 tree is said to attain a height of 50 or 60 feet in Japan. As seen in 

 this country it is a handsome tree, dwarfish and compact in habit,

 it can grow. 



The immunity of the Japanese chestnut, together with the fact 

 that it was first introduced and cultivated on Long Island and in the 

 very locality from which the disease appears to have spread, suggests 

 the interesting hypothesis that the disease was introduced from 

 Japan. So far, however, no facts have been adduced to substantiate 

 this view.
