"Is that a guess, or a piece of positive information?"
"It's a guess," laughed Sandy, drawing on his shoes and walking softly across the bare floor in the direction of the shaft.
The boys passed out of the sleeping chamber into a passage which led directly to the shaft of the mine. This shaft was perhaps twenty feet in width. It included the air shaft, the division where the pumps were operated, and two divisions for the cages which lifted the coal from the bottom of the mine. The pumps were not working, of course, and no air was being forced down.
One of the cages lay at the top so the other must have been at the bottom of the shaft. As the boys looked down into the shaft, Tommy seized his chum by the arm and whispered:
"Did you see that light down there?"
"Light nothing!" declared Sandy.
"But I did see a light!" insisted the other.
"Perhaps you did," replied Sandy, "but if there's any light there it's merely a reflection from our electrics. There may be a metallic surface down there which throws back the light rays."
"Have it your own way!" grunted Tommy. "You know yourself that the caretaker said there were lights in the mine which no one could account for and he especially mentioned the light in Tunnel Six.
"All right!" Sandy grinned. "We'll sneak down so quietly that any person who happens to be at the bottom of the shaft with the light will never suspect that we are within a hundred miles of the place. We may be able to geezle the fellow that's making the ghost walk around here nights."
