Baur's investigations-'- bring out clearly this relation between 

 the number of sticks (or diameter of stick) and the solid volume of 

 the cord. 



From this table also follows that while we are dealing with logs 

 of fairly large diameter (6.0" to 6.8") an increase in the number 

 of sticks even from 94 to 126 per cord, an increase of 34 percent 

 (i. e., a small diminution in the diameter of each individual 

 stick), causes a drop of 6.40 cubic feet in the solid volume, 

 whereas practically the same drop is caused in the solid volume 

 of a stack of sticks of smaller diameters (3.5" to 4.7") by an in- 

 crease in their number from 205 to 378, or by an increase of 84 



per cent. 



3. Split Wood. 



Large sticks are often split to facilitate their drying and hand- 

 ling. After being split the sticks cannot be stacked as closelj- as 

 before and less wood is required to make the given stack. Split- 

 ting therefore reduces the amount of solid wood in the cord. 

 Stacks of split wood always contain less solid wood than stacks 

 of round wood of the same diameter. 



By splitting in two .sticks 21 inches long and 3.5" to 7" at the 

 small diameter, a stack increases (the solid wood per given space 

 consequently decreases) 6 per cent ; 21 -inch sticks thicker than 

 7 inches, 4 per cent ; 14-inch sticks, 3.5" to 7" thick, 5 per cent ; 

 and i4-inch sticks thicker than 7", only 2.5 per cent.f In other 

 words, the longer and thinner the sticks split, the greater is the 

 swelling of the stack, or, what is the same, the decrease of solid 

 wood in the given stack measure. 



^. Form of Sticks. 



The straighter and smoother the sticks the fewer air spaces be- 

 tween them, and, consequently the greater the solid contents of 

 the stack measure. For this reason the clear trunks of trees 

 yield more solid wood per given space than the tops and branches.
