EXERCISE XXXVII 



THE STUDY OF SIDE GRAFTING 



Material. Stocks of the apple or pear, one inch in diameter 



and twelve inches in length, scions from the same kind of trees. 

 Apparatus. Sharp, narrow chisel and sharp knife. 

 Side grafting is the method of grafting by inserting the scion 



into the stock without the cutting off of the stock (Fig. 35). It 



is often used to place a limb in a 

 certain region where one is lack- 

 ing, or for the grafting of some 

 difficult subject, such as the mul- 

 berry or some of the beeches. The 

 scion is placed in the side of the 

 stock, set into an oblique incision 

 made for the purpose. This cut 

 can best be made by a thin-bladed 

 chisel with a bent shank ; how- 

 ever, any ordinary knife or chisel 

 may be used. The angle at which 

 the scion is placed is usually about 

 30 degrees. The incision should 

 be made about an inch deep, and 

 the scion should be cut wedge- 

 shaped. As in bark grafting, the 



length of the wedge-shaped cut should correspond to the depth 



of the incision made in the stock. 



1. Secure stocks about one inch in diameter and ordinary 

 scions containing from two to four buds. Practice by making 

 a number of these grafts. 



Make a natural-size drawing of the stock, four inches in length, 

 showing the chisel or the knife in position. 



2. Make a drawing the same size as in 1, showing the scion 

 in position. How long is the wedge-shaped cut on the scion ? 

 Does the entire wedge of the scion fit into the incision made in 

 the stock ? Make a natural-size drawing of the scion. Discuss.
