TABLE 76. INCREASE IN THE COST OF MANUFACTURING LUMBER WITH DECREASE IN THE SIZE OF 



THE Loa. 



It would cost 15 per cent more to manufacture lumber from 10-inch 

 logs than from 13-inch logs, consequently, disregarding the overrun, the 

 larger logs might be regarded as 15 per cent more valuable than the 

 small ones even if the value of the lumber per 1,000 feet were the same 

 from logs of both sizes. 



RELATIVE VALUE OF TREES FOR DIFFERENT USES. 



The wood of loblolly pine is commonly measured either as logs, 

 scaled by Doyle-Scribner rule, or as cords of 128 cubic feet with the 

 bark on, or as cords of 160 cubic feet with the bark peeled. Piling is 

 now usually purchased on the same basis as logs for lumber the diam- 

 eter of the log being taken in the middle (the average of the two ends) 

 and the volume of the log scaled by a log rule. Since only the straightest 

 and longest bodied trees are used for piling, the stumpage value of tim- 

 ber selected for this use should be higher than that of the same size sold 

 for milling purposes. Veneer is generally cut from logs 16 inches and 

 over in diameter. In smaller logs there is too large a proportion of 

 \v;iste in the wood which is left in the core. Small coarse grained and 

 somewhat knotty stock can be used for crate veneers, but for panel veneer 

 fine grained timber, either free from knots or with only a few knots, is 

 desired. Pine veneer stock is purchased entirely by log scale, and its 

 value, consequently, is that of the appropriate grades and sizes of logs 

 which are purchased. (Tables 50 to 54.) (Plate XII, C shows excel- 

 lent veneer logs.) 



Only small timber is purchased by the cord. Bolts for boxes and 

 crates, staves and headings are purchased by the cord with the bark on. 

 Pulpwood stock is purchased by the cord generally with the bark re- 

 moved or rossed. (For proportion of bark see Table 34.) The relative 

 value of small trees of different sizes for cordwood, both rossed and 

 with the bark on and for sawtimber is shown in Table 77. Stumpage 

 values in the table are placed at $1.00 per thousand feet for lumber ; at 

 $1.00 a long cord for wood measured after it is rossed, dried and racked; 

 and at $1.00 a cord for wood measured with the bark on. To use this 

 table it is necessary to multiply the volumes which are given in the table 

 for trees of each diameter by the relation of the stumpage at $1.00 to the
