 character for Yin-kuo, i. e. Silver-nut. It was found by Kaempfer in Japan and 

 was introduced into cultivation in Europe at the Botanic Garden at Utrecht about 

 1730. It was introduced into this country in 1784 by William Hamilton, who 

 planted it in his garden at Woodlawn, near Philadelphia. It grows well and is per- 

 fectly hardy in New England. In Washington it is used as a street tree.
