rich or retentive of moisture, the plants are very subject to 
die suddenly, when in full vigour. 
In summer it should be placed in a cold frame or pits 
where the lights can be removed entirely in dull weather and 
at nights during summer, but kept on during boisterous and wet 
weather. It is a mistake to suppose that. greenhouse plants 
should be placed out.of doors and subjected to all the vicissi- 
tudes of the weather during summer. As regards delicate sorts 
like the present, the sudden changes which they are subjected 
to when placed out of doors are very destructive to them; they 
should be kept in as small pots as possible, and placed in an 
airy cool part of the green-house where there is plenty of light 
during winter, but where there is no danger of sudden 
changes in the temperature, by fire-heat or neglect of water- 
ing. More injury is done by too much fire heat and too little 
water to such plants during winter, than by all other causes 
together, frost alone excepted,
