PREFACE TO THE SECOND EDITION. 



Aftee a lapse of fifteen years the author has been called 

 upon to prepare for the press a Second Edition of this work. 

 In obeying the call, he gladly avails himself of the only public 

 opportunity that he can have for thanking his foreign editors 

 for the honour they have done him by translating the book into 

 German,* Dutch,t and Eussian.I , 



He has always felt that the naked principles laid down in the 

 First Edition were less interesting than they would have been 

 if they had received more extensive illustration from examples 

 and frequent reference to practical operations. He has now, 

 therefore, greatly extended the matter, and endeavoured, when- 

 ever it appeared necessary, to support the doctrines of physiology 

 by an appeal to facts which are or should be familiar to culti- 

 vators. In doing this he has to express his sincere gratitude 

 to the numerous intelligent contributors to the Gardeners' 

 Chronicle, who during more than fourteen years have honoured
