They are now in a state when their annual increase in growth 

 and value is very great. At the end of sixty years, the inter- 

 vening period from forty has probably disposed of 150 trees 

 per acre, at an average price, we shall assume, of only one 

 shilling per tree — after deducting expenses and allowing for 

 dead trees — giving L.7, 10s. per acre. We have now 300 

 trees remaining for each acre, and shall suppose that they 

 consist of Larches and Scots Firs equally. Of course, there 

 wiU be considerable variety in the size, but, assuming that 

 each acre contains 



Fifty Larches, worth on an average only 5s. 



each, L.12 10 0 



And fifty Scots Firs, worth 2s. 6d., . . 6 5 0 



With the remaining two hundred trees, at say 



on an average of only Is. 6d., . . 15 0 0 



We have a total value per acre of . L.33 15 0 



The result of the foregoing estimate would stand thus : — 

 Original expense of planting and enclosing, 



L.l, 4s. 9d. per acre, or say . . . L.l 5 0 

 Compound interest at 5 per cent for thirty years, 

 the thinnings to that date being held as an 

 equivalent for the expense of cutting, &c.. 5 8 0 



Total per acre, . . . L.6 13 0 



For the period of the wood's age, between thirty and 

 forty, we held the thinnings as worth 10s. per annum, per 

 acre ; but as the Reporter would rather have his estimate 

 below than above the truth, we shall place the return for this 

 period simply as equal to the current interest then accruing.
