PLANT CULTURE 



Preface to Fourth Edition 



The undertaking of this fourth edition was assumed with ex- 

 treme reluctance by the writer because of the eminence of Geo. W. 

 Oliver in the field of plant culture and propagation. 



In this practically rewritten and enlarged volume much addi- 

 tional cultural matter and many new subjects have been incorpor- 

 ated, every endeavor having been made with a view of presenting 

 an epitome especially of those plants which figure in present day 

 ciiltivation. 



Some progress has been made in the twenty years since the first 

 edition was printed; many flowers have gained or waned in popu- 

 larity. Every effort has been made to preserve the practical style 

 of Mr. Oliver which has served in the past as authority for thousands 

 of gardeners. 



The writer is indebted to Messrs. Carl E. Haas and Sylvester 

 Pautler, students, who have assisted with several chapters. Baile}-'s 

 Standard Cyclopedia of Horticulture has been used as authority 

 for nomenclature.
