IV PREFACE 



be scarcely recognizable, yet, for best results in teaching 

 students, definite theories and methods must be elaborated 

 and set off distinctly one from the other. 



No attempt has been made to cover in an absolutely com- 

 plete way and with full detail all branches of applied silvi- 

 culture. Such a work can well be postponed another decade 

 until American silviculture progresses further through the 

 formative period. On the contrary the purpose has been to 

 keep the text brief with the idea of producing a work to fill 

 an immediate need, containing such information as appears 

 applicable to-day or likely to be applicable (at least in some 

 parts of the country) in the near future. 



The lists of references following each chapter are not ex- 

 haustive but are intended to afford additional reading supple- 

 menting the text.
