THE SINGLE ORCHID HOUSE 1g 
Further remarks on this and other details will be found 
under the headings of the different genera, but it will be 
better now to state in general terms that during the season 
of active growth any reasonably high temperature by sun- 
heat, secured by keeping the house tolerably close and 
well shaded, greatly benefits the plants. This is specially 
noticeable where batches of Dendrobium nobile, D, War- 
dianum, and other deciduous Dendrobiums are grown. 
Those who grow them best allow the house containing the 
plants to become very warm; they remove the shading 
early in the afternoon in order to let the plants get the 
longest duration of light possible, and they keep the house 
very moist until the evening. 
THE SINGLE ORCHID HOUSE 
It is doubtful whether the owner of a large collection 
of Orchids gets a greater amount of pleasure than the be- 
ginner starting with but one Orchid house, provided the 
owner of the single structure is careful in selecting his plants. 
In cases where only one Orchid house is possible, and 
a more or less general collection of plants is desired, that 
house should be heated as an intermediate house. The 
single Orchid house has often been the starting-point of 
more extensive culture. It is generally commenced by 
utilising an existing plant-house, in some cases, unfortu- 
nately, without making the necessary preparation for the 
new occupants. 
When it has been decided to adapt a house for Orchids, 
the proper course is to clear the house of its contents, 
thoroughly overhaul the interior fittings, such as staging, &c.,
