NATIONAL FOREST MANUAL GRAZING. 79 



Cattle and horses will use approximately 2 pounds of salt per head 

 per month from the time the green feed begins until midsummer 

 and 1 pound per head per month during the remainder of the year. 

 This quantity is in excess of that fed on most ranges, but experience 

 has demonstrated that a liberal use of salt is a profitable investment. 

 A lack of salt causes cattle to collect around old salt grounds and 

 tramp out considerable range. 



QUARANTINE AND LOCAL LAWS. (Reg. 



Enforcement of Quarantine Regulations. 



Whenever the stock in any locality is known to be infected with a 

 contagious disease, or notice to that effect has been given the For- 

 ester or district forester by the Bureau of Animal Industry, the 

 owners of all stock to be grazed in National Forests must, if required 

 to do so, subject the stock to inspection, and, if found necessary, have 

 such stock dipped or otherwise treated before it is allowed to enter. 

 At any time during the period for which a grazing permit has been 

 issued, if the stock is found to be infected with a contagious disease, 

 it must be dipped or otherwise treated in accordance with the instruc- 

 tions of the inspectors of the Bureau of Animal Industry, or the per- 

 mit will be canceled and the stock removed from the National Forests. 



Upon receipt from the Forester of a statement of quarantine or

 dering them the necessary assistance and furnishing them with a list 

 of the permittees, the dates upon which the stock wifl enter the Forest, 

 and aU other information required. 



The same routine will be followed in regard to State quarantine 

 regulations, unless they conflict with the regulations of the Bureau 

 of Animal Industry.

 be undertaken by the Forest Service except in cooperation with the 

 Bureau of Animal Industry or State official in charge, and supervisors

 guidance. 



Upon receipt of requests for the enforcement of State or Federal 

 quarantine regulations which conflict with Forest interests, or of 

 requests from a State official which conflict with the regulations of the 

 Bureau of Animal Industry, the district forester will endeavor to 

 secure a modification. If this can not be secured, the matter will 

 be submitted to the Forester for decision before final instructions are
