PREFACE TO THE SECOND EDITION. 



The first edition of my translation of Dr. Hess' Forst- 

 scHDTZ, published in 1895, is now exhausted. I have there- 

 fore revised it and have increased the number of pages from 

 593 to 712, and the number of plates from 259 to 300. I 

 have also added a portrait and short biography of Dr. Hess, 

 both of which are taken from a biographical sketch written 

 by Forstmeister F. Kraetzl, and published in 1902, in the 

 53rd annual volume of " Yerhandlungen der Forstwirte von 

 Mahren und Schlesien." I have also added an index, although 

 the table of contents appeared to me, when publishing the 

 first edition, as a suflicient substitute. 



The French have never produced .an independent work on 

 forest protection, but have included the subject in works 

 on silviculture, entomology, mycology, &c. ; the rapid sale, 

 however, of my first edition has shown that English-speaking 

 foresters require a separate treatise, while such a treatise is 

 part of the scheme of Schlich's Manual of Fokestry, of 

 which this book forms Volume lY. I have been asked why 

 I do not write an original book on the subject. It would 

 have been impossible to do so without borrowing largely 

 from German authors, and it therefore appears preferable 

 to continue my former plan of translating the best German 

 work on the, subject. 



Most of the additional matter contained in the present 

 volume, as compared with the former edition, is due to 

 additions made by Dr. Hess, in the fourth edition of his 

 FoRSTScHUTz, published in 1900. He has also revised the 

 scientific nomenclature of insects and fungi, and has correct^
