258 OUR FORESTS AND WOODLANDS 
In each system of management there is there- 
fore a certain amount of capital which can be 
invested with profit in the growing stock, and 
which must in fact be invested in order to 
obtain the best returns from the land. And it 
is one of the main objects of Forestry to indicate 
theoretically, as well as to arrange practically, 
how the necessary capital in wood can best be 
adjusted and distributed over the woodland area, 
in order to produce the most advantageous re- 
turns in the shape of a regular yield sustained 
annually. While the market available for 
woodland produce must of course be one of 
the chief factors in determining the kinds of 
crops to be grown and the system of manage- 
ment to be accorded to them, yet the soil, the 
situation, and the local climate generally are 
all matters of importance for financial success ; 
and these have frequently in the past received 
less attention than they require. Hence the result 
has often been that the growth of the crops 
has been unsuccessful. Annticipations not having 
been realised, many landowners have thought 
that Forestry does not pay in Britain. But this 
is due to the bad effects of these investments,
