PREFACE 



This volume has been prepared as a text-book for use in 

 Forest Schools. The subject is broad in scope and an attempt 

 has been made to cover only the more important features of 

 operation; hence the innumerable variations in equipment and 

 method which are pecuHar to different forest regions are not 

 included. Of the many minor industries related to logging, 

 only two of the more important are treated, turpentine orchard- 

 ing and tanbark harvesting. 



One of the most difficult and costly features of a logging 

 operation is the movement of the timber from the stump to 

 the manufacturing plant and the chief facihties and methods 

 for doing this are discussed at length, especially logging rail- 

 roads. The greatest emphasis is laid on features about which 

 there is not much written material available, while engineering 

 subjects such as road surveys and the measurement of earth- 

 work and rock-work are omitted because they are treated in 

 numerous other text-books. 



In preparing this volume the author has consulted freely 

 many of the lumber trade journals, especially The Timberman 

 and the American Lumberman; the various pubhcations of the 

 U. S. Forest Service; "Earthwork and Its Cost," by Gillette; 

 articles in numerous periodicals, especially the Forestry Quar- 

 terly; and unpublished manuscripts. 



Many of the photographs and drawings are original; the 

 others have been secured from various sources and credit 

 for them has been given whenever their origin was known. 

 The data on timberland ownership are from a report on the 

 Lumber Industry by the Bureau of Corporations of the Depart- 

 ment of Commerce and Labor. The log rules in the Appendix 

 were taken chiefly from the Woodsman's Handbook, by Graves;
