The International log rule for 1/4-inch kerf the tabular values of which were established by Judson F. Clark in 1920 is now officially recognized by the Forest Service as an optional rule for scaling government timber. Extensive sawing tests in New England reveal an underrun of less than 2 percent for pine, and in the South show its adaptability for scaling small logs. It is generally accepted in the South and elsewhere as the standard for timber estimating and growth measurements but is converted into Doyle rule values as well. The defects of the Doyle rule are set forth and the source of error restated. An important modification of the Doyle rule for scaling small logs is explained.
