148 LANDSCAPE GARDENING. 



Spanish and Japanese varieties is much larger but not of 

 as good quality as that of the American, and the trees are 

 less vigorous. Improved varieties of our native chestnut 

 with fruit of large size are now offered and established trees 

 are sometimes grafted with them with success. The smaller 

 and more vigorous the stock the more certain the success in 

 grafting.
