236 THE ORCHID REVIEW. [AuGUST, 1911s 
CALENDAR OF OPERATIONS FOR AUGUST. 
By J. T. BarKER, THE WEsT HILt, HEss_Le, E. YORKS. 
‘THe temperatures and the growing conditions must be maintained as last 
month, and everything must be done to encourage the plants that are in 
full growth to develop as speedily as possible. The recent hot and bright 
-weather has been all that could be desired for the inmates of the Warm 
-and Intermediate houses. 
SHADING and watering must have the closest attention, or else very 
‘serious results may be the consequence. Plants may be very seriously 
injured if the sun is allowed to shine upon them for any length of time, 
especially when the house is heavily charged with moisture (which it should . 
‘be during such weather as we have been having lately). The blinds should 
‘not be allowed to be down one minute more than is necessary, as the plants 
should be inured to all the light possible, but not the direct rays of the sun. 
WATERING must be attended to, as no plant must be allowed to suffer 
for the want of water at this season; many plants, I believe, lose their 
roots by being allowed to get too dry during hot weather, when the pots 
and pans in which they are growing absorb and evaporate a great deal of 
‘moisture. Should the hot weather continue, spraying and syringing may 
‘be done once or twice every day, but should the weather be at all dull it 
must be done with discretion, and in no case must an excessive amount be 
allowed to remain in the centres of the young growths. 
VENTILATION.—A gocd circulation of air may be kept up to enable the 
plants to build up and solidify themselves, so that they may be thoroughly 
ripened before the winter months are upon us. 
CypripEpiums of the winter-flowering section, which were potted early 
in the year, as directed, will now have filled their pots with roots, and must 
have ample supplies of water, as I believe many cases of malformed flowers 
are caused by the plants being allowed to get dry at this season. 
DENDROBIUMS of the nobile section, towards the end of the month, 
must be gone through, and any that have completed their growths must be 
removed to cooler and drier quarters, but water must not be withheld, and 
in no case must the plants be allowed to shrivel. 
Coelogyne pandurata, and other varieties, as they pass out of flower, 
and are seen to be pushing roots from the young growth, may be repotted, 
should they require it. The compost recommended in previous numbers 
for the green-leaved Cypripediums will answer their requirements. 
CaTTLeEyas of the summer-flowering sections, as they are about to push 
roots, should be gone through, and any that have the compost at all 
sour, or likely to become so, before another year, should have attention 
and be repotted, as Iam thoroughly convinced that the state we often see,
