From a table showing the contents in cords, by either of the above 

 standards, for trees of each size class, a second table can be constructed, 

 giving the number of trees of each class required to produce one cord 

 of wood. The cubic contents of a cord, according to the ratio adopted, 

 is divided by that of the tree as shown in a volume table. This gives 

 the number of trees required. These tables may be of value in estimat- 

 ing cordwood, by making rough counts. The principle involved is 

 the same as that used in estimating board feet by log run (§ 120).
