Where permanent shading has been used it should now be cleaned off, 
and everything done to secure for the plants the maximum amount of light. 
Plants should be raised as near to the glass as possible, by using inverted 
pots or by some other means, which also allows the air to circulate round 
them freely. Strong specimens are by this means maintained in health, 
and weekly ones have a chance to recover. With the exception of the 
Cool house the roller blinds should now be taken down, when dry, and 
stored away; unless they are required as a protection against cold in 
winter. On the Cool house they may still be needed for a few hours 
during bright sunny days. 
The Cool house should be ventilated freely, both night and day. Rather 
than close the ventilators, if the nights are cold, have a slight warmth 
in the hot-water pipes. If the weather is mild and no artificial warmth is 
required, once a day will most probably be often enough to damp down the 
surroundings, and let that be done during the forenoon. Should the nights 
be frosty, necessitating a little fire-heat, the atmosphere will dry more 
quickly, and damping down may be required twice a day. Much, however, 
depends upon the position and structure of the house. Most growers 
know that the majority of Cool-house Orchids like a moist atmosphere and 
detest a dry one, but a great mistake is sometimes made by keeping a 
stuffy stagnant atmosphere, although the thermometer may still register the 
desired degree. In such cases fungus or mildew supervenes, the tips of the 
leaves decay, and frequently a good deal of cutting and trimming up is 
required to give them a respectable appearance. 
Where Cattleyas and Mexican Orchids are grown no shade should now 
be given. Air should be admitted as freely as the outside conditions 
permit, and once a day (mornings) will suffice for damping down, unless a 
deal of fire-heat is required. Water now with a good deal of care and 
discretion, for as the days shorten and become darker much less moisture is 
needed to keep the plants plump and healthy. Avoid droughts, however, 
which produce starved-looking plants with shrivelled-up pseudobulbs, for 
such plants rarely fully recover. ; 
The above remarks apply equally well to other intermediate growing 
Orchids—such as the Oncidiums, Zygopetalums, Miltonias, Cynbidiums, 
&c., excepting that the majority of these, being continually 
Cypripidiums, 
ie : e water at the roots, though 
in a growing condition, will require a little mor 
with these also watering should be done carefully, for nothing whatever is |
