28 THE ORCHID REVIEW. [JANuaRY, 1908. 
The temperatures of the different departments during the present month 
should be kept about as follows :— 
Odontoglossum house.—Day, 50° to 55°, with sun, 58°; Night, 50°; 
Morning, 45°. 
Cattleya or Intermediate house.—Day, 60°, with sun, 65°: Night, 55°; 
Morning, 50°. 
East Indian house.—Day, 65°, with sun, 70°; Night, 60°; Morning, 55°. 
These figures are intended as a guide, but regard must be paid to the 
outside conditions. If the weather is mild and genial a slight increase may 
be allowed, but during a cold spell a slight fall is preferable to forcing the 
fires too hard. 
CooL OR ODONTOGLOSSUM HOUSE.—A good many flower spikes will 
be pushing in this house, and plants in this condition should receive slightly 
more water, as well as those in flower. Should any spikes appear on 
weakly plants it is better to pinch them out as soon as possible, for the 
strain of flowering only makes matters worse, and weak, puny spikes are of 
little decorative value. Sophronitis grandiflora will now be producing a 
wealth of its brilliant flowers. . 
CATTLEYA OR INTERMEDIATE HOUSE.—Lelia anceps and some other 
Mexican species will now be making a fine show. Cattleya Trianz and C. 
Percivaliana will be rapidily developing their buds, and should be placed at 
the warm end of the Cattleya house. Fluctuation of temperature should 
be avoided, or some of the buds may turn yellow, and fail to open. Very 
little will require attention here beyond the ordinary routine work. 
WakM OR DENDROBIUM HOUSE.—Many of the Dendrobiums are now 
developing their buds, and should be allowed to come away. steadily, as too 
much heat or too much water at the root tends to produce blooms of poor 
quality, and some may turn yellow and fall off. Strong plants will produce 
a profusion of flowers during the next few months, foremost among them 
being D. nobile, Wardianum, crassinode and aureum, with their numerous 
hybrids. Here also little will require attention beyond routine work, though 
the time should be utilised in preparing for the busy season not far distant. 
Supplies of clean pots and materials for compost should be got in and pre- 
pared ready, so that when the time for potting arrives the work may be 
done as expeditiously as possible. Some hints on this subject were given 
last month. 
Seedlings of all kinds will show an increased rate of a. os aa 
lengthen and the amount of sunlight increases, and any that require pot- 
ting on and are showing increased root action may be shifted into a size 
larger pot. The old compost need not be removed unless any should 
appear unhealthy. Seedlings generally require less rest in the dull season _ 
and as the object is to get them large enough to — 
than established plants,
