PREFACE TO THE SECOND EDITION 



The reception accorded the first edition of this work has 

 encouraged me to prepare a revised and enlarged second edition. 

 In doing so I have profited from four main sources, not open 

 at the time of writing the original text. 



The first of these is the work of the Committee on Termi- 

 nology of the Society of American Foresters, which has gone far 

 to standardize the nomenclature. It has been my privilege to 

 serve as chairman of the sub-committee on Organization, 

 Mensuration, and Management, and I have derived the greatest 

 help from the hearty cooperation of my colleagues both within 

 and without the Committee. The terminology of the second 

 edition has thus been brought into accord with the best usage 

 of to-day. 



The second great source of assistance is the helpful criticism 

 engendered by the first edition. While it has not proved 

 expedient to adopt all the suggestions, nevertheless, the faults 

 noted have been corrected just so far as possible without de- 

 stroying the originality and coherence of the work. In a text 

 on forest organization, a detailed discussion of the apphcation 

 of silvicultural methods, of the pros and cons of various kinds 

 of rotations and similar material of a general character does not 

 seem in place, any more than would a didactic attempt to say: 

 such and such a method of determining the cut should be used 

 with such and such species, or forests. The time is not yet 

 ripe for such generalizations; they must wait until the practice 

 of forest management in America has advanced further than 

 to-day. A new feature of this edition is the " Correlation of 

 Silvicultural Methods and Methods of Determining the Cut," 

 which is as far as the author feels justified in going along these 

 lines. 



The third source of assistance has been the experience of
