 to take root, and this method of propagation should not be

 largely dependent upon the proper selection of the budding 

 wood. Citrus buds should be cut from round plump wood 

 taken from fruiting branches. Suitable wood of this char- 

 acter is difficult to find on the orange but it is more plentiful 

 on the lemon. The orange tree from which the buds are to be 

 selected must be prepared a year in advance. The prepara- 

 tion of the tree consists in systematically pruning the
