TREATMENT OF ORCHIDS FOR EXHIBITION.—Those of us who exhibit 
Orchids more or less all the year round know too well the evil effects on 
the plants, but with some preparation beforehand, and careful treatment 
after their return to the houses, much can be done towards reducing the 
mischief. It often happens that the plants being shown are out of the 
houses for five or six days, and in some cases during most of that time they 
have only the protection that a canvas structure affords. There must of 
necessity be entrances, and plants that in a general way at home are 
treated so that no direct air is allowed to play upon them have to put up 
with cold draughts and any weather that may come along, so that unless 
the plants have been in some degree hardened and prepared, disaster will 
frequently follow. 
All plants that are grown in warm structures should be removed a few 
days before hand to cooler and more airy houses, and they should be kept 
well on the dry side before being packed, and allowed to remain so during 
the time they are at the exhibition. My experience has taught me that 
plants that have been well dry from the time they were removed from the 
houses till their return are the ones that suffer least, but it is not so 
important with such plants as Cymbidiums, Odontoglossums, and other 
cool-grown varieties, as it is with Cattleyas, Lelias, Phalaenopsis, etc., but 
in all cases the least harm accrues when they are on the dry side. 
When the plants get home all flowers should be removed, and for a few 
days no water should be given them. The harmful effects of exhibiting are 
not often apparent at first, and J think the foliage never suffers to the same 
extent as the roots. One may think when the Show is over that the plants 
are none the worse, but when the new growth starts away a great differ- 
ence can often be seen, and this is generally caused by the plant being in 4 
somewhat wet state, and the roots getting chilled during the time the 
plants were out of the houses. A plant may shrivel by being kept so dry; 
but that is a much less evil than losing the roots, and I am sure that when 
well dry the roots will come safely through such a time, when if they had 
been in a wet state they would ultimately have rotted. Withall precaution 
harm must accrue, and the only thing one can do is to lessen the amount, 
and always be prepared for any emergency.

be over, and plants that are not flowering this year will be forward enough 
in growth to enable potting to be done. By reason of the very long sease?
