"My foot hurts," said Durkin suddenly, breaking the silence.

"I'm going out and see what happens," said Maget.


urkin limped after Maget, who now took the lead. They crept close as possible to the mine opening, and saw the big Portuguese standing there in silence, listening carefully. Any sounds the two might have made were drowned in the great bellowing from within the cavern.

These noises, so like the croak of bullfrogs but magnified a thousand times, were terrifying to the heart.

The sweep of wings sounded on the night air, and Espinosa drew back and squatted close to the ground, as immense green creatures, flying on dusty wings, issued from the mine.

"God, those are moths," breathed Maget.

Yes, unmistakably, they were moths, as large as condors. The green ones, but for their size, were lunar moths, familiar enough to the two tramps. More bats came, disturbed by the entrance of the two Gurlones.

Durkin broke, then. "I'm—I'm—I guess you're right, Maget," he whispered, in a terrified voice. "We should have never come. If my foot wasn't hurt, I'd start for the river now. Curse it, what a place!"
