2367. Grubs on Orchard Trees.—Make a bonfire with dry sticks and weeds on the windward side of the orchard, so that the smoke may blow among the trees; you will destroy thousands; for the grubs have such an objection to smoke, that very little of it makes them roll themselves up and fall off; they must be swept up afterward.
2368. Wasps destroy a good deal of fruit, but every pair of wasps killed in spring saves the trouble and annoyance of a swarm in autumn.
2369. Butterflies and Moths, however pretty, are the worst enemies one can have in a garden; a single insect of this kind may deposit eggs enough to overrun a tree with caterpillars, therefore they should be destroyed at any cost of trouble.
2370. The only moth that you must spare, is the common black and red one; the grubs of this feed exclusively on grounsel, and are therefore a valuable ally of the gardener.
2371. Earwigs are very destructive insects; their favorite food is the petals of roses, pinks, dahlias, and other flowers.
