(e) diseased trees of all sorts ; 

 (/) old seed-bearers. 



II. Dominated trees. This class includes all trees which do 

 not form part of the uppermost leaf-canopy. These are : 



(3) Dominated trees, which, however, are not yet actually 



under the shade of their neighbours and the leading 

 shoots of which are, therefore, still more or less free. 



(4) Suppressed trees, that is, trees standing under the shade 



of their neighbours and with their leading shoots 



dominated. 



(Classes (3) and (4) then may, on occasions, be useful for 

 protecting the soil or helping to clean the boles of their more 

 vigorous neighbours.) 



(5) Dead and dying trees which are of no use either for soil 



protection or for cleaning the boles of neighbouring 

 trees. Small and very badly suppressed trees may 

 also be included in class (5). 



N. B. Under class (2) some of the trees referred to under (a), 

 {c), (d) and (e) may also occur in the dominated section. There 

 is, however, no need to designate them separately under any class 

 except class (2) as it includes (3), (4) and (5) which usually 

 disappear first in the thinnings. 



Thinnings are mostly concerned with the removal of 



(a) dead and dying trees ; 



(b) trees which are being left behind in the struggle for 



existence ; 



(c) diseased trees ; 



(d) trees with poorly developed boles or crowns ; 



(e) misshapen trees. 



(/) trees with good crown and boles which are harming more 



valuable trees. 



Thinning may thus include trees falling under classes (2) 

 to (5) either wholly or partly and, more rarely, some trees of 

 class (1).
