TO HIS GRACE, 

 HUGH, DUKE OF NORTHUMBERLAND, K.G. 



Sfc. S$c. 



MY LORD DUKE, 



IN dedicating to Your Grace the accompanying 

 Volumes, I am anxious to show how fully I appreciate the 

 encouragement which your ancestors and yourself have always 

 given to gardening pursuits, and more especially to the intro- 

 duction and cultivation of foreign trees and shrubs. How 

 much the British Arboretum is indebted to the noble family of 

 Northumberland, for the introduction of trees and shrubs from 

 America during the last century, is evinced by the Hortus 

 Kewensis, Miller's Dictionary, and other works which record 

 the names of the first introducers of foreign plants ; and how 

 various and magnificent are the specimens of foreign trees which 

 exist in the grounds at Syon, the numerous portraits of them 

 which are given in the Volumes now submitted to the public 

 bear ample testimony. 



For the kindness which Your Grace has evinced, in having had 

 these portraits made expressly for my work, I am desirous that 

 this dedication should be considered as a public memorial of my 

 lasting gratitude. 



I have the honour to subscribe myself 

 Your Grace's 



Very obedient humble Servant, 



THE AUTHOR. 



Bayswater, May 20. 1838.
