A GRAPHIC STORY OF BROADCAST BURNING IN THE WESTERN WHITE 
PINE TYPE 
(A) shows the condition shortly after the broadcast burn; all standing timber has been killed, 
and the ground is covered with a heavy growth of fireweed, grass, and thistle which in 
August will become very inflammable. (B) is the same area a few years later; dead trees 
are beginning to fall, and the inflammability is, if possible, greater than that of the original 
slash, as is also the difficulty of fire control. (C) reveals the common outcome of the condi- 
tion shown in (B); the area has been burned over several times until with complete destruc- 
tion of the forest there is no hope of obtaining natural reproduction of forest trees; and 
withal, inflammability is greater than in green timber
