AHBOKETUM ET FRUT1CETUM BKITANN ICU M. 



For small gardens and diminutive arboretums, this tree may 

 serve very well to exemplify the ,/uglandaceae. Care should 

 be taken to train it to a single stem, and not to plant it in 

 soil so rich and moist as to prevent it from ripening its wood. 

 Perhaps, also, something might be gained in point of hardi- 

 ness bv grafting it upon the common walnut; either on the 

 collar "of the stock, in order to form dwarf trees or bushes ; 

 or standard high, in order to form trees that would from the 

 first have clear straight stems, and as they would ripen their 

 wood better, in consequence of growing slower than the 

 low trees or bushes, so they would perhaps show blossoms 

 and ripen fruit.
