A RESULT OF REPEATED FIRES THROUGH PAST CENTURIES 
The highest grades of lumber are obtained from the first, or butt log. This is the point of 
attack of every fire scar, which, as it is enlarged, not only burns its way into the heartwood 
but permits the entrance of fungi, a very destructive agent. Fire protection can not save 
this big fellow, but its results are clearly seen in the amount of reproduction already estab- 
lished near by
