the Cattleya house. Cypripedium insigne, C. Spicerianum, and many of 
their numerous hybrids, are now throwing up their blooms, and we shall 
soon be in the midst of the Cypripedium season again. The flowers should 
be neatly tied up to sticks. Sophronitis grandiflora is growing and pushing 
up its buds with the young growths, and should not be neglected at this 
season. The plants should be kept uniformly moist. 
WaTERING.—Much less watering all round will now be required. 
Plants that are developing their inflorescences must have sufficient for that 
purpose, but much less will be required when they have done flowering. 
The tissue of the pseudobulbs made during the summer will now be getting 
hard and woody, and will withstand more dryness at the root without 
shrivelling than it could have done some time ago. Even plants that are 
growing, such as Odontoglossum crispum, Lelia harpophylla, and others 
should be allowéd to dry out well before having a fresh supply. 
TEMPERATURES.—The temperatures given last month will be found a 
safe guide for this. Much more fire-heat will now naturally be necessary, 
but every advantage must be taken of the sun. Before October is out 
shading should be entirely dispensed with ; a little extra ventilation, to 
prevent any danger of scalding, will be better than having the blinds down 
with the ventilators closed. But guard against cold winds. 
The phenomenal heat with which August went out and September came 
in cannot be without its effect on Orchids. Following such a long spell of 
‘dry, sunny weather, and at a time when many plants had finished up their 
pseudobulbs, the result may be that some will be irritated into re-starting 
into growth. Where this has happened—and in the most normal of seasons 
it always does to some extent happen—I think it is best not to insist upon 
the growth coming along quickly, by giving extra warmth and water, but to 
treat such plants in exactly the same way as these which have not ‘Te- 
started. In some cases these premature breaks will grow and finish up ina 
very short time, while in others they grow slowly, and sometimes finish up 
quite small. Dendrobiums and Cattleyas are the two classes which are 
most liable to do this, but little if any harm ensues if they are not coddled 
in extra warmth. 
WasHinG THE FoLIAGE OF ORCHIDS.—Growers of plants know that 
cleanliness is of the utmost importance to successful cultivation, and now 
that most Orchids have finished their season’s growth the work of cleaning 
them should be proceeded with. All plants that have the foliage dirty 
Should be washed, but I am not a believer in washing for washing’s sake, or 
to keep men employed. Where there has been, or is, any kind of ame 
Pest—seale, red spider, mealy bug, green fly, ants—careful — 
bedone. F oliage may also become dirty through exudation from stn 
buds, syringing with chalky water, &c., when it will be necessary to clean
