B. E. Fernow, Chief of the Department of For- 

 estry in the United States Department of Agricul- 

 ture, in a paper entitled " What is Forestry ?" * 

 says, on page 15 : 



" Forestry in a wooded country means harvesting the wood 

 crop in such a manner that the forest will produce itself in 

 the same, if not in superior, composition of kinds. Keproduc- 

 tion, then, is the aim of the forest manager, and the difference 

 between the work of the lumberman and that of the forester 

 consists mainly in this : that the forester cuts his trees with a 

 view of securing valuable reproduction, while the lumber- 

 man cuts without this view, or at least without the knowledge 

 as to how this reproduction can be secured and directed at 

 will. The efficient forest manager requires no tool other than 

 the axe and the saw, the planing-tools being only needed to 

 correct his mistakes, but he sees them differently from the 

 lumberman."
