Grazing Estimate to be Based upon Normal Conditions. 



Since the Secretary of Agriculture's authorization is based upon 

 the supervisor's estimate of the grazing capacity of his Forest, the 

 estimate should be carefully prepared. The first step should be to 

 divide the entire range among the different classes of stock. Having 

 ascertained the area of range available for each class of stock, the 

 number it will support will be determined. This estimate should, 

 so far as possible, be based upon the normal condition of the range 

 and should not be varied from year to year to meet departures from 

 normal, except as a measure of forest protection. Increased capacity 

 due to natural conditions known to be abnormal should not be 

 accepted as grounds for increases in the numbers of stock. The 

 allotment should in every case be low enough to prevent damage to 

 the Forest. 

 Land Included in Estimate. 



The carrying capacity of all Government lands within the National 

 Forests not otherwise reserved or closed to grazing for protective pur- 

 poses, unsurveyed school sections, and unsurveyed lands within both 

 the primary and the indemnity limits of railroad grants should be 

 considered in the estimate. 

 Lands not Considered in Estimate. 



In preparing estimates the supervisor will not consider the carrying 

 capacity of the following classes of land: 



Patented lands of any character. 



Subsisting mining locations. 



Entries under United States land laws. 



Indian allotments. 



State lands granted or selected under acts of Congress. 



Surveyed and selected railroad lands within either the pri- 

 mary or indemnity limits or other selections provided for 

 by law. 



Subsisting squatter's claims. 

 Points to Consider in Fixing Grazing Periods. 



Grazing periods will be established for each National Forest to 

 meet the general needs of the people and to secure an economical use 

 of the forage. An endeavor is made to make them meet local condi- 

 tions and to allow grazing when the particular range in question can 

 be used to the best advantage without injury to the Forest. It is
