V. That the scarring of trees is not confined to those 

 of the small diameter classes is shown by the following 

 table prepared by T . T. Hunger.

This would prove that the more valuable species, 

 yellow pine, is much less fire resistant than douglas 

 fir. frhe percentage of fire-scarred yellow pine trees 

 increa-ses progressively as the trees become larger. In 

 other words, the number of fire-scarred trees is in di- 

 rect proportion to the number of surface fires the jiel- 



—1 

 low pine has to withstand.!
