Note the orderly arrangement and clean yard, conditions which are all too rare in the pulp industry Fig. 3.—Bark and fragments of rotten wood which have been shaken down from the conveyor. Such detritus readily absorbs and holds moisture from rains and, in the case of any but water-soaked wood, promotes decay. Fig. 4.—Bark and rotten wood at the base of a pile of 2-foot spruce and balsam stored for about one and one-half years. New rossed wood has been piled on this old, thoroughly infected base. Considerable loss from decay in the new wood may be expected from this source. Before starting new piles the old wood should be utilized and the surface of the ground cleared of all infecting material.
