He remembered the shapes that swam and crept in the green water gardens, with whirling cilia and great, cold, glistening eyes. And he remembered the clean, empty fish bowl in the window downstairs. "Don’t let them, Dad," said Harry convulsively. "You’ve got to kill them all. The ones here and the ones in the pond. You’ve got to kill them good—because they don’t mind being killed, and they lay lots of eggs, and their eggs can stand almost anything, even drying up. _And the eggs remember what the old ones knew._" "Don’t worry," said Henry Chatham quickly. He grasped his son’s hand, a hot limp hand that had slipped from under the coverlet. "We’ll stop them. We’ll drain the pond." "That’s swell," whispered the boy, his energy fading again. "I ought to have told you before, Dad—but first I was afraid you’d laugh, and then—I was just ... afraid...." His voice drifted away. And his father, looking down at the flushed face, saw that he seemed asleep. Well, that was better than the sick delirium—saying such strange, wild things— Downstairs the doctor was saying harshly, "All right. All right. But let’s have a look at the patient." Henry Chatham came quietly downstairs; he greeted the doctor briefly, and did not follow him to Harry’s bedroom. When he was left alone in the room, he went to the window and stood looking down at the microscope. He could not rid his head of strangeness: A window between two worlds, our world and that of the infinitely small, a window that looks both ways. After a time, he went through the kitchen and let himself out the back door, into the noonday sunlight. He followed the garden path, between the weed-grown beds of vegetables, until he came to the edge of the little pond. It lay there quiet in the sunlight, green-scummed and walled with stiff rank grass, a lone dragonfly swooping and wheeling above it. The image of all the stagnant waters, the fertile breeding-places of strange life, with which it was joined in the end by the tortuous hidden channels, the oozing pores of the Earth. And it seemed to him then that he glimpsed something, a hitherto unseen miasma, rising above the pool and darkening the sunlight ever so little. A dream, a shadow—the shadow of the alien dream of things hidden in smallness, the dark dream of the rotifers. The dragonfly, having seized a bright-winged fly that was sporting over the pond, descended heavily through the sunlit air and came to rest on a broad lily pad. Henry Chatham was suddenly afraid. He turned and walked slowly, wearily, up the path toward the house. *END* _Transcribers note_: This etext was produced from IF Worlds of Science Fiction March 1953.
