150 THE USE BOOK. 



Rangers execute the work < of the forest reserves 

 under the direction of the supervisor. Their duties 

 include patrol to prevent fire and trespass, estimating, 

 surveying and marking timber, the supervision of 

 cuttings, and other similar work. They issue minor 

 permits, build cabins and trails, enforce grazing restric- 

 tions, investigate claims, report on applications, and 

 arrest for violation of reserve laws and regulations. 



Forest rangers may act as assistants to the super- 

 visors. They have authority over deputy and assist- 

 ant rangers and forest guards. They may be given 

 charge of the field work of any portion of a reserve to 

 which the supervisor is unable to give adequate per- 

 sonal supervision or of the whole reserve during 

 periods when press of office work prevents the super- 

 visor from taking the field. 



When the absence of the supervisor requires some 

 one in charge of his office, this duty falls on the forest 

 ranger; although if there are more than one, or if there 

 is a forest assistant attached to the reserve, the super- 

 visor may detail whichever of these he thinks best, 

 unless otherwise instructed by the Forester. No ranger 

 is authorized to hire assistance himself except in cases 

 of fire. 



Deput}^ rangers and assistant rangers have charge of 

 definite districts, to which they are assigned by the 

 supervisor. They supervise forest guards stationed 

 within their districts, and may also be given temporary 

 laborers when necessary. 



It is the policy to fill vacancies by promotion when 

 competent men can be found, rather than by appoint- 

 ment of men without forest reserve experience, al- 

 though otherwise well fitted.
