212 THE ORCHID REVIEW. 
corridor, which is kept at a warm greenhouse temperature, where they grow 
equally as freely, and have made for the past few weeks a good show of 
bloom. If repotting is required, we do it this month. Before a shift is 
necessary the pot should become pretty full of roots, when it may be given 
a larger sized pot, giving it a similar compost, and potting it in the same 
manner as you would a chrysanthemum. Sobralias are frequently difficult 
to establish, but when this is once done, they give but little trouble. Our 
plants of Cattleya Rex, C. Lawrenceana, C. Dowiana aurea, and C. inter- 
media are grown in a house having a trifle more warmth than the other 
Cattleyas. The last-named should be repotted this month, as should also 
C. Lawrenceana, if not already done. The beautiful C. x Parthenia, C. X 
calummata, and C. X Brymeriana should likewise have attention in this 
respect without any delay. C. x Chamberlainiana seems to have rather a 
weak constitution, probably inherited from its parent, C. Dowiana aurea. 
Our plant occupies a favourite position on a shelf, and is gradually, though 
slowly, growing more robust. 
Tue East InpiAn House, containing such plants as the warm Cypri- 
pediums, Saccolabiums, Aérides, Angrzecums, Miltonias Roezlii and Wars- 
cewiczii, Phaius tuberculosus, Pescatoreas, Phalznopsis, &c., is not given 
quite so much light as the Cattleya house, nor ventilated so freely, but is 
damped down quite as often. Most of the resurfaceing and repotting has 
likewise been done here. A good deal of work and attention is, however, 
still necessary to keep everything clean and free from parasites. 
THE SHOW House is, perhaps, of more real service during the summer 
than at any other time of year. A suitable temperature is maintained to 
keep the blooms fresh and free from spots, which is caused by dampness; 
but the temperature is not kept so dry as to injure the health of the plants 
in any way. It is mostly during the night that the delicate flowers become 
spoiled. Frequently during the summer, when the nights are warm, fire- 
heat in the growing houses is dispensed with, with great advantage to the 
plants ; but at this time flowers are often disfigured and rendered useless. 
In the Show house a little warmth in the pipes is therefore maintained, and 
a very little is sufficient to prevent spotting. A charming effect is produced 
by arranging the plants in such a house with Adiantum cuneatum, and the 
flowers will remain perfect until a for cutting. This house, too, is 
rather more heavily shaded. 
THE CooL House is simply kept as cold as possible, both day and night, 
the thermometer not being consulted. Much moisture is distributed on 
the floors, stages, and elsewhere. I think very little indeed is gained by 
syringing the plants over-head, and therefore rarely practice it, unless the 
weather is very dry and parching. The atmosphere may, and should be, 
kept as saturated with moisture as the abundance of air which should con- 
tinually be on will admit of. If there are not enough ventilators in this
