25 Del. C. § 1402: Method of ascertaining value of trees removed.

In the absence of a more accurate means of ascertaining the value of trees removed in a timber trespass, the court may accept that figure which shall be arrived at by accepting the diameters of the stumps of the severed trees measured inside the bark as the assumed diameter of the trees measured outside the bark at 41/4 feet above the ground and apply the values given for gross tree volume as published in U.S.D.A., Farmers Bulletin No. 1989, and the numerous privately published forestry publications which give board foot volume contents of timber trees based on the International Long Rule formula.
