Cleft Grafting 1 . This mode of grafting derives its 

 name from the mode in which it is performed, viz., a cleft is 

 made in the stock with a chisel at a, keeping the cleft open 

 till the scion is inserted. The section of the scion should 

 be an oval c, and not a triangle b ; care being always taken 

 to make the barks meet. Tie and cover with clay or wax. 

 Cleft grafting is not recommended. 



Triangular Notch Grafting is sometimes adopted 

 instead of cleft grafting. The illustration will explain itself. 



Crown or Rind Grafting. This mode of grafting 

 is preferable to cleft grafting, for the reason that the wood 

 of the stock is not interfered with. This form of grafting is 

 adopted with old trees. The lower end of the scion is cut 

 sloping, as in whip grafting. The head of the stock is cut 

 over horizontally, and a slit a is made just through the inner 

 bark. A piece of wood or bone, resembling the thinned end 

 of the scion, is introduced at the top of the slit, and pushed 

 gently down in order to raise the bark sufficient to introduce 

 the thinned end of the scion without being bruised. The 

 edges of the bark are then brought close to the scion, and 

 the whole is bound with matting and clay. Other scions 

 may be inserted in like manner at b and c. 



Side Grafting is a modification of whip grafting, and 

 is performed in the same manner, except that the stem or 

 branch, instead of being cut completely off, is notched to a 

 greater or less depth, as at b. It is also useful for supplying 

 a branch where required, as at a. In supplying a branch, 

 as at a, the scion must be placed with a head pointing out- 

 wards, and the shoot proceeding from it trained in a hori- 

 zontal direction towards e. When required to substitute 

 another branch, a notch is made, as at <, and a slice is taken 

 off between the notch and the stem, as at c. The graft is 

 placed there. As the shoot grows it must be trained hori- 

 zontally, and spurs, as at d, cut away. When the new branch 

 has made a considerable growth, the original branch may be 

 clean cut away at b. 



Herbaceous Grafting. As its name implies, is 

 applied to herbaceous plants, when in full growth. Make 

 an oblique incision, , as close as possible to the base of the
