Abstract
In New Jersey the Doyle rule is applied by taking the diameter at the middle of the log inside bark and rounding off fractions of an inch to the nearest inch. With 154 hardwood logs averaging 17.4 inches in middle diameter and 30 feet in length, this method of scaling, which is the one prescribed in Scribner's Lumber and Log Book, gave board-foot contents slightly in excess of those given by the International 1/4-inch rule. The author believes that the Doyle rule gives satisfactory results when properly applied under the conditions which prevail in New Jersey and where sellers of stumpage have access to technical guidance from the state forester.
