fills of earth instead of lumber debris, keeping down vegetable growth, 

 burning all rotting debris, keeping tramway structures and "stickers" 

 in sound condition, elevating all piles and piling openly, the author 

 especially favoring concrete foundation piers and treated skids. Out- 

 breaks of fungus disease should be promptly dealt with. The use of 

 sodium fluoride for dipping is recommended as superior to sodium 

 carbonate. 



A statement is given of the commoner fungi rotting stored lumber, 

 with illustrations. 



The author takes occasion to point out that the lumberman must 

 take more care with his product, especially structural timber, if he is 

 to hold his own in competition with other materials of construction. 

 This bulletin is well suited to help in the education of those engaged 

 in the lumber industry toward improvement of present practices ob- 

 taining in lumber yards.
