"Then I will say nothing about it."

"Useless, angelito! Cocom knows that no other person than ourselves would dare to steal the Chalchuih Tlatonac. I was with him all the time, so he will know it cannot be me. Naturally enough, he will think it is you."

"And therefore betray us?"

"No, I do not think he will do that. After all his trouble, it would be foolish of him to now play the traitor, for then his concurrence in our escape would become known, and get him into bad odour with the priests. But it is possible that he might insist on your leaving the opal behind, to be sent back to Totatzine."

"No," cried Dolores, decisively; "I will rather throw it into the sea. Now that the gem is away from the shrine, those horrid priests may stop sacrificing men to the idol. Besides," she added, naïvely "it is mine."

"Ah! that is an all-sufficient reason," replied Duval, smiling. "Like all women, querida, you are fond of gems, and do not like to part with this one."

"It is very beautiful," sighed Dolores, taking the stone from her breast. "See how it glitters, Juanito. Ah! what is that?"

A long, shrill whistle sounded outside the cave.

"Cocom!" cried Jack, starting to his feet. "Hide the opal for the present, Dolores."

It was indeed Cocom who entered. Cocom looking much older than usual, and quite worn out with his long journey from Totatzine. He saluted them gravely, and wrapping himself in his zarape crouched on the floor of the cave, with his eyes intently fixed on them both. The expression of his face was as usual, and Jack was quite unable to decide whether he approved of or resented the rape of the shining precious stone.
