COED WOOD. 



The figures given in Table 26 were derived by dividing the yields 

 in cubic feet for the different types, qualities, and average breast high 

 diameters at different ages, given in the preceding tables, by the 

 cordwood converting factors — that is, the corresponding number of 

 cubic feet per cord, given hi Table 41, Appendix. This method is not 

 entirely accurate, but the results are fairly close to the average for 

 each type and quality class.
