A mimeographed circular giving the names of the National Forests, with their 

 origin, definition, or derivation, has been sent to Forest officers. It contains data 

 which has been collected from time to time during the past three years. The For- 

 ester will be glad to receive additions or corrections. 



SILVICULTURE 



Silvics: Library 



As a record of all the books and periodicals purchased by members of the Forest 

 Service is kept in the Service library, the librarian should be notified at once when- 

 ever such purchases are to be made. When a large number of books is to be pur. 

 chased at one time, from funds other than those set aside for books for field libraries, 

 the amount necessary for their purchase should be transferred to the field library 

 fund, and the books ordered through the Service library. No books will be paid for 

 from this fund unless ordered through the library, with the approval of the library 

 committee. 



GRAZING 



Crossing Permits, Regulation 66 



Crossing permits should not be issued in cases where it is clearly apparent that 

 the stock, by reason of its weak physical condition, can not be driven across the 

 Forest without great delay and trespass upon ranges allotted to permittees. 



While the crossing of live stock over National Forests should be facilitated to the 

 fullest extent compatible with the proper protection of the Forests, crossing 

 privileges should not be granted in cases where hardship or irreparable damage to 

 permittees will result, or where it is evident that a trespass will follow. A violation 

 of the terms of a crossing permit is a trespass and should be reported as such. 



Although the refusal of a crossing permit may be warranted by the circumstances, 

 the Forest officer handling the case should take every reasonable precaution to pre- 

 vent suffering or loss of stock and should not expose the Service to criticism by arbi- 

 trary or ill-advised action.
