its adversaries, gathering itself to attack them. Only a few seconds had passed. Confused thoughts swept Alan. This fly with its growth would soon fill this room. Burst it; burst upward through a wrecked palace; soar out, and by the power of its size alone devastate this world.[Pg 72] [Pg 72] He heard himself shouting, "Father, get back! It's too large! I've got to kill it!" Could he wrestle with it and hope to win? Alan edged around the center table. He was bathed in cold sweat. This thing was horrifying! The fly was already half the length of his own body. In a moment it might be twice that! He was aware of Glora pulling at him, and his father rushing past him with a bottle of liquid, shouting: "Alan! Run! You and the girl, get out of here! Into the other room—" Then Alan saw the things on the floor! His foot crushed one with a slippery squash! Nameless, hideous, noisome things grown monstrous, risen from their lurking invisibility in the drops of water! Sodden, gray-black and green-slimed monsters of the deep; palpitating masses of pulp! One lay rocking, already as large as a football with streamers of ooze hanging from it, and squirting a black inky fluid. Others were rods of red jelly-pulp, already as large as lead pencils, quivering, twitching. Disease germs, these ghastly things, enlarging from the invisibility of a drop of water! The fly landed with a thud on the center table. The fumes of the shattered bottle of chemicals were choking Alan. He flung himself toward the monster fly, but Glora held him. "No! Escape to the other room!" Dr. Kent was stamping the things upon the floor; pouring acids upon them. Some eluded him. The air in the room was unbreathable.... Alan and Glora reached the bedroom. The laboratory was a hideous chaos. They were aware of its outer door opening, disclosing the figure of Polter who, undoubtedly, had been attracted by the noise. He shouted a startled oath. Alan heard it above the beating wings of the monstrous fly. Things lurched at the opened door; Polter banged it upon[Pg 73] them and rushed away, shouting the alarm through the palace. [Pg 73] Dr. Kent was stammering, "Not the enlarging drug, Glora, child, the other! Hurry!"
