H hi/ Grafting. 219 



393. Side-grafting is chiefly practiced with plants in 

 leaf, under glass. The cion is joined at the side of the 

 stock, which is usually not cut off, and is secured in 

 place by wrapping tightly with bast * or raffia. Three 

 slightly different methods are in use. 



a A shaving of bark, thick enough to reach into the 

 cambium layer, is removed from the side of the stock by 

 making a long vertical cut and a short transverse cut at 

 the base, and to this cut surface the cion is carefully 

 fitted, and bound with raffia. This method is called 

 veneer-grafting. 



b A sloping cut is made rather deeply into the sap- 

 wood of the stock, into which the cion, after being tapered 

 at its base to the form of a wedge, is in- 

 serted (Fig. 118), and the parts are then 

 held closely together by binding with raffia. 

 This method is generally employed in herb- 

 aceous grafting, as with the potato, tomato 

 etc. It is also much used in grafting ever- 

 greens under glass, and occasionally in graft- 

 ing outdoor nursery trees. In the latter 

 case, a coating of grafting wax is usually 

 graft inserted, substituted for the tying. 



r tying. c ^ short, transverse incision is made, 

 and immediately below this, a somewhat longer, vertical 

 cut the two cuts, which are just deep enough to reach 

 through the bark, forming a T (Fig. 121). The cion is 

 then cut off with a long, sloping cut, and the point in- 

 serted, the cut surface inward, beneath the two lips of 



* Bast is the fibrous inner bark of the bass-wood or linden tree (Tilia). 

 It was formerly much used for tying grafts and buds, but has been largely 

 supplanted by raffia, which comes from a palm of the genus Raphia.
