methods. A slice of bark and cambium is cut from both stock and 

 cion, the two brought together so as to fit exactly; they are then 

 firmly tied. After the union is assured the cion is gradually severed 

 from the parent to avoid a too sudden check.

Root grafting is a very simple operation, and is practiced with 

 such plants as Clematis, Rose, Shrubby Paeony, and many other 

 plants. When all other stock fails this may be tried, merely select- 

 ing roots of the same or allied species. The Shrubby Paeonies are 

 grafted on the large tuber-like roots of the herbaceous species. A 

 notch is made in the side of the swollen tuber-like root, the lower 

 part of the cion being made to fit this. 



With Roses and Clematis splice grafting will answer* with 

 Wistarias and Bignonias saddle grafting is preferred. 



In grafting, a very sharp and clean knife should be used, to make 

 a clean cut, so that the surfaces may go closely together. In all 

 cases the bark of both stock and cion should come evenly together, 

 at least on one side, and on both if possible. 



BUDDING differs from grafting in that only a single bud is used 

 on the stock instead of a piece of branch on which there are one or 

 more buds, as in grafting. A near relationship must exist between 

 the plant from which the bud is selected and the plant which is to 

 receive it. The operation is a trifle more delicate than that of
