MARBLES ON TREES
--- Do you know what makes marbles and apples grow on oak trees, and. pin eushions on wild rose bushes? Karly in the spring, a gossamer-winged insect, caljed a.gall-wasp, alights on an oak twig, and piercing a hole in the bud with her long probe, places an egg inside it. Then a wonderful thing happens Instead of the bud withering and dying away, it grows quickly round the egg, putting on a round tough covering. Soon the egg hatches, and the baby insect finds itself inside a growing nurserv, with plenty of food all round. it. When it is full-grown, it bores its way out of the marble ‘‘gall," and is ready to start life. So you see, when you find an. oak-apple, if it has a little round hole anywhere, you may be sure ~the baby gall-wasp has flown; but if it is imtact the baby is still in its nursery.
