appearance of the wood, and which is very inju- 

 rious. 



17. Square hud-grafting. This is performed by 

 cutting out a square piece of the bark, 

 as at (a), and putting in its place a sim- 

 ilar one of the variety designed to be 

 grafted, and binding so as to exclude 

 the air. 



18. Tubular bud-grafting. When the bark will 

 rise, the end of the shoot to be 

 operated upon is cut off at a place 

 where it is free from all inequali- 

 ties, and the bark stripped down 

 for about an inch, as in figure a. 

 A scion is selected a little larger, 



and its limits marked out with the knife below. 

 After being held in the hand a minute or two, the 

 bark will expand and the tube come off, when it 

 should be placed upon the bare wood, and the bark 

 stripped down until it fits tightly. 



19. Greffe en ecusson (budding). This has the 

 advantage that, if it does not succeed, the subject has 

 not been injured by the operation, and another bud 

 can be introduced. The proper season is when the 

 sap is flowing, and the bark will rise easily. All 

 shoots which would interfere with the young bud are 

 first cut away. Detaching the bud is done in two 

 ways. Some species of plants have tender wood and 

 bark, and it is necessary that the wood be removed
