300 THE ORCHID REVIEW. [OcToBER, 1903+ 
should be washed some time during the month. After the outside has been — 
done a commencement should be made inside, and every part should have — 
a thorough cleaning, washing the woodwork, glass, and everything that will — 
add to the cleanliness of the houses and the appearance of the plants. | 
When a house has been cleared, the occupants should be arranged so — 
that each one has its due share of light, according to its known require- 
ments, favouring those, if any favour be shown, that are still in an active 
state, so that the growths may develop and mature before the winter. If 
there are any plants that are behind in this respect, it is best to remove 
them to where a slightly higher temperature is kept up, rather than increase 
that of the house they occupy. I am now speaking more particularly of 
Cattleyas, Lzlias, Dendrobiums, &c., and not Cool house subjects, which 
in many cases are slowly making growth all through the winter. Deciduous 
plants, such as Catasetums, Mormodes, Calanthes, &c., although they have 
no leaves, will still need light to mature their pseudo-bulbs, and in the case — 
of the latter, aid the development of flower-spikes. Those in pots may find — 
a suitable place on a shelf near the glass, taking them down occasionally, ; 
and watering those that are in need of it, by immersing the pots to their — 
tims in a pail of water. The deciduous Dendrobiums will also need all the 
light obtainable, as much now that they have lost their leaves as they did 4 
before, but Thunias, when the leaves have fallen away, and the stem-like ~ 
bulbs have become ripened, need not be placed in a light position, if room is q 
Scarce, but may be laid under a stage in such a way that the stems do not 3 
lie flat on the earth, and in a position where drip cannot fall on them. 4 
Two watm-growing Oncidiums, Kramerianum and Papilio, are highly — 
appreciated when in bloom, their butterfly-like flowers being very — 
attractive and interesting. These have been in flower for some time, and ~ 
will continue to produce fresh flowers from each stem for a considerable 
period longer. These beautiful Oncidiums prefer a light position, and 
should be suspended close to the roof glass, in either pan or basket, with 
but a small quantity of material to root into, which should be kept ina fairly 4 
moist condition. 
Amongst easily grown Orchids are the Sobralias, yet they do not receive 
as much favour with cultivators as they deserve. Large specimens may 
now have the old reeds that have flowered 
more room tO grow, and at the same time allow more air and light to reach 
them. It is still seasonable to repot any of them that require such attet- 
tion, but as their treatment has been given in a former Calendar, it will be 
only necessary to add that they must be kept clean and free from thrips, 
and watered Sparingly for the next few months. 
. Anguloas, when they have finished up their bulbs, will only need 
ucient water to prevent the latter from shrivelling, the same rem 
cut out, to give the young ones
