green tinge of health. Not only have the plants had the direct sun of a 
south aspect to face, but, “tell in not in Gath,” in the summer, early every 
morning, they have been sprinkled overhead with a hose-pipe attached to 
the ordinary tap! On hot days the ashes on the staging and among the 
pots were sprinkled with water two or three times. I may be wrong, but my 
opinion is that the sprinkling of the plants and the amount of water thrown 
around them generally created a film of vapour on the glass that. was 
sufficient to prevent the leaves being scalded. Was it not Louis Forget, 
Messrs. Sanders’ famous collector, who, in describing the discovery of 
the superb Lelia Gouldiana, stated that after climbing for days from the 
hot plains he found this lovely flower in the early morning covered with 
hoar frost; and I suppose a few hours later it would be scorching in the 
sunshine. 
It may be sound for the professional gardener, who can put the blinds 
on or take them off according to the power of the sun, but the average 
amateur cannot. I am of the opinion that the admission of air is also a 
great factor. Strange to say, we never admit air summer or winter, and we 
are pretty liberal with water, when conditions are at all favourable, conse- 
quently, except on very cold nights—and it is cold up here—we always have 
that delightful humid atmosphere which is probably the secret of our 
success. 
Let me confess again, that the few unfortunate Odontoglossums and 
Oncidiums that have had the misfortune to find a temporary home in our 
collection do not appreciate the methods, and they show their resentment 
by dying. But the Cypripediums, Lelias, Leliocattleyas and Cymbidiums, 
though they are at the end of the house that in the afternoon is shaded by 
a tree, grow and bloom pretty much like weeds. 
AMATEUR'S PAGE, 
Leaves Decaying.—*‘‘I have much trouble with the leaves of my Ccelogyne 
cristata, many of which are disfigured by wet patches that ultimately turn 
to decay and need to be removed by trimming with scissors.” 
This condition of the foliage is brought about by an unsuitable atmos- 
phere during the winter. Ccelogyne cristata grows well in a cool greenhouse 
during the summer time, as well as in the early autumn months, but it 
requires removing to an intermediate house for the winter. This does not 
mean that a higher temperature is required during the dull months, but 
merely a continuation of the same temperature that existed in the cool 
house during the late summer and early autumn months, and this is 
generally to be found in what is termed the intermediate houses. With a 
minimum temperature of 55-60 degrees no difficulty should be experienced
