horticulture is the time required to test 

 a new variety originated from seed, and 

 that any method which shortens the 

 time required to make such tests must 

 appeal to everyone, whether an origin- 

 ator or a tester of new varieties, as of 

 the greatest value. 



Mr. Oliver writes: "It was discovered 

 by the writer that a large number of 

 hard wooded shrubs and trees are capa- 

 ble of very rapid increase when propa- 

 gated by processes which may be 

 termed the seedling-inarch and nurse- 

 plant methods. 



"These methods are inexpensive and, 

 owing to their simplicity, may be used 

 by persons without previous experience 

 in the propagation of plants. By these 

 methods the ever-increasing number of 

 plant breeders will be able to save 

 much time in determining the value of 

 hard wooded plants raised by means 

 of hybridization. They can be used in 

 manipulating seedlings of rare trees and 

 shrubs intended for crossing, so that

 well established in 

 pots by potting them 

 in March. It is still 

 better to pot them a 

 year in advance.
