172 THE ORCHID REVIEW. 
burning or scorching, under which condition it becomes absolutely essential 
to give copious waterings. The one condition necessitates the other, and 
when all are duly and properly attended to they harmonize, and work 
perfectly and satisfactorily. 
The Cool Orchid house must, of course, be kept as cool as possible ; 
our climate chops and changes about in such a remarkable way, however, 
that it becomes difficult for one to lay down hard and fast rules for guidance. 
See what weather we had in May! Why, it was as cold then as it was at 
Christmas. When one says as ‘‘ cool as possible,’’ he supposes, of course, 
that the weather will resemble in some degree that of summer. Doubtless 
there were many days and nights last month when a little fire heat, even in 
the Cool house, was beneficial, because then more air could be supplied, for 
Cool Orchids abhor a stuffy admosphere. See that the night air is 
admitted freely to them during the summer. 
Auguloas have now just passed out of bloom, and are making robust 
growth. I advised the repotting of these where necessary when the new 
growths were just pushing up about two months ago. It is too late to 
disturb them now. The growth is too far advanced. Let them be placed 
in a light position in the Cool house, and given a liberal supply of water at 
the roots until growth is finished. 
Odontoglossum crispum and allied varieties should always be attended 
to in accordance to their stage of growth. Keep them well under review, 
and repot any that have got in a bad state at the roots just as the new 
growth commences to break away from the base. Give them a light 
position on the stage, and keep them pretty well supplied with water during 
the summer months. Nothing is much easier to grow and keep in good 
health than Odontoglossums when a start is made with healthy plants, 
sufficient air is given, and they are kept perfectly free from insect pests, such 
as thrips and aphis. When O. crispum becomes weekly in health it is not 
always an easy task to restore it to vigorous growth again. It may take 
years of anxious and careful treatment. Frequently debilitated plants will 
start new breaks in abundance, starting to grow from almost every bulb. 
This must be taken for nothing but an undesirable sign, and unless all 
growths, with the exception of the leading one, are removed on their 
appearance, the ruin of the plant is not far ahead. Death of the old 
pseudobulbs, and the formation of a number of tiny useless ones, is the 
result. 
Cochlioda Noetzliana is a pretty thing, as also are C. rosea, C. 
sanguinea, and C. vulcanica. They all require identical treatment to the 
coo. Odontoglostums, excepting, perhaps, that as they are rather smaller 
growing plants, they will have a better chance of receiving their full share 
of light and air, if grown in baskets or pans and suspended from the roof.
