round. It is not much use trying to rest them in winter, as it encourages 
thrip, and if thrip once gets hold they might just as well be thrown away 
as they seldom recover. 
CYPRIPEDIUMS will nearly all have finished flowering, and should be 
examined, and potted or top-dressed if they require it. Get them growing 
as soon as possible, soas to give them a good chance to make their growths 
for flowering next season. Keep them well syringed, asit keepsthem clean, 
and also keeps a good growing atmosphere in the house. Care should be 
taken in ventilating, as Cypripediums object very much to cold draughts 
blowing on them. 
The C. bellatulum, Godefroyz, and niveum hybrids do not object to 
syringing in summer time, but it should not be done quite so heavily as with 
the other species. This class will be better staged by themselves, as a little 
more care is required for them, and then they can all be examined without 
having to hunt through the house for them. When potting, give them a 
little extra drainage, and also mix more crushed crocks in the material. 
They like plenty of water in the growing season, but must on no account be 
allowed to get sodden. They do not require as heavy a shade as other 
Cypripediums, in fact we treat ours more as Cattleyas in this respect, and 
get fine results. Bottom air can be left on just at their end of the house day 
and night during the summer, as they like to get dry at night, and it 
prevents the leaves from damping off. The flowers also come much finer, 
and the plants get harder and go through the winter much better. 
CaATTLEYAS, Dendrobiums, and Lelias that have been recently potted, 
and have commenced rooting, should have a good supply of water as soon as 
the roots get over the tops of the pots, also more sunlight, care being taken 
not to scorch the leaves. They will stand a lot more sun than most Orchids, 
and benefit by it. If they are syringed overhead ona nice afternoon, and 
the blinds are rolled up between 3 and 4 o'clock, and the air taken off 
for three hours or so, they will make fine strong bulbs, and it seems to 
freshen them up to close the house up for a short time with plenty of 
moisture and sunheat. The power of the sun must be considered when 
rolling up the blinds, also the position of the house, as some days, although 
the sun is bright, it has no power to scorch plants, whilst on other days it 
will easily burn though not nearly so bright. I find this the only way in the 
north to get growths anything approaching the southern growers, who get 
much more sun than we do, and also clearer days. 
At a recent exhibition of the Manchester Orchid Society there was a 
magnificent group of Dendrobiums shown from the South, which should 
help to make them more popular round Manchester, as I think with a little 
attention they could be well grown ifadvantage is taken of what sun we do 
get. The plants and flowers of D. nobile album, of which 200 plants were
