These bodies may be borne on short stalks on the mycelial threads (conidia), or the myceliimi 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 w^alled, 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 contra^â ene the known facts regarding the d e ve 1 o p m e n t 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 P62F Fig. 1.âBird's-eye view of a clean lumber-mill yard i Arkansas, showing the usual method of open Please
