It was now almost dark, however, and the youths, after resting a few moments, were about to turn and start for the patriot encampment when to their hearing came a muffled cry for help.
“Listen!” exclaimed Dick.
“Somebody cried ‘help,’” said Tom.
“Yes, but where did the voice come from?”
“It sounded to me as if it came from below us, somewhere.”
“That’s the way it seemed to me.”
Dick and Tom dropped down on their knees, and peered downward, and Dick called out, loudly:
“Hello, down there! Where are you?”
“In the cave,” came back to their ears, in a muffled, faint voice. “In behind the earth that has closed up the entrance to the cave.”
“Well, that is queer!” exclaimed Tom. “Somebody was in the cave when the bank caved off, and is a prisoner there.”
