"What is the matter now?" the Jaguar asked.

"I do not know," the American answered; "but I fancy that we shall soon be informed."

In fact, the sentry had challenged; and, after an apparently satisfactory reply, a horseman entered the camp.

"A flag of truce!" Lanzi said, appearing in the doorway of the jacal.

"A flag of truce!" the Jaguar repeated, giving John Davis a glance of surprise.

"Perhaps it is the help you expect from heaven, and which has been sent you," the American answered.

The young man smiled incredulously, but turned to Lanzi and said,

"Let him enter."

"Come, señor," said the half-breed, addressing a person who was still invisible; "the Commandant is ready to receive you."

Lanzi fell back, and made room for an individual who at once entered. The Jaguar started on recognising him. It was Sandoval, who had delivered him the letter on the previous day. The Pirate Chief bowed politely to the two persons in whose presence he found himself.
