this, protection must be given by covering the out- 
side of the house with mats or canvas during frosty 
weather. When the plants commence growing, 
examine them frequently for the grub, and upon 
the first appearance of green-fly, fumigate with 
tobacco ; and this will possibly require to be 
repeated every nine days or fortnight. Water the 
paths occasionally to keep up a moist atmosphere, 
and in the morning during fine weather let the 
plants be syringed over, and air admitted on all 
favourable occasions. If the least signs of mildew 
is observed, let sulphur be applied immediately, for 
should this disease once get thoroughly established, 
there will be some difficulty in eradicating it. The 
syringing must be discontinued when the plants are 
about to bloom. 
If it is desired to remove any plants to flower in 
the greenhouse or conservatory, let this be done a 
week or nine days before the blooms are likely to 
expand, when they will have somewhat recovered 
the change of temperature by the time they come 
into bloom, and will last much longer in flower in 
consequence. If allowed to bloom in the forcing 
house, shading must be provided and applied when 
necessary ; air must also be admitted more abun- 
dantly, and less fire heat used. Plants which were 
brought into the forcing house in December will 
bloom about the middle of March. To keep up a 
succession, introduce another supply in January and 
again in February, they may then be had in bloom 
from March till June. 
After the plants are gone out of bloom, harden
