Figuee 17. — Soine of the varied duties of forest oíñeers. 



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

 be marked bv rangers. B. When the ever-watchfnl lookout discovers a spiral 

 of smoke. he locates the fire on his map by nieans of the alidade and pro- 

 tractor. The locarion 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 nnder permit on the national forests. In order that the range 

 lands may not become overgrazed. the nurnber of stock allowed each year is 

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

 therefore keep a check on all animáis entering their distriets. D. It is highly 

 important that all parts of the national forests 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.
