CUTTING is a part of a plant capa- 

 ble of emitting roots, and of becoming 

 an individual similar to its parent. The 

 circumstances requisite to effect this 



in the heaths, the orange, and cera- 

 tonia. 



A rooted cutting is not a new plant, 

 it is only an extension of the parent, 

 gifted with precisely the same habits, 

 and delighting most in exactly the same 

 degree of heat, light and moisture, and 

 in the same food. 



A cutting produces roots, either from 

 a bud or eye, or from a callus resem- 



of moisture.
