SOAP-BOILERS' ASHES. 



Although these are sometimes recommended as 

 manure the}' really have very little manurial value. 

 When raw "they are positively injurious. In this 

 state they are composed of carbonate, sulphuret, 

 and sulphite of lime. If exposed to the atmosphere 

 for a few days the sulphuret and sulphite absorb 

 more oxygen and become sulphate of lime, or 

 gypsum. They may be applied to land that is 

 deficient in lime, but for heavy land the " hotter " 

 forms of lime are to be preferred. 



SOBOLEWSKYA. 



Hardy annual herbs (ord. Cruciferae) of erect, 

 branching habit. Propagation, by seeds sown out- 

 doors. Ordinary garden soil.

Hand-List). 



SOBRALIA. 



Description. Tall-growing Orchids (ord. Orchid- 

 acese), with leafy, Reed-like stems which do not 

 become pseudo-bulbous, and very thick, fleshy 

 roots. The large, showy flowers are produced from 

 the tips of the stems, and though fleeting there 

 is a succession of them. All are exceedingly 

 easy to grow. They like the heat of the warmest 

 houses, but will do in an intermediate temperature. 



Propagation and Soil. By division and im- 

 ported pieces. The plants are wholly terrestrial, 

 and thus the compost must be substantial. Fibrous 

 peat and loam in equal proportions, with sand and 

 a few pieces of charcoal, will suit. Free drainage. 



Other Cultural Points. The plants must never 

 be dried off, although in winter the supply of 

 moisture may be reduced. Liquid cow manure 

 just before flowering is useful. They may be 

 grown with a mixed collection of stove plants.

 SOLANDRA. 



A small genus of beautiful climbing stove shrubs 

 (ord. Solanaceas), of attractive appearance when in 

 bloom. Propagation, by cuttings, in heat, in light 

 soil. Cuttings of the flowering shoots will give 

 small, blooming plants. Soil, good loam. The 

 plants should have liberal treatment in their early 

 stages, afterwards withholding water until the 

 leaves begin to drop. This drastic treatment 

 generally induces the Solandras to flower profusely.
