 mented with the tree in the Philippines, finds that it can be 

 shield-budded in the same manner as the avocado. He says:

 cut the buds about an inch and a half long; age of stock at 

 point of insertion of bud unimportant." By utilizing this 

 method of propagation it will be possible to perpetuate choice 

 varieties which originate as chance seedlings.
