affected parts should be slit with a sharp knife, and a mixture of charcoal 
and sulphur rubbed on the wound. When they make new growths, the 
plants should be placed in a brighter and more airy position to induce a 
better growth. This disease is highly infectious and may be transmitted to 
a healthy plant by an unclean knife used to cut off the diseased parts of 
another. 
Thrip and Scale. Frequent syringing with a nicotine insecticide 
with soap added, will control these pests. It is good practice from May to 
October to use this insecticide fortnightly as a precaution. Use a fine nozzle 
and apply all force possible. 
Cattleya Beetles. These can be controlled and, in fact, eliminated 
by systematically spraying with RED ARROW to which soap has been 
added. 
Snails and Garden Slugs are one of the worst pests. As they do 
their work at night, many people fail to account for the damage done to 
young shoots, roots, and flower-buds. KILSLUG placed on the benches in 
the late afternoon will attract them, and they will be found dead in the 
morning. 
HOUSE CULTURE 
There are a number of varieties which grow successfully in dwell¬ 
ing-houses, and these we have indicated below. While the conditions are 
apt to be dry and more subject to drafts, they will thrive very well if one 
keeps the foregoing directions in mind and uses a fine handspray on the 
foliage on bright days. The use of a metal tray under the plants filled with 
pebbles and kept damp, will assist greatly in keeping the air moist around 
the plants.
