step in their cultivation is to place them in the green¬ 
house best suited in temperature and moisture to 
properly develop them. Some years ago a shipment 
of plants was received by an amateur collector from 
South America. They had been floated down a 
river on a raft over two thousand miles, passing 
through two revolutions en route, were shipped to 
New York, thence to the collector, and flowered the 
next season. 
It is not advisable to crowd the plants in the green¬ 
house, and cleanliness is 
a great point to be ob¬ 
served. 
Some of the insect 
pests that infest the 
plants are wood-lice, 
slugs and the common 
house-fly. The Cattleya 
fly found on freshly im¬ 
ported plants is a much 
dreaded insect; its larva 
is deposited in the center 
of the young growth, and 
its presence is detected 
when the young growth 
about an inch high be¬ 
comes abnormally thick 
at the base and tapers to 
a point; the growth mak¬ 
ing but little progress. 
The only method of ex¬ 
termination is to cut out 
the infested young growth 
and destroy it. Too much 
moisture in the orchid

house causes damp root, while, 
on the other hand, if allowed 
to get too dry the plants are 
subject to dry rot. A plant 
just starting its growth will 
require very little water, just 
enough to keep the bulbs 
from shriveling; as the growth 
develops, gradually increase 
watering; when the bulb has 
matured, watering should 
cease to allow the bulb to 
ripen. When the flower buds 
appear the plant should receive 
plenty of water, but when it 
has ceased blossoming it 
should be given a season of 
rest. 
Beginning with the winter 
months the Cattleya Percival- 
lana and the C. Tnance are to 
be found in bloom. The Per- 
civaliana is called the Christ¬ 
mas orchid because it blooms at that time and makes 
a handsome decoration for the table during the holi¬ 
day season. The sepals and petals are white with 
purple throat veined with an unusually rich shade 
of yellow. 
Cattleya Tnance blooms during the months of 
December, January and February; it is pure white, 
and in pink ranging from the most delicate to a 
deep rose.
