44 NATIONAL FOREST MANUAL GRAZING. 



No Reduction Because of Partial Use. 



No reduction in grazing fees will be made when the stock do not 

 graze upon the National Forest during the entire period allowed, nor 

 will an increased number of stock be allowed to enter the Forest for 

 this reason. (See "On-and-off permits," p. 38.) 



Additional Time Allowance. 



The supervisor may allow stock to enter not more than 15 days in 

 advance of the date fixed for the beginning of a grazing period, or 

 allow it to remain 15 days after the expiration without additional 

 charge, when the needs of the people demand such action and the 

 condition of the range warrants. The additional time will not be 

 stated in the permit, but permission to enter before or remain after 

 the regularly established dates will be given either by general notice 

 or by a letter written to the applicant.- 

 Extension of Permits. 



If suitable range is available within the National Forest, grazing 

 permits for short periods may be canceled and amended permits 

 issued foi any of the longer periods established for the Forest upon 

 payment of the difference between the rates established for the two 

 periods. The fee representing the difference between the two rates 

 must be paid not only upon stock covered by the original permit, 

 which are to be grazed during the extended period, but also upon all 

 additional animals which have i cached the age of 6 months during 

 the original permit period. 



Supplemental Extension Permits. 



In the extension of permits for the summer season to cover a 

 longer period, supplemental permits for the number of stock which 

 have reached the age of 6 months, in excess of the number covered 

 by the permit for the summer season, may be issued whenever this 

 Will not result in injury to the Forest. 



Any increase in the number of stock allowed under such an exten- 

 sion is temporary, and the applicant's preference for the following 

 year will be based on his original permit. 



Minimum Division of Rate. 



In determining the rates for periods less than one year, no division 

 of less than one-fourth of 1 cent will be made in the rates for sheep, 



foats, or swine, or of less than 1 cent in the rates for cattle and horses, 

 'or example, if in computing the rate for a short period on sheep the 

 result obtained is 6.87 the rate will be fixed at 6f cents, but if the 

 result is 6.88 the rate will be fixed at 7 cents. Under the same plan, 

 if the result obtained in computing the rate for a short period on 

 cattle is 28.5, the rate will be fixed at 28 cents, but if the result is 

 28.6 the rate will be fixed at 29 cents. 



Charge for Irregular Periods. 



In cases where it is difficult beforehand to determine the use that 

 can be made of a privilege, fees should be charged and permits issued 

 for the established period which most closely meets the requirements 

 of the case. Special authority may be secured later for refund of 

 the unearned portion of the fee when the circumstances warrant on 

 the basis of the percentage of use secured by the permittee. Since a 

 refund requires the approval of the district forester, permits must 

 not be issued with the understanding that a refund will be made.
