 procured as a stock, ' choose a scion of similar

 direction as for the common whip graft. Then, 

 without taking off the head of the stock, cut from the 

 clearest part of its stem an equal splice, as smoothly 

 as possible, so as to be fit to receive the scion : let 

 neither stock nor scion be tongue d, but apply the 

 scion to the stock in a neat manner, so that their 

 barks on both edges and below may join, and then 

 tie them in a firm manner with matting, and clay 

 them as in grafting. Then cover with a tall glass or 

 receiver (technically a cap) , and plunge in a mode-

 as cuttings.' In six weeks the scion will have begun 

 to grow, and the head of the stock may be cut neatly 

 off, and the clay and ties removed by degrees.

 plants, but it is not in very general use. There are

 others were also added. Those amateur cultivators 

 who wish to acquire the practice of it, will learn more 

 from observing an expert gardener perform the
