“Poor fellow,” said Hal softly. “He has worn himself out.”

“Yes,” said Chester, “and had we not brought him along, we would still be prisoners in the cavern, with our death only a question of days or hours.”

“True,” said Hal. “And such strength,” he added, “I never saw before.”

“Nor do I ever expect to see again,” said Chester.

Now Alexis stirred and groaned. Then he sat up.

“What has happened?” he demanded.

“Through your prowess and bravery,” Hal made answer, “we have escaped.”

Alexis jumped to his feet and patted himself on the chest.

“It is true,” he said, “I am a brave man; and I am a strong man, am I not?”

“There can be no question about either,” replied Hal.
