This method requires one more measurement than the previous, and 

 is therefore not as rapid for ordinary work in commercial scaling. It 

 is, however, a very convenient formula for determining the contents of 

 logs where it is not possible to take the measurement at the middle, as on 

 logs piled on a skidway. 



Solid cubic contents of logs (in cubic feet)

The most common methods of determining the cubic contents of 

 square timber that may be cut from round logs is the so-called Two- 

 thirds Rule, and the Inscribed Square Rule.
