’ SAND. The use and value of Sand for plant-pro- 
pagation, and for intermixing with composts, &c.,. 
. generally, are known to nearly every gardener. Sand 
tends to insure porosity, by keeping composts open, and, 
when laid over the surface of pans or pots prepared for 
cuttings, settles more closely, on being watered, than 
does soil, and so holds the cuttings firm, and excludes 
air. Numerous sorts of cuttings are rooted best in Sand 
alone, as this substance contains nothing which can de- 
compose, and prevent the formation of roots. While there 
is an advantage in this, Sand, on the other hand, contains 
in itself nothing nutritive for supporting plants; they 
must therefore be potted in soil, according as each may 
require, soon after roots are formed. Water is sufficient 
for supplying all that tender little rootlets need for a 
time, until the plants are sufficiently strong to be potted. 
Silver Sand is best, and is that most extensively used: 
the coarser it is, the better. Sand from the sea-coast 
is by some gardeners largely employed for propagating. 
Road Sand is invaluable for mixing in composts, especially 
those for growing such plants as Carnations; it is usually 
coarse and sharp, from being washed by heavy rains. 
Although Sand is so generally used in composts, yet 
its place may be taken with advantage by charcoal or 
charred soil, when either is procurable. Charcoal is of 
an enduring nature, and possesses the property of 
absorbing gases, which Sand does not; it also acts most 
effectually in keeping a compost open. Sand is valuable

for placing around tender bulbs when planting, to pre- 
serve them from injury by being in contact with decom- 
posing substances in the soil, and to provide a ready 
means of escape for any undue accumulation of water,

Natal). ORD. Liliaceew. A monotypic genus. The species 
is a pretty, tuberous-rooted, erect-growing herb, with 
simple, leafy stems. For culture, see Gloriosa. 
S. aurantiaca (orange-coloured).* fl. orange-coloured, showy, 
nodding, on axillary, solitary, ebracteate pedicels ; perianth per- 
sistent, urceolate-globose, slightly inflated, with a short, six-cleft 
mouth, and haying six short horns or spurs forming nectariferous 
cavities at the base ; stamens six, hypogynous, much shorter than 
the perianth. Z. lanceolate, with a sometimes cirrhose acumen ; 
upper cauline and floral ones similar, or the uppermost ones 
smaller. A. 1ift. Natal, 1852. (B. M. 4716.)
