crocks, thoroughly mixing the whole well together. Those plants that 
require a shift should be attended to at once, taking care to make them 
secure by the use of sticks, or tying the pseudobulbs to the suspending wires. 
where necessary. 
All newly imported plants of Dendrobium should at first be placed in 
crocks only, and kept in a cool dry house, until the young growths appear.. 
Roots will at once follow, when the plants may be potted, as above advised, 
and placed in their growing quarters. Guard against overpotting, for if the 
roots get into a mass of sodden compost, they speedily decay, and this. 
causes the young shoots to stop prematurely, and make weak, sickly 
growths. After repotting, keep the plants on the dry side for a few weeks, 
until the new roots have a firm hold of the compost, after which water may 
be more gradually and more frequently given. When thoroughly established,. 
syringing the plants will be found beneficial in keeping them free from red 
spider; also sponge the foliage occasionally with weak lemon oil and soft 
water. Dendrobiums, with but few exceptions, require a hot moist 
atmosphere, and abundance oflight when growing. Where a house cannot 
be devoted to them, an ordinary plant stove will suit them admirably. 
Propagation of the various varieties is easily effected, by taking off any of 
the back pseudobulbs which have not bloomed, cutting them into lengths,,. 
and laying them on chopped sphagnum and coarse sand, in some hot, moist, 
propagating case ; or the young growths of choice varieties, which some- 
times appear on the old bulbs, may be taken off and potted. 
Cattleya Warscewiczili (gigas), and its variety Sanderiana, are now 
pushing forward their new growths, and water should be given sparingly, or 
few flowers will follow. As soon as the sheaths are visible, new roots will 
soon appear, and then is the time to give fresh material, or repot if 
necessary. When done carefully no harm will befall the flowers or the- 
plant. As soon as the roots find their way into the compost, water may be- 
given more frequently, and in greater quantity, but an over generous supply" 
given in dull cold weather will often endanger the health of the young 
succulent bulbs. 
C. Dowiana aurea, and the forms of C x Hardyana, should have a warm: 
light position given them, and be treated similarly to the above. This- 
section often causes trouble to the grower, being so difficult to keep from 
making a second growth during the winter, after the first one has flowered, 
and this, coming so late in the year, is more often than not a failure, in 
which case the subsequent growth has to come from the secondary bud, or 
perhaps a back bulb, and in this case the growth is certain to be weak in 
comparison with that produced from the lead at the right season. 
The beautiful C. Trianz will ere this have done blooming, and a number 
of roots will be pushing from the base of the last-made pseudobulb. The:
