A soft and pliable leather harness fitted snugly about his waist--but as he stretched himself up from his cot he saw that his gear lacked the multitude of cryptic studs and instruments with which the scientist's had been decked. Then, "Larry--you're all right?" Sandra Day, who had leaped to her feet as Larry stirred, flew across the room. Her clothing, too, had been supplanted by that of the later era. Her harness differed from Larry's only in the addition of a cupped breast-girdle similar to that once worn by Egyptian women. Leather, soft and white and pliant, clung closely to her slim, lithe body. As Larry looked at her, she faltered. A slow flush mantled her cheeks. Harg moved forward, a delighted gleam in his protruding eyes. "Modesty!" he said in a tone of enchantment. "Sex shame! Imagine! And we had believed that it died out long before the Machine Era. It would be interesting to mate you two young people and--" He stroked his temple thoughtfully. "But we will think of that later. Come, my dear young savages. Let me show you my _other_ experiments." Larry's eyes, smoldering rebellion, sought those of Sandra. The girl's cheeks still flamed with a high pride, but she nodded almost imperceptibly, cautioning him to cause no immediate trouble. He grunted, "Okay, let's go. What is there to see?" The chamber in which he had awakened was a square box of metal, lighted from above by concealed globes of cold light. No windows or doors marred the smooth luster of the walls. But as Harg stepped forward and touched his fingers to a spot on the wall briefly, a section slid back, exposing a brilliantly lighted corridor beyond. Silently the three moved into the passage, Larry bringing up the rear. As he passed through the portal, he studied it cautiously. If he could only learn the secret of the operation of that door.... "It would do you," Harg interrupted his scrutiny, "no good, of course. This is but one of many inner chambers. There are many other doors and many guards to pass. Moreover, you cannot return to your Time ever--without my help." Larry started guiltily. The man was uncanny! He seemed to be able to read thoughts! "Now, here--" said Harg, "are the results of some of my earlier attempts to bring life-samples through the Time warp." They had turned a corner and entered into a long chamber walled into sections. In each section there was an animal of some sort. So lifelike were the postures of these beasts that Larry half expected a cacaphony of protest to greet their entrance. But the creatures were stiff, silent. Harg smiled his white-gummed, toothless smile. "Dead," he said regretfully. "All of them. Their bodies survived the passage through the Time warp. But when they arrived, the spark had gone. We have identified most of them. But some still puzzle us." * * * * *
