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 (Alnus glutinosus foliis aureis) 

 useful for planting on the margin of ponds and lakes. 

 Golden-leaved Laburnum (L. vulgar e 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 (Ulmus 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
