Figure 17. — Some of the varied duties of forest officers. 



, Before national-forest timber is advertised for sale, the trees to be cut must 

 be marked by rangers. B, When the ever-watchful lookout discovers a spiral 

 of smoke, he locates the fire on his map by means of the alidade and pro- 

 tractor. The location of the blaze is then phoned to the nearest fire station, 

 and fire fighters are sent to the scene of action. C, Grazing of sheep and 

 cattle is allowed under permit on the national forests. In order that the range 

 lands may not become overgrazed, the number of stock allowed each year is 

 limited to what the range will carry without permanent injury. The rangers 

 therefore keep a check on all animals entering their districts. Z), It is highly 

 important that all parts of the national forest where fire danger exists be 

 accessible to fire fighters, and each year the Forest Service is adding to its 

 mileage of roads and trails. Forest officers oversee and frequently take part 

 in road-construction work.
