Factors InHicencing the Vohivie of Solid Wood m the Co?'d. 131 



but having sticks of dififerent lengths, diameters, and shape, un- 

 less the actual solid volume of the two stacks is known. It is 

 extremely desirable, therefore, to be able to tell how much solid 

 wood is in a cord made of sticks of given length and diameter. 

 Only by knowing this can one avoid paying the same amount of 

 money for the same number of cords and getting different 

 amounts of solid wood. 



An attempt is made here to pre.sent tables in which the solid 

 volume of wood in a cord can be found. Of all the factors in- 

 fluencing the amount of solid wood only the length and thickness 

 of the stick are taken into account as being of greater importance 

 and uniform in their effect. The rest are more variable in their 

 influence and are, therefore, less easily computable. 



The wood is divided into several classes according to its thick- 

 ness. In the first class are sticks more than 5.5" in diameter at 

 the small end. Such sticks are usually derived from the lower 

 part of the trunk ; they are free of branches and cylindrical in 

 shape. The best pulpwood belongs to this class. 



The second class contains sticks 2.5" to 5.5" in diameter. This 

 and the first class are most frequently found together. Most 

 pulpwood is a mixture of these two classes. 



To the third class belongs wood i.o" to 2.5" in diameter. This 

 and the second class mixed together furnish most of the extract 

 wood, firewood, etc. 



Table I gives the solid volume of a cord containing 128 cubic 

 feet of stacked wood for sticks 10" to 14' long. Table II that of 

 stacks 4 feet high, 8 feet long, and 10", 12", 14", 16", etc., wide. 



In order to find the solid volume of a stick length not given in 

 Table II, take the stick length nearest it, divide its solid con- 

 tents by its length, and multiply the quotient by the log length 

 desired. Thus, if it be required to find the solid volume of a 

 cord of 13-inch wood, 4 feet high and 8 feet long, divide 23.50 by 

 12 and multiply the quotient by 13, or divide 27.32 by 14 and 

 multiply by 13. The result in either case will give the solid 

 volume for the required stick length. 



The figures given in the table are average figures, and as such 

 are subject to changes in accordance with local conditions. If, 

 for instance, the majority of the trees cut into cordwood are more 

 than 12.0" in diameter breast high, the solid volume of the cord 

 may be raised about 5%. Should the majority of the trees be no 

 larger than 5", the solid volume of the cord may be reduced about
