orange stock for citrus trees wliicli are apt to be attacked by gummosis, and 

 also to the practice of inserting Sour orange buds beneath the wounds of trees 

 already attacketl by gummosis. These buds, which are allowed to grow for 

 2 or 3 years, appear to arrest the disease and the wound becomes callused over. 



When the buds become too rank in growth they are removed and the opera- 

 tion Is repeated by starting 1 or 2 new Sour orange buds below the wound. 

 This method is of special value for renewing old lemon trees.
