

 taining outdoor conditions for the breeding eggs, containing insects 

 of which the life histories should be studied and observed carefully 

 in normal conditions. 



(4) We need at least a small tract of a few acres conveniently 

 situated where experiments can be performed, testing spraying ap- 

 paratus and materials, and other features of warfare against pests, 

 in order to let us keep always to the front with the latest and best 

 practical information for our citizens. It is not proper that we 

 should be obliged to depend only upon the study of what comes to 

 us in the form of literature from our Experiment Station and from 

 other states. With facilities for some experimental work much 

 valuable information could be gained concerning new materials, ap- 

 paratus, methods of tests, etc., and reports can be given on those 

 which are worthy of recommendation and general adoption in practi- 

 cal use. 



Respectfully submitted, 



H. A. SURFACE, 

 Economic Zoologist of Pennsylvania.
