ting systems, which will necessarily later be replaced by 

 better methods, are described in considerable detail; and 

 more space is given to the primitive application of the 

 shelterwood system than to its fully developed practise 

 in Europe. A number of the European modifications 

 of the various silvicultural systems have not been men- 

 tioned at all, as they would have at present only a very 

 limited application in this country. 



So far as possible I have endeavored to use such tech- 

 nical terms as have been already established. The ter- 

 minology has been made to conform in most instances to 

 that given by Mr. O. W. Price in Bulletin No. 61, U. S. 

 Forest Service. There has, however, been some devia- 

 tion from that list, and several new terms have been used 

 where those in common usage seemed inadequate. 



I am indebted to the Forest Service for the majority 

 of photographs used in the book.
