Fig. 1.— Representative samples of infeeted spruce and balsam taken from the base of the pile 
shown in PI. V, fig. 4. These are badly decayed and will be almost worthless when utilized 
Fig. 2— Pile of pulp wood equipped with spray nozzles spaced 30 feet apart each way and 
delivering 2 quarts of water per minute. The nozzles should be higher, about 5 to 10 feet 
above the wood, in order to cover the pile. For the most efficient results and the best dis- 
tribution of moisture, spray heads should be selected which break the water into the finest 
possible spray. (After Iloxie) 
Fig. 3.— Piles of 8-foot spruce and balsam up to 35 feet in height placed directly on the ground 
and closely massed. This wood was found very severely decayed after three years' storage 
Fig. 4— Ranked piles of 8-foot tamarack, about 3. r > feet high, separated by a space of about 
2 feet at the base, which permits considerable air circulation. Higher foundations would 
be advantageous
