 must otherwise be much better in order to justify 

 the undertaking.

 considerable portion of this pruning were under- 

 taken in June or July. In any case it will be best 

 to carry out the work in two or three installments. 

 At the first pruning only the largest broken limbs 

 are to be removed, along with the wood which is 

 actually dead. After them there may be taken out
