 SAND. The u.se and value of Sand for plant-pro- 

 pag^ation, and for intermixing with composts, t&c, 

 g-eiierally, 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 

 cutting's, 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 l>e potted in soil, according as each may 

 reiiuire, 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. 

 K-oad 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 



Sand — continued. 

 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 esoape for any undue accumulation of water.

 sistent, nrceolate-globo.se, slightly inflated, with a short, six-cleft

 cavities at the base ; stamens six, hypogynous, much shorter than
