SEPTEMBER, 1908.] THE ORCHID REVIEW. 271 
water cannot penetrate. Place them in a light position, and keep them 
warm and moist, then no difficulty will be experienced in establishing them. 
Do not rest seedlings of any sort, but grow them on until they become strong 
enough to flower. 
CATTLEYAS that have made up their growth should be sorted out from 
those that are still growing, and staged by themselves at one end of the 
house, where they can be given extra ventilation, and a little less moisture. 
If the grower is lucky enough to possess two houses, they can be still better 
handled. The autumn-flowering section will be pushing up their flower 
spikes, and should be given every encouragement to produce fine flowers. 
As soon as the spikes are above the sheath they should be staked up, to 
prevent them from getting broken. Slugs and cockroaches should be 
trapped, or they will soon play havoc among Cattleya buds. A little arsenic 
and treacle placed on small pieces of glass will be found a good thing to. 
clear out cockroaches, but care must, of course, be taken in using this 
mixture. A few lettuce leaves will make a good trap for slugs, especially 
if looked over with a lantern after dark. 
CyPRIPEDIUMS will be pushing up their spikes very rapidly now, and 
should be staked neatly to give the flowers every chance to expand. 
Cypripediums do not, as arule, get bothered with slugs or cockroaches; 
thrip seems to be their greatest enemy. They should not be allowed to 
become dry at any time, or small flowers will be the result. When in flower, 
if a little care istaken not to let moisture condense on the flowers, they will 
last in perfection for two to three months, and make:a fine show when taste- 
fully staged with maidenhair fern. 
ONCIDIUM varicosum, crispum, Forbesii, &c., will also be pushing up 
their flower spikes. Slugs are particularly fond of these spikes, so they must 
be carefully watched, for a piece of cotton wool wound round the spikes at 
the base will help to keep them off. This is a beautiful class of Orchid, 
and worth a little extra trouble, as they make a very fine show in the 
dullest months of the year, and every spike is of value for grouping. 
OpontocLossums that have been newly potted should be sprayed 
overhead, and syringed between the pots, to keep the bulbs plump, and get 
the plants re-established. It will also keep the potting compost in a good 
condition for rooting into without constantly watering the plants, which is 
often a cause of the young roots dying off, and instead of the plants 
improving with repotting they go back, and the potting mixture gets the 
blame instead of the watering pot, or the grower. 
TEMPERATURES will have to be closely watched, as we may expect frosts 
at any time from now, and carelessness in firing will often spoil a summer’s 
work. Where blinds can be used they should he run out as an extra 
precaution. It only takes a few minutes to run out a lot of blinds, and will
