TIMBER STORAGE IN THE EASTERN AND SOUTHERN STATES. 21 



This question of the sanitary handling of the piling sticks is of 

 very great significance, particularly in regions of high humidity, 

 where every precau- 

 tion must be taken 

 to safeguard stored 

 lumber. Plate III, 

 figures 5 and 6, shows 

 such infected sticks 

 found in Florida 

 and Tennessee lum- 

 beryards, wdiere sev- 

 eral species of wood- 

 clestroying fungi 

 were frequently 

 noted in the piles. 



Wlien one keeps in 

 mind the fact that 

 the soil in and about 

 lumberyards often 

 becomes, in the 

 course of time, thor- 

 oughly inter mixed 

 with sawdust and 

 partially decomposed woody matter which offers a fertile field for the 

 development of wood- destroying fungi, the necessity of keeping all 



sound material out 

 of contact with it be- 

 comes very evident. 

 In cases where saw- 

 dust and bark or 

 wood debris are used 

 to produce artificial 

 fills the danger is 

 further increased. 

 Such filling mate- 

 rials are not infre- 

 quently used. 



Such situations in- 

 troduce the further 

 question as to what 

 material should be 

 used for filling in 

 low portions of the yards. While the material used will necessarily 

 be governed largely by local conditions, it is the opinion of the writer
