ADVERTISEMENT TO THE THIRD EDITION. 



The rapid sale of the two former Editions of the Green- 

 house Companion is at once evidence of the growing in- 

 terest attached to the subject^ and also, as the Author hopes 

 he may be allowed to infer, of the satisfactory manner in 

 which he has executed his task in the short treatise of which 

 he now offers a Third Edition. It has been his endeavour 

 to render the book worthy of the popularity it has acquired, 

 by adding in this Edition such improvements as the progress 

 of botanical science has rendered desirable to communicate 

 in a popular treatise.
