XXVII. Upon the Propagation of Varieties of the Walnut 

 Tree, by budding. By Thomas Andrew Knight, Esq.

The ill success of many attempts to propagate the Wal- 

 nut Tree by grafts, or buds, led me, in a former communi- 

 cation, to discourage all attempts to increase it, except by 

 seeds, or by grafting by approach. I nevertheless continued, 

 annually, to make a few experiments, with the hope of 

 discovering a method of budding, which would prove suc- 

 cessful in the culture of varieties of this fruit, and of others 

 of equally difficult propagation ; and I have found, in ulti- 

 mate success, the usual reward of patient perseverance. 



The advantages of propagating varieties of the Walnut- 

 Tree, by budding, will, I think, be found considerable, 

 provided the buds be taken from young, or even middle 

 aged healthy trees : for, exclusive of the advantage of obtain- 

 ing fruit from very young trees, the planter will be enabled 

 to select not only such varieties as afford the best fruit, but 

 also such as endure best, as timber trees, the vicissitudes of 

 our climate. In this respect some degree of difference is 

 almost always observable in the constitution of each indivi- 

 dual seedling tree ; and this is invariably transferred with 

 the graft or bud. 



The Walnut, it is true, as a fruit, contains but little nutri-
