* On account of the small amount of the thinnings and the short periods duiing which the 

 money from them would be invested, only 4 per cent, is allowed on them. 



Thinnings made at middle of decades yield about eleven cords 

 at twenty-five years, fifteen cords at thirty-five years, and ten 

 cords at forty-five years per acre. 



The minimum cost of producing lumber would be about $3.83 

 per 1,000 board feet, when a stand is about forty years old. 



The minimum cost of producing cordwood would be about 

 sixty-five cents a cord at an age of thirty years. 



These figures, which are conservative, indicate that planta- 

 tions can be expected to yield at least five per cent, gross or four 

 per cent, net after allowing one per cent, or ten cents an acre a 

 year, for taxes and protection. With regularly made and care- 

 fully executed thinnings, the yield would probably exceed that of 

 the irregularly Chinned stands on which the calculations are based 

 and the cost of production would be lowered: in other words a 

 higher interest rate would be obtained. 



In order for a plantation to yield five per cent, net or six per 

 cent, gross, allowing one per cent, an acre a year for taxes and fire 

 protection, the following returns, which are fair and reasonable, 

 must be obtained from stands of ditt'erent ages.
