GROUND YARDING. 



Up to within the last year or so the bulk of the timber was yarded 

 by the ground system. Available information does not indicate how 

 much is handled by this system at present. That it has been replaced 



to a considerable extent by the high-lead and overhead systems is 

 clear. This system of yarding was long the one standard system, 

 and it is the system which p-resent-clay operators know best. For 

 this reason it is here treated at greater length than the other systems ; 

 indeed, the discussion of ground yarding is made to serve as a basis 

 for the discussion of high-lead and overhead systems.
