VOLUME TABLE OF MERCHANTABLE CORDS. 
In order to convert solid cubic feet into cords it is necessary first to divide by 128 
the number of cubic feet in one cord, and then to divide by a factor which shall 
represent the relation between solid and stacked wood. In Germany this factor has 
been found from a large number of experiments to be 0.65 for round billets stacked 
in the woods. In consequence of irregularities in shape due to roughness of the 
bark and to swellings where the branches entered the trunk, this figure seems to 
give results too large for rossed billets. For the case in hand, 0.7 is more accurate. 
When the results of dividing the number of cubic feet (found in Table III) by the 
factor 0.7 are compared with those obtained by dividing the values in the table of 
standards by 2.92, which is the number of standards in one cord, determined by the 
Santa Clara Lumber Company from several thousand cord measurements, they are 
found to correspond almost exactly. After this confirmation of the factor 0.7, it 
was adopted, and the table of cords was constructed by dividing the values in the 
table for cubic feet by 128 and the result by 0.7.
