    Description

    This report presents the results of a study to determine the loss in volume and value of lumber when kiln drying and surfacing the production from ponderosa pine logs. The study measured (1) the reduction in volume due to trimming and culling dry lumber after surfacing, (2) the reduction in grade due to seasoning defects, (3) the reduction in grade due to failure of lumber to remain on grade because of manufacturing defects, and (4) the loss in value of the lumber resulting from the degrade.
