requirements of each individual species, which will also serve as a guide 
to the treatment of their hybrids. 
It has likewise been a grand season for all inmates of the Mexican 
house. Mexican Leelias and allies are in many gardens grown exceedingly 
well in the ordinary Cattleya and Intermediate departments, so that it is 
not absolutely necessary to have a sunny house set apart for them. But, 
as I have before explained, it is not at all a bad plan if such a house can 
be set apart for them, for not only do they get a better chance to do really 
well, but such a house is exceptionally convenient at this season for 
ripening off the various species which require thorough good ripening, 
besides providing a suitable place where one can experiment with difficult 
growing species, and there are usually a few such in every genus. 
East InpIAN Hovuse.—The temperature here should also be lowered by 
a few degrees, and damping down twice daily should now be sufficient. 
Use no more warmth from the hot-water pipes than is necessary to 
maintain the requisite degree of heat, for to have more than is really 
necessary is most injurious to the plants, and quickly reduces their health 
and vigour. Saccolabiums, Angraecums, Phalznopses, Aérides, and Vandas 
will now have partially finished their season’s growth, which of course re- 
quires to be matured to a certain extent, and therefore the supply of water at 
the roots must be slightly reduced, so that they may prepare for the coming 
winter. They should also be less heavily shaded, but it must be reduced 
very cautiously, for it must be remembered that Orchids of this class, 
having no pseudobulbs, have to rely on their handsome leaves, not only for 
their appearance, but their strength also, and therefore the leaves should be 
preserved intact as long as possible. A sudden and protracted exposure to 
strong sunshine, or an excessive drought, before these new leaves are some- 
what matured, may therefore do an immense amount of damage. 
RE-POTTING.—-There may still be a few plants distributed about a 
collection that may be in a suitable condition for re-potting, and these 
should be attended to. It is, of course, too late to re-pot on a large scale, 
and any that are now done should be handled with the greatest care, and 
be given afterwards suitable treatment to encourage the roots to grow 
freely. Those which may yet be done include Cattleya Eldorado, C. 
superba, and a few other late kinds that, for various reasons, have not been 
ready for re-potting before. Some of these are just pushing out new roots 
from the base, and may be taken in hand, using special care not to break 
the roots, and afterwards giving special treatment by keeping their 
surroundings better supplied with moisture than is necessary for most 
others at this date, so that their recovery may be accelerated. The two 
beautiful species just mentioned are particularly partial to warmth and 
moisture when growing, and do not at any time relish a too rigorous
