hile the terrific shrieks of the wretches across the court rang to the copper-hued sky, the two Americans remained in doubt; then all at once the chill of death gripped their hearts, as they saw the bars of that cell directly opposite slowly but surely rising! Uttering heart-rending cries, the doomed prisoners clung frantically to stay the vanishing barrier separating them from those appalling man-eaters. But, disdainful of their pitiful efforts, the bronze bars rose relentlessly with metallic rattlings and janglings from some unseen mechanism.
Rooted to the floor, both Americans watched the distant grille vanish into the upper stone-work and heard the ghastly hissing as the allosauri herd commenced to move forward. Sick and shaken, Nelson beheld one of the doomed men cling in desperation to the bars; he was lifted clear of the floor and borne towards the ceiling, meanwhile venting his terror with such screams as could otherwise have risen only from an inquisitor's torture chamber.
The tragedy was swiftly completed. Half a dozen of the nearest allosauri, taller than any giraffes, suddenly sprang forward, their long, naked tails rising as their gait increased. Snarling horribly, the vast slate-colored beasts plunged into the cell, terminating shrieks of mortal terror. Backs broader than bus tops squirmed and tugged, then one of the loathsome monsters reappeared carrying in its dripping jaws a mangled, yet struggling victim much as a cat carries a mouse. In a trice the other allosauri came rushing eagerly up, seeking to snatch the prey from the first monster.
Nelson stiffened. "Great God! And that's what'll happen to us!"
eakened by his head wound, and blind with nausea, he stumbled to the rear of the cell to collapse upon a pile of foul straw, littered with equipment which the superstitious captors must have condemned together with the owners.
Nelson sank upon them, then stiffened, for his outflung hand had encountered a hard, familiar outline. It was a .45 automatic pistol.
