Nelson nodded. "All over but the cheering," he replied with that strange, macabre humor which often comes to solace men about to die.

"See you in church." There was an equally gallant lightness to Alden's reply.

The dark haired pilot, with a curious, detached sense of unreality, stepped into the middle of the room, the automatic in his hand seeming no more potent than a water pistol, for a ponderous, lambent eyed monster was now hopping forward. While minute particles of dust and dirt rained down from the disappearing barrier, the foremost allosaurus opened its enormous jaws, uttered an eery scream and charged straight at the unbarred cell.

Drawing a deep breath, Nelson raised the .45, sighted, and, remembering his former experience, fired at the enormous right eye. As in a dream, he felt the recoil. The monster neither slowed nor swerved in the least, though its great, saucer-like eye disintegrated horribly. Immediately Nelson swiftly sighted at the other eye and fired, just as the allosaurus' shadow filled the threshold.

Crack! A swirl of bitter smoke stung the aviator's staring eyes. He'd hit; he knew it!


yclopean moments followed as the blinded monster dashed forward, missed the circular door, and, butting his head against the stone wall to the left, fell completely stunned, effectively blocking the doorway with its huge body. One enormous hind leg, fully ten feet long, and equipped with three razor-like claws, projected into the cell and lashed aimlessly back and forth, forcing the two prisoners to dodge wildly.

There ensued that indescribable kind of a moment when men go mad. Outside the cell the ravenous herd pounced upon their fallen mate and with hideous grunts and snarls promptly commenced to tear it apart. The shaken prisoners realized that the rending jaws would before long undoubtedly remove the temporary obstacle; but meanwhile the hideous hissing and the fetid stench of the allosauri breath made the cell a mad-house.

Gradually, the gigantic carcass at the door commenced to quiver and roll violently under the ferocious tugs of the eager feasters. A gap of light appeared over the huge haunches, and, all at once, another of those terrible heads slipped over the carcass and into the cell.
