valid mining claims may, without permit, fence such portion of their claims as may 

 be needed for pasturing live stock used in the mineral development of such claims. 

 The construction of drift or pasture fences across such claims should not be allowed 

 when objected to by the claimant, except in cases of urgent necessity and then only, 

 after report to and specific instructions from the Forester. 



The owners of patented mining claims are in full possession of the lands and are 

 entitled to every use allowed the 'owners or lessees of any other patented land, but 

 no permit must be issued under the provisions of Regulation 58 allowing stock to be 

 grazed free of charge in exchange for the use of unperfected mining claims. 



Any attempt to use mining claims to control grazing or to get revenue from the 

 lease or sale of grazing rights should be reported to the Forester in accordance with 

 the instructions in this issue under claims. 



Pastures for Milch and Work Animals 



In cases where the circumstances warrant it, inclosures may, under the provisions 

 of Regulation 62, be allowed when needed for the proper handling of stock grazed 

 free of charge, the same as for stock grazed under permit. However, inclosures for 

 stock exempt from grazing fees should not be of greater area than is needed for ten 

 head of milch or work animals. From 40 to 80 acres will be sufficient in most cases, 

 and whenever a larger area than this is allowed, the supervisor should give good 

 reasons for such action in his report upon the rase. 



When an application for an inclosure as above is forwarded to the Forester, the 

 supervisor should always state that the applicant has no grazing permit, but that he 

 is entitled to graze the stock under the provisions of Regulation 42.

OFFICE OF MAINTENANCE. 



Photographs and Photographic Equipment 



Notice should be sent to the Forester of the transfer in the field of all films, note- 

 books, cameras, or other photographic equipment. 



When films are developed in the field, they should be numbered on the border in 

 pencil to correspond with the notebook number. An exact record is kept in the 

 Section of Photography of all films issued from Washington or bought in the field, 

 and it is absolutely essential that these films, without exception, be returned to the 

 Washington office. This applies to blank or defective films, as well as to successful 

 exposures. 



Under the special authorization covering the developing and printing of films in the 

 field in connection with agricultural settlement w r ork, under the act of June 11, 1906, 

 much confusion has resulted from the practice of attaching films to reports on Form 

 110, instead of using prints. When it is not possible to furnish prints w r ith reports, 

 reference will be made to the numbers on the films. 



Each page of an inventory, invoice of, or receipt for property (Form 939) should 

 be signed, as in the case of requisitions for supplies and photographic equipment.
