face of the longitudinal cut is made even to correspond "with 

 the surface of the stock where the bark is raised. The bark, it 

 may be observed, is raised on one side only. In order to pre- 

 serve the graft from the effects of heat and cold, he covers the 

 cuts with clay, and then surrounds the graft with a band of 

 bark 4 inches wide. In this way he operates on stocks thirty 

 years old, and vouches for the success of the method. 



Treatment after Crown-Grafting. 

 This is limited to — 1. Keeping an eye on the bandage 

 loosening it if it becomes too tight, and renewing it if the 

 cohesion is not perfect. 2. Tying up the young shoots on 

 rods or on a stake taller than the graft. 3. Eemoving any 

 shoots or buds that may appear on the stock. 



Group III. — Grafting de Precision. 

 Grafting de precision, or precise grafting, implies that the 

 stock and scion are so accurately prepared and fitted to each 

 other, that when they are put together they will coincide 

 perfectly, without using any force, and without leaving any 

 vacuum. The rigorous exactness which the operation demands, 

 has led to the invention of special implements, such as the 

 combined grafting knife and the metro-greffe. Spring is the 

 proper season for precise grafting. It succeeds also in 

 summer, if care is taken to select the woody part of young 

 branches for scions, to shade them, and keep them from, 

 getting dried. Towards the end of summer, when the flow 

 of the sap is diminishing, this method may also be employed, 

 observing that the sap should be sufficiently active to produce 

 immediate cohesion, but not so active as to cause an autumnal 

 development of the buds. Experience accustoms one to 

 perceive the moment when the sap begins to thicken, when 

 the functions of the leaves are at an end. Under this new
