Canadian Standard Rules. 
The Canadian Standard Rules are based on logs 12 feet instead 
of 13 feet in length. These two standard rules are now used less 
than formerly. The units on which they are based are 12-foot 
logs, 21 and 22 inches, respectively, in diameter. These rules are 
used in the same way as the American standard rules already 
described. 
The Canadian 22-inch standard log contains 243 board feet, and 
the 21-inch standard log contains 217 board feet by the Doyle Rule. 
CORD MEASURE. 
Firewood, small pulpwood, and material cut into short sticks 
for excelsior, ete., is usually measured by the cord. A cord is 128 
cubic feet of stacked wood. The wood is usually cut into 4-foot
