TIMBER STOEAGE IN THE EASTERN" AND SOUTHERN STATES.

the air to" infect whatever sound lumber may be in the vicinity. The 

 writer has seen scores of instances where small piles of rotting debris 

 have been scattered about lumberyards and even at times piled di- 

 rectly against sound lumber (fig. 10). Very frequently this debris 

 consists of old ties (fig. 11) or timbers from the tramway platforms. 

 In o.ther cases it may be yard stock which has rotted in storage and 

 has been left in situ or carted a few rods and discarded just beyond 

 the confines of the yard. One such mill yard was visited where 

 several hundred 

 thousand feet of pine 

 and hardwood lum- 

 ber had been thrown 

 into an adjoining rice 

 swamp in close prox- 

 imity to and extend- 

 ing for nearly a mile 

 along a row of lum- 

 ber stacks (see fig. 9). 

 Iji this same yard it 

 was also commonly 

 noted that sound 

 lumber fresh from 

 the saw was piled 

 upon the bases of old 

 lumber piles which 

 were thoroughly rot- 

 ted (fig. 12). 



Also in this yard, 

 as well as in a yard 

 in Mississippi, vines 

 were allowed to grow 

 up over some of the 

 lumber piles (fig. 13). 

 This is, of course, 

 highly objectionable, 

 since such vegetation tends to collect moisture and impedes venti- 

 lation. 



Such conditions as these are bound to be a serious menace to the 

 effective storage of lumber.

 storage in the yard shown in figure 11. Instead of burn- 

 ing the debris it was thrown into an adjoining rice 

 swamp. Fungi developing on this debris will again 

 infect the sound lumber. 



TRAMWAYS AND RAILWAYS. 



Practically all sawmills have a more or less extensive tramway or 

 railway system for the distribution of lumber from the mill to the 

 yard and other units of the plant (fig. 14). It is quite the uni- 

 versal condition that these structures harbor multitudes of various
