PREFACE XV 



XII., which has been thoroughly revised ; and to Mr. 

 J. Wright of that office I am very much beholden 

 for kind counsel and advice. For revised reproduc- 

 tions of papers of mine which have appeared in the 

 Journal of the Boyal Horticultural Society and in 

 The Bosarian's Year Book, I have to thank the 

 Eev. W. Wilks, Sec. E.H.S., and the Eev. H. H. 

 D'Ombrain, Hon. Sec. of the National Eose Society. 



My best thanks are due to my neighbour, the Eev. 

 J. H. Hocking, Eector of Copdock, for considerable 

 trouble in the identification of Insects, and to Mr. 

 E. B. Lindsell, of Bearton, Hitchin, for advice and 

 encouragement. Messrs. A. Hill Gray, J. Bateman, 

 Ismay Fisher, and the Eev. F. E. Burnside have also 

 kindly helped me with photographs, or in other 

 ways. 



Mr. William Paul's large work. The Bose Garden, 

 has naturally been consulted and proved of much 

 value, especially in Chapter II., and a further com- 

 parison of ideas and methods has been made with 

 the contents of most other Eose-books ; but my own 

 experience, which is considerable, has been through- 

 out my principal reliance, and where my practice is 

 at variance with the general use, reasons have been 

 given for the procedure recommended.
