specimens will suffice. The weeping trees appear to 
the best advantage when arranged as single specimens 
on the lawn. 
GoLDEN-LEAVED.—The finest trees with golden leaf- 
age are: The Golden Alder (A/nus glutinosus foliis aureis) 
useful for planting on the margin of ponds and lakes. 
Golden-leaved Laburnum (L. vulgare aureum), bright 
in colour and useful in small gardens. Negundo (Acer) 
fraxinifolium aureo variegatum, a free growing tree of 
small growth, the leaves edged with bright gold. 
Golden Poplar (Populus monilifera canadensis aurea), a 
richly coloured tree of free growth which by annual 
prunings can be readily kept to any desired size. 
Golden Oak (Quercus pedunculata concordia), the finest of 
all the golden trees for choice positions. The tree is of 
comparatively slow growth and the leaves are of the 
richest golden hue. Golden Elm (Usmus campestris 
aurea) is a capital companion to the Golden Oak being 
of moderate growth and very rich in colour. 
BRONZE AND PuRPLE-LEAVED.—The most effective 
trees with bronze and purple leaves are—Purple Birch 
(Betula alba purpurea) an elegant tree with purple leaves. 
Purple Beech (Fagus sylvatica purpurea) the finest of all 
the purple-leaved trees and too well known to need 
comment. There is also a form of the Purple Beech of 
pendent habit which also can be highly recommended. 
Purple Plum (Prunus Pissardi) is a much smaller growing 
tree than either of the foregoing and most desirable for 
small gardens, the leaves are of a rich purple hue. 
SILVERY-LEAVED.—The silvery-leaved trees are few 
in number and three only will be mentioned. These 
are Dimorphanthus mandschurica variegata, a very hand- 
some small growing tree with bi-pinnate leaves measur- 
ing two or more feet across the base, the leaflets 
broadly margined with white. Negundo (Acer) fraxini- 
folium albo variegatum, a well-known, small growing tree
