falling oft in growth, i.e. to yield less of a 

 return on the capital represented by soil plus 

 growing stock than has until now been the 

 case, then obviously it will be good business 

 to clear it off and utilise the land for the pro- 

 duction of a younger and more vigorous crop. 



It would of course be extremely inconvenient 

 nay, impossible in view of a regularly sustained 

 annual yield to treat every portion of a large 

 woodland area in this particular manner on its 

 own individual merits, but a general scheme as 

 to rotation of the fall for given kinds of tree- 

 crops in the given local circumstances can con- 

 veniently be arranged and followed. When, 

 these last being duly considered, the kind of 

 crop, the system of management, and the 

 rotation of the fall have been fixed on, the 

 capital in wood must, in order to provide a 

 regularly sustained annual yield, be adjusted 

 and distributed in such a manner that each 

 successive year's fall shall consist of an equal 

 or, rather, an equally productive area, while 

 the capital in growing stock must consist of 

 such number of equally productive areas as 

 there are years in the period of rotation from
