May-June, 1919.] THE ORCHID REVIEW. Sr 
and if carried too far will cause them to die from shrivelling, and the effect 
to the plant is much the same in both cases. 
SHADING will now be general, and requires considerable attention, as the 
blinds should only be down when really necessary. The sun should not be 
allowed to shine directly on the plants when there is a danger of the plants 
suffering. Orchids comprise both sun-loving and shade-loving kinds, hence . 
the necessity of a close obsetvation of the effect of strong light on the 
different classes, and a corresponding arrangement of the plants in accord- 
ance with their natural requirements. Nature is inexorable in this respect, 
and whatever pains or trouble we bestow on ascertaining the requirements 
of the respective plants under our care, the better and greater will be our 
reward. 
SUMMER QUARTERS.—Those plants which thrive under an equable 
temperature the whole year round should be removed from the Intermediate 
house, where they have passed the winter, to the Cool house, where they 
may remain until the autumn. These include Lelia harpophylla, pumila, 
prestans, Jongheana, and Dayana, Dendrobium infundibulum and James- 
ianum, Odontoglossum Krameri and nzvium, Miltonia vexillaria and its 
hybrids, as they go out of bloom, also M. Phalaenopsis, Endresii, and 
Schreederiana, with Ada aurantiaca, which all do better during the winter 
in a light position in the Intermediate house. During the summer they 
prefer the Cool house. In different districts, the most suitable time to 
femove them will vary, but it may safely be done when the Cool house rises 
to 60° without the aid of fire heat. For some little time after removal it is 
advisable to keep the plants a trifle drier at the root than they have been in 
the warmer division. Some of the Masdevallias thrive remarkably under 
these conditions, especially those of the Chimera section, M. tovarensis, 
and a few others. : 
_ ANGULOAs.—In the Cool house the various Anguloas are making new 
growth, and pushing up their flower spikes. When their flowering period 
has passed they may have attention as regards repotting, should they 
tequire it. They will succeed planted ina well-drained compost of clean 
fibre, in which a small pottion of good loam fibre may be added. When 
Tepotting, keep the base of the young growths on a level with the rim of the 
Pot, and place the material quite firmly around each plant. ‘ 
to pot loosely, with the present day materials. Water carefully until the 
New roots get freely established in the new material. 
LycastEs that require new rooting material when thei 
has passed may be treated in precisely the same manner as Anguloas. : 
CatrLeyas.—Amongst those which are in flower at ihe presses Gil arr. 
C. Mendelii, C, Mossi, and their innumerable hybrids. C. Triane and 
C, Schroederz, with their hybrids, are commencing to make new roots, and
