These figures should be maintained as nearly as possible, but due regard 
should be taken of the fluctuations of the temperature outside. If the 
weather be cold do not attempt to reach the higher temperatures by 
excessive firing, which would do more harm than allowing them to recede 
a degree or two, and during a spell of severe weather the fire-heat may be 
economised by letting the blinds down at night, or laying mats or other 
coverings on the glass. These, however, should be removed in the day 
time, as it is important that the plants should receive all the light possible 
at this dull season. 
Ventilate as freely as possible during mild weather, but chiefly by means 
of the bottom ventilators, for a stagnant atmosphere is detrimental to the 
health of the plants. Do not let the atmosphere become dry, but damp the 
paths and walls once or twice a day, according to the amount of fire-heat 
used. Watering operations must still be carried on with caution, and much 
the same as last month. Keep a sharp look-out for insects, for cleanliness 
is of the highest importance, and a little extra attention in this direction 
will save much labour hereafter when time is more valuable. A sharp watch 
should be kept for slugs, and if signs of them are apparent some lettuce 
or cabbage leaves should be laid down and examined carefully every 
morning. A little cotton-wool placed round the base of a flower spike will 
often preserve it from these marauders. Cockroaches, too, should be kept 
down at all costs, for it is useless to attempt to grow Orchids in a house 
infested with these pests, which devour young roots, flower spikes, and 
almost anything else without mercy. 
In the Cool house many things are at rest; the principal work will be to 
give due attention to watering and keeping the atmosphere in a healthy 
condition. Those plants which are commencing to grow should be kept 
rather moister than before, and any that are making active growth, such as 
Ada aurantica, will benefit by rather more liberal treatment. <A_ few 
Odontoglossums are now in bloom, and may be kept slightly drier than 
those beginning to grow. Masdevallias must be very carefully watered. A 
few kinds are in bloom, of which the beautiful M. tovarensis is the best, and 
its pure white flowers are invaluable at this season. ie
