the ravages of slugs, and when grown to a large size, they are often 
infested by caterpillars, particularly those of the green-veined White 
Butterfly (Pontia Napi) which secrets itself in the head, and is hard 
to be discovered, the Turnip Butterfly (Pontia Rapae.) The Cab¬ 
bages Brightline Moth, (Mamestre oleracea) and the common Cab¬ 
bage Moth (Mamestre Brassicae.) The only way of keeping clear 
of these is to hand-pick them. 
They are also infested with the larvae of a fly, which causes the 
clubbing at the roots; many means have been adopted to prevent 
this, none of which, to the best of our knowledge, are efficient reme¬ 
dies. Charcoal dust has been found to have a good effect as a pre¬ 
ventative, when spread over, and dug into the bed, and soot has been 
found to have a similar effect, but neither can be depended upon, at 
all times.

Article III.—CULTURE OF THE BOUVARDIA TRIPHILLA. 
About the middle of April, collect all the Bouvardias together, from 
the places where they have been kept through the dormant season : 
some amongst the orange tubs, others in cold frames, and others un¬ 
der the stage of the greenhouse. 
Turn them all out of their pots, and shake the soil completely 
from the roots : thin off most of the large roots, yet retain as many 
of the fine fibrous ones as possible. At the same time, cut down all 
the former years’ shoots, retaining only two, three, or four eyes on 
each, according to the age or strength of the plant. * 
Plant them in pots suitable to the size of the plants, taking care 
never to overpot them, nor to cramp the roots by confinement. 
When potted, water them to settle the earth about their roots, and 
place them in a cold frame, covered with hay and mats at night: 
keep the lights close during the night, and even in the day, (unless 
the sun be very strong upon them,) till they begin to grow; then 
give them portions of air, according to the day, and their advance in 
growth. Subsequently, leave the lights off through the day, and 
lastly, do not put them on at night. 
In about a week after they have been thus exposed, plant them 
finally out for the season, either in clumps by themselves, or distri¬ 
buted among other plants, after which they are soon in fine bloom, 
and continue to flower till Christmas. By the autumn, some of the
