"Here goes," he said.

He pulled the lever to full power and with a roar which almost deafened us in the small flyer, the ray leaped out to do its deadly work. I watched through a port beside the motor. There was a flash of intense light for an instant and then the motor died away in silence. A path to freedom lay open before us. Jim started one of the stern motors and slowly we forced our way through the hole torn in the living mass. When we were almost at the surface, he threw in full power and we shot free from the amoeba and into the open. Again we were stopped in midair and drawn back toward the huge bulk. The eyes looked at us and we were turned around. As the ray swung into a position to point directly toward one of the eyes, Jim pulled the controlling lever. With the flash of light which ensued, the eye and a portion of the surrounding tissue disappeared. The amoeba writhed and changed shape rapidly, while flashes of brilliant crimson played over the remaining eyes. Again the ray was brought into play and another of the eyes disappeared. This was evidently enough for our captor, for it suddenly released us and instantly we started to fall. Jim caught the control levers and turned on our power in time to halt us only a few feet above the plain toward which we were falling. We were close to the point whence we had started up and we could see that the battle below us was still raging.


The green dragon was partially engulfed by the amoeba, but it still relentlessly tore off huge chunks and devoured them. The amoeba was greatly reduced in bulk but it still fought gamely. Even as we approached the dragon was evidently satiated, for it slowly withdrew from the purple bulk and back away. Long feelers shot out from the amoeba's bulk toward the dragon but they were bitten off before they could grasp their prey.

"Let's get away from here, Jim," I cried, but I spoke too late. Even as the words left my mouth the green dragon saw us and raised itself in the air, and with gaping jaws launched itself at us. It took Jim only a moment to shoot the flyer up into space, and the charge passed harmlessly beneath us. The dragon checked its headway and turned again toward us.

"Use the machine-gun, Pete!" cried Jim. "I've got to run the ship."

I threw the cover off the gun and fed in a fresh belt of ammunition. As the green monster dashed toward us I hastily aligned the gun and pulled the trigger. My aim was good and at least fifty of the bullets plowed through the approaching bulk before Jim dropped the ship and allowed it to pass above us. Again the dragon turned and charged, and again I met it with a hail of bullets. They had no apparent effect and Jim dropped the ship again and let the huge bulk shoot by above us. Twice more the dragon rushed but the last rush was less violent than had been the first three.

"The bullets are affecting him, Pete!" cried Jim as he shot the flyer upward. "Give him another dose!"

I hastily fed in another belt, but it was not needed. The dragon rushed the fifth time, but before it reached us its velocity fell off and it passed harmlessly below us and fell on a long curve to the plain below. It fell near the purple amoeba which it had battled and a long feeler shot out and grasped it. Straight into the purple mass it was drawn, and vanished into the huge bulk.

Jim started one of the stern motors. In a few seconds we were far from the scene.
