Sarkoff glanced up at Thulon who was still standing in the lock looking down at the men before him. There was a ghost of a smile on his face.

"See!" said Sarkoff, addressing Thulon. "I told you we couldn't tell these boys anything. They have to see, they have to feel, they have to be shown."

"Well," the thought came from Thulon to everyone. "Why don't you show them?"

"Okay," Sarkoff answered. "Nevins!" he shouted. "Reese! Come out of that ship."

Nevins and Reese were the two engineers who had died with Sarkoff.

Thulon moved a little to one side. Nevins and Reese came out of the ship. They were grinning.

"Feel us!" Sarkoff shouted. "Pinch us. Cut off a slice of skin and examine it under a microscope. Make blood tests. Use X-rays. Do whatever you damned please." He shoved a brawny arm under Nielson's nose. "Here. Pinch this and see if you think it's real."

Nielson shrank away.

Nevins and Reese passed among the men, offering themselves in evidence. Startled voices called softly in answer to other startled voices. "They're real."

"This is no lie. This is the truth."
