* This sum represents the average nett income per acre which will be earned upon the average 

 !",l.f.d capital when once the forest is in proper working rotation, i.e., when it is normally stocked 

 with crops of all ages from one year old up to maturity. The cost of replanting is estimated at 5 per 

 acre, ami it is assumed that the land is allowed to lie fallow for one year.

On a 

 13O-year 



rotation. 



The most profitable rotation 



(according to the yields and prices indicated) 

 Is one of 8O years, if interest is reckoned at 3J or 4 per cent. 



Prices of Timber (standing). 



J These prices are equivalent to the following scale of prices : 



Timber 12 in. q.g. and over at Is. 9d. per cub. foot. 

 6 in. q.g. and under 12 in. at lOd. per cub. foot. 

 ,, below 6 in. q.g. at 3d. per cub. foot. 



It is presumed that the trees are felled in winter, and no allowance has been 

 made for the sale of bark. 



Note The difference between a rental of minus 4s. 9d. and one of minus 5s. Id. on 

 a 130-year rotation represents, at 8i per cent, interest, an additional loss of 41 per 

 acre. The total loss of 6s. Id. is equal to a capital loss of 626 per acre.
