 BEEN LEFT BECAUSE THEY WILL YIELD LARGER RETURNS WHEN THEY REACH TIMBER SIZE. 



1 mine the actual contents of at least a few 

 \ trees in each diameter class. This may 



be done by selecting trees of as nearly 

 ; average form as can be found; cutting 

 ; them down and then working them in 

 such a way as would be done for the 



market. Then each log, if logs are cut, 

 ! can be scaled separately, with the 

 | ordinary log rule used for scaling logs 

 : in that district, and the total board 

 ; foot contents thus determined. Cord- 

 < wood, ties or poles may be estimated 



either by working the tree into those 

 products and determining the actual 

 amount thus obtained; or by determin- 

 ing the solid cubic foot contents, and 

 allowing such converting factors, as for 

 example, ninety cubic feet to one cord 

 of wood. Where the cubic contents are 

 measured, the diameter of each piece 

 is measured at both ends, and the 

 average diameter is taken ; the area of a 

 circle of that diameter is found, and 

 that area multiplied by the length of
