sheep, pig, and cow manure, and in an artificial form it is 
obtainable in nitrate of soda, sulphate of ammonia, guano, 
etc. Phosphoric acid is contained in bones, superphosphate, 
etc., and potash in the form of sulphate of potash, kainit, 
and wood-ashes, These elements are contained in suit- 
able proportions in all good Carnation manures sold by the 
nurserymen. Soot is also an excellent fertiliser, and should 
be applied in the form of soot-water, obtained by placing 
half a bushel of soot in a sack in a tub of water, and allow- 
ing it to soak, using the water in a clear state, and greatly 
diluted. In the same way the natural manures may be pre- 
pared and used in a diluted liquid form. To induce or 
hasten flowering, superphosphate sprinkled at the rate of a 
quarter of an ounce to each plant on benches, or dissolved 
in water for pot-plants, will have a good effect.
