PREFACE 



The "Practice of Silviculture" has been prepared for use 

 as a text book to cover a field at present unfilled. So far as

 fifteen years' experience in applying silviculture on forest 

 properties and in teaching the subject, that, while, in the 

 application of silviculture, methods as given in books often 

 must be sq^ modified and changed to fit local conditions as to
