the least. One will then have five main branches with a 

 few laterals on each. It is customary to remove all these 

 laterals. [But "custom" should be based on principle. 

 Each case should, therefore, be decided by the pruner's 

 best judgment. Cut or leave the laterals as judgment 

 may dictate.] By the middle of June, the young tree 

 should have made sufficient growth to allow for summer 

 pruning. Each branch should be pinched back so as to 

 leave it from 8 to 15 inches long, cutting according to 

 vigor, always suppressing the stronger. 



171. In the third spring each of the original five main 

 frame limbs will have from one to a dozen lateral or addi- 

 tional branches. It is 

 customary to remove 

 all but one from each 

 main branch, so that 

 when the tree is pruned 

 there will be ten 

 branches on the tree 

 where there were five 

 before. A great deal of 

 care should be used in 

 selecting these new 

 branches. The two 

 branches on each frame 

 limb should be spaced 

 as far apart as possible. 

 Of course avoid tlu- 

 choosing of laterals 

 which will tend to grow 

 in toward the center of 

 the tree. Then avoid 

 cutting these two lat- 

 erals equally. Choose
