"They seem to be listening—and waiting!" whispered the girl uneasily.

Conan rang his hilt against one of the images.

"Iron," he pronounced. "But Crom! In what molds were they cast?"

He shook his head and shrugged his massive shoulders in puzzlement.

Olivia glanced timidly about the great silent hall. Only the ivy-grown stones, the tendril-clasped pillars, with the dark figures brooding between them, met her gaze. She shifted uneasily and wished to be gone, but the images held a strange fascination for her companion. He examined them in detail, and barbarian-like, tried to break off their limbs. But their material resisted his best efforts. He could neither disfigure nor dislodge from its niche a single image. At last he desisted, swearing in his wonder.

"What manner of men were these copied from?" he inquired of the world at large. "These figures are black, yet they are not like negroes. I have never seen their like."

"Let us go into the sunlight," urged Olivia, and he nodded, with a baffled glance at the brooding shapes along the walls.

So they passed out of the dusky hall into the clear blaze of the summer sun. She was surprized to note its position in the sky; they had spent more time in the ruins than she had guessed.

"Let us take to the boat again," she suggested. "I am afraid here. It is a strange evil place. We do not know when we may be attacked by whatever cast the rock."

"I think we're safe as long as we're not under the trees," he answered. "Come."

The plateau, whose sides fell away toward the wooded shores on the east, west and south, sloped upward toward the north to abut on a tangle of rocky cliffs, the highest point of the island. Thither Conan took his way, suiting his long stride to his companion's gait. From time to time his glance rested inscrutably upon her, and she was aware of it.
