INTRODUCTION XV 



lieve, the goal toward which American forestry should and 

 will progress. 



My thanks are due to the officials of the Service des Eaux et 

 Forets, who have shown me without exception the utmost 

 courtesy and consideration. Conservateur de Lapasse, formerly 

 in charge of the Thirtieth Conservation, in collaboration with 

 Henry Dundas, English consul at AJaccio, kindly reviewed the 

 chapter on Corsica. Inspecteur Boutilly, chief of Forestation 

 and Management Plans for Algeria, was reviewing the chapters 

 on Algeria and Tunisia when the great war put a stop to his 

 Hterary work. Raphael Zon, U. S. Forest Service, made many 

 valuable suggestions after a painstaking review of the manu- 

 script. 



I am also indebted to W. P. Lawson, who edited the manu- 

 script and put it in shape for pubhcation, and to many others 

 for helpful suggestions. Both the metric and American systems 

 of measurement have been used so as not to detract from the 

 scientific value of the figures quoted. In giving equivalents oi 

 metric units, the nearest approximate value in the American 

 system has been used. Thus "lo feet" is more easily grasped 

 than " 118.08 inches" or "9.8425 feet," although each is an 

 equivalent of three metres. 



The utmost care has been taken to secure accuracy of detail 

 and to acknowledge in footnotes the sources of important data 

 and conclusions. If errors have, however, crept in, suggestions 

 for corrections and changes will be gratefully received and 

 promptly acknowledged. 



It has been thought best to group forestry in Corsica, Algeria, 

 Tunisia, and the Algerian Forest Code in one volume. This is 

 the more desirable, inasmuch as the matter treated may properly 

 come under the head of material illustrative of extensive forest 

 methods, while the remaining material, descriptive of methods 

 employed in forests in France proper, will take up the intensive 

 forestry in use there and be published later as a separate work.
