THE TREATMENT OF GAME PRESERVES. 51 



If the calculations with the other per cents, are carried out, 

 we obtain the following :

These values are now plotted with the per cents, as 

 abscissae and the soil values as ordinates, and a curve drawn 

 through them, when the diagram on page 50 is obtained. 



From this diagram the per cents, yielded under different 

 soil values were read off and entered in the above table for 

 larch. The per cents, for other species were ascertained in 

 the same way. 



5. The Treatment of Game Preserves. 



In the previous pages I have dealt chiefly with the afforesta- 

 tion of additional areas, and, I trust, shown that a fair interest 

 on the invested capital may safely be expected. I cannot close 

 this essay without offering a few remarks on the subject of 

 improving the returns from some of the existing woodlands. 

 As already stated, the management of these woods is subject 

 to special demands on the part of the proprietor, which 

 frequently reduce the income ; nevertheless, I believe that 

 the latter can be considerably increased, if the management 

 is more systematised in the manner now to be indicated. 



British woods consisting of broad-leaved species are used as 

 game preserves, especially for the rearing of pheasants, and 

 the latter object is, in the majority of cases, paramount. On 

 most estates the gamekeeper's duties are entirely separate from 

 those of the woodman, and in only too many cases the two men 

 prosecute different objects. 



If antagonism has hitherto existed between the two officials 

 of an estate, it is, at any rate in many cases, just as much the
