are our old frioiids, the Icccn-oyed forest raiigers and park rangers. Of 

 course, if they discover any alarming insect oufbreal^ at any time, they re- 

 port it promptly. Bat the discovery is not left merely to chance. Once 

 a yecx each ranger i:nalces a complete, systematic survej'' of his district, 

 keeping on a sharp lookout for d^ang trees. He examines any he discovers 

 for pigns of insect danage, reports the conditions, and may send in one 

 or more of the insects he suspects is the culprit. If a num.ber of trees 

 are infested he travels hack and forth through the forest counting the 

 dcjnagcd trees to determine the approximate area end extent of the dcjr^e. 



Reports are forwarded from district forest or park headquarters to 

 the nearest branch headquarters of the Bureau of Entomology. In the West, 

 there is a district entomologist at Portland, Oregon, one at Berkley, 

 California, and one at Coeur d'Alene, Idaho. If a report looks at all 

 alarming, the entomologist maj'- rush to the scene to inspect the trouble 

 himself. The forest and park service officials are advised of the danger, 

 and those officials determine whether the manaced timber or scenic value 

 v;arrants the expense of fighting the insec-: in that ps-'.Lcular arca« 



Of course, forest and park rajigers are not alvT;.ys insect experts, 

 Some are naturally more observant than others. But at the annual ranger 

 schools, the entomologist trains these men in the method of mald.ng sur- 

 veys, takes them into the forest and shows them the insect at work, and 

 otherwise prepares them as insect scouts,
