ing, although even within recent years the losses from fire 

 in some states have exceeded the entire season's cutting. 

 During 191 6 very considerable damage was caused by fires

 per acre is now comparatively small because steps are at once 

 taken to dispose of the remaining timber before it has begun 

 to decay. During the same year two very serious forest fires

 tain kinds are almost gone. This condition of affairs is
