A small wasp is now seen hovering about the flowers, and we must turn our attention to him as seen in Figs. 1, 2, and 3. The insect alights, we will assume, on a blossom of the second day (Fig. 1), clinging with all his feet, and thrusting his tongue into the beads of nectar shown at A^1 and B^1. He now brings his breast or thorax, or perhaps the underside of his head against the pollen, and is thoroughly dusted with it. Leaving the blossom, we see him in flight, as at Fig. 2, and very soon he is seen to come to a freshly opened flower, which he sips as before. The pollen is thus pushed against the projecting stigma, as shown at Fig. 3, and thus, one by one, the flowers are cross-fertilized. The stigma, after receiving pollen, immediately bends downward and backward, as shown in B^1, to give place to the ripening anthers, and shortly after the last pair of them have shed their pollen the blossom, having then fulfilled its functions, falls off, as shown at D. This may be on the afternoon of the third day, or not until the fourth. If not visited by insects it may chance to remain the longer time; but more than one tiny wasp gets his head into such a blossom, and is surprised with a tumble, his weight pulling the blossom from its attachment. [Illustration: Fig. 2] [Illustration: Fig. 3] The result of that pollen upon the stigma is quickly seen in the growing ovary or pod, which enlarges rapidly on the few succeeding days, as in E. [Illustration: E] Many species of hornets and wasps, large and small, are to be seen about the figwort blooms, occasionally bees, frequently bumblebees, which usually carry away the pollen on the underside of their heads. Who shall any longer refer to the figwort as an "uninteresting weed"? Two Fairy Sponges
