much better. For observe the contrast. E represents the 

 same plant A pruned up to a leader by the total removal of 

 its lateral shoots in the usual way. F will 

 show what such a plant may be expected to 

 become at the end of the season, instead of 

 D, which it would have been under the 

 influence of stopping only. 



The same observations will apply to 



cases where a pair of leaders contend with 



each other, as at G. If one of the leaders 



only is broken off and stopped, as at a, 



scarcely any of the energy of the tree will 



Fig. Lxxxv. be destroyed, but the sap will be thrown 



into one of the leaders much more than the other; and 



at the end of the season the plant may be expected to 



resemble H. If, however, instead 

 of being treated thus, G be de- 

 prived of all its laterals, and left 

 by the pruner as at I, the digest- 

 ing powers of 

 the plant will 

 be so com- 

 pletely re- 

 moved that we 

 can hardly 

 expect it to 

 become a;t the 

 end of the first 

 year better 

 than at K — the 

 difference be-

These dia-

the true principles of managing young forest-trees, so far as 



controlling their form is concerned. They are now recognised
