BARK GRAFTING 103 



to two inches in size. The top of the branch is not cut 

 off, but is bent over and a downward sloping cut made into 

 the side where the new limb is to be placed. The cion is 

 then cut with a long sloping face as shown in Fig. 50. This 

 is fitted into the stock by bending it over, care being taken 

 to get the cambium layers to fit closely along one side. 

 The union is then tied up and carefully waxed over. It 

 is also possible to renew the top of a tree by this method. 

 The graft is placed on the smaller branches and as soon 

 as growth starts the part a*bove is cut off close to the 

 union. 



Bark Grafting. This is a method of top-working trees 

 which may be used after growth has started in the spring. 

 All the other grafting operations should be done while the 

 trees are still dormant. If this is impossible the method 

 of bark grafting may be used. In this process the important 

 thing is to keep the cions from starting. They may be 

 collected in the usual way and placed in cold storage, or 

 if this is not available, bury them in the sawdust on top of 

 the ice in an icehouse. By these methods the cions may be 

 kept dormant from four to six weeks beyond the normal 

 growing season. 



To bark graft, the stock is cut in the same manner as 

 for cleft work. The bark is then cut down for an inch 

 and a half and the corners carefully loosened from the 

 wood. The cion is cut with a long slope on one side only 

 (see Fig. 51). This is then inserted in the stock between 

 the loosened bark and the wood, placing the cut surface of 

 the cion next to the wood. It is tied up with raffia and 

 waxed over as for the other grafts. The two unite quickly
