“Too many echoes here,” declared the captain. “A fellow can’t tell where the cry comes from.”
“Well, let us investigate,” said our hero.
They moved forward and backward, up one passageway and down another, calling and listening. At times the voice seemed to be quite close, then it sounded further off than ever.
“This sure is a mystery!” declared Phil. “What do you make of it, Dave?”
“I am beginning to think the call came from somewhere overhead,” answered our hero. “Captain, see if you can flash a light on those rocks to the left of our heads.”
Captain Sanders did as requested, and presently all in the party saw another passageway, leading up from a series of rocks that formed something of a natural stairway. Up this they went, Dave leading the van. Then they came to a small opening between two rocks.
“Help! help!” came in a half-smothered voice. “Help, please. Don’t leave me here in the dark any longer!”
