species, with compound leaves (eight to ten leaflets) and pea-shaped 

 pale yellow flowers, is hardy everj-where, easily grown and adaptive, 

 and makes one of the best sturdy hedges. 



C. spinosa D C. (103), also from Siberia, similar in leaf and flower, 

 is a low shrub (four to six feet) with long, thorny branches, but does 

 not appear to make good hedges. It is specially adapted for sandy soils. 



An entirely different type as regards foliage, having only two to 

 four leaflets, is represented by — 



C. friitescens D C. (103 bis), from Southern Russia and China, hardy 

 to Ottawa. This is a small tree, half the size of arborescens, and more 

 graceful and attractive, with its golden-yellow inch-long flowers. 



Several other Asiatic dwarfs of this genus are found equally hardy 

 but without points of superiority, except perhaps C. pygmcea D C, a 

 small shrub with fine foliage and handsome golden-yellow flowers. 



Cladrastis. C. tindoria Raf. (104) {Virgilea liitea), Yellow-Wood. 

 This small to medium-sized tree, often even shrub-like in habit, of 

 limited range in Kentucky and Tennessee, but hardy to semi-hardy into 

 Canada, i-s a first-class ornament for small places, with short trunk and 

 spreading branch habit in refined curv'es. The foliage is made up of 

 rather large compound leaves, formed of small, short, pale green leaflets 

 drooping gracefully and turning bright yellow; ■ it has equally graceful 

 loose clusters of fragrant white, pea-shaped, wistaria-like flowers (June), 

 hanging from the ends of the little branchlets. The long leaf-stalks, re- 

 maining into winter and enclosing the buds, are interesting, but some- 

 what detractive from its winter aspect, which otherwise its smooth, gray, 

 beech-like bark renders attractive. It is a moderately rapid grower, 

 and adaptive to various soils.

Fraxinus. A genus economically very valuable, with thirty to forty 

 species of large to small trees, in all parts of the temperate zone; is orna- 

 mentally of less value than many others, because of the stiff, open, bare, 

 and spreading branch habit. Yet they are interesting in their finely- 

 ridged, whitish-gray to dark bark, and their elegant foliage of light hue, 

 which, however, is late in making its appearance, and early in falling. 

 All are light-needing and of medium rate of growth. Their tracing 

 root system permits easy transplanting. They are adaptive to wet
