imposing any check. At the turn of the year these should 
be shaken out and re-potted in fresh soil in smallish pots, 
and put into a temperature of 50° to encourage growth. 
When inclined to move, the heat should be increased to 
6U°, and after a time to 70°, but beyond that it will not 
be safe to increase the temperature. When the plants so 
treated have filled their pots with roots they should be 
shifted to the next size, and be again and again shifted as 
needful, but never until the pots are filled with roots, and 
never beyond a reasonable size of pot. If the shifting 
into larger and larger pots is carried too far, there will be 
immense growth but no flowers, therefore you may reason- 
ably stop when the plants are in 8-inch or 10-inch pots. 
Then let them flower, and you will be well rewarded. As 
a matter of course they must be kept neatly staked, and 
flowers that appear before the plants have attained to a 
suitable size must be pinched out. A compost consisting 
of loam, leaf-mould, and very old manure from a hotbed 
is the best for them; rank or fresh manure is objection- 
able, and liquid manure should be given occasionally.
