and only the loose, sour, and decomposed compost should be picked out 
with as little disturbance as possible. Well-drained pots, pans, or baskets 
are suitable receptacles for these plants, and the potting compost should 
consist of equal portions of peat, polypodium and osmunda fibres, and 
sphagnum moss. Pot the plants moderately firmly, keeping the base of 
each plant slightly below the rim of the receptacles. During the early 
stages of growth only sufficient water should be given to keep the plant 
plump and the rooting material moist, but when the roots enter the new 
material more liberal supplies may be given. From the time that the 
plants are established until their pseudobulbs are fully developed a hot, 
moist buoyant atmosphere is necessary. The plants delight in a clear light, 
but at the present time, owing to their being repotted, shading is necessary. 
Young seedling Dendrobiums may also be repotted at this season. The 
usual methods of propagation, by cutting the bulbs into lengths and sticking 
them into pots of clean sand, or laying them upon growing sphagnum moss 
may be practiced. 
MiLtTonias.—Plants of Miltonia vexillaria and its hybrids that are 
pushing up their flower spikes must not be allowed to suffer for the want of 
water at the roots, but a moderately dry atmosphere must be maintained, 
or there is a danger of the flowers becoming spotted. When the flowers 
are opened under cool conditions, as advised last month, they are of a much 
better colour, and last longer in bloom. 
CaTTLeyas, Laxias, and L&@LIOCATTLEYAS.—Any necessary repotting 
must be attended to when these plants have passed out of bloom and are 
making new roots. There will be quite a number of the hybrids as well as 
some of the species, which will arrive at the proper stage during the present 
month, and it is wise to carefully note the plants so that they may be done 
before the roots attain any great length, when there is less danger of their 
getting broken or injured. If this routine is carried on systematically each 
One will get attention in its proper season, and many Cattleyas resent 
disturbance at the roots at any other time. Cattleya gigas, C. aurea, and 
their hybrids are now starting vigorously into growth, and must be carefully 
watered until the growths get nicely away, when they may have more 
liberal supplies. They should all be placed in the warmest position in the 
Cattleya house. Lelia anceps that are in need of repotting should be 
completed at once, as they.delight in a long season of growth, and if left 
too late they often fail to re-establish themselves. 
Lycastes.—Plants of this genus, species or hybrids, will develop new 
growths as they pass out of flower, and any that are in need of new rooting 
material should be repotted. Specimens that are potbound should be given 
larger pots, sufficiently large to acommodate them for at least two seasons. 
Plants that have lost their roots, from a too liberal supply of water or from
