Tabular statement of fellings.— As a rule the whole of 

 the prescriptions are summed up in a single simple tabular 

 statement containing the following columns : — 



Year or period for which operations are prescribed. 



Area to be taken in hand each year or period. 



Nature of fellings to be made. 



Area or quantity of material to be exploited. 



Bemarks. 



More than this is seldom required, no matter how com- 

 plicated the operations prescribed may be. The area to be 

 taken in hand should, if possible, be shown under the different 

 headings : wooded, blank, unproductive. In the last column 

 but one should be entered either the area, the number of 

 trees, or the volume of material to be felled. 



Eaample. — The following example illustrates the adaptation of such a statement 

 to different classes of operations : —
