PROPAGATION. 45 



preparing the graft from the young and tender wood of 

 the species to be propagated. The well-known mode of 

 cleft grafting is then employed, and the plant shaded from 

 the rays of the sun and heavy rains until the two are 

 firmly united. Figure 7, from Dubreuil's Arboriculture, 

 illustrates the operation. The wood, both in the stock 

 and graft, should have acquired a little toughness before 

 using, but should not be fully ripened. 



We have seen excellent success in grafting Arbor Yi- 

 ta3S in the open air, by the common method of cleft graft- 

 ing. The stock in this instance is headed down close to 

 the ground ; and after performing the operation, the earth 

 is drawn closely around, leaving the upper portion of the 

 graft only above the surface. An occasional wetting will 

 be sufficient to start it into action. Other methods are 

 practised by gardeners, but differ only in minor details 

 from these described.
