Features of the Garden. 
THE method through which the Garden was built up by succes- 
sive additions resulted in an absence of combination between its 
several parts, in great measure a consequence of want of adequate 
funds to make the necessary alterations in the grounds. During 
the past thirty-two years, in which the Garden has been wholly 
under the administration of the Commissioners of H.M. Works, 
the bringing about of this combination has been in progress. 
The work is not yet completed, and the Plan of the Garden 
which is attached to this sketch shows the area of the Garden as 
it is laid out at this date—January 1921. Future editions will 
show further changes as the work of reconstruction proceeds. 
From its foundation the Botanic Garden has been devoted to 
the teaching of Botany, and its usefulness in this respect has 
determined the laying out of its area. 
Herbaceous Garden.—A considerable space is occupied by 
a collection of herbaceous plants arranged for study in natural 
orders. 
Rock Garden.—There is an extensive rockwork upon which 
alpine and rarer herbaceous plants are cultivated. 
Arboretum.—The whole of the western area of the Garden 
is in process of arrangement as an Arboretum of trees and shrubs, 
and the positions of some of the chief genera are indicated on 
the plan. The Coniferze are now placed in the ground adjacent 
to the Rock Garden. 
Herbaceous Border.—Along the North Boundary of the 
Arboretum a mixed Herbaceous Border has been planted. 
The Plant-Houses are still in process of reconstruction. 
So far as they have been rearranged at the present time they 
consist of a long range to the north of the herbaceous collection, 
composed of a Central Green-house (C), from the sides of which 
two Corridors run east and west. In the Entrance Porch (D) to 
the Central Green-house is a collection of Insectivorous Plants. 
From the Eastern Corridor two houses project to the south—one 
(A) occupied by plants of Dry Regions, the other (B) containing
