Description: Prior to World War 11, the U. S. Forest Service (Region 6) adopted the policy of appraising ponderosa pine timber with a standardized set of lumber grade recovery data obtained from representative pine mills which are known to use average care in manufacturing and marketing. Such data were derived by combining the results of several mill studies made about 20 to 25 years ago.
