To determine the moisture content, a 1-incli section was cut from 

 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
