108 THE ORCHID REVIEW. [APRIL, 1908, 
very useful, as it saves time—and there is not much time to spare just now 
—and washes pots cleaner than when done by hand. It also makes the 
boy think he is a bit of an engineer as well as a pot washer, and a boy can 
wash several hundred, according to size, in half a day. 
DENDROBIUMS, as they pass out of flower, will need going through for 
potting and top-dressing. It is best to do a few at a time, as they pass out 
of bloom, and then one can easily keep pace with them, and they do not 
get left till ‘next year,” which is often the case when they are left to be 
done in bulk, especially in a place where an Orchid staff is not kept, and 
other work comes along which also has to be done.. The Cattleya mixture 
suits them well. Pot firmly and do not overpot them, as they like plenty 
of water in the growing season. A nice sunny position should be set aside 
for them, and if possiblea house to themselves, otherwise the Cattleya house 
or some such position will suit them. They are not particular so long as 
they get plenty of sun, so that they can ripen as they grow, which is much 
better for them than the winter drought so much practised. Like Lelia 
anceps, Dendrobes do not seem to be such favourites as they were a few 
years ago, still for quantity of flowers and grouping there is nothing to beat 
them for spring flowering yet, as they last in flower such a long time 
without injury to the plants, and are very little trouble to grow. Red 
spider is about the only thing that seems to bother them, and if they are 
fumigated occasionally that need not happen, especially just after they 
commence to grow, when they have been grouped for effect for some time, 
and have not perhaps received the best of attention. 
ODONTOGLOssUMsS will be coming into flower rapidly. As the days get 
brighter the house should be kept a little drier while the flowers are 
opening, unless one has a spare house where they can be staged until the | 
flowering season is over. The spikes should not be left on long enough to 
shrivel the bulbs. Odontoglossum grande will be growing strongly, and 
should have a nice sunny position, and plenty of water during the growing 
season. This variety does better in an intermediate temperature than with 
O. crispum, and they are not so liable to spot when grown in a warmer 
house.. 
SEEDLINGS will need plenty of moisture now that the sun is getting 
stronger, and must be well shaded. A movable shade is best, so as to give 
as much light as possible in the evening and dull days. As soon as the 
pots are filled with roots they should be shifted into slightly larger pots, $° 
as to keep them growing until they get to the flowering stage, when they 
can-be treated as the other flowered plants. 
CaLANTHES should be potted as soon as they commence to grow: 
When stored in boxes on a shelf after flowering they can be left till the 
growth sends out roots, and if carefully handled when potted, they soo”
