But the Thing that came behind the _Thought_ was a ship, a little ship of the same misty white, and it flowed into, and through the wall, and was within their prison. The Thessian ships turned their rays toward it, and waited. What was this thing? The ovaloid ship which drifted so slowly toward them suddenly seemed to jerk, and from it reached pseudopods! An amoeba on a titanic scale! It writhed its way purposefully toward the nearest ship, and while that ship waited, a pseudopod reached out, and suddenly drove through the four foot relux armor! A second pseudopod followed with lightning rapidity, and in an instant the ship had been split from end to end! Now a hundred rays were leaping toward the thing, and the rays burst into fire and gouts of light, blackened, burned pseudopods seemed to fall from the thing and hastily it retreated from the enclosure, flowing once more through the wall that stopped their rays. But another Thing came. It was enormous, a mile long, a great, shining scaly thing, a dragon, and on its mighty neck was mounted an enormous, distorted head, with great flat nose and huge flapping nostrils. It was a Thessian head! The mouth, fifty feet across, wrinkled into an horrific grin, and broken, stained teeth of iron showed in the mouth. Great talons upraised, it rent the misty wall that bound them, and writhed its awful length in. The swish of its scales seemed to come to the watchers, as it chased after a great battleship whose pilot fled in terror. Faster than the mighty spaceship the awful Thing caught it in mighty talons that ripped through solid relux. Scratching, fluttering enormous, blood-red wings, the silvery claws tore away great masses of relux, sending them flying into space. Again rays struck at it. Cosmic and moleculars with blinding pencils of light. For now in the close space of the Wall was an atmosphere, the air of two great warships, and though the space was great, the air in the ships was dense. The rays struck its awful face. The face burst into light, and black, greasy smoke steamed up, as the thing writhed and twisted horribly, awful screams ringing out. Then it was free, and half the face was burned away, and a grinning, bleeding, half-cooked face writhed and screamed in anger at them. It darted at the nearest ship, and ripped out that ray that burned it--and quivered into death. It quivered, then quickly faded into mist, a haze, and was gone! A last awful thing--a thing they had not noticed as all eyes watched that Thing--was standing by the rent in the Sphere now, the gigantic Thessian, with leering, bestial jaws, enormous, squat limbs, the webbed fingers and toes, and the heavy torso of his race, grinning at them. In one hand was a thing--and his jaws munched. Thett's men stared in horror as they recognized that thing in his hand--a Thessian body! He grinned happily and reached for a battleship--a ray burned him. He howled, and leaped into their midst.
