should be kept at a reasonable distance from the glass, and be placed out of

Resting Period. —The treatment of Orchids during this period involves 
even more care and thought than are required during the season of growth, 
and there are few matters in their cultivation that are more often misunder¬ 
stood by; the .novice. Rest is not, perhaps, the exact term to use, for what 
is required is a gradual and natural cessation of growth, so far as aft 
outward appearance goes, for a longer or shorter period, according to the 
habit of,the plant. If all Orchids were alike in their needs, it would make 
, the resting season a much less anxious time for the cultivator, but they are 
not; therefore the grower has always to be on the alert, and give to each 
plant the attention it needs during this state of comparative inactivity. 
When a number of Orchids varying much in their time and manner of 
resting are grown together in one house, it is impossible to arrive at a 
common method of treatment that will suit all alike. It becomes, however, 
necessary to adopt what one may term a compromise as regards temperature 
and atmospheric conditions, to which the plants are perforce obliged to be 
made to submit in the compartment at command for their cultivation. 
Independently of the necessity in the case of many Orchids for a proper 
resting period to ensure their satisfactory flowering, such rest is equally 
requsite to> rhaintain their proper period of growth, hence the obligation to 
provide a cooler, drier atmosphere, and to afford water to the roots only in 
sufficent quantities to keep leaves, pseudo-bulbs, and roots in a healthy 
condition. All Orchids that require to be kept dry at the roots during their 
season of rest will be able to benefit by this to an extent depending upon the 
conditions under which they have been grown during the last and 
preceding seasons. If the leaves and the pseudo-bulbs are well developed 
and properly matured, especially the evergreen species, they are always 
better able to bear a lengthend period of drought without shrivelling to an 
extent that will injure the foliage. Plants of the Cattleya family are 
sometimes weakened when the rooting materials are allowed to dry 
excessively. Enough water should in all cases be supplied to the roots, 
although more than will prevent shrivelling of the pseudo-bulbs and foliage 
is injurious at this season. The same remarks aj>ply to Dendrobiums, 
Oncidiums, and similar genera. Catasetums, Chysis, Cynoches and many 
other deciduous Orchids, if their bulbs are thoroughly ripened, seldom 
require water after the foliage has fallen, but should any plants appear to be 
shrivelling unduly, a good watering should be given, and no more, because if 
kept moist at the roots the flowers are never so freely produced. The ever¬ 
green distichous-leaved Orchids, such as Vanda, Saccolabium, Aerides and 
Phaiaenopsis require more .moisture during the winter than the pseudo- 
bulbous kinds. Very little water is, however, needed by these during the
