He entered the ship and dashed down the winding staircase to the water purifiers to change the water in the reservoir tanks. Thirsty as he was, he was not going to take a drink until the water had been cleared of the knockout drug he had dropped into the tanks.

After that came the laborious job of getting everyone in the ship strapped into their bunks for the takeoff. It took the better part of an hour to get all sixty of them up—they had fallen all over the ship—and nestled in the acceleration cradles. When the job was done, he went to the main control room and set the autopilot to lift the spaceship high into the ionosphere.

Then, sighting carefully on the valley far below, he dropped a flare bomb.

"Goodbye, little monsters," he said exultantly.

For a short space of time, nothing happened. Then the viewplate was filled with a deadly blue-white glare. Unlike an ordinary atomic bomb, the flare bomb would not explode violently; it simply burned, sending out a brilliant flare of deadly radiation that would crisp all life dozens of feet below the ground.

He watched the radiation blazing below. Then it began to die down, and when the glare cleared away, all was quiet below.

The valley was dead.

When it was all over, Wayne took the hypodermic gun from his pouch, filled it with the anti-hypnotic drug that he had taken from the medical cabinet, and began to make his rounds. He fired a shot into each and every one aboard. He had no way of knowing who had been injected by the small monsters and who had not, so he was taking no chances.

Then he went to the colonel's room. He wanted to be there when the Commanding Officer awoke.
