which may infest them whilst in their resting quarters. It is unnecessary 
to state that this should be exterminated. 
ODONTOGLOSSUM CITROSMUM generally thrives when grown suspended 
in the Mexican house, but now that the plants are about completing their 
growths, they will benefit from a slightly warmer and more genial 
‘atmosphere until their growths are fully completed. The plants should 
still be afforded plenty of water at the roots until the growth is finished. 
Plants of O. grande, O. Schlieperianum, and allied species, as they pass 
-out of bloom, should be induced to rest by being placed in a dry position in 
a cool Intermediate house. . Insleayi and its varieties splendens and leo- 
pardinum are producing flower spikes, and must have liberal treatment, 
receiving water whenever they require it. After the flowers fade the plants 
should be rested and treated in the same way as O. grande. Plants of O. 
‘crispum and hybrids may in the early part of the month be repotted, should 
they be in the desired condition, that is if the temperature can be 
maintained at its proper figures. Where the temperatures run down 
considerably during a spell of cold weather it had better be deferred until 
the early spring months. 
CG@LOGYNE CRISTATA and its varieties are nearing the completion of their 
eason’s growth, and will soon be pushing flower spikes from the new 
pseudobulbs, at which stage the supply of water at the roots should be 
slightly reduced, but not to such an extent as to cause the plants to suffer. 
Well-rooted, pot-bound specimens may receive at intervals, until the 
flowering stage, weak manure water, preferably prepared from cow dung. 
Those Ccelogynes, such as C. barbata, ocellata, and others, that are 
‘developing flower spikes, should have water whenever they become dry. 
CyMBIDIUMS.— Plants of C. Lowianum, C. Tracyanum, and the many 
hybrids that are now showing their flower spikes, should have water 
whenever the compost becomes dry, whilst others that are backward in 
this respect should be kept on the dry side until their spikes are observed 
to be pushing. Plants of C. grandiflorum that have finished their growth 
and are pushing flower spikes should be placed in a cool, light position, and 
the roots kept on the dry side during the winter. If kept at all moist 
‘during the winter months the flower buds invariably turn black and fall off. 
GENERAL REMARKS.—The season has now arrived when the cleansing of 
the houses and their inmates must have attention. The glass must be made 
thoroughly clean, to admit every atom of light possible, and the woodwork, 
walls, and stages to destroy any pest which infect such places. The 
eradication of all insect pests is more easily accomplished during the 
winter months than in the busy growing season, therefore this work should 
be pushed on rapidly. It is needless to state that if such work is to be 
effectual it must be done thoroughly.
