for all subsequent genera mentioned. First knock the plant carefully out 
of the old receptacle, remove all crocks, sour soil, decayed bulbs and leaves, 
and trim all dead roots. Then fill a fresh pot two-thirds full of clean 
broken crocks, and on these place the plant, carefully spreading out the 
roots and working in the suitable soil. Do not set the plant too low in the 
pot, but have the base of the bulbs on a level with the rim. Place the 
Orchid well to one side to allow for future growth. Remove all useless 
back bulbs, leaving three to support the new lead. For compost use 
moderately well-chopped osmunda and polypodium fibres in equal parts, 
with a few heads of living sphagnum moss and a handful of oak leaves. 
Use the whole in a slightly damp state. 
ONCIDIUMS. 
The method and soil needed in the repanning of these was given in full 
in the last volume, page 359. Oncidium Marshallianum should be 
suspended near the roof glass in an Orchid pan, and not repanned 
annually. Grow this and the other species suggested last month near 
the light. 
. TRICHOPILIAS. 
Should any of these require larger receptacles, remove the plants with 
care and place them in Orchid pans of proportionate size. For compost use 
a mixture of Orchid peat, osmunda fibre and moss. 
.  CATTLEYAS, L2LIAS AND THEIR HYBRIDS. 
Many of the winter-flowering kinds will now be ready for repotting. If 
so, remove them with care from the old pots, and after cutting away all 
useless back bulbs, leaving three to support the new growth, place the 
plant in a pot filled three parts full of broken crocks. Spread out the roots, 
and on no account pot low. Use for compost a mixture of osmunda fibre 
and sphagnum moss. 
CyYPRIPEDIUMS. 
For the green-leaved section, such as C. insigne, Charlesworthii, 
Leeanum, villosum, &c., I like a compost of good crushed crocks and 
fibrous yellow loam. Any plants of the above, or of their many hybrids, 
may be repotted. Carefully work out any sour soil, and if any plants have 
become crowded at the centre, carefully separate them. They can again 
be potted into one pot if it is desired to have a specimen. In this case the 
pieces should be planted near the edge of the pot, leaving room for 
extension on all sides. They may, however, be potted up singly, and will 
then quickly increase the stock. For the mottled-leaved section, such as 
C. barbatum, callosum, Curtisii, tonsum, &c., the addition of Orchid peat 
is of much benefit. 
GENERAL NOTES ON POTTING. 
Never overpot an Orchid of any kind. Keep all newly-potted plants
