Many big trees are in above cited localities where they are un- 

 doubtedly wild. We counted the number of the annual rings of several 

 cut down trees and could ascertain that they are more than three 

 hundred years old. Their timber is good to make tools and furnitures. 



This pear is an allied species of Pyrus ussuriensis ; but differs from 

 it by having more tapering leaves, rufo-ferrugineous buds, white pilose 

 young leaves and greenish fruits. A form of this pear well agrees with a 

 garden form called Sodorihime ~lx. : M &PE which is an old type of green 

 sand-pears cultivated in the north-eastern part of Hondo. The natives 

 gather the fruits and sell them filling in strawbags. Pomologist raises 

 the stocks from their seeds. This is one of the wild pears (Ishi-nashi) 

 of Japan and make a group of green pears (Ao-nashi) with the next 

 species and some others.
