THE PROPAGATION OP ROSES 



enjoy trying to introduce a new variety of his own 

 breeding. 



Ordinarily to hybridize roses properly one must 

 have a greenhouse and it is astonishing what results 

 may be obtained in a very small one. 



In exceptionally dry climates the work may be 

 carried on successfully out-of-doors. 



Books on this subject which are interesting and 

 practical are: 



"The American Rose Annual." 



"Plant Breeding," L. H. Bailey. 



"Plant Breeding, Experiments of Nillson and Bur- 

 bank," De Vries. 



"Plant Life and Evolution," Campbell. 



"New Creations in Plant Life," Harwood. 



"Fundamentals of Plant Breeding," Coulter. 



In Chapter X will be found a few hints on hybridi- 

 zation.
