The robot chuckled. "Not for a long time! Certainly not when they know I'm around. Those babies have given me a wide berth so far." He added: "I've been intending to pay a visit to your side of the world, but I could tell those dark-skinned brutes were up to something. I decided to hang around and await developments."

"But Ketrik"—Janus hesitated—"what's this about your body?"

"Don't worry, it's safe. This is only the mental part of me. Sure, there's a huge temple about ten miles back, with dozens more of these robots standing around idle." A sudden thought occurred. "Want to take a look? I could carry you across the heavy gravity."

"No thanks!" Janus declined. "My scientific interest doesn't go that far. Maybe the Professor, here—"

"Sure!" Brownell came forward, eager.

"I'll go too," Mark said. "I'd like to see how those robots work."

Ketrik extended a huge hand. Brownell and Mark clung tightly as it swung them up. With the two men perched on its shoulders, the robot went striding back through the forest.

The temple, massive and pillared, rested in a wide clearing.

They saw the robots, dozens of them lining the walls. The quartz discs of their eyes were now dull and lifeless. And near each robot, fifty feet high in the wall, were alcoves.

"Gravity here is normal!" Mark noticed suddenly.
