he contrivance, with him on it, was wheeled toward the barred door. It was halted at a spot marked on the floor, about thirty feet from the bars. The Rogan leader stepped alongside the rack, with Greca trembling beside him.
Dex closed his eyes for a moment, grimly marshaling strength of will to go through the trial that was just beginning.
The Rogan leader depressed another lever in the rock wall. The barred door slid slowly up, to reveal the receding darknesses of some great cave, or room, that adjoined the laboratory. Dex rolled his eyes so that he could watch the doorway; and, in a cold perspiration, waited for whatever might appear.
It was not long in coming!
The reptilian smell suddenly grew stronger. There was a booming hiss, a savage bellowing. A clattering of vast scales rattled out as some body weighing many tons was dragged over rock flooring. Then, before Dex's staring eyes appeared a huge, wedge-shaped head, at sight of which he bit his lips to keep from crying aloud.
Often enough he had seen one of those terrific heads looming in the fog of the northern hemisphere of Jupiter. He did not know the genus of the vast monster that bore it, but he did know it for the fiercest of the lizard giants that roamed the Jovian jungles. A creature larger than a terrestrial whale, with great long neck and heavy long tail dragging yards behind it, it would find the puny bulk of a man nothing but a morsel in its jaws!
Again the gigantic thing hissed and bellowed. And then its huge head came through the six-foot door and its neck uncoiled to send the gaping jaws within a foot of Dex. There it struggled to reach him, prevented by the small doorway that restrained the bulk of its enormous body, its head only inches away from the cleverly measured spot to which the metal rack had been wheeled.
