A NATURAL TREE GRAFT 



'T'HE essential thing in grafting is that the growing ceUs, 

 or cambium, of stock and scion shaU meet in order that 

 further growth may form a firm union between the two. It oc- 

 casionally happens in nature that one branch rubbing over 

 another exposes their respective cambiums and then luider fav- 

 orable circumstances a similar union may result. The accom- 

 panying illustration shows an instance of this kind that has 

 occurred among the branches of an ancient live oak {Oucrcus 

 agri folia) on the Pacific Coast. The tree is growing on the 

 Providencia Ranch near the Los Angeles river a short distance 

 from Hollywood, and the photograph was kindly sent by Mr. 

 Fred E. Burlew.
