GRAFTING AND BUDDING.

pared in all respects as if for a cutting. It is cut clean at L 

 and K, the leaves at the base are cut down to the stalk, and 

 those at the top through the middle of the blade. The scion 

 (I) is cut equally on both sides in a sloping direction, as if for 

 side-grafting in the alburnum. It is then inserted hi a cleft in 

 the top of the stock, and the graft is bandaged with a pliant 

 fastening. The subject thus grafted is then potted and placed 

 under a cloche in the propagating house. Before long, roots 

 will be formed simultaneously by the stock (at L) and by the 

 scion (at M), from which the graft will derive an increased 

 amount of vigour. After at least a year's growth, the upper 

 part of the stock between K and the graft is cut away ; but it 

 is better to retain the rooted part of the stock, instead of 

 severing it from the graft. The natural roots of the latter, 

 being nearer the surface of the soil, always eventually starve 

 out and supersede the roots beneath them, so that they never 

 spread. 



Root-Grafting. 



Many plants which are difficult of propagation may be mul- 

 tiplied by grafting a branch on a portion of root either their 

 own or that of another plant ; whence arise two sub -divi- 

 sions : — 



1. Grafting a Plant on its oiun Boots. 

 It is probable that woody species, for the grafting of which 

 no allied species can be found, can be propagated by grafting 

 their branches on their own roots. Dr. Loiseau, of Mont- 

 martre, who had begun some experiments on this subject, died 

 before completing his investigations. We shall, however, 

 mention some methods which have been admitted into 

 practice. 



Hoot-Grafting by Approach. 

 In 1867, M. Grasidou, gardener to the Botanic Garden at 

 Montpellier, more fortunate than his predecessors, succeeded
