These figures are given on the assumption that all forest 
operations are conducted in a truly economic manner, Dr 
Schlich further points out that if timber is grown on a short 
rotation for fencing or pit-props, the yield, according to the 
price of land, might be from g per cent. to slightly over 3 per 
cent. in the case of larch, and in the case of Scots pine and 
spruce, from over 54 per cent. to 2} per cent.; and he thinks that 
land capable of growing Scots pine and spruce is not likely to 
cost £9 an acre, probably not more than £4 to £6, and in 
that event the return might be from 4 per cent. to 5 per cent. 
Mr A. C. Forbes says the average net return per acre per annum 
from a properly selected area may be put at from tos. to I5s., 
allowing for non-productive ground, and calculating on the basis 
of present prices for timber, labour, and material. If an aver- 
age total return of £125 per acre can be obtained from land not 
worth more than 5s. per acre for agricultural purposes, no diffi- 
culty should be experienced in securing the average net annual 
yield of ros, to 15s. per acre, which has been stated as possible 
from a well managed area. Mr Lewis Miller says that in his 
experience a return of £1 per acre should be obtained from land 
under timber which is only worth from 1s. to 2s. per acre for 
sheep or cattle pasture.
