TO HIS GRACE, 
HUGH, DUKE OF NORTHUMBERLAND, K.G. 
Soi Gee 
My Lorp 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, Miiler’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, 
Tue AUTHOR.
