several sizes, ready for use. Blocks, or rafts, may also 
be made of teak, or pieces of tree-fern will frequently 
answer equally well. A moist atmosphere is most de- 
sirable for all during the summer, or growing season, 
and, as a rule, plenty of water at the root. The amount 
of rest necessary varies considerably, and can only be 
properly apportioned by experience with different genera 
or species; some (as already remarked) are seldom com- 
pletely at rest. Heavy syringing is not recommended 
at any season: a very slight dewing over the plants 
may be advantageous in summer; but, further than 
this, the use of a syringe should be limited to dis- 
tributing water amongst the pots for moistening the 
atmosphere, Cleanliness amongst Orchids, in every 
respect, is one of the main roads to success. Dirt on 
the plants, or the pots, in the drainage, or even on the 
beds beneath, will soon produce an evil effect on the 
healthy appearance that should, and generally does, 
characterise Orchids receiving proper attention. 
Insecte, Fe. Orchids are subject to many insect pests, 
and to a much-dreaded disease called the“ spot.” This 
latter is considered to be encouraged, especially in winter, 
by a superabundance of moisture and by a stagnant atmo- 
sphere. White and Brown Scale, Mealy Bug, Yellow 
and Black Thrips, Red Spider, Yellow and Green Fly, 
are all included in the insect pests to the attacks of 
which the plants are at times liable. Sponging with 
weak soft soap or tobacco water is recommended for 
eradicating any of them: fumigating Orchids is a prac- 
tice not to be approved of, as it undoubtedly causes 
injury at times. Cockroaches, Slugs, and Snails, must 
also be included amongst the enemies of Orchids. 
ORCHIDIUM. A synonym of Calypso. 
-ORCHIS (the ancient name, from orchis, testiculus ; 
referring to the two oblong tuberous roots of some of the 
glands in a common pouch. Stem erect, herbaceous, 
leafy at the base. The few species worth cultivating 
thrive best in a deep rich soil; those which naturally 
prefer chalky soils should be planted in one of similar 
nature. They are very impatient of disturbance at the 
roots. Propagated by division. Transplanting should only 
be performed during the autumn months, when the growth 
of the young roots will have fully matured.
