Cattleya House. They should have well-drained pots or pans, and over 
the drainage should be placed a good layer of rough moss, to prevent 
the fine particles of soil clogging it up. The soil used may consist of 
two parts lumpy peat, two parts turfy loam, with the addition of a little 
moss, and sufficient coarse sand or finely broken crocks to render the 
compost porous. For a few weeks after potting give little water, so as. 
to allow the new roots to enter the fresh soil; afterwards, as growth 
proceeds, a good supply may be given. Spraying is also very beneficial,. 
and an aid in keeping them free from insect pests. 
Stanhopeas are not very popular Orchids, yet where room can be found 
for them a few members of the genus should be grown, for the sake of their 
peculiar wax-like flowers. They should be grown in baskets—rather shallow 
—without any crocks or other hard substances at the bottom, as the flower 
scapes usually take a downward course, and oftentimes go straight through 
the basket. A small portion of fibrous peat and moss is all that is needed 
for them to root into, and excepting when in full growth very little moisture 
is required other than that obtained from the atmosphere. Those whose 
baskets have become decayed, or are too small, may be given new ones this 
month. They do best when suspended from the roof, in a rather shady 
part of the East Indian House. The above remarks also apply to that 
curious genus Coryanthes. 
-'Diacrium bicornutum is certainly a very handsome species, though 
- from a cultural point of view it is far from satisfactory. It has cylindrical 
bulbs, which are hollow, like those of Schomburgkia tibicinis, and on 
this account will not stand a long period of drought. It has just done 
flowering, and a short period of inactivity should ensue prior to new 
growths appearing. This species thrives best in baskets almost filled with 
crocks and just surfaced with moss. The baskets should be suspended 
in the warmest and lightest structure at command, and during the growing 
season given copious supplies of water daily. When the growths are 
completed the supply should be gradually diminished, though they should 
not be kept dry for long together, or the bulbs will shrivel beyond recovery. 
We can safely assume that fire-heat will no longer be required in 
the Cool and Intermediate Houses, and given typical summer weather,. 
very little will be needed in the other houses, though the fires should 
always be kept in, and a gentle circulation of heat maintained in the 
pipes of the East Indian Honse. It should also be employed at night 
in the Cattleya House, to drive away any surplus moisture, and also. 
that more air may be admitted through the bottom ventilators. Plants. 
in bloom should be kept moderately dry, excepting where root action 
is vigorous, as will probably be the case with such species as Cattleya 
Warscewiczii, Warneri, Gaskelliana, and Schilleriana.
