rich soil—ground that was manured for a previous crop, 
but which has had no fresh manure since. About the 
middle of April is a good time. If sown too early the 
plants are apt to run to seed. Let the drills be 1 foot 
apart, and thin the seedlings out to a distance of 9 inches 
apart in the rows. 
SaLvia.—Most of the species and varieties of this vast 
genus can be readily propagated by cuttings of young 
shoots inserted in spring in sandy soil, kept close and 
shaded until rooted; the annual sorts by seed sown in 
March, either indoors or outside, according to their 
nature. 
SAMBUCUS (ELDER).—The hardy herbaceous kinds are 
increased by division in autumn or spring; the shrubby 
species and varieties by cuttings of ripe shoots outdoors 
in October or March. 
SANCHEZ1IA.—These ornamental-foliaged stove plants 
are readily propagated by cuttings of tops or side-shoots 
in spring or summer. 
SAPONARIA.—S. calabrica and its varieties are sown in 
April for summer flowering, and in September for spring 
bedding. . 
SARRACENIA.—These interesting North American 
Pitcher Plants are propagated by division of the crowns 
just as growth is commencing, potting them in fibrous 
peat, with most of the dust and earthy matter removed, 
mixed with sphagnum moss and a few lumps of char- 
coal. They are then placed in a cool, moist, shady 
position in the greenhouse and are frequently syringed 
overhead. 
Savory.—Summer Savory (Satureia hortensis) is an 
annual. Seed for an early supply is sown in gentle heat 
in March, and the seedlings are planted out on a warm,
