"I saw nothing," he said; whereupon like lightning, the Italian's manner changed. His concern vanished and he laughed aloud.

"What a fool—what a fool am I! It was the shadow of the shrine!"

"You've got the red man on your nerves, I guess. I don't blame you. What did you think you saw?"

He stopped, kept his eye on Giuseppe and took a pinch of snuff.

"Maybe we'll get a move on to-morrow," he said.

Doria, now self-possessed but fallen taciturn, smiled at him and his white teeth shone through the gloom.
