liable. Fumigation is the best remedy, and it should be
undertaken in the evening; a still atmosphere renders the operation more
certain. Water carefully on the following morning, and shade from the
sun.

By September the plants should be in large 60-pots, and it is then quite
time to begin the preparation for wintering. Some growers put them in
heat, and are successful, but the heat must be very moderate, and even
then we regard the practice as dangerous. Place the plants near the
glass, and at one end of the house where they will obtain plenty of side
light, as well as light from above. During severe frosts it may be well
to draw them back or remove them to a shelf lower down and towards the
centre of the house, but they must be restored as soon as possible to
the fullest light obtainable, as they have to do all their growth under
glass. The more air that can safely be given, the better, and dispense
with fire-heat if a temperature of 45 deg. to 55 deg. can be maintained without
it.

When growth commences in spring, which will generally be early in March,
give each plant its final shift into eight-or ten-inch pots. This must
be done before the buds push up, or there will be more foliage than
flowers.

The following is the compost we advise: one bushel good yellow loam,
half-bushel leaf-soil, one gallon silver sand, a pound of Sutton's A 1
Garden Manure, and a pint of soot, well mixed at least ten days before
use. Any sourness in the soil will be fatal to flowering. The compost
must be carefully 'firmed' into the pots, but no severe pressure should
be employed, or the roots will not run freely.

Neglect as to temperature or humidity will have to be paid for in long
joints, green fly, red spider, or in some other way. But there are no
plants of high quality that grow more thriftily if protected from cold
winds and kept perfectly clean. A light airy greenhouse is their proper
place, and they must have ample headroom.

After the pots are filled with roots, not before, manure water may be
administered until the flower-heads begin to show colour, when pure soft
water only should be used. About a fortnight in advance of the full
display the branches must be tied to supports. If skilfully managed the
supports will not be visible.

It may be that a few large specimens are required. If so, shift the most
promising plants into 6-size pots. These large Calceolarias will need
regular supplies of liquid manure until the blo
