the dullseason by putting our plants into their winter quarters, and cleaning 
up generally. All houses should be thoroughly cleaned inside and out 
—glass, woodwork, walls, and staging. The plants, before being staged. 
in their winter quarters, should be thoroughly cleansed of all kinds of dirt 
and insect pests. Where it has been observed that particular plants do 
well in a particular position, it is always wise to continue it in that position. 
CYPRIPEDIUMS will now be pushing up their flower spikes, which should. 
be neatly tied to stakes to prevent them from twisting. Summer-flowering 
Cypripediums, as they pass out of bloom, may be repotted, should they 
require it, using a compost as previously recommended. 
DENDROBIUMS that have completed their growths should be removed to- 
the resting house, giving them just enough water to prevent shrivelling. D. 
Phalzenopsis Schroederianum and D. formosum will now be pushing up: 
their flower-spikes, and in many cases are well advanced, and should have all 
the light possible to enable them to open their flowers before the autumn fogs 
are upon us, as these have such a pernicious effect on these beautiful flowers. 
Evergreen Dendrobiums, such as D. thyrsiflorum, densiflorum, Farmeri, 
&c., are now fast completing their season’s growths. As soon as the shoots. 
have reached maturity a similar treatment should be afforded to that recom- 
mended for the deciduous species of this interesting class of plant. The 
rooting medium should not be allowed to become too dry for long together 
during the resting period, or irreparable damage may occur. 
CATTLEYAS, LALIAS, AND THEIR HYBRIDS.—Push on with the potting 
of these lovely plants as the new roots become active, as a sweet and clean. 
rooting medium is essential to their well-being. 
MitTonias.—Any plants of Miltonia vexillaria and M. Bleuana that 
were not done as recommended last month should, if they require repotting,. 
be done now, as soon as ever the young growths are seen to be pushing new 
roots. 
OpDoONTOGLOssUMS.—Push on with this section as fast as possible, and 
keep them well shaded until they get re-established in the new compost- 
The usual precautions must be taken with newly-potted plants. The plants 
may be carefully sprayed overhead once or twice a day, when the weather 
permits. Any back bulbs that are taken off to enable the plants to be placed. 
in a moderate-sized pot should be taken care of, as many of them, if 
placed in a box, on a layer of sphagnum moss, will produce new growths: 
and make nice plants within a twelve month. The box in which they are 
placed should be stood well up to the light in the house in which they have 
been grown. 
Cuysis.—C. aurea, C. bractescens, and other members of this family 
should be suspended at the warmer end of the Cattleya house, or in the 
warmer division of the plant stove, so as to enable the growths to finish
