* Tiiis sum represents the averase nett income per acre which will bn earned upon the average 

 accumulf-Ued capital when once the forest is in proper working rotation, i.e., when it is normally stocked 

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

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

IN VALUE. 



On a 

 11O-year 



rotation. 



The most profitable rotation 



(according to the yields and prices indicated) 



Is one of 11O years, if interest is reckoned at 3J per cent, 

 or ,, 7O at 4 per cent. 



Prices of Timber (standing). 



t 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. 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 3s. 9d. and one of minus 3s. lid. 

 on a 130-year rotation represents, at 8J per cent, interest, an additional loss of 20 per 

 acre. The total loss of 8s. lid. is equal to a capital loss of 441 per acre.
