CRATJEGUS. The thorns form one of the most beauti- 

 ful of the groups of small growing trees, and as they 

 are so neat in growth as to occupy comparatively little 

 space they should be largely planted in the garden and 

 in park and meadow land immediately outside its 

 boundaries. Atmospheric impurities have but little 

 effect upon them, and they are therefore well suited 

 for town and suburban gardens. The usual height of 

 thorns ranges from ten to fifteen feet, but specimens 

 twenty feet and more high are not uncommon. The 

 varieties of the hawthorn (C. oxycantha) are the most 

 useful for general planting, and the best of these are 

 Double Pink (C. oxycantha rosea), the flowers bright pink 

 and quite double ; Double Scarlet (C. oxycantha coccinea 

 plena), brilliant red, one of the finest of all the flowering 

 trees with red blossoms, and should have a place in 

 every garden ; Double White (C. oxycantha multiplex), 

 pure white, the flowers perfectly double and produced 

 in dense masses ; Single Scarlet (C. oxycantha punicea), 

 bright scarlet, very beautiful ; Weeping Thorn (C. 

 oxycantha pendula), a charming variety, the growth 

 graceful and the flowers single and pure white. The 

 varieties of the Cockspur Thorn (C. crus-galli) rank 

 next in importance, and should be freely utilised in the 

 creation of garden scenery where the area will admit of 

 a somewhat full representation of flowering trees. The 

 most desirable of these are Carrier's variety (C. crus- 

 galli Carrieri), which has large single flowers, white on 

 opening, changing to flesh colour ; Lay's variety (C. 

 crus-galli Layi), bright pink, and C. crus-galli splen- 

 dent, bright pink. The flowers of the typical form 

 are white, and these are followed by large clusters 

 of crimson berries which are very attractive during 

 the autumn. The tansy-leaved thorn (C. tanacetifolia),
