POSTSCRIPT. 



In submitting this volume, the writer should feel particularly 

 beholden to recipients, if they would furnish him with such 

 additional reliable notes, as might suggest themselves during the 

 use of this work, and as would be deserving of insertion in a book 

 like this within its own scope. This request is made without 

 reluctance, because the author does not derive any monetary profit 

 from this volume, and also because the fulfilment of the wishes now 

 expressed can involve nowhere much trouble and expense. More- 

 over, in here treating prominently utilitarian plants of our whole 

 planet, except those of the hottest zone, it needs much aid of locally 

 experienced collaborators in all different regions, if such a publication 

 is to be brought to perfection and to be maintained in such. While 

 approaching the eighth decade of his life, the author cannot hope to 

 see many more editions of this work, brought up to the newest 

 standard, through the press himself ; but as he may perhaps still be 

 able to publish one more edition before passing away, he is now 

 particularly eager, that the next issue should by some special efforts 

 be rendered as complete, as this within the knowledge of the present 

 days can be accomplished. Such help furthermore would really be 

 a recompense only from those who, in using this book, derived some 

 practical rural benefit or instructive advantages from its pages.
