330 GARDENING FOR BEGINNERS 



pared for the purpose by the same firm of manufacturers ; but only spray 

 in warm, bright weather, and when the outside conditions are favourable. 

 Scale is destroyed by carefully cleaning with a brush and sponging with 

 weak, soft, soap water. Cockroaches are most destructive to the young 

 roots and tender flowers. These may be trapped by placing jars of 

 treacle and water about the stages, or phosphorus paste " chases." Wood- 

 lice are also destructive to the young roots, and may be captured by 

 hollowing out potatoes and placing them on the stages and on the potting 

 compost. Slugs and small shell snails are imported with the moss in 

 the potting compost. Bran or brewers' grain is the most serviceable 

 trap for these pests. Place them about on the stages or pots, a small 

 pinch being put on pieces of glass or broken crocks. The pests will be 

 found feeding in the evening and early morning, and may then be caught 

 and destroyed. Slugs are a sore trial in the cool Orchid house, and will 

 require to be carefully watched, as they inflict damage when the flower- 

 scapes make their appearance.
