The Garden Under Glass

PESTS AND THEIR EXTERMINATION 289 can be found ; but where they cannot be found, or are in such a place that boiling water cannot be poured on they must be trapped by setting some tempting baits for them, such as pots smeared with jam, fresh bones, etc. When found, the simplest method is to scald them with boiling water. They may often be kept from getting to the fruit by tying cotton wool around the branch or setting a grease band on the stem of peach-trees. Black-fly.—Rather troublesome with Chrysanthemums in the summer months. It gets into the points of the growths and, of course, cripples them. An easy remedy is to dust the points with tobacco powder or to syringe them forcibly with quassia extract. If taken in hånd in the first instance there should be no difficulty in keeping the pest in check. Bees.—These can hardly be called pests, because they do so much good in setting the fruit. A fruit grower loves nothing better than the hum of bees around his trees when fully in bioom. But we are not so anxious to have our flowers set seeds because their beauty so quickly departs. That is why bees become a nuisance when they visit our freesias, causing them quickly to wither, or tear open our choicest carnations. The only remedy is to screen the plants from them by means of muslin or to keep them out of the greenhouse by tacking tiffany over the ventilating spaces. Beetles.—An unqualified pest, for they eat many plants in the greenhouse. Special beetle traps may be bought and will account for a great many, but many may be killed by going into the greenhouse at night and turning a strong light quickly upon the floor or the staging, wherever they are likely to be. Phosphorus paste will also account for a great many. Cockroaches may be got rid of in the same way. T
