trees ; it is also used 



in crowji-grafting where the st(»ck exceeds fnif 

 inch in diameter. 



The scion shonhl be at least fonr inches 

 long. Its lower end should be cut wedge- 

 shape and slightly thicker on one side 

 than on the other (Fig. 20 [1]). The 

 stock is cut off s(iiiarely with a fine- 

 toothed saw. With a grafting iron it is 

 split (Fig. 20 [2]), an<l with the point 

 of the gTafting iron the cleft is held open 

 until the scion is

inserted. When 

 large stocks are 

 used it is best to 

 insert two scions 

 — one on each 

 side of the stock. 

 In inserting the 

 scion the cam- 

 binm layer on 

 the thicker side of the wedge should be 

 in contact with the cambinm layer of the 

 stock (Fig. 20 [3]). 



When the point of the grafting iron is 

 removed the cleft closes np and holds the 

 scion in place. It is then firm-ly wrapped 

 with grafting cord or cloth ; the entire 

 union is then covered with oraftino- wax. 

 It is not necessary to wrap the union if 

 the pressure of the stock is sufficient to 

 hold the scion in place. 



Saddle-grafting. — ■ Saddle-grafting is 

 practiced with a few plants. It consists 

 in cutting the upper end of the stock 

 wedge-shape (Fig. 21 [1]). The lower 

 end of the scion is cut off squarely and 

 a cleft made into this lower end (Fig 

 21 [2]). The scion is then pushed onto 

 the stock so that the wedge of the stock fits 

 into the cleft of the scion (Fig. 21 [3]). 

 The cambium layers should be in contact. 

 The union is wrapped with grafting cord, 

 and covered with gTafting wax. 



Side-grafting. — Side-gTafting is a very 

 simple method of grafting. It is some- 

 times used with the plum and a few other
