each pole as near as possible to the point of failure, immediately 
weighed, and later dried to constant weight at the temperature of

pressed in per cent of moisture. 
The length, weight, and diameters of the poles were obtained just 
before testing. The age, rings per inch, per cent sap, and per cent 
summerwood were obtained after test from a section cut near the
