AUGUST, 1908.] THE ORCHID REVIEW. 235 
dressed plants are staged, and not quite so much ventilation given at their 
end of the house. Spraying overhead in nice weather will help to establish 
them again. 
Odontoglossum Rossii, Uroskinneri, Cervantesii, and bictoniense do 
better in an intermediate temperature if room can be found for them. O. 
Rossii and Cervantesii grow well in pans suspended from the roof. 
CyPRIPEDIUMS.—C., insigne, Fairrieanum, and their hybrids will soon be 
showing their flower spikes. Frequently in large plants the leaves over- 
hang each other considerably, and stakes should be put in tq keep them 
from interfering with the growth of the spike, as the young spikes have not 
strength enough to push the leaves over from them. Care should be taken 
in watering, but they should never be dried off. They will require sufficient 
water to just keep them moist at all times. The size of the pot and dry- 
ness of the house must always be taken into consideration when watering, 
as well as the compost they have been potted in. When plants are received 
from different sources I find the best thing to do with them is to get them 
potted into our own compost as soon as possible, and then I know what I 
am watering, as there are hardly two growers who use the same compost or 
pot in the same way—and not only is this the case with Cypripediums but 
with all classes of Orchids. If one knows the conditions and a plant goes 
wrong—as they will at times, even with the best growers—one can generally 
get at the cause of it, and with a little care restore it to health. A short 
time since, when looking through a collection of Orchids I was asked what 
was the cause of them not doing well. The houses were all right, also the 
hot water piping and the water supply, but when I pointed out what was 
the cause of it, namely, plants in too many different growers’ composts, 
and all getting watered as for one style of potting, the answer was: ‘‘ Well, 
they were all right when they came, so how could that be the cause?” It 
was some time since some of them came, by the look of some of them, 
and had they all been potted the first season they had been there, they 
would probably have been all right now. 
CaTTLEyAs.—There will still be Cattleyas and Lzlias and hybrids to 
pot or topdress, for with the great variety of these we have now, and 
flowering, as they do, all the year round, there are always a few that want 
potting, and these should not be left till any certain season. Pot or top- 
dress them as soon as they commence to make new rocts, then they do not 
get checked when making up their new growth. A little space can always 
be found where they can have a little extra attention given them until they 
get hold again, and then they can be put in their usual quarters. Little 
things done at the right time make all the difference to the appearance 
of a collection, and it keeps everything in a healthy state. 
SHADING.—Dendrobiums should have the shading removed altogether
