ranges of the Southwest and the Pacific slope can be only ap- 

 proximately estimated. 



Although nearly all of the successful introduced plants are 

 adapted to the humid or semi-humid regions of the United 

 States, it is not improbable that other foreign species might be 

 equally well adapted to mountain lands and arid sections. 

 Until suitable introduced plants are discovered, however, range 

 managers must content themselves with the improvement of 

 the range through the revegetation of the native forage crop. 

 Possibilities along this line have been adequately demonstrated, 

 and the results are highly encouraging.

 revegetation may be hastened appreciably by scattering in
