 shall endeavor to review in the following section.

 country residences. It is to be presumed, that there 

 are few who are willing to contemplate a living col- 

 lection of trees and shrubs without experiencing the 

 pleasurable emotions which their elegance of form and 

 beauty of tint are fitted to inspire. In such as would 

 dispense with these enjoyments, the scientific instinct 

 must be very strong indeed. We trust that the vast 

 majority of our readers would rejoice to find a new 

 source of pleasure in an ornamental assemblage of

In the arrangement of the arboretum, there are cer- 

 tain orders and alliances which include the trees of 

 largest growth ; these claim special attention for the 

 selection of their position, as they not only require a
