it quiet, George Rankin. And you, Mistress Mary; you will both be quite safe with Migul if you are docile."
Tugh stood before us. We were in a dim recess of a great cavern with the throb of whirring machinery around us. It was the same day which I have just described; Larry was at this moment asleep in the palace room. Tugh and Tina had come searching for Migul; and Tugh had contrived to send Tina back. Then he had come directly to us, finding us readily since we were hidden where he had told Migul to hide us.
This cavern was directly beneath the Robot laboratory in which the Time-traveling cage was placed. A small spiral stairway led downward some two levels, opening into a great, luridly lighted room. Huge inert machines stood about. Great wheels were flashing as they revolved, turning the dynamos to generate the several types of current used by the city's underground industrial activities.
It was a tremendous subterranean room. I saw only one small section of it; down the blue-lit aisles the rows of machines may have stretched for half a mile or more. The low hum of them was an incessant pound against my senses. The great inert mechanisms had tiny lights upon them which gleamed like eyes. The illumined gauge-faces—each of them I passed seemed staring at me. The brass jackets were polished until they shone with the sheen of the overhead tube lights; the giant wheels flashed smoothly upon oiled bearings. They were in every fashion of shape and size, these inert machines. Some towered toward the metal-beamed ceiling, with great swaying pendulums that ticked like a giant clock. Some clanked with eccentric cams—a jarring rhythm as though the heart of the thing were limping with its beat. Others had a ragged, frightened pulse; others stood placid, outwardly motionless under smooth, polished cases, but humming inside with a myriad blended sounds.
nert machines. Yet some were capable of locomotion. There was a small truck on wheels which were set in universal joints. Of its own power—radio controlled perhaps, so that it seemed acting of its own volition—it rolled up and down one of the aisles, stopping at set intervals and allowing a metal arm lever in it to blow out a tiny jet of oil. One of the attending Robots encountered it in an aisle, and the cart swung automatically aside. The Robot spoke to the cart; ordered it away; and the tone of his order, registering upon some sensitive mechanism, whirled the cart around and sent it rolling to another aisle section.
The strange perfection of machinery! I realized there was no line sharply to be drawn between the inert machine and the sentient, thinking Robots. That cart, for instance, was almost a connecting link.
There were also Robots here of many different types. Some of them were eight or ten feet in stature, in the fashion of a man: Migul was of this design. Others were small, with bulging foreheads and bulging chest plates: Larry saw this type as domestics in the palace. Still others were little pot-bellied things with bent legs and long thin arms set crescent-shape. I saw one of these peer into a huge chassis of a machine, and reach in with his curved arm to make an interior adjustment....
Migul had brought Mary Atwood and me in the larger cage, from that burned forest of the year 762, where with the disintegrating ray-gun Tugh had killed Harl. The body of Harl in a moment had melted into putrescence, and dried, leaving only the skeleton within the clothes. The white-ray, Tugh had called his weapon. We were destined very shortly to have many dealings with it.
