The trees in this table are really of good length. Meas¬ 
urements on short mountain timber are not available. 
Cedar Shingle Bolts. Very defective trees, the break¬ 
age of logging operations, and sometimes the whole 
usable contents of trees above about 20 inches in breast 
diameter are largely utilized in this form. The bolts are 
cut 52 inches long and the larger pieces split; they are 
then piled and measured in the cord 8X4 feet. In 
present practice from 18 to 25 bolts make a cord which 
careful measurement has shown to contain of solid wood 
about 70 per cent of its outside contents. A cord is 
equivalent to from 500 to 700 feet log scale, less in the 
smaller sizes of timber.
