movements. Reports based upon the information received will 

 be furnished periodically to Forest officers. In order that this 

 information may be accurate and useful, Forest officers will 

 cooperate in every way possible with the men detailed to this 

 work. 



PERMANENT IMPROVEMENTS. 



The constructiojj on the National Forests of suitable head- 

 quarters for the field force, the completion of a good system_of 

 connn unicat ion, the building of fences, corrals, and other 

 works for the control of grazing are of great and immediate 

 importance. Supervisors should study the present and future 

 conditions on their Forests with the greatest care before sub- 

 jnitting plans and estimates, since the improvements when 

 once constructed can not be changed without great trouble and 

 additional expense. 



Each piece of trail, road, telephone line, fence, fire line, and 

 each bridge, cabin, corral, or other improvement should be 

 treated as a separate case and designated by some appropriate 

 name. The Forester will pass upon the recommendations, and 

 if they are approved, authorize their construction and allot a 

 sum of money to cover the necessary expenses. 



If a supervisor finds his estimate or the sum allotted for the 

 work is insufficient to complete it, a full report on the subject 

 should be made to the Forester, and if possible a further sum 

 will be provided. As soon as any project is completed, the 

 supervisor should so report to the Forester, giving the exact 

 cost in detail, including ranger labor. 



All brush and other debris resulting from the construction 

 of roads, trails, bridges, and telephone lines should be handled 

 in the same manner as that resulting from logging. 



The reports and estimates on the various improvements 

 should be prepared in accordance with the instructions which 

 follow.
