two with an experienced man before trying more cases 
alone, rather than to displace him. He should not ordi¬ 
narily be given charge of other cases until he has had 
such coaching. 
LINES OF WORK. 
FIRES. 
Law enforcement is concerned with man-caused fires. 
Until fires of unknown origin can be proved otherwise, 
they must, with respect to enforcement investigation, be 
viewed as man-caused. At all such fires the ranger has 
two duties—(1) to see that the fire is put out, and (2) to see 
that every possible measure is taken to detect the person 
responsible. 
Investigation must be started immediately, before clues 
in the vicinity of the fire are obliterated. However, this 
does not mean that suppression of the fire can be neglected. 
Careful planning and scheduling of both lines of work will 
be necessary, first by the supervisor as a forest policy, then 
by the ranger in charge of each district. Because investi¬ 
gation is new and not well understood by the field men, its 
direction must be given careful attention by all adminis¬ 
trative officers, and fire plans must be so arranged as to per¬ 
mit of pushing both investigation and suppression simul¬ 
taneously. Short-term men must be assigned with 
reference to the requirements of investigation and their 
capacity for the work, and should be instructed as provided 
on page 25 of this manual. 
FISH AND GAME. 
The new regulation T-7 marks the entrance into our 
national forest policy of a more vigorous attitude toward 
fish and game. These are now to be recognized as a 
national asset, which should be conserved on the national 
forests just as timber or forage is conserved. The Forest 
Service policy regards as legitimate such use of a resource 
as is consistent with maintenance of supply, but as illegiti¬ 
mate any use in excess of that requirement. This raises 
enforcement of the fish and game laws and cooperation
