200. Care of Buds and Grafts. There are many special 

 ways of budding and grafting. All depend on the prop- 

 erty of callus-tissue of two different plants to form a close 

 living union. In making the cuts, nothing but the 

 sharpest of knives should be used. Dull knives produce 

 such mutilation that the cambium does not grow out 

 and form the callus-tissue promptly, and, as a result, 

 the graft or bud fails "to take." The dormant buds 

 on the stock are inclined to form vigorous-growing 

 sprouts, but should be rubbed off as explained in ^ 197. 



201. Transplanting Nursery Trees. Nursery trees, 

 whether propagated from seeds, cuttings, buds, or 

 grafts, are removed from the nursery rows and trans-
