stance, and they last much longer, either on the plants or when cut, and 
the bulbs do not shrivel after flowering. A little more care is then needed 
in watering, and if they are freely syringed they will not require much 
water applied direct at the roots. 
_ CAaATTLEYA TrIANz.—As the plants of this species pass out of flower they 
should be kept rather drier until the young roots commence to push from 
the base of the bulb, when any that need repotting should be done, before 
the roots get long, as then there is no danger of breaking the young roots 
and thus giving a check to the plant. Newly-potted plants should be placed 
at the warmest end of the house, where they can have extra moisture, but if 
this cannot be done the plant stove will suit them to perfection, as they seem 
to enjoy the heat and moisture of a stove house until they get established, 
when they can be moved to slightly cooler quarters. A little extra attention 
after repotting is well repaid at the end of the season with fine bulbs and 
sheathes. Osmunda fibre with about one-third moss makes a good mixture 
for Cattleyas, as they root well in it and throw good flowers. Keep the 
plant on a level with the rim of the pot, as then the roots have a much 
better chance of getting to the compost than when raised much above the 
pot ; it also prevents the roots being broken when re-staging or packing for 
exhibition, and woodlice, cockroaches, &c., cannot eat the roots off. We 
find treacle and arsenic one of the best methods of ridding houses of cock 
roaches, woodlice, ants, and other pests which the Orchid grower has to 
contend with. A little of the mixture dropped on small pieces of glass soon 
clears them out. 
L#LIO-CATTLEYAS AND HYBRID CATTLEYAS.—Any of, the early 
flowering varieties which have passed out of flower will require much the 
Same treatment as that advised for C. Triane. Plants that are getting over 
the side of the pots will be better repotted. Clean off all old material, and 
temove any old bulbs that are of no use to the plant, leaving three or four 
young bulbs. The old bulbs can be propagated if desired, provided of 
course there is a dormant eye. Specimen plants that have gone bare in the 
centre should be pulled apart, and re-made if desired, or potted into single 
pots. They look much better without the old bulbs, and grow stronger if a 
little extra care is taken after repotting. 
CLOGYNE CRISTATA.—This species, with its varieties, will soon require 
re-potting or top-dressing, the former being preferable for plants that are 
very crowded. They do well potted in the Cattleya mixture. Any that 
only require top-dressing should have as much of the old material picked 
out as possible, and then be re-surfaced and pegged down, SO that all the 
young roots can get to the compost. I do not think there is any Orchid 
which gets more ill-treatment than this Coelogyne. One sees it grown in all 
Sorts of corners ; stove, vinery, greenhouse, in fact any out-of-the-way place
