22 THE ORCHID REVIEW. 
CCELOGYNE CRISTATA ALBA. 
It may be interesting to note that at the sale of Mr. Lee’s Orchids, 
at Leatherhead, I purchased a large plant of Ccelogyne cristata alba, 
which used to shrivel up to such a degree that I thought it would never 
recover. I had the plant divided and repotted, still with the same result. 
Last year it was again divided into six eight-inch pans, four of which 
were hung up close to the glass in the intermediate house, and the other 
two placed in their old position on the staging, Those which were hung 
up have scarcely shrivelled at all, and are now very fine fat bulbs and 
showing for bloom very well indeed, while those that are on the staging 
resemble Pharaoh’s lean kine. Ergo, hang the plants near the glass, and 
they will do as well as the ordinary variety—that is my experience.

CALENDAR OF OPERATIONS FOR JANUARY. 
By H. A. BurRBERRY, Highbury, Moor Green, Birmingham. 
IN commencing the Calendar of Operations for the present year, I desire 
to thank several correspondents for their kind and encouraging remarks, and 
to say that although in treating of cultural matters it will be necessary to 
travel over a good deal of old ground, I shall endeavour to introduce new 
matter as much as possible, so as to interest both new and old readers. 
The following temperatures should be maintained during the present 
month :— 
CooL, Hovuse.—Day, 50° to 55°, with sun, 60°; night, 50°, morning, 45° 
to 50°. 
CATTLEYA, INTERMEDIATE AND MExIcAN Hovusgs.—Day, 60° to 65° 
with sun, 68°; night, 58° to 60°; morning, 55° to 58°. 
INDIAN ee 65° to 70°, with sun, 75°; night, 65°; meres 
60° to 65° 
The nearer these figures are maintained the better aor the general 
welfare of the plants. 
Let the plants in all departments have as Much light as possible, for at 
this dull time, if they are too far away from the glass, they become drawn 
and weakly. The air can also circulate more freely round them when 
suspended or raised up on inverted flower-pots. 
Tue Coot Hovuse.—The principal work in this department will consist 
in keeping the plants clean, in providing 4 suitable temperature and 
atmosphere, and in very carefully watering the plants. To dislodge yellow 
thrip, which is perhaps the greatest enemy to Odontoglossums, working 
much havoc with the young growths, I have found no better remedy than 
Fowler's tobacco powder. I found this article so valuable that I always
