A Text Book on Forestry 



In its relation to grazing grounds in the 

 West is an art and science on which there 

 has been no important body of comprehen- 

 sive, authorative information until the pub- 

 lication of 



Western Grazing Grounds and Forest Ranges 



By WILL C. BARNES 



of the Forest Service of the United States Department 



of Agriculture. 



This is an illustrated volume of 390 pages 

 which the author hopes "will be of use to 

 the young men who are taking up forestry 

 as their life-work." He discusses all the 

 practical problems with which employes of 

 the Forest Service in the 160,000,000 acres 

 of western grazing grounds have to con- 

 tend. Price, $2 prepaid. 



More than 140 original illustrations 

 graphically supplement the text. In the ap- 

 pendix a list of definitions of words and ex- 

 pressions in common use among western 

 stockmen is given, and the index is note- 

 worthy for its completeness. 



Adapted especially to the needs of stu- 

 dents and young men intending to enter the 

 Forest Service, colleges and schools giv- 

 ing instructions in forestry will find this 

 book invaluable for reference and class- 

 room. 



Mr. Barnes was for years a ranchman in 

 New Mexico. He has traveled extensively 

 in the forest ranges. He was at one time a 

 member of the New Mexico territorial legis- 

 lature. For the past few years he has been 

 connected with the Forest Service as In- 

 spector of Grazing.
