of beauty either in vases or bouquets. The following is a list of varieties 
which may really be called Cool-house Orchids, i.e., those which may be 
grown all the year round in such a house as described :— 
Odontoglossum X Andersonianum and its varieties, O. bictoniense, 
O. blandum, O. cordatum, O. constrictum, O. coronarium, O X Coradinei, 
O. Cervantesii, O. cirrhosum, O. crispum, O. Edwardii, O. Hallii, O. X 
Humeanum (aspersum), O. luteopurpureum, O. nebulosum, O. Pescatorei, 
ramosissimum, O. retusum, O. Rossii, O. tripudians, O. triumphans, 
. Uro-Skinneri, and O. X Wilckeanum. 
Oncidium cheirophorum, O. concolor, O. cucullatum, O. excavatum, 
. Forbesii, O. Gardneri, O. macranthum, O. nubigenum, O. Phalznopsis, 
. serratum, O. tigrinum, and O. undulatum. 
Masdevallia bella, M. caudata (Shuttleworthii), M. Chimera and its 
varieties, M. coccinea and varieties, M. Houtteana, M. ignea, M. Roezlii, 
M. Schlimii, M. x Shuttryana, M. tovarensis, M. Veitchiana, M. 
Wageneriana, and M. Wallisii. 
Ada aurantiaca, Cochlioda rosea, C. Neetzliana, C. vulcanica, Cymbidium 
Lowianum, Cypripedium insigne, C. Boxallii, C. villosum, Dendrobium 
Jamesianum, Disa grandiflora, Epidendrum vitellinum, Maxillaria grandi- 
flora, Sophronitis grandiflora, Trichopilia fragrans, and others. 
Having made a selection from the above list, which will be sufficient to 
serve our purpose, the plants should next be disposed about the house in a 
satisfactory style. Thus at the back of the stage place the tallest growing 
plants, such as Cymbidium Lowianum, Oncidium macranthum, Odonto- 
glossum Edwardii, and such like; then in front place the moderate 
growing plants of Odontoglossum, intermixed with Ada aurantiaca, 
Oncidium cucullatum, the Cypripedes, and so on. In the coolest and 
moistest part of the house place the various Masdevallias, while the roof 
will be occupied with the dwarfest plants, such as Odontoglossum Rossii, 
O. Cervantesii, the brilliant scarlet Sophronitis grandiflora, Oncidium 
Forbesii, and the beautiful Oncidium concolor, to which the dwarfest 
plants of Masdevallias, such as M. caudata, and other like plants may be 
added. ; 
When furnished, the Cool house will be a thing of joy and beauty, full 
of interest even at times when the bloom is comparatively scarce. Do not 
expect your plants to do toé*much, either by flowering them too often, or 
making them carry their flowers too long, as many, especially among the 
Oncidiums, will flower themselves to death. Have duplicate plants, and 
flower them in alternate years. Another excellent plan is to cut the spike 
as soon as developed, and place it in a tube of water next to the plant, as it 
will last nearly as long as it would if not cut, and at the same time greatly 
relieve the plants. Orchids are fastidious. Often when they refuse to grow
