times until the fly is dead. In sections where tobacco is 
plenty, a sprinkling of the stems or refuse from tobacco 
stemmeries among the plants will keepthem away. We 
always keep plenty of tobacco stems in all our Rose 
houses, either scattered among the plants or on the floor 
or under the benches, and in consequence never have 
any trouble from Green Fly. If the plants are grown out 
of doors, and infested with fly, a liquid solution made 
from tobacco stems will be found an efficient method of 
working their destruction. Take some tobacco stems and 
place in a tub or vessel of some kind, and pour boiling 
water upon them until the liquid has the color of strong 
tea; after it cools of sufficiently to handle it, apply it to 
the Rose with a syringe or wisk broom; a little soft soap 
or whale oil soap added to the solution will greatly aid 
it in its efficacy. 
MILDEW. 
This is a fungous disease often caused by great and sud- 
den atmospheric changes, and a long contihuance of 
damp cloudy weather. The best remedy is sulphur, and 
should be applied the moment the disease makes its 
appearance, which is in the form of a white or grayish 
substance covering the leaves and causing them to ecrim- 
ple and become deformed. The plants should be sprin- 
kled first with water so that the sulphur will stick; the 
best plan is to apply it in the morning while the dew is 
upon the plants. After a few days the sulphur will all 
fall off and the mildew disappeai. This treatment ap- 
plies to Roses grown both in-doors and out, but if grown 
in a pit or greenhouse the best way is to mix the sulphur 
with water to the consistency of a good stiff paint, and 
apply it to the pipes or heating apparatus in the house 
with a brush. The fumes given off from this will at once 
cheek the ravages of the mildew.
