THE USE BOOK. 85 



Only inexce^tignal cases will a iperiod of more than 

 three years for the removal of timber be allowed. 



A sale should be closed when the time allowed for cutting and 

 removal has expired or when the purchaser has fulfilled all 

 conditions of the contract. When a sale is ready for closing, 

 the supervisor should stamp the final cutting report, " This sale 

 is closed." No other notice of closure will be sent to Washing- 

 ton. All timber trespass, sawmill, timber settlement, and For- 

 ester's free-use cases will be closed by letter. 



Extensions of time should be granted only when some un- 

 avoidable circumstance has delayed the purchaser's operations. 

 When an extension of time is not granted, any timber which 

 may have been cut but not removed will revert to the Forest 

 Service. Extensions must never be given verbally, and in ease* 

 where a bond has been given, the consent of the sureties must 

 be obtained. 



When Ihe postponement of brush piling is necessary, blank 

 copies of the application and bond to be used will be furnished 

 to the supervisor upon request by letter. The amount of the 

 bund, if one is required, should be at least twice the estimated 

 cost of brush piling. Before postponement of brush piling 

 under a contract which contains no provisions for delay and 

 on which bond was required, it will first be necessary to have 

 the consent of the sureties.
