14 PREFACE. 



The silvicultural notes, largely tentative in character as they 

 must necessarily be, are intended to refer only to the bearing of 

 each species in North Carolina. 



Besides Mr. Ashe, to whose notes I am indebted for the descrip- 

 tions of the root systems and for other material, and myself, many 

 others have joined in the work, but it would carry me too far to 

 acknowledge their services in detail. I must ask them to accept 

 this general expression of my sincere appreciation of their assist- 

 ance. GiFFORD PiNCHOT. 



New York, Nov. 26, 1896.
