“The tunnel runs both ways from the bottom of this shaft,” explained Ned. “One end is right under the house but the other is some distance out under the lake-bottom—I don’t know just how far it extends, although I’ve been down through it several times. Probably Coleson is down there now with his pick and shovel. He fills a dump car with ore, hauls it to the bottom of the shaft and hoists it with this rigging,” and Ned indicated a rusty windlass which stood at the edge of the pit.

“Some job turning that crank,” murmured Dave Wilbur, as he eyed the dilapidated mechanism.

“Yeah, it would be a lot wors’n turning a grindstone,” chuckled Tommy Beals. “By the way, Weary, when are you going to finish that job on Ned’s axe?”

“D’j’ever hear about the man who ‘always had an axe to grind’?” drawled Wilbur.

“What does Coleson do with the ore after he gets it to the surface?” asked Dick, who was still staring down into the mine.

“He loads it onto a truck and runs it up to the smelter at Cleveland,” explained Rogers. “There’s only about one load a week, because it’s mighty slow work knocking chunks off the walls of the tunnel, and they don’t dare fire a blast for fear of bringing down the roof of the mine and the lake with it. There’s no money in this kind of mining, and I don’t see how Coleson makes enough to keep him from starving.”

“You’re right!” exclaimed Tommy Beals, with an expression of genuine concern on his plump features. “And speaking of starvation reminds me that—”

“That you’ve been dieting for almost four hours and are about to pass out of the picture,” laughed Ned. “All right, boys,” he continued, “if Dick has seen enough, let’s save Fatty’s life right now by heading back for home and supper.”

CHAPTER III
THE HAUNTED MINE

Dave Wilbur was washing the flivver—or, to be entirely accurate, Dave was playing the hose on the car while Tommy Beals and Charlie Rogers wielded sponge and rag in an effort to remove mud and road oil. The job was nearly completed when Ned Blake and Dick Somers vaulted the back fence and joined the group.
