ON PLANTING WASTE LAND FOR PROFIT. 193 



Burckhardt's figures again for the expected yield from thinnings, 

 these may be estimated at about 24 cubic feet per acre per 

 annum ; making a total for thinnings during a ninety years' 

 rotation of 2145 cubic feet (true contents), or about 1685 cubic 

 feet British measurement, worth about 4d. per cubic foot, or 

 ^^28 in all. 



The number of Scots pine per imperial acre at ninety years 

 should be about 230. Each of these would average about 18 

 cubic feet, yielding a total of 4140 cubic feet of timber, worth 

 about 5d. per cubic foot, or ;!^86, 5s. in all, and making the 

 total returns about £114, 5s. per acre. Allowing for expenditure 

 as before, this leaves an average annual revenue of 24s. 4d. 

 per acre. 



The above estimates as to the market price for spruce and 

 pine are slightly below those at present obtainable in this 

 district. 



It is unnecessary to make similar estirhates of the expected 

 yield from other trees ; but it may be asserted that the net annual 

 revenue to be derived from well-managed plantations of larch, 

 or from oak, ash, elm and other hardwoods will probably be 

 at least one-third more than that derived from either pure crops 

 of Scots pine or spruce. And it may further be asserted that 

 land, the value of which is not more than los. per acre per 

 annum for agriculture or pasturage, will prove more profitable 

 in growing timber, the demand for which is constantly increasing, 

 while the supplies are diminishing.
