It was one kind of gall fly that made the little "brown house" that the children found among their nuts when they came home; but this kind is not the ink-making fly. Shellac. There are several kinds of gall flies that pierce a hole in the leaf of the black oak, and in this they lay an egg. Their sharp sting causes the leaf to swell, and all the sap in the leaf flows toward that part; so when the larval baby is hatched out it has plenty of rich sap to feed upon. After a time it makes a cocoon for itself, and becomes a pupa, or real baby fly. When its baby days are ended it creeps out of its soft blanket, makes a round door in its small brown house, and comes out with wings! Its little house is called a gall nut, and they are often found in the stems, leaves, and buds of plants; such flies do much harm. All will agree that insects are of use in carrying pollen from one flower to another; for in this way they help to ripen the seeds, as flowers cannot form seeds without pollen. In some flowers where there is no pollen the plant would die out did not the busy insect bring it on its body and wings. But there are flowers where there may be plenty of pollen, and yet their seeds are not of much worth unless they can borrow pollen from their neighbors. And so, very often, it happens that two flowers of the same kind will exchange pollen; and then some honey-seeking insect acts as the little "go-between" in doing their errands. But after we have said the very best that we can, about insects and their uses, we are still quite sure that the greater number of them are really more harmful than helpful in the world. THE HIDDEN SONGSTER. Hark! Hear you no...
