300 THE ORCHID REVIEW. [OcroBEr, 1908. 
house, or if a flowering house can be spared they will keep better still, and 
well repay the trouble of removing them. Then the Cattleyas, Leelias, 
Oncidiums, and anything else that happens to be in flower, will make a very 
pretty group, and take off the flatness of the Cypripediums. When there 
are only Cypripediums to group they take a lot of arranging to make an 
effective group, but a few Cattleyas or Oncidiums for a background makes 
it very effective. When a lot of plants are in flower together we find it 
better to keep one house for them, even if we have to change a lot of plants, 
and put some in houses not used for them in their growing season. It does 
not keep all the houses on the dry side while a plant or two are in flower, 
and the plants can all be treated as usual, while the flowering house can be 
kept at 55° to 60°, which temperature will be found to suit almost every- 
thing just while it is in bloom, and not so much moisture used, although 
the plants should not be allowed to get dry at the roots. 
The Cypripedium houses should be kept at a nice growing temperature, 
and ample moisture used, even during the dull weather. Where a mixed 
lot are grown together 65° will suit all varieties, and where C. insigne, 
Spicerianum, Charlesworthii and their hybrids can be grown in a separate 
house 55° to 65° will suit them. C. bellatulum, x aureum, xX Euryades, 
x Thalia, X Minos, and most Fairrieanum hybrids like a slightly higher 
temperature, 60° to 70°. If a plant is not growing well, I find it a good 
plan to try it warmer or cooler, no matter what it is supposed to grow at, 
till you get the right temperature for it, and let those laugh who like so 
long as it is growing and flowering well. 
CALANTHEs will be pushing up their flower spikes, and should be kept 
moist at the roots until the spikes are fully developed, when they can be 
gradually dried off. A little manure water will assist them to form good 
spikes, and also make the flowers a brighter colour. They should be kept 
as near the light as possible, to help them to form stout spikes, then the 
flowers will last much longer, and it will also help to ripen the bulbs. 
Pleiones will also be pushing up their flower buds, and will need similar 
treatment, and should be kept in a temperature of 60° to develop their 
flowers properly. 
CATTLEYAS AND Laias of the autumn-flowering section will soon make 
a fine display. Plants that are pushing up their spikes should have a 
liberal supply of water at the roots, and should be staged in a light position 
in the house. In foggy weather we find we do not lose our buds if the 
temperatures are raised 5°, and plenty of moisture kept in the house, as 
the moisture fills up the crevices and keeps the fog out. Working on this 
principle we have not lost our Lelia anceps buds for several years, as We 
used to do when keeping the houses dry. Slugs and cockroaches must be 
trapped, or they will soon spoil a spike. Lettuce leaves will soon clear out
