7. Fire kills valuable reproduction. 



8. It greatly affects the physical condition of the soil since fire 

 destroys the humus, which is a great factor in keeping the soil 

 loose and flocculated. 



In conclusion it may be said that fire should be used only after 

 careful consideration of both the advantages and the disadvan- 

 tages which its use carries with it. In short it should be used only 

 where the fire danger is great ; where there is no young growth ; 

 where the fire can be controlled ; with fire-resistant species ; and 

 where the injury to the soil is justified by advantages of protec- 

 tion.
