twice gently than to give one strong dose. Slugs and cockroaches must be 
kept down or they will soon destroy a lot of flowers and spikes. They can 
be trapped with lettuce leaves or in fact any green stuff, and poison for 
cockroaches and woodlice will generally clear both out in a short time. 
TEMPERATURES.—Fires must be carefully lcoked after now, as a sudden 
check will doa lot of harm. Night frosts may be expected at any time, 
and the fires should be kept clean and ready to use at any time that they 
may be wanted, without having to get the pipes red hot to get up tem- 
peratures quickly, which is a sure method of breeding thrip and red spider, ° 
as well as causing injury to the plants. 
DENDROBIUM FORMOSUM AND D. PHAL#&NOpPsIS will be in full flower, 
and should be kept on the dry side as soon as the flowers are fully expanded, 
when they will last a long time in perfection, especially if staged in a dry 
house and kept warm. They should not be given a lower temperature than 
60° at any time. The Cattleya house isa good place to rest them in; and 
they should be suspended from the roof at the warm end. They will need 
very little water until they commence to grow again. 
La@Lias, CATTLEYAS AND THEIR HYBRIDS.—All the autumn flowering 
varieties should be carefully watched for water until the flowers are 
expanded, and with the species and numerous hybrids a fine show can be 
maintained throughout the winter season. Those which are pushing up 
their spikes can be staged together at the cooler end of the Cattleya house, 
and those that are growing can be staged at the warm end of the house. 
In the case of the hybrids it is almost impossible to rest the whole house, 
as can be done with species only, for the former are still growing during the 
winter months. I don’t think keeping the house a little warmer and 
moister to suit the hybrids makes any difference to the species, for they 
seem to flower just as well as they did when they used to get baked, and 
certainly there are not as many deaths now as by the old treatment. Where 
the plants have not been densely shaded during the summer months, they 
will throw up fine spikes, without shrivelling the bulbs. 
In washing down and re-staging this house the plants should be looked 
over for scale, as it will often be found on the new growths, and if not 
removed will make the leaves look very unsightly. A light spraying with 
insecticide after the growths are made up will keep them clean, but if 
insecticide is used while the growths are young it must be carefully applied, 
and rather under strength, for if it lodges in the growths they are liable to 
rot away before the damage can be seen. All young growths should be 
neatly staked and tied up, for if allowed to bend over in moving about they 
generally rot off, and not only bulb but flower spike is lost. 
Lelia anceps will also be pushing up its spikes, and these should be 
staked and kept well tied up, as they easily get broken when moving about.
