394 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE. 



other permittees were freed from claims for damages, which in many 

 States might follow the intrusion upon the private lands of stock 

 grazed under Forest Service permits. Thus the plan resulted in the 

 fullest and most economical use of the entire range. The permits of 

 tliis class numbered 1,205, and allowed the grazing of 57,594 head of 

 cattle and horses, 989 swine, and 392,592 head of sheep, and goats. 

 The owners of this stock waived the right of exclusive use of 2,418,202 

 acres of private land. The number of permits issued fell off 8.43 per 

 cent, the number of cattle and horses mcreased 5.74 per cent, sheep 

 and goafs 4.89 per cent, and the number of acres of land increased 12 

 per cent. 



Under the cooperative agreement previously in force with the 

 Atchison, Topeka & Santa Fe Railroad Co. the Forest Service con- 

 tinued to advise the company as to the number of stock which may 

 safely be grazed on its lands within the Zuni National Forest. An 

 agreement is also in force with the Northern Idaho Forestry Associa- 

 tion, composed of representatives of the State of Idaho and private 

 owners of 94,000 acres of patented land in the Palouse division of the 

 Coeur d'Alene Forest, under which persons grazing stock upon the 

 Palouse division pay a part of the grazing fee to the Northern Idaho 

 Forestry Association and a part to the Forest Service in proportion to 

 the respective holdings of the association and the Ser\dce. The 

 Weyerhaueser Land Co. and the Northern Pacific Railroad Co. con- 

 tinued their informal cooperation with the Forest Service. While 

 under no agreement to do so, both of these companies in leasing their 

 lands within the National Forests give preference to Forest Service 

 permittees who will waive the right of exclusive use in exchange for a 

 permit under Regulation G-19. The Northern Pacific Co. also makes 

 a practice of referring all applications for the lease of lands within 

 National Forests to the district forester to learn whether the proposed 

 lease will be detrimental to Forest interests. 



Protection Against Disease. 



Permittees who grazed their stock during a part of the year on out- 

 side ranges where communicable diseases injurious to live stock were 

 known to exist were required to submit the stock to rigid inspection 

 by representatives of the Bureau of Animal Industry, and to present 

 certificates showing freedom from disease before placing the stock 

 upon the Forest ranges. This requirement has been in efTect for 

 a number of years and as a result all but three of the National Forests 

 are free from most forms of communicable diseases fatal to hve stock. 

 The principal inspection required during the year was to prevent the 

 grazing of sheep infected with scabies upon certain Forests in Arizona, 

 California, Colorado, Nevada, New Mexico, amil Utah, practically 

 the same area as that where inspection was required during the pre- 

 ceding year. By close attention to prevent the spread of hp and leg 

 ulceration among the sheep occupying the National Forests in the 

 State of Wyoming, it was brought about that no sheep left the Forests 

 in the fall of 1910 affected with tliis disease. The discovery that 

 cattle to be grazed upon the Routt Forest in Colorado and the 

 Deschutes and Fremont Forests in Oregon were infected with cattle 

 scabies necessitated an inspection of stock entering these Forests 

 and the enforcement of dipping requirements prescribed by the
