TIMBER STORAGE IN THE EASTERN AND SOUTHERN STATES. 
These bodies may be borne on short stalks on the mycelial threads 
(conidia), or the mycelium itself may break up into short cells 
(oidia), or specialized thick-walled cells (chlamydospores) may form 
within the mycelium. The last kind of spore, on account of its 
thicker wall, is adapted to withstand unfavorable weather conditions ; 
the two former kinds are usually thin walled, minute, and readily 
blown about by the wind. 
With these fundamental facts in mind, let us now turn to a discus- 
sion of the present conditions under which timber is stored and see 
wherein these conditions contravene the known facts regarding the 
development and 
spread of decay-pro- 
ducing fungi. 
HANDLING TIMBER 
AT SAWMILLS. 
The practice at 
different sawmills va- 
ries widely. A few 
of the larger mills, 
particularly in the 
longleaf -pine belt, put 
almost their entire 
cut through the dry 
kiln and then store it 
under closed sheds. 
This practice is to be 
highly commended, 
and if the storage 
sheds are well 
drained and properly 
ventilated beneath, no 
trouble from fungi 
should be experienced. 
However, comparatively few mills have the facilities for handling 
their product in this approved fashion, and the great majority have 
kiln capacity for only the B and better grades of lumber. The re- 
mainder of the output is piled in the open yard (fig. 1), the higher 
grades of lumber often being dipped in sodium bicarbonate or sodium 
carbonate to prevent blue stain. 
Some few mills of the poorer class and smaller type dispense with 
both kiln drying and dipping and pile their entire green stock in the 
open yard. The few mills of this type which the writer has visited 
are usually also very lax in their methods of piling and of yard 
sanitation.
