248 THE ORCHID REVIEW. 
But to proceed. Dendrobium Wardianum having finished its growth 
should be taken to cooler quarters, and given a long season of rest, as it is 
thus kept longer in good health. Give the plants the full benefit of sun and 
air, but be cautious not to discontinue the water at the roots at the same 
time—nor indeed to any other Orchid—for if this is done shrivelling rapidly 
follows and a great check is the result. Apply water as usual, and as the 
new pseudobulbs become more and more hard and matured, the supply 
of water should be gradually diminished, until by the time the dull weather 
sets in they are able to endure drought for weeks. Some may have an idea 
that to withhold water at this early stage will prevent the appearance of a 
second growth, but such a check is more likely to cause immature growth 
than otherwise. Where it is advisable to prevent second growth the same 
year, sole reliance must be placed upon free ventilation and cooler treatment 
generally after the first growth is completed. Under the most careful and 
skilful treatment a small percentage of plants are almost sure to start 
growing again, but on no account should such plants be again placed in a 
growing temperature with a view to accelerate the completion of a second 
pseudobulb, as such treatment is unnatural and weakening. The proper 
way is to go on with the gradual ripening process, and simply ignore the 
existence of new growth. 
The above remarks on watering and resting Orchids apply to most 
of the Dendrobiums, Cattleyas, Lelias, and others that have a resting 
season, but there are exceptions. For instance there are a few Dendrobiums 
in which it is not nearly so important to stop the second growth, unless it 
is getting late in the season. I refer to D. X Ainsworthii, D. x Leechianum, 
and similar crosses, which frequently break again from the base of the 
new growths, long before the latter have finished. Supposing these second 
growths appear about mid-summer, they have sufficient time before to 
make up good pseudobulbs, and should be kept growing on for that purpose. 
But should these growths not appear before say August, it is best then not 
to encourage them, but gradually harden off the plants in cooler quarters. 
Among the Dendrobiums that are bringing their season’s growth to @ 
close will be the D. thyrsiflorum section, D. nobile, and the many hybrids of 
which it is a parent, D. chrysotoxum, &c., and these should be removed. 
Conditions similar to those which Mexican Orchids enjoy would suit them 
admirably. Autumn-flowering Dendrobiums should not be removed from 
the warm house, nor rested in any way until they have bloomed, and even 
then, in most cases, they should remain in the same house to rest. The list 
of warm-resting sorts may also be supplemented by some others which 
flower tn spring, as D. Parishii, D. Bensonie, D. aggregatum, D. 
Maccarthiz, D, albo-sanguineum, and D. superbum. All of these are 
rather capricious under cultivation, but their eccentricities may generally 
be mastered in due time if their requirements are studied and goot
