The material from the National Forests was received at the labora- 
tory in a green condition. The timbers from the yards of the coal 
company were partially air-dried. Upon arrival at the testing sta- 
tion all green material was barked and some of the specimens were 
soaked in water, while others were piled to air-season. The object 
of the water-soaking was to keep the timber in a green condition 
until tested or, in the case of the dead beams, to increase the moisture 
content to a point which would enable them to be compared with 
green material. The material cut green and water-soaked is used as 
the basis for making the comparisons with air-dry material.
