44 THE ORCHID REVIEW. (FEBRUARY, 1909. 
crocks and charcoal to kept it porous, will suit them. In potting, keep the 
young growths just below the rim of the pot, so that a plentiful supply of 
water can be given as soon as they become established. Care should be 
taken not to break the roots more than necessary. Work the compost 
carefully in between the roots, and top up with nice lumpy pieces, and add 
plenty of crocks and charcoal as the potting proceeds, so as to have an 
open compost, that water will pass through quickly when applied, as 
Phaiuses object very much to stagnant compost, or a close atmosphere. 
They like plenty of heat, but not a close atmosphere, and a little air should 
be given every day, using either the top or bottom ventilators, according 
to the outside conditions. Do not use both top and bottom ventilators at 
the same time or it will cause a nasty draught. The leaves must be 
sponged occasionally to keep them free from scale, but it must be carefully 
done, as they are very brittle, and easily crack and bruise. A nice warm 
corner at about 70°, where air can be given, will suit them well to start 
growing in, and after they get established the temperature can be lowered 
5°. During their growing season they will require an ample supply of 
water. If spot makes its appearance in the leaves, more air will soon check 
it. Plenty of air should be given during the summer months, so long as a 
draught is not caused, and the supply is put on gradually, so that they do 
not get chilled. 
PLEIONES that have finished flowering and are making new growths will 
want potting or top-dressing. They do better when potted annually, before 
they commence to make many roots, and a mixture similar to that advised 
for Phaius suits them. They are quite at home when suspended from the 
roof of the Cattleya house or warm end of the Intermediate house. They 
should be kept well syringed when they are growing, as they are rather 
subject to red spider. 
CATTLEYAS AND L2& IAs, during the winter months, when the house has 
to be kept a little dry, are liable to become infested with scale, and should 
be carefully gone over and sponged before the young growths begin to 
push up. A few will generally be found round the base of the growth, and 
no amount of spraying or fumigating will kill them, as they are under the 
skin, which should be carefully removed, and then with a brush remove the 
scale or it will get on the young growths as soon as they begin to push, 
and cripple them before the growth gets hard enough to withstand the 
attack. Ifthe young growths get yellow no amount of subsequent care will 
make the leaves and bulbs green again. When going through them for 
re-staging, any sickly plants should be placéd by themselves, or better still 
put into a stove temperature, where there is plenty of moisture in the 
atmosphere. If the compost has gone sour on top they should be top- 
dressed, care being taken not to break the roots, as every root is valuable
