regardless of origin, whether from seed blown in, planted, or shelter- 

 --ood. The resemblance follows from the 20-3$ year on, there being then 

 no points of difference, either advantageous or disadvantageous. 



4) Two-storied form starts as even-aged forest, later 

 underplanted, either naturally or nrtif icially . When its real character" 

 develops, this form is very distinct, not at all like the even-aged stan 

 The reserve tree form is merely an extreme form of the two-storied fores 

 in v:hich the upper story is thinned to the point where there is merely a 

 lot of ecattcrin, d treen. They are' often left for seed trees and are 

 harvested vdth the next generntion. 



5) All-??.e or many-aged form is always distinct; it is the 

 only form that is continuous in its physiography and development. 



The all- old form is conspicuous in wild- woods, and forms a large 

 -r-r cent of the merchantable timber. It hn.s not been adopted in Silvi- 

 culture, because it requires too long a rotation. 



b.ln later ye?irs fiil vi cultural authors classified forms. Gayei 

 i a not? ; le example. 



Of the older authors, Lorey did not classify f orms; he classified 

 simply the methods used to get these forms of forests.
