calculation of total per acre and the board con- 

 tent. 



For example : 



5 trees 18 inches in diameter X 5 = 25 

 trees 

 10 trees 12 inches in diameter X 5 = 50 



trees 

 15 trees 8 inches in diameter X5 = 75 

 trees 



The board footage would be calculated as fol- 

 lows: (All trees of the same diameter are as- 

 sumed to be of equal height in this example.) 



25 trees 18 inches in diameter 32 feet 

 high X 221 = 5,525 bd. ft. 



50 trees 12 inches in diameter 24 feet 

 high X 70 = 3,500 bd. ft. 



75 trees 8 inches in diameter (pole) 

 75 +■ 10 = 71/2 cords 



If the tract being appraised contained 20 

 acres of timber, the total volume would be: 



Saw timber : 



20 acres X 9,025 = 180,500 board feet 



Pole timber : 



20 acres X 7% cord 



150 cord 



The valuation of the timber tract is completed 

 by applying average acre values developed from 

 market data on the going rate or rates for tim- 

 ber of the species and general log size contained 

 in the subject to the total timber acreage. 



Content of stand : 



180,500 bd. ft. saw timber, one-half good 

 quality, one-half medium or below, white oak, 

 pine and hemlock mixed. 150 cords of mixed 

 pulpwood.
