vented from blooming in spring or early summer by plucking 

 the incipient buds, or by deferring their winter pruning until 

 the leaf is putting forth, and then cutting them closely back, 

 they will- probably furnish abundance of blossoms late in sum- 

 mer or in the fall. Transplanting or root pruning, with cut- 

 ting back in the fall or very early spring, will be found con- 

 ducive to the same result ; but any or all of these means should 

 be accompanied by high compost or liquid manuring and clean 

 and careful culture. For Running Roses, see page 484. 



Rose-bushes are infested with various insects, particularly 

 the Aphis and Scale insect, for which the remedies directed 

 pages 264 and 265 may be used. The Rose w r orm or slug, larva 

 of Selandria (Blennocampa) Rosae, is still more injurious. It is 

 a small, greenish, smooth, semitransparent worm, resembling 

 the Cherry slug, page 275, about half an inch long, found often 

 in June on the under side of the leaves of rose-bushes, which 

 it eats until only the veins and the thin skin of the upper side 

 of the leaf are left. They do not generally eat over the whole 

 leaf, but spot it ; but in moist seasons they abound, and will 

 then sweep the rose foliage as if fire had scorched it. 



Sowing slaked lime, or dry ashes, or sulphur upon the 

 bushes, or syringing them with weak ley or whale-oil soap may 

 destroy the worm, but vigorous health in the plants generally 

 prevents it. 



19. ROSE OF SHARON, Hibiscus Syriacus, known also as 

 Althea, or August Flower. Increased from layers, cuttings, or 

 seeds. 



20. SCARLET QUINCE, Cydonia japonica (formerly Pyrus 

 japonica). Increased by cuttings of the root or by layers, 

 and sparingly by offshoots. Extremely showy and of pretty 

 foliage. 



21. SPIRE A, Reeves's, Double-blossomed, &c., Spirea Eeve- 

 sii, prunifolia flore pleno, &c. A class of pretty white- 

 flowering shrubs, spreading freely by offshoots, or increased by 

 layers. 



22. SNOWBALL, Guelder Rose, Viburnam opulus. An old 

 and well-known shrub ; increased from offshoots, and still more 

 readily by layers.
