THE CAPACITY OF WOOD TO ABSORB MOISTURE AND 
ITS RELATION TO WEIGHT AND VOLUME. 
As has been stated, the weight and volume of different sorts of 
wood are largely affected by the water content. This is not only true 
of the wood of different species but is also true of the wood of each 
individual tree and of each part of each tree. 
The weight of wood is mainly dependent upon two factors: first, 
the amount of cellulose and other compounds constituting the wood 
substance, and second, the amount of water it contains. 
Lumber seasoned in the usual way and used or kept in a dry 
room retains on the average a little less than 10 per cent of moisture
