Logging: The Principles and General Methods of Operation in the United States. E-book. Formato PDF - 9780243740468

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 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 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 facilities 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.
