No. J. Croivn graft by inlaying. — Figure 5 represents the stock 

 prepared for this form of graft. The stock is cut as for cleft graft- 

 ing. In place of splitting the stub, two V-shaped grooves are made 



on opposite sides of it. These grooves are 

 made by means of an instrument especial- 

 ly designed for the purpose. It is shown 

 in fig. 6. The tip cuts out the triangular 

 part as shown in the illustration. In the 

 blade itself is a part which is bent at the 

 same angles as the parts forming the tip. 

 This indented portion of the blade is used 

 for cutting away the end of the cion, and 

 with very little practice an almost perfect 

 fit of the two parts can be made. The 

 two cions are then placed upon the stock 

 and are firmh' tied there. The tying 

 material should be of such a nature that it 

 will deca}^ before there is any danger of 

 strangling the cions. Raphia does very 

 I have also used No. 18 knitting cotton, 

 soaked in boiling grafting wax, with entire satisfaction. The 

 ligatures should be made as tight as possible. 



Although this method of grafting is not so commonly used as 

 others, it still possesses some decided advantages. It is a much 

 simpler and more satisfactory method than cleft grafting in very 

 curly wood. The tying is a slow process, and for straight-grained 

 wood the cleft

 is also open 

 to the object-

 ing the shoots to be staked or tied to some support, for the wind is 

 apt to break the point of union more easily than with other 

 methods. A good union admits of a very strong growth, and 

 if the above precautions are kept in mind the vines will equal 

 those produced by either of the preceding methods.
