Forest Fires 



Great fires in virgin forests usually 

 occur in dead INSECT KILLED TIM- 

 BER during dry seasons. Accumulated 

 ground litter and everpresent standing 

 dead, injured and pitchy trees furnish 

 ample fuel to lead the flames into green 

 timber. This necessary fuel largely results 

 from the continuous and intermittent 

 attack of DESTRUCTIVE FOREST 

 INSECTS upon the roots, base, trunks, 

 limbs, branches, twigs and buds of trees 

 throughout their entire life. Forest fires 

 in green timber increase the INSECT 

 RISK by concentrating insect attack 

 and reducing the number of beneficial 

 insects. Avoid your constant annual 

 loss. Reduce your fire risk. Control 

 the insects responsible. It is good busi- 

 ness. Efficient inspection of Parks, 

 Watersheds, Estates and Timberlands. 

 Control methods outlined. Control costs 

 estimated. Control work conducted 

 economically.
