Table 27-137. — Volume loss, cubic feet and board feet, caused by cutting stumps above 

 height specified in a logging contract (Patterson 1977)' 



'These volumes were computed by considering the excess stump height as cylindrical with no 

 taper; volume losses in most pine-site hardwoods, which have considerable butt swell near stump 

 height, would be greater than the tabulated values. 



^Excessive stump height = total stump height minus target height specified in the logging 

 contract.
