 II. Ornamental Plants. 

 In addition to the ornamental trees and shrubs already dis- 

 cussed, there are numerous native herbaceous plants which are

 such as bogs and sand ridges, to replace weed- along garden 

 fences, and to be mingled in fern-beds, either on the north side 

 of the house, or in well-shaded rook-ferneries.
