SPOT. The appearance of small, dark brown spots on 
the leaves and pseudo-bulbs is usually an indication of cold and 
overwatering. The affected parts should be slit with a sharp 
knife, and a mixture of charcoal and sulphur rubbed on the wound. 
THRIP and SCALE. Frequent syringing with a nicotine 
insecticide, with soap added, will control these pests. It is good 
practice 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 Rotenone and 
Derris Root Insecticide 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 dwelling houses, and those recommended are Cattleya and its 
multigeneric hybrids, and Cypripediums. While the conditions 
are apt to be dry and more or less subject to drafts, they will thrive 
very well if one keeps the foregoing directions in mind—particu- 
larly relative to night temperature and humidity—and uses a fine 
hand spray on the foliage on bright days. The use of a metal tray 
under the plants filled with pebbles and kept damp will greatly 
assist in keeping the air moist around the plants. 
CONCLUSION 
The amateur can grow healthy plants and enjoy beautiful 
flowers in his leisure time if general directions are followed. Many 
of the chances for failure can be eliminated by precautions taken 
upon acquiring plants. Buy only established plants of strong, healthy 
growth and free from disease and insects at the outset. Keep your 
plants clean, learn the simple rules for temperature, ventilation, 
watering, shade and light, and your efforts are sure to be crowned 
with success.
