GLOSSARY. 
perfluous water to pass away. The plant is potted into the 
mixture above mentioned, keeping the base of the stems a little 
elevated above the rim of the pot, and pressing the soil about the 
roots, which should be carefully spread out near the surface of 
the soil. For small plants it is advisable to use only moderately 
sized pots, though, once established, no plant appears to delight 
in abundant scope for its roots more than this, and if the proper 
precautionary measures are taken to secure a good drainage, a 
large shift may safely be given. Through the summer a cool 
shaded place, where the plant will receive plenty of air and be 
free from the drip of trees, should be selected for it, where it 
must be well watered and frequently stopped by pinching out the 
points of the shoots, to induce it to become dwarf and bushy, 
and thus consequently to increase the number of blossoms in the 
next season. In winter, the front shelf of a greenhouse, or floor 
of a low pit is most suitable. It is not tender, merely requiring 
to be protected from frost, but is very impatient of a confined 
damp atmosphere, or the absence of light.
