“True; but he may have decided to remove the treasure to some other hiding place!”
“Right!” cried Harding, nervously. “I appreciate the danger of procrastination, Mr. Reade. I am ready when you are.”
“But you must first direct us where to find the treasure cave.”
“That I will do, but——”
“What?”
“You cannot go thither with this air-ship.”
“Why?”
“It is buried deep in a dark and unwholesome cavern. The air-ship cannot enter that.”
“That is all right,” said Frank. “We can leave the ship and return to it when we have secured the treasure.”
“Certainly.”
