100 OUR NATIONAL FORESTS 



and the necessary care and thoroughness is given 

 to them which could only be given them at a fully 

 equipped experiment station. All grazing inves- 

 tigations on the National Forests are carried on 

 under the direct supervision of this station. 



The seeding of depleted grazing lands is ac- 

 complished either by direct artificial seeding or 

 through rotation grazing. Under the former 

 method the seed of native or foreign grasses and 

 other range plants are sown on the range, in the 

 attempt to increase the forage crop. By rotation 

 grazing, that is, permitting the stock to feed first 

 on one area and then on another, the grasses and 

 forage plants are allowed to recuperate from the 

 effect of grazing and allowed to reproduce. The 

 stock is excluded from one area while the seed is 

 maturing, and after the seed has matured and be- 

 come scattered on the area the stock is allowed to 

 graze on it. As the stock feeds on the plants it 

 tramples the seed into the ground and thereby fur- 

 nishes favorable conditions for the germination of 

 the seed. There are few parts of the National 

 Forests that cannot be completely regenerated by 

 the adoption of either one or the other of these two 

 methods.
