CAUSES OF FOREST FIRES ARE CLASSIFIED UNDER THE 
FOLLOWING SIX HEADINGS 
LIGHTNING: Fires the origin of which is directly traceable 
to lightning. 
RAILROADS: Fires incidental to the construction, operation 
or maintenance of common carrier railroads. (This includes fires 
from sparks or cinders from all locomotive or construction engines; 
from lighted cigars, etc., thrown from car windows; from the 
clearing of rights of way, or from the individual carelessness of 
any employee or passenger.) 
LUMBERING: Fires incidental to all lumbering operations. 
(This includes fires caused by sawmills or donkey engines and log- 
ging railroad locomotives, except on such logging railroads as are 
common carriers; and by the carelessness of all lumbering 
employees. 
BRUSH BURNING: Fires caused by clearing lands for any 
purpose (other than for rights of way for common carrier rail- 
roads, and brush burning in lumbering operations,) or by rubbish, 
garbage, range, stubble or meadow burning, and by burning out 
animals, insects or reptiles. 
CAMPERS: Fires resulting in any manner from carelessness 
of campers, stockmen, prospectors, picnickers, surveyors, berry 
pickers, hunters, fishermen, automobilists, tramps and other trav- 
elers through the forest. 
UNKNOWN: All fires the origin of which cannot be deter- 
mined with such degree of certainty as would justify their inclu- 
sion under any other head.
