 under a tree growing by the grave of Confucius. 

 He brought them to America and gave them to 

 Dana, who planted a number of the acorns on the 

 grounds of his home. One of the acorns was 

 presented to Mr. William R. Smith by Mr. Falconer, 

 a horticulturist, who was at that time superinten- 

 dent of Mr. Dana's extensive grounds at Glen 

 Cove, Long Island. Smith had the acorn planted 

 south of the greenhouses near Maryland Avenue 

 and Second Streets, Southwest.
