    Decay developing in decked western hemlock (Tsuga heterophylla) has caused considerable loss in pulp yields in the Pacific Northwest. The Oregon Pulp and Paper Co., which commonly decks hemlock logs through one summer and occasionally through two summers, cooperated with the Pacific Northwest Forest and Range Experiment Station in a study to determine (1) how much decay and pulp yield loss would develop during 1 and 2 years of storage and (2) whether the amount of such decay and loss could be decreased by continuous sprinkling with water during the dry summer months.
