 In this part of the book is a complete list of hardy 

 Coniferae. A short popular description of each is 

 given, showing its habit, general form, and use as an 

 ornamental plant. The principal synonyms of each 

 are also given. 



Then there are treatises on the cultivation of 

 American plants, and on the newly -introduced Sikkim 

 Rhododendrons . The remainder consists of descrip- 

 tions of the principal hardy evergreen trees and 

 shrubs, with remarks on the situation best adapted 

 for each, and the soil and treatment it requires ; with 

 copious classified lists of the kinds best adapted for 

 particular soils and situations. We believe the latter 

 will form a useful guide to persons about to plant. 



It now only remains for us to offer our sincere 

 thanks to the numerous gentlemen who so kindly and 

 promptly assisted us by filling up our return papers. 

 We feel that particular reference to each will not be 

 thought necessary ; and we hope that our acknow- 

 ledgments thus collectively expressed will not be 

 considered as indicating in us a less appreciation of 

 their individual assistance.

 and Trees, we venture to solicit communications in
