employed. Permanent shading painted on the glass is bad, because it cuts 
off the light in dull weather when its presence is beneficial. Lath 
roller blinds are the most suitable, and those on the roof should run on 
supports well above the glass, so as to allow a free current of air beneath. 
These blinds must be let down whenever the sun is powerful enough to 
injure the foliage, from spring to autumn. Next comes the provision for 
watering and damping down, and for the former a good rain-water tank 
within the house is almost indispensable, because the water is then of about 
the same temperature as the atmosphere, and soft water only should be 
used. Hard water might be used for damping the floors, walls, &c., in time 
of scarcity. These arrangements being made, the grower will be able to 
control the temperature and moisture of the atmosphere at all seasons in 
accordance with the requirements of the plants. 
Now comes the provision of a suitable staging, but first we may consider 
what are the best plants to grow, and here one has to be guided largely by 
circumstances, though the question of individual tastes also comes in. A 
single house will generally be a Cool house, but if it can be divided bya 
glass partition, and the piping arranged so that one half can be kept a few 
degrees warmer than the other it will give a wider choice of varieties. It is 
a good plan to commence with established plants if possible, as there is 
the greater probability of their continuing to progress, and it is well not to 
attempt too many kinds at first. 
Odontoglossums may be mentioned first, as the most popular of Cool 
house Orchids, and the most suitable kinds will include O. crispum, 
Pescatorei, triumphans, luteo-purpureum, Hallii, cirrhosum, Rossii, and 
Cervantesii, any or all of them, and a few others might easily be included. 
Cypripediums should include C. insigne and any of its varieties that can be 
secured, C. Spicerianum, Charlesworthii, and villosum, with the hybrids C- 
sum. Masdevallias will include M. Veitchiana and 
X nitens and C. x Leeanu 
M. coccinea varieties, and Oncidiums, O. tigrinum, O. macranthum, and O. 
erown kinds include the brilliant 
varicosum. A few other showy and easily-g 
Sophronitis grandiflora, Epidendrum vitellinum, Ada aurantiaca, Ccelogyne 
cristata, Lelia pumila and L. Dayana, Anguloa Clowesil, Lycaste 
Skinneri’ and L. cruenta, Cymbidium Lowianum, Zygopetalum inter- 
and Dendrobium Jamesianum. Such a 
medium, Maxillaria grandiflora, : 
a good succession, too, if 
selection will yield a fine display of bloom, and | 
fairly treated. With the warmer division also available the following others 
may be included:—Cattleya labiata, Mossie, Mendelii, Loddigesii, 
intermedia, Skinneri, and citrina, Lelia purpurata, anceps and autumnalis, 
a few of the Lelio-cattleyas, Cymbidium eburneum, Miltonia vexillaria, 
ha and xantholeuca, and 
Dendrobium thyrsiflorum, nobile and Wardianum, A.
