August 1919: "A fire finder has been installed as an aid to the lookout man in properly locating fires. The fire finder consists merely of a map mounted on a piece of metal centered on the point from which observation is made. On the map a protractor graduated into 360 degrees is mounted with zero to the north. The lookout man reads the direction of the fire in degrees and makes references, if possible, to some known point such as approximately a certain distance from a certain mountain, forks of creeks or some other geographic mark. If a reading can be taken from two lookout points it is possible to locate the fire definitely since the intersection of the two readings will always be the point of the fire." (Six Twenty-Six)

Sam is developing a wonderful vocabulary because of the peculiarities of the machine, and has been asked not to express his opinion of it except in places where it would be considered absolutely safe to smoke or build a fire. Some of Sam's remarks would scortch asbestos to a very dark brown." (The Ochoconian)
