THE TREATMENT OF GAME PRESERVES. 



Ul 



grow. Under any circumstances, the ages of the standards 

 must be multiples of the rotation of the underwood whenever 

 cutting comes round ; that is to say, in our example coupe 

 No. 1 would contain standards aged 20, 40, 60, 80, 100 . . . 

 years old, of which the youngest form part of the underwood, 

 until cutting has actually taken place. 



The number of standards in the several age-classes must 

 form a falling series, in other words, there must be more 

 standards in the twenty years old class than in the forty 

 years class, and so on to the oldest class which would contain 

 only a few trees per acre. It is, of course, out of the question 

 to work up exactly to the theoretically determined number 

 in each class. Hence such figures can only serve as a general 

 guide. By way of illustration , the following example will show 

 the numbers before and after cutting and the difference, 

 representing the number of trees removed at each cutting, 

 assuming that the oldest trees shall reach the age of 100 

 years. 



Number of Standards immediately before Cutting. 



Number of Stantjards immediately after Cutting.
