PREFACE TO FIRST EDITION 
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 opera- 
tion; hence the innumerable variations in equipment and method 
which are peculiar to different forest regions are not included. 
Of the many minor industries related to logging, only two of 
the more important are treated, turpentine orcharding and tan- 
bark harvesting. 
One of the most difficult and costly features of a logging ©pera- 
tion is the movement of the timber from the stmnp to the manu- 
facturing plant and the chief facilities and methods for doing this 
are discussed at length, especially logging railroads. 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 publications 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terly; and unpublished manuscripts.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 Department of Commerce 
and Labor. The log rules in the Appendix were taken chiefly 
from the Woodsman's Handbook, by Graves; two tables of cubic 
contents are from the Forestry Quarterly, and one from the Manual 
for Northern Woodsmen, by Cary. 
The author wishes to acknowledge his indebtedness to all who
