While sandy soil allows fungi to spread within it more rapidly than clay, it offers the advantage of rapid seepage, and where the surface is ami3ly ventilated no difficulty should be experienced. (PI. X, figs 1 and 3.) The principal need is to have the yards so laid out that sur- face water will not ac- cumulate. Ordinary ashes are not consid- sidered a good filling or surfacing material, since they absorb moisture readily and hold it tenaciously, particularly when they are in a finely pulverized condition. Less finely divided mate- rial, such as coarse cinders, gravel, or slag, is better adapted on account of the rapid seepage. Moreover, wood-destroying fungi appear to grow through ashes quite readily when they are in a moist condi- tion. In fact, the writer has a record of one case where fungi developed lux- uriantly in a pile of ashes in the open when exposed to prolonged rainy weather. (PI. IX, fig. 3.) METHODS OF STACKING LUMBER. Lumber piled in the open must be al- lowed ventilation around the individ- ual pieces, and this In some instances, however, this necessity is ignored in certain.
