1 Cost of establishing a loblolly pine stand, either by natural or artificial reproduction. 



2 Three cents per acre annually for administration (including fire protection), and 6 mills on the dollar 

 (full valuation) annually for taxes, which is above present average tax for the region. 



3 Stumpage value as given in Table 14, less original cost of formation and total cost of administration and 

 taxes. Where no net profit is shown, a loss is i ndicated. 



* Calculated by formula p=100 ( -J "t ~ — l) , where p= compound interest rate, m=number of years 



or rotation, <S=stumpage value at n years, i=cost of land, F=cost of formation, and A=cost of adminis- 

 tration and taxes in n years at 6 per cent compound interest.
