luwns, and when least expected. But few 

 Orchid flowers can stand foggy weather, so 

 that when it arrives every means must l)e 

 used to keep the injurious atmosphere out of 

 the house by shutting all ventilators and 

 opening the doors as seldom as possible. 

 Even with these precautions the fog, if 

 continuous, will sooner or later find an 

 entrance, but every hour of preventing its 

 access to the plants is so many points towards 

 tlieir good health. 



Cleaning the plants is an occupation that 

 may often be done in odd hours, and even 

 during the evening by means of artificial 

 light. No matter how clean the house itself 

 may be, it is generally possible to find some 

 scale on plants of the Cattleya kind ; its 

 presence is easily detected on the under side 

 of the leaves, but search should specially be 

 made under the white skin which has a dried 

 and dead-like look and surrounds the matured 

 bulbs. If no scale is to be seen it is better 

 for the sake of appearance not to disturb this 

 outer skin, although its removal does not 

 seem to affect the condition of the plant, that 

 is, of course, providing the bulbs are fully 

 matured. This scale clings tenaciously and 

 its removal is best effected by means of 

 suitable insecticide ; if after a few minutes' 

 application it still adheres a pointed stick or 

 blunt knife will be required. Another 

 favourite place for scale is on the rhizome 

 and dormant eyes at the base of the bulb, 

 and much care is needed to remove it 

 without damaging the sensitive part of the 

 plant. 



Dendrobiums are also liable to be attacked, 

 and require careful attention, although when 

 certain leaves are badly affected and disfigured 

 it will be found best to totally remove them. 

 Scale is very rarely found on Odontoglossums, 

 the.se cool-house plants being favourite 

 subjects for thrips, which delight to damage 

 the flower spikes and disfigure the new 

 growth. Fumigation is generally effectual, 

 care being taken that water is not lodging in 

 the growths, or it may prove a source of 

 retreat for the thrips until the fumes have 

 passed away, when they will march forth 

 once again on their work of destruction.
