Azaleas Infested with Thrips. — Young Gardener. — The plants are badly 
infested with thrips, which has been brought about, we apprehend, by keeping the 
atmosphere of the house too dry and hot. Remove them from the conservatory, 
and give the plants a thorough good washing with the syringe or garden-engine, 
and take them to the greenhouse, previously removing all the plants in flower, and 
give them a good dose of tobacco-smoke. There are several ways of managing this, 
but we have never found anything better than the following method : — Take some 
good tobacco-paper, strip it into small pieces, and, if it is not sufficiently moist 
from the tobacco-juice, damp it with clean water — the object of damping it being to 
prevent the fumes rising dry and hot, and at the same time to keep the paper from 
flaring ; for if either mishap take place, the leaves of the plants will be scorched, 
and they will suffer a large amount of injury. On the other hand, the paper must 
not be made too moist, or it will generate steam and do no good. The plants should 
be thoroughly dry, and the house shut up close, to prevent the escape of the smoke, 
and if there are any blinds to the house they should be tolled down ; failing that, 
it will be advisable to throw a few mats over the roof in the case of small houses. 
Fill the house full enough of smoke to prevent your seeing farther than a foot from 
the glass. Use a twenty-four size pot, with a hole knocked in the side, and a 
common pair of bellows, with a few red-hot cinders, upon which to place a few 
pieces of dry brown paper, then a little tobacco-paper rather dry, and finally fiU in 
with the moist paper ; by this means there will be no difficulty in igniting it. To 
render it unnecessary to go inside, have a hole bored through the woodwork of one 
or two of the front lights to insei't the nozzle of the bellows, and stand the pot upon 
a slate on the stage. It will be necessary to go inside to add fresh paper and stir 
it up, to keep it from burning toojmuch in one place.
