140 THE ORCHID REVIEW. (May, Igrs. 
winter quarters ; with mild weather they are soon at home, and all through 
the summer they enjoy the extra shade.and the moist airy atmosphere as 
much as any plant in the house. After removal to the Cool house it is 
advisable to keep the plants for several weeks a trifle drier at the root than 
they have been in the warmer division, 
MILTONIA VEXILLARIA and several of its beautiful hybrids will now be 
sending up their flower spikes, and ought to be making from the base of the 
young growths plenty of new roots to support the flowers. Of these roots 
woodlice are extremely fond, and if not trapped and killed will quickly eat - 
the point of every one immediately it becomes visible. M. Reezlii, when 
well cultivated, is a beautiful Orchid, and the flowers are strongly rose- 
scented. It requires more warmth than any of the others. During winter 
the plant succeeds best on the shady side of the East Indian house, but 
through the summer the Intermediate house is the best place for it. Being 
a compact-rooting plant it should not be over-potted, as the roots like to 
cling to the sides of the pot, and when well established will enjoy an 
almost unlimited supply of water. 
MASDEVALLIas.—The white Masdevallia tovarensis may now be placed 
in the Cool house, if well established, but those plants that have been 
recently repotted should be kept in the warmer division for several weeks 
longer. All the Chimzroid Masdevallias, as M. Chimera, bella, Wallisii. 
Backhouseana, and nycterina will now do suspended in the Cool house, 
As these plants pass their flowers in a downward direction, like Stanhopeas, 
they should never be grown in pots, or many of their flowers would be 
destroyed. Put them in shallow baskets made of teak rods, placed wide 
apart ; use no crocks, and only osmunda fibre to root in. They must be 
kept moist the whole year round, as dryness at the root or in the air is bad 
for them; lightly spray their foliage every day. 
STIPPLING THE ROOF GLass.—Assuming that the cold dull weather is 
practically at an end, we may now reasonably expect plenty of warm sun- 
shine, which will be beneficial to the plants in every way. For several 
years past I have found it advantageous, at this time of the year, to have 
the roof glass of nearly all the houses stippled outside, the exceptions being 
the Dendrobium and Mexican houses. For the warmer houses I used @ 
mixture of white lead and paraffin, adding a little clear varnish to make it 
adhere firmly to the glass. The stippling should be done whilst the sun is 
shining full upon the glass, so that the mixture may dry on as quickly as 
possible. Clean the glass thoroughly beforehand, and see that no dirt is 
present where the glass overlaps, otherwise the mixture will block up the 
spaces, and make the roof air tight. Put the stippling mixture on these 
Warm houses as thinly as possible, and by the middle of the summer 4 
considerable portion of it will be worn off, thereby gradually accustoming
