in watering. During the growing season the sphagnum moss on the surface 
has been kept green and in a growing condition by frequent supplies of 
water, but it should now be allowed to become quite dry before water is 
given. During the autumn and winter months it is not advisable to dip 
the plants into water, but merely to sprinkle the surface of the moss, and 
around the sides of the basket occasionally, using a sprayer or fine rose 
watering-can for the purpose. Allow no water to remain on the foliage or 
in the centre of the plants. Any failure to attend to these details may lead 
to spotting of the leaves. Such green-leaved species as P. violacea, 
Luddemanniana, tetraspis, sumatrana, speciosa, &c., are still growing, but 
at this season they must not be kept Saturated at the roots for long together. 
Sponge the plants over occasionally, especially if any gummy exudation: 
appears, as it often does at this time of the year. 
DENDROBIUMS.—Plants of such Dendrobiums as D. thyrsiflorum,,. 
densiflorum, Schrcederi, and Farmeri, that have finished up their growth, 
should now be removed from their growing quarters to a more cool and 
airy atmosphere. If any of these plants have started again into growth, 
place them in a light position in the warmest house until it is completed, 
for as the plants of this section grow very rapidly there will be time to get 
these late growths ripened. So soon as plants of D. ochreatum (Cam- 
bridgeanum) which are now dormant in the Vimery or resting-house, 
recommence to grow they may be placed in the Intermediate or Cool house, 
where they may be kept till the young breaks have grown enough to show 
prominently their flower buds, when they may be removed to a slightly 
warmer temperature. From the moment this plant commences to grow, 
afford it good growing treatment, for no amount of drying or ripening 
after this will induce it to flower. 
AERIDES, &c.—Many of the spring and early summer flowering Aérides, 
Angra:cums, and Saccolabiums will by the end of this month have passed 
their growing season ; and although these distichous and evergreen plants 
never really stop growing, they require, in a great measure, to be treated 
as resting plants, more particularly as regards affording water at the 
roots, which must be given only just often enough to prevent loss of 
foliage. All through the summer months the moss on the surface of the 
pots has been kept fresh and green, owing to the frequent waterings given, 
but now, or rather in a few weeks time, the surface moss must be allowed 
to become of a whitish green colour before water is given, and then the 
quantity must be considerably reduced. The cooler-growing Aérides, as A. 
Schreederi (figured at page 256), crispum, Lindleyanum, crassifolium ee 
Warneri have up to the present time only made up half their growth, and 
for some time should be kept moderately moist at the root. These fine 
Orchids are generally grown in too much heat, and insufficient ventilation,-
