266 THE ORCHID REVIEW. [SEPTEMBER, IQTIe 
CALENDAR OF OPERATIONS FOR SEPTEMBER. 
By J. T. BARKER, The West Hill, Hessle, E. Yorks. 
SHOULD the delightful weather which we have now enjoyed for some time 
continue, the conditions advised in previous Calendars may be continued, 
but should it change from the bright sunshine to damp and colder conditions, 
then the temperatures may be reduced in all departments by a few degrees, 
proportionate to the prevailing conditions of the weather outside. 
Shading must still be used, but used with discretion, and in no case 
more than is absolutely necessary to prevent the plants from scorching, as 
by these means it should be our aim to build up and strengthen our plants, 
so that they may be better able to withstand the winter season which is 
before them. 
VENTILATE as liberally as possible on all favourable occasions, as air at 
this season is as essential as light in the important factor of ripening the 
newly-made growths. 
DAMPING DOWN may be done less frequently, but, at the same time, a 
nice moist genial temperature must be maintained, and a hot, dry 
atmosphere must be guarded against at all times. 
CooL HoUsE.—The Cool house must still be kept as low as possible, both 
night and day. To the inmates of this department, where the houses lay at 
all bright and dry, the weather conditions recently have been unfavourable, 
and undoubtedly many plants will have suffered in some way or other from 
the continued sunshine. 
Warm HouseEs.—In all the other departments the plants have enjoyed 
the conditions, and have made wonderful progress, and apparently have 
revelled in the heat and light. The temperatures of these departments must 
have attention, especially during a spell of cold damp weather, which 
undoubtedly we shall have before the month is out. A little extra fire heat 
at this season (even if we have to use a little more ventilation to counteract 
it) is much better than a low cold atmosphere, which should be guarded 
against in every case. 
WATERING at this season must be done with the greatest discretion, 
always bearing in mind that it is much easier to get a plant, or rather the 
compost in which it is growing, wet than it is to get itdry again. Likewise 
much harm can be done by the other extreme of over-dryness, and the 
happy medium is what we should aim at. No plant should have water 
applied to it unless it absolutely requires it, neither should it suffer for the 
want of it. Many plants, even of the same species grown under the same 
conditions, differ very largely in the amount of moisture they take up, and 
to be successful every cultivator must know his plants. 
We have now passed the best part of the summer, and must prepare for
