Scientific men and the parties they serve are both coming to recog- 

 nize more full}^ the need of studying field conditions and watching the 

 outcome of remedial or control measures. This is one of the encourag- 

 ing signs of the times and means a more practical turn to economic 

 or applied entomology. Federal and state agencies are so well dis- 

 tributed throughout the country, that an important insect outbreak 

 does not remain undiscovered long. Usually several investiga- 

 tors are in the field before serious damage has been caused. In cases 

 of outbreaks by well-known insects, demonstrators of one kind or 

 another are available to show the farmer just how to fight the pests 

 effectively and in case of necessity they may take the lead. The work 

 of the demonstrator is exceedingly important because entomology 

 becomes economic onty in proportion as it is used. The mere posses- 

 sion of adequate knowledge is not sufficient. It must be successfully 

 appfied in saving the crop. Directions, though most lucid, are not 

 always correctly interpreted and the advisor usuallj^ must bear the 

 blame. On the other hand, successful demonstrations cannot be 

 disputed. The method is open to examination and the practical 

 man finds it relatively easy to check up and ascertain the error, if 

 one exists. Demonstrational agencies have greatly increased in 

 recent j^ears. There are some entomologists who give much time 

 to work of this character. Nursery inspectors are available for this 

 purpose to some extent at least. The recent great development of 

 the farm bureau work has resulted in a large increase in men possessing; 

 in most cases, both scientific training and practical experience. The}^ 

 are peculiarly adapted to serve as intermediaries between the investi- 

 gator and the agriculturist. The}^ handle the simpler cases with little 

 or no professional assistance and they are coming, on the other hand,
