MENSURATION, FINANCE, AND MANAGEMENT. 



A commission was appointed by the Gover- 



A Cubic nor of Maine to recommend a standard 



Log Measuring cubic foot rule for measuring logs. Its re- 



Rule. ]iort advises the use of a rule based on the 



length of the log to the nearest foot and the 



diameter at the center outside of bark. The total volume is read 



directly from the beam of a caliper graduated to show the cubic 



feet for various log lengths of different diameters. The amount 



of defect is left to the judgment of the scaler. For deduction of 



volume of bark, a general table is recommended, which is based on 



diameter at center of log and gives discount in per cent. This 



table was prepared from measurements of many trees of different 



kinds in different parts of the state, and is to be applied alike to 



spruce, pine, fir, hemlock, cedar and hardwoods. 



Per Cent, of Volume of Bark to Volume of Log.
