flowers are required in quantity too many cannot be included. 
Stage room is often limited, and thus as many cannot be accommo¬ 
dated as otherwise would be the case. They do well, however, in 
small baskets, and by suspending them from the roof it is possible to 
grow fully double the quantity without crowding those grown in 
pots or discarding other useful plants. 
Orchids in February. 
The following Orchids are now in bloom lat Messrs. John 
Laing & Son’s, Stanstead Park Nurseries, Forest Hill:—Angraecum 
sesquipedale, Coelogyne cristata, Cattleya Trian®, Cymbidium 
Lowianum ; Cypripediums Boxalli, callosum, Harrisianum, insigne, 
Sedeni (hybrid), cardinale, venustum, and villosum ; Dendrobiuras 
Ainsworthi (hybrid), crassinode, Barberianum, heterocarpum 
the summer months they require plenty of water, and a good 
position near the glass where they have plenty of light without 
direct sunshine. One matter of great importance is to keep the 
atmosphere always moist, with plenty of fresh air about them, 
but take great care the temperature does not fall too low in con¬ 
sequence of too abundant moisture, which would be injurious. 
During the winter they should be kept dryer, also in spring until 
the flower spikes appear, when water should be given liberally and 
continued until the summer growth is completed. Many Orchids 
are killed by high temperatures and dry atmospheres, which bring 
all sorts of insects, and the plants are often injured still more 
in trying to eradicate the pests, especially in the warm section. 
Hardeners have great difficulty in growing cool Orchids, because 
the houses usually are not adapted for them. I have often seen

(aureum), Jamesianum (Moulmein), moschatum, nobile pendulum, 
Pierardi, Wardianum, and Wardianum splendens ; Dendrochilum 
filiforme, Laelia anceps, Odontoglossums Alexandra (crispum 
Blunti), Pescatorei, and pulchellum ; Oncidiums barbatum and 
ornithorhynchum, Phaius grandifolius, Phalaenopsis amabilis and 
Schilleriana, and Sophronitis grandiflora. 
Odontoglossums. 
For purposes of cultivation Odontoglossums should be divided 
into two sections or groups ; the warm section species require an 
intermediate house, the temperature 50° to 55° in winter, with 10° 
higher in summer when they are making their growth. The 
principal species requiring warm treatment are Odontoglossum 
grande, O. Insleayi, 0. blandum, O. bictonense, O. bictonense 
album, 0. Harryanum, O. vexillarium and their varieties, O. cir- 
rhosum, and 0. citrosmum. When making their growth during 
Cattleyas, Vandas, Oncidiums, and Odontoglossums all in one house 
growing or struggling together ; eventually it is wondered why the 
Odontoglossums are looking so bad, for they are sure to be the 
first to suffer in a mixed collection. 
Now I will say a few words on the cool section. I need only 
name such as 6. Alexandras and its varieties, O. triumphans, 
0. Edwardi, 0. Pescatorei, O. Rossi majus, O. Sanderianum, 0. odo- 
ratum, O. nebulosum, O. hebraicum, and 0. Wilckeanum. These 
cool Odontoglossums are found at great elevations, and therefore 
are found in very cool situations amidst dense moisture, and con¬ 
sequently require little artificial heat; in fact, the greatest difficulty 
is keeping them cool enough in our summers. Like the warm 
section they require all the light possible without direct sunshine, 
and the best house is one that faces the north, so that you do 
not have to shade them very much. In midsummer, shade is, 
however, indispensable, and you cannot throw too much water
