“We’ll strike off from the black rock,” said Dick. “When we were following you we kept going around in a circle, but I think I can strike a straight line to the wall; after that it will be dead easy, for all we have got to do is to follow the wall around.”
They soon reached the black rock and Dick again showed them the trail.

“I’m sure I’m right,” said Clara. “How can you know that I am not?”
“Listen!” replied Dick.
“I hear something like the pawing of a horse,” said Charley.
