This shows that, in spite of the greatly increased yield, the forests 

 are now much more valuable than fifty years ago. The net 

 returns (after deducting all expenses) show the following results 

 per acre and year : 



During the period 1817-26 . . 4-0 shillings. 



I may add that the average receipts per cubic foot of wood 

 were 2"ld. in 1817 and 4-5d. in 1900, a rise equal to 114 per 

 cent., while the above figures show tliat the net receipts per acre 

 have during the same period risen by 462 per cent. 



Surely here is an incontrovertible proof of what scientific and 

 systematic management of woodlands can achieve ! 



There are many other important points connected with this 

 subject which I should have liked to discuss, but want of space 

 prevents my doing so. Enough has, I hope, been said to 

 demonstrate the extreme importance of the problem, and the 

 simple steps imperatively called for to solve it.
