si CALENDAR OF OPERATIONS FOR JUNE.

Hybridising Department. 
|" the weather is seasonable very little fire heat will now be needed, and 
it is advisable to take advantage of this opportunity to overhaul the 
heating apparatus, and make good any defects in the system. The 
temperatures must be carefully regulated, and a slight increase will be 
beneficial during hot and sunny weather in all the Warm divisions. 
Ventilation and shading go together, and must be used in a way that will 
prevent excessive fluctuations in the temperatures. A moist buoyant 
atmosphere should be the rule in every department, and the houses must 
be damped down whenever they are dry, while the sprayer can be freely 
used among the seedlings and cool-growing Orchids. 
A collection of Orchids is always interesting, but especially so at this time 
of year when so many are flowering, and others are making their season's 
growth. Among the latter are the Calanthes, and all those that are rooting 
freely may be afforded liberal supplies of water, and the same remarks 
apply to the pretty Epidendrum vitellinum. Cattleya Warscewiczii call 
be given water more copiously after this date, and a few of the earliest 
plants will be producing their flower-sheaths. Any that do not bloom 
should be repotted, when they commence to root from the current 
pseudobulb, in a mixture of osmunda and Az fibre. C. Mossiz and C. 
Mendelii, as they pass the flowering stage, should be looked overt to 
ascertain if additional pot room or new material is needed, and if so the 
same kind of compost can be used. For a few weeks afterwards careful 
watering is necessary, and, until well-rooted, a little extra shade may be 
employed, or some of the back leaves may turn yellow and eventually have 
to be removed. The winter-flowering Cypripediums are making rapid 
growth, and will need ample supplies of water at the root, while an over- 
head spraying on bright days will be of considerable benefit. ae 
TuHuntias.—A few of the Thunias are pushing up their flower scapes 
and may be given alternate waterings with weak liquid cow manure. As 
the blooms expand they can be removed to a cooler and drier house, where 
the display will be prolonged. Miltonia vexillaria with its varieties, that 
make such a fine show at this season, ought not to be overdone with 
moisture at the root, and when the spikes are removed the plants should be 
slightly rested in the Cool house, and watered sparingly until the new 
growths begin to root, when any repotting can be carried out. 
STANHOPEAS are not grown so much as they deserve, and, owing 10 
their mode of flowering, are well adapted for suspending from the roof of 
the Warm or Cattleya division. All should be grown in teak-wood baskets
