Logging Is The Important Part Of Forestry In Which Our Woods Are Treated And A Future Supply Of Timber Is Assured Or The Areas Are Left In Unproductive Conditions. It Is An Epic Story Of Courage, Great Hazards And Difficulties Overcome, Success And Failure In A Struggle To Provide Some Of The Necessities Of Mankind. A More Scientific Approach Has Been Made To The Problems Of Logging, And The Profitability Of Removing The Logs Of Different Species And Sizes From Our Woods Has Been More Accurately Determined. Mechanized Logging Has Made Important Advances Especially Feeling, Bucking, And Log Loading. Progress In Prelogging, Relogging, Integrated Logging, And Salvage Cuttings Has Presented New Phases Of The Industry That Are Important In Handling Our Forest Resources. It Is Hoped That This Book Will Help The Student And Possibly The Operator To Gain A Better Understanding Of Some Of The Logging Methods.
