76 THE ORCHID REVIEW. [Marcu, 1903. 
growth is in full progress do not stint them for water, as anything 
approaching dryness at the root during this stage of growth will be 
detrimental to their well-doing. C. cristata delights in plenty of light, but 
not actual sunshine. A position at the coolest end of the Cattleya House 
will suit it the whole year round. 
Thunias will now require re-potting. They may be potted singly, or 
placed six or seven bulbs about three inches apart in a ten-inch pot, which 
should be half filled with drainage, using loam, peat, and moss in equal 
proportions. Choose a position in the warmest house and as close to the 
glass as possible. The successful blooming of these plants depends largely 
upon the amount of light they get. See that each bulb is secured firmly to 
a stick, and when the growths are well advanced and rooting freely, give 
abundance of water, and when the growths are half made up, as soon as the 
flower buds can be felt in the newly-forming stems, an occasional watering 
with liquid cow manure. Thunias can easily be propagated by taking off 
the! back bulbs, cutting them at the joints into pieces about six inches 
long, and inserting them as cuttings into a mixture of sphagnum and 
coarse silver sand. 
Calanthes of the vestita group will soon be on the move again, and 
may be repotted before the appearance of new roots. A good compost is 
necessary, and may consist of one-half good fibrous loam, one-fourth leaf 
soil, and the remainder finely chopped moss, with a good sprinkling of 
coarse silver sand or finely broken crocks; the whole being well mixed 
together. The compost being prepared, should be laid a few days prior to 
use in a suitable place to get warm. Previous to repotting, shake out all 
the old soil, and shorten back the dead roots to about an inch. This 
portion will help to keep the plants steady until new roots obtain a firm 
hold of the compost. Clean pots should be used, the sizes varying 
according to the discretion of the cultivator. I practice potting them 
singly, using five or six inch pots for the strongest bulbs, and pro- 
portionately smaller ones for the others. Give good drainage, the pots 
being rather more than half filled with clean crocks, and place upon this 
a layer of the most fibrous part of the compost, in order to prevent the 
drainage becoming choked. In filling the pots the soil should be shaken 
down moderately firm, to within an inch of the top; then place the plant 
on the surface, with additional soil added, so that the base of the bulbs is 
just covered. This will leave about half an inch of space, which will allow 
of a little top dressing of good fibrous loam when the plants become 
established. After potting place them in their growing quarters, which 
should be a light position near the glass in the warmest house. Give 0 
water at the roots fora few weeks, merely damping the stage, and syringing 
between the pots. As the young growths advance a slight sprinkling may
