THE GREENHOUSE.

least neglect being frequently attended with irremediable effects. 
Watering should be done in the evening through the summer, 
and in the morning in winter. Plants which flower in the spring 
should be potted immediately afterwards ; those which bloom in 
summer should be done early in spring ; and the winter-flowering 
kinds require fresh earth in the summer months. Those which are 
naturally straggling in their growth should be frequently stopped, 
by pinching off the leading buds or points of the shoots, in toe 
early stages of their growth, discontinuing, however, after Mid¬ 
summer, or a quantity of unripe shoots will be an unceasing 
source of trouble through the winter. Climbing plants shou d 
be constantly secured in their proper places, or an unsightly mass 
of leaves alone will result. The requisite propagation should be 
done in summer, because the required increase is more easily 
obtained, and the object is attained with far less trouble ; and the 
appearance of disease or insects constantly watched for, and the 
proper remedies at once applied. Sulphur dusted over the af¬ 
fected parts is the best corrective for mildew, and other diseases 
arising from excessive moisture ; tobacco-smoke, or smelling salts, 
will eradicate green flies, and a high moist atmosphere is the only 
remedy of real worth against the ravages of the red spider; a sponge 
and clean water will remove scale and mealy bug; the frequent 
use of this and the syringe being perhaps the very best of all 
methods known for the extirpation of every kind of insect. 
We close this paper with a list of plants suitable for the green¬ 
house described, which are selected with a view to the production 
of flowers at all seasons, combined with as much variety as it is 
possible to have without other conveniences.
