i CALENDAR OF OPERATIONS FOR AUGUST. ; 
Hybridising Department. 
URING the present month the general growing conditions should be 
maintained in each division, and to achieve this object it will be 
necessary to devote considerable time to the ventilation, shading, judicious 
watering, and damping down in every house. Success will largely depend 
upon how these details are carried out, and cleanliness is equally 
important. At this period of the year some plants will have completed 
their season’s growth, while others will be approaching that stage. Where 
possible they should be placed in another house, where the atmosphere is 
slightly drier, and the shading is not quite so heavy, but care must be taken 
that they do not suffer from drought. If this idea cannot be carried out 
they may be arranged in a batch and treated accordingly. 
CALANTHES.—From now until the leaves begin to decay the Calanthes 
should be afforded copious waterings, and if space has been left for top- 
dressing, the present is a good time to do it. Some growers give all 
occasional watering with weak liquid cow manure and soot, but this 
should not be permitted until root action is vigorous, and the new 
pseudobulb is formed. The leaves of well-grown Calanthes take up @ 
lot of space, but they must be allowed plenty of room to develop. 
CYMBIDIUMS that were repotted early in the year will take water more 
frequently, and any that need fresh rooting material may be given attention. 
Among the latter will be C. Lowianum, C. eburneum, and others that were 
not disturbed earlier in the year. 
CATTLEYAS AND ALLIES.—Cattleya labiata is making up some fine 
pseudobulbs, and water must be given generously till the spikes a 
removed. C. Gaskelliana and some of the long-bulbed sections will be 
flowering. The various forms of Lelia anceps are well-rooted, and a ae 
of the early plants will be developing their flower scapes in conjunction 
with the new growth. The shading should be removed earlier in the day, 
and the plants ought not to become dry at the base. 
Many of the small Bulbophyllums, Cirrhopetalums, and the other 
miniature botanical Orchids can be either top-dressed or repotted as they 
Pass out of flower. They are usually suspended from the roof, where the 
atmosphere is warm and moist, and at no time ought they to becom 
excessively dry at the root. 
DENDROBIUMS belonging to the nobile group will begin to complet? 
their season’s growth, and when the terminal leaf appears the resting pe 
can be commenced by giving the plants a lighter and more airy pos 
but a fair quantity of water will still be necessary.
