"You don't believe me, do you?" The impatience arose hotly in that demand.

"Why shouldn't I?" Shann tried to temporize. "You've had a lot of exploration experience; you should know about such things. I don't pretend to be any authority."

Thorvald refolded the map and placed it in the case. Then he pulled at the sealing of his blouse, groping in an inner secret pocket. He uncurled his fingers to display his treasure.

On his palm lay a coin-shaped medallion, bone-white but possessing an odd luster which bone would not normally show. And it was carved. Shann put out a finger, though he had a strange reluctance to touch the object. When he did he experienced a sensation close to the tingle of a mild electric shock. And once he had made that contact, he was also impelled to pick up that disk and examine it more closely.

The carved pattern was very intricate and had been done with great delicacy and skill, though the whorls, oddly shaped knobs, ribbon tracings, made no connected design he could determine. After a moment or two of study, Shann became aware that his eyes, following those twists and twirls, were "fixed," that it required a distinct effort to look away from the thing. Feeling some of that same alarm as he had known when he first heard the wailing of the Throg hound, he let the disk fall back into Thorvald's hold, even more disturbed when he discovered that to relinquish his grasp required some exercise of will.

"What is it?"

Thorvald restored the coin to his hiding place.

"You tell me. I can say this much, there is no listing for anything even remotely akin to this in the Archives."

Shann's eyes widened. He absently rubbed the fingers which had held the bone coin—if it was a coin—back and forth across the torn front of his blouse. That tingle ... did he still feel it? Or was his imagination at work again? But an object not listed in the exhaustive Survey Archives would mean some totally new civilization, a new stellar race.

"It is definitely a created article," the Survey officer continued. "And it was found on the beach of one of those sea islands."
