342 THE ORCHID REVIEW. 
without such houses success could not beattained. Many of them, however, 
could be grown well by amateurs who had only one ordinary greenhouse 
and acold frame. The lecturer commenced growing Orchids in a rather 
close and stuffy fernery facing north, but soon found that such conditions 
were adverse to their well-being. He then excavated to a depth of about 
eighteen inches under a north wall, and concreted the bottom, which he 
covered with water. Over this he placed a frame, standing the plants on 
inverted pots over the water. Many of the cool equatorial Orchids came 
from close damp woods where there was but little winter or summer, as we 
know these seasons, and to imitate these conditions as far as possible the 
lights were taken off entirely during wet or dewy days and nights, but 
during dry days they were closed. ‘The plants were put into this frame in 
the late days of spring, and removed again at the end of September, when 
it was found that they had recovered themselves greatly and made abundance 
of roots. They were then placed in an eastern aspect in the greenhouse, 
and each stood over a saucer of water, where they fared well until March, 
when canvas screens were required to protect them from the sun, then 
beginning to obtain power. Afterwards, when again put into the frame, the 
plants grew away at once, and in September were remarkable specimens, 
most of them having healthy flower-spikes in their strong new growths. 
The system proved remarkably successful, with the exception of the hot, 
dry season of 1893, when the absence of rain during the hottest period of 
the year made it extremely difficult to keep the plants cool and moist. The 
idea was to keep them as cool and moist as possible during our summer, 
when they were better able to stand the winter, neither extremes occurring 
in their native homes, where they were always cool and moist. Some of the 
species he found amenable to this treatment were Odontoglossums crispum, 
Pescatorei triumphans, Rossii, also O. x hebraicum and others, while those 
which enjoyed the summer treatment, but required a slightly warmer place 
than the cold greenhouse during winter were Odontoglossum grande and 
Epidendrum vitellinum. Certain modifications in the treatment had been 
found necessary for other species, though for the most part such special 
treatment was only required during part of the season. For these details 
our readers are referred to the Society’s Fournal, where the paper will 
doubtless appear in full. We welcome any means of popularising the 
cultivation of these charming plants.
