INCREASING THE YIELD. 49 



not be removed when labor items, including delivery on cars, amount to 

 more than this. 



Where trees are short bodied and low grade, but sound, a large portion 

 of the timber being of unprofitable character, the tree should be held, 

 since some growth is taking place and this, added to the appreciation in 

 the price of stumpage which is rapid in the case of low grade timber (see 

 Table No. 12), will eventually assure the removal of such trees at a profit. 



Selling timber in the most profitable form. The wood of second 

 growth yellow poplar is commonly measured either as logs scaled by 

 Doyle-Scribner rule, or as cords of 128 cubic feet of piled wood with the 

 bark on, or as cords of 160 cubic feet of piled wood with the bark peeled. 

 It is frequently desirable to determine before cutting the most profitable 

 form in which to market small trees. Veneer is generally cut from logs 

 16 inches and over in diameter, and is measured by the cubic feet of solid 

 wood in the log. There is consequently no difficulty in ascertaining the 

 relative value of logs marketed for veneer stock, and measured by a log 

 scale. 



The relative value of small trees of different sizes for pulp cordwoocl 

 and for saw timber is shown in Table 18. Stumpage values in the table 

 are placed at $1 per 1,000 feet for lumber, measured by Doyle-Scribner 

 rule; and at $1 a cord of 160 cubic feet for wood measured after it is 

 rossed, dried, and racked. 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 to the actual stumpage price which is of- 

 fered, using as a basal diameter the diameter breast-high of the average 

 sized tree on the tract. For. example: if board measure stumpage were 

 worth $1.50 per 1,000 feet, the volume which is given for the average tree 

 in the board-measure column should be multiplied by 1.50. If the cord- 

 wood stumpage measured after peeling were worth 50 cents a cord, the 

 value given of the average sized tree which is under this head should be 

 multiplied by .50. A comparison of the two resultant figures will show 

 in which form the timber could be marketed most profitably. 



Table 19 shows the number of trees required to make a cord of 160 

 cubic feet after they are peeled, split, and dried.
