304 THE: ORCHID REVIEW. [DECEMBER, 1923. 
producing two spikes, each with no less than forty flowers, and creating a 
fine example of successful culture. One of the gems of this collection is 
‘Oncidium splendidum holoxanthum, with flowers entirely yellow and so 
rich in this colour that when sent to Mr. F. Bolas for the purpose of having 
a painting executed he replied that he would do his best, but was afraid 
there was no colour that would do the flowers justice. 
Electric light, produced by a private plant, is everywhere installed, and 
even the boiler has an electric fan fitted to the chimney so that the draught 
can be accelerated when necessary. Although only a few of the many 
Orchids in this collection have been mentioned, full praise is due to 
Mr. W. A. Stewart for the able manner in which he cultivates them, they 
are clean, very healthy and yield an abundance of bloom in their respective 
seasons. 
CULTURAL NOTES. 
By J. CoLiigRr, Gardener to Sir Jeremiah Colman, Bart., Gatton Park, Reigate. 
E have now reached one of the most sunless months of the year, and 
great care should be excercised in regulating the temperatures and 
atmospheric conditions of the Orchid houses; endeavour to keep the 
temperature as even as possible. During frosty weather, when fire-heat is 
necessary, the atmosphere should be prevented from becoming too dry. 
On bright mornings following frosty nights, as soon as the temperature 
commences to rise to the proper degree, every available space should be 
moistened by syringing bare spaces between the pots, the paths and 
underneath the hot-water pipes. The East Indian and Cattleya houses 
should be damped between 2 and 3 p.m. One damping should suffice for 
the Odontoglossum house, but at all times the amount of atmospheric 
moisture should be regulated according to the weather. 
TEMPERATURES,— The winter night temperatures should read somewhat 
as follows. East Indian house, 63° to 68°; Cattleya house, 58° to 63° ; 
Cool or Odontoglossum house, 50° to 54°. On very cold nights the lower 
temperatures will be sufficient, as an excess of fire-heat may prove harmful 
to the plants. During very cold weather the temperatures should be about 
five degrees warmer at mid-day than in the early morning, but the 
thermometer may be allowed to rise several degrees higher during periods 
of bright sunshine. If lath blinds are fixed to the houses, they may be 
lowered during very cold nights; if permanent blinds are not used, the 
glass may be protected by some other covering, such as archangel mats. 
Their use will prevent the temperature from fluctuating, economise fuel, and 
keep the atmosphere from becoming very dry. 
VENTILATION.—Admit fresh air whenever it is possible to do so without
