THE ORCHID REVIEW. 218 
shading should be taken off early in the afternoon, and a high temperature 
induced by closing the ventilators for a few hours, always opening the 
bottom ones again at night, so that all superfluous moisture may be 
dispelled. L. autumnalis, albida, furfuracea, and Gouldiana require the 
same treatment, excepting that they should not be syringed sufficiently 
heavy to allow the water to lodge in the undeveloped growths, for if it does, 
and a change of weather from fine to dull or wet takes place, the growths 
are apt to damp off. 
We grow most of our Dendrobium nobile in the Cattleya house, as there 
we obtain far better results than from those grown in the stove. The 
reason is, I think, that the former do not commence to grow so early in the 
year, when the weather is so changeable, and therefore the growths 
produced are not subjected to such fluctuations of heat and light, and the 
progress made now is of a more sturdy and lasting character. They are 
suspended from the apex of the roof, where during the day-time the 
temperature is high, and yet is tempered by a free-circulating air. D. X 
Ainsworthii also does well in this house. The majority of the Dendrobes 
are growing now, and all of those that are rooting freely must not be 
allowed to suffer from dryness at the root. If there should be any plants of 
D. Wardianum, crassinode, or nobile that have finished their leaf 
development, they should be removed to a cooler and more airy situation, 
but be still supplied with the requisite quantity of water. A vinery from 
which the fruit has been cut is an excellent place for them to mature and 
ripen their growths. 
Aérides, with few exceptions, are summer flowering plants, and there are 
few persons but will admit that they are exceedingly pretty and highly 
interesting Orchids when cultivated successfully ; yet, for some unaccount- 
able reason, they are entirely out of the running now, and were a person to 
give two hundred guineas for an Aérides he would, I am afraid, be con- 
sidered in a state of non compos mentis. However, the lack of public favour 
in no wise detracts from the beauty of their flowers, which in several 
instances emit a most delightful perfume, and I am sure if some of our 
clever Orchid men were to take them in hand again, and prove that they 
are manageable subjects, the present generation of Orchid amateurs would 
be induced to invest their money in them, and hence secure their importa- 
tion in quantity again—that is, if they are to be found. No Orchid is much 
easier to grow during the summer than the majority of these, but when 
winter comes most of us are baffled. Now is the time to think about what 
we have te contend with in the winter time, and instead of growing these 
in a hot, close atmosphere, thus inducing growth of a weak and flimsy 
nature, we should try by every means at our disposal to get the plants to 
build up good, strong, and well-matured leaves, that will pass unscathed
