rate as green timber of the same species unless it is 

 clearly shown that the products manufactured from 

 it command a lower market price or that logging 

 costs are higher. 



Cutting Period. Ordinarily the cutting period 

 allowed in each sale is only sufficient to permit the 

 removal of the timber at a reasonable rate, approxi- 

 mately equivalent to the working capacity of the 

 plant. Sales of accessible timber usually do not 

 exceed 5 years in length. However, in the case of 

 inaccessible tracts requiring a large investment for 

 transportation facilities an exception is made and 

 periods of from 15 to 20 years may be granted. 



Readjustment of Stumpage Rates. In all sales 

 exceeding 5 years in length provision is made to 

 have the stumpage rates readjusted by the For- 

 ester at the end of three or five year intervals to 

 meet changing market and manufacturing condi- 

 tions. 



Refunds. Deposits to cover or secure advance 

 cutting or to accompany bids apply on the first pay- 

 ment if a sale is awarded to the depositor; other- 

 wise they will be refunded. Refunds are also made 

 to the purchaser if the last payment is in excess of 

 the value of the timber that is cut.
